Service & Maintenance

Contents


Take our word for it ....

Prevention is better than Cure

The old adage “a stitch in time, saves nine” is an

understatement in the context of boiler maintenance.

With boilers often in constant service and fulfilling critical

heating functions within buildings ranging from domestic

residences to major airports, it makes sense to keep them

running at peak performance. Unfortunately, all too often,

boiler maintenance remains unscheduled and overlooked

until boiler failure becomes a reality and a lack of heating

starts impacting on people and critical functions throughout

the household or organisation.

Annual Service

Every boiler, cooler and pump requires maintenance to

ensure reliable and efficient operation. An un serviced

system can quickly become a costly asset, experiencing

premature failures that can damage both the system and

potentially the surrounding areas. Regular preventative

maintenance will ensure optimum performance is being

achieved and running costs are being kept to a minimum.

Our nationwide service network offers fixed price,

tailored service contracts to allow you to budget for the

maintenance of your plant with confidence, while our

extensive range of spare parts can be relied upon at any

time - even long after your purchase. Tailored service

contracts mean that you only pay for the level of servicing

you require and the fixed price enables you to budget for the

cost of the plant over the coming years.

Key reasons for having your boiler serviced annually

1. Regulatory Compliance – Government regulations set

out minimum service requirements for all commercial

buildings in order to meet health and safety standards.

These regulations also stipulate how long service

records should be kept. Annual servicing of your

heating plant and maintenance of accurate service

records provides a level of insurance not only against

heating failure but against costly litigation resulting

from an appliance rendered dangerous through

neglect.

2. Keeping your building safe – Having your boiler

serviced helps to highlight any potential dangers and

risks associated with your boiler and flue. When your

boiler stops working efficiently, it’s possible for toxic

carbon monoxide gases to be released. These gases

are extremely dangerous and pose serious risks to

anyone exposed to them, yet are ordinarily hard to

detect.

3. Identify Problems Early – During a service, potential

problems are identified early and can help to minimise

further damage to the boiler and save costly future

repairs.

4. Reduce your Fuel Bills – During an annual boiler

service, your boiler parts are cleaned and the boiler

efficiency is checked. A properly maintained boiler

running at optimum efficiency ensures ongoing energy

savings are maintained.

8

Contents


5. Keeping your Warranty Valid – Many boiler warranties

are valid subject to having an annual service carried

out. For many boiler manufacturers, failing to service

your boiler using an appropriately certified heating

engineer can invalidate your warranty altogether,

leaving you liable for costly repair bills.

6. Cheaper than Replacing a Boiler – If your boiler is

left faulty for long periods of time, much larger and

more complicated issues can arise, perhaps even

resulting in your boiler needing replacing. Recognising

any problems early on can reduce the amount of

permanent damage caused to your boiler and keep it

running for longer.

Commissioning

Once a system is engineered and installed, essential

checks should be made to ensure maximum safety from

the very start. The Automatic Heating commissioning

service involves checking that your systems have been

installed correctly as specified and includes various

testing procedures to ensure satisfactory performance and

compliance with appropriate regulations.

The commissioning process is the most important part

of any installation before it is set into full operation. In

addition, the Automatic Heating team can also program your

system, set it up and, where required, train your operator.

On Site Inspection and Audit

Where needed, we can organise one of our experts to

perform an on site inspection and audit. This will provide

you with a report on our findings and a recommendation on

which step to make next, whether it be maintenance, repair

or replacement of your equipment.

Repairs

Qualified Technicians

It is important that whoever services your boiler is suitably

qualified, experienced and equipped with the parts needed

to complete the service. This minimises costs and downtime

and ensures warranties remain valid. Automatic Heating

technicians are fully trained and qualified to service our

equipment and their fully stocked vans carry the parts

needed to complete each job.

Their professional competence and high level of practical

and diagnostic experience means you can be assured your

products are always running at optimum performance

when maintained by the Automatic Heating Service Team.

Support anytime, anywhere

Our service technicians are available for emergency callouts

and frequently provide support to clients in remote

areas.

From our Melbourne Head Office, our Operation and

Maintenance Department uses state of the art technology to

remotely monitor our O&M sites - as well as offering email,

SMS and mobile notification to ensure online operation for

your total peace of mind.

The Automatic Heating Service team is available to repair

your system even outside of the warranty period.

Our highly responsive technicians are trained in all areas

and applications of the most technical of systems with the

ability to quickly diagnose and fix problems on site, in most

situations. We understand every minute of downtime is a

cost to a business which is why we do everything possible

to provide a solution, even if it is an interim measure to get

your system back up and running as quickly as possible.

Parts & Consumables

We maintain an extensive range of genuine spare parts for

all commercial boilers, cooling systems, water heaters and

pressurisation units, to ensure our technicians can respond

quickly to our client’s servicing needs.

Your spare parts from Automatic Heating have quality

assurance conformity and carry a 12 month warranty. Using

genuine parts means you benefit from any technological

improvements that may have been made as part of our

policy of continuous product improvement. We are always

looking to make our commercial heating, cooling and hot

water products even more efficient.

HEAT PUMPS

Air to Water Heat Pumps offer unrivaled efficiencies of up to 350%.

Air to Water Heat Pumps can provide efficient heating and cooling for your home or

commercial building, especially if you live in a warm to moderate climate. An air to water

heat pump can deliver from 1.5 to 3 times more thermal energy to a building than the

electricity it uses. This can happen due to the fact that the heat pump transfers heat, rather

than transforming it from a type of fuel like regular combustion heating systems do.

Revere CO 2 - Air to Water Heat Pumps

Revere CO 2


A Sustainable Technology

Regardless of political agendas or incentives, consumers worldwide are

increasingly pursuing sustainable, cost effective alternatives to traditional fossil

fuelled equipment for their hot water and space heating requirements. Using

natural CO 2

as the refrigerant and achieving a high coefficient of performance

(COP), CO₂ heat pumps offer both ecological and financial benefits.

Contents

The unique capacity of the Revere CO 2

Heat Pump to

produce 90°C hot water makes it suitable for use in a wide

range of industrial, commercial and residential projects,

including food processing plants, dairies, shopping centres,

apartments, hotels, restaurants, hospitals, aged care,

recreational and educational facilities. Revere can also

be adopted with a high level of safety as the absence of

combustion reduces the risk of fire.

Instead of the more conventional ammonia or haloalkane

(R134A) refrigerant gases, Revere CO 2

Heat Pumps use

supercritical carbon dioxide as the refrigerant.

The technology offers a means of energy conservation and

reduces the emission of greenhouse gas.

From the energy output side, the operational characteristics

of the heat pump are different to conventional systems

(such as electric/gas/oil boilers or electric heaters). With

conventional systems, 1kW input of energy provides less

than 1 kW of output energy or heat. With a CO 2

heat pump

system, every 1kW of input energy consumed produces

an average of 3.9 x the input as output energy or heat by

extracting heat from the outside air.

Summary

Producing 90°C hot water with an average COP of 3.9,

makes Revere CO₂ Heat Pumps an ideal energy efficient

domestic hot water and space heating system for industrial,

commercial and residential applications. This ability to

convert 1kW of input energy into 3.9kW of output energy

represents an ongoing economical and sustainable water

heating solution.

Eco friendly - The Revere CO 2

Heat Pump uses natural

CO₂ refrigerant. This refrigerant has a global warming

potential (GWP) of about 1/1700 that of R410 and zero

ozone-depleting potential (ODP).

Energy efficient - Under optimal conditions, Revere

CO 2

Heat Pumps achieve an exceptional coefficient of

performance (up to 4.2) which equates to higher energy

efficiency. Compared to the traditional electric hot water

heater, the CO 2

hot water heat pump can save up to 75%

heating energy. Further energy cost savings can be

achieved through operation during off peak hours, subject

to off-peak electrical power supply.

Anti-freeze/Cold Area Units - the heat pump is fitted with a

defrost solenoid valve which will open when the evaporator

ices up. The hot gas will then flow through the evaporator

and melts the ice. Water cannot be stored during defrosting.

One pass heating - It is suitable for heating water from low

to high temperatures (large temperature difference) in one

pass.

Reduces storage requirements - Since this hot water heat

pump can heat water up to 90ºC, the size of the storage tank

can be reduced.

How It Works

The Revere CO 2

Hot water heat pump is an energy efficient electric heat pump that uses heat extracted

from the air to heat water for industrial, commercial and residential applications. A hot water heat pump

removes energy from a low temperature source (ambient air or waste water) and moves it to a high

temperature hot water tank.

Advantages of using CO 2

as a refrigerant

This heat pump uses CO₂ as a refrigerant. CO₂ is a natural refrigerant and has an ozone depletion

potential (ODP) of zero and a global warming potential (GWP) of 1. CO 2

refrigerant is a non HFC

refrigerant. Traditional HFC refrigeration systems affect climate change in two distinct ways: direct and

indirect contribution. Direct contribution results from the release of refrigerants into the atmosphere.

Indirect contribution refers to the energy used to operate traditional refrigeration equipment. The less

energy required to operate the equipment, the lower the impact on the environment.

Designed for Space and Energy Efficiency

With a heating performance of 80 kW, the

CHP-080Y2 was developed to reduce high

hot water supply costs and large space

requirements that inevitably occur in facilities

requiring a large hot water supply.

The structure of the Y-shaped frame reduces

power consumption and allows units to

be installed close together. The heating

performance can be switched between three

modes in order to adjust the energy to suit

how you use hot water, and performance does

not decrease* in temperatures down to -15°C.

This flexible system is suitable for a wide

range of facilities that use large volumes of

hot water, and is durable enough to provide a

steady hot water supply for a long time.

units run at a lower frequency, and the temperature control

accuracy can be as precise as 0.5ºC.

Energy Saving up to 30%

With the use of inverter compressors, brushless DC fan

motors and PFC control method, the units can regulate

the running capacity. With no frequent start-ups and stop

runnings, the units work in stable condition with high

efficiency. The energy consumption is 30% less than that of

common fixed speed heat pump units.

Intelligent Defrosting

Traditional Defrosting Method

Traditional defrosting method is with fixed defrosting time and

start temperature. Once the ambient temperature reaches or

is lower than -7ºC, the unit will start defrosting. This can lead

to energy wastage when defrosting is not needed and reduced

heating performance.

Intelligent Defrosting Method

The AHGR410AW series intelligent defrosting uses the

pressure sliding defrosting technology to figure out the exact

defrosting time and start pressure according to the real

ambient temperature. It saves energy and makes the heat

pump work in high efficiency.

Galleti MPI DC - Air to Water Heat Pumps

Galletti MPI DC

Air to Water Chillers & Heat Pumps 8 - 29 kW

Outdoor Packaged Unit with BLDC Compressor

Contents

Large operating range and energy efficiency

under every condition.

The MPI DC series consists of 6 heat pump models and 5

cold only models and is intended mainly for residential or

light commercial applications. Due to the control managed

by a software program developed by Galletti, the MPI

DC series’ adjustment logic makes it possible to adjust

the water delivery temperature to the set value and to

control the compressor so that the power generated by the

machine is adjusted to the thermal load required by the

system. This represents a strategic feature in the limiting of

energy consumption, because the effective thermal load of

an air conditioning system is less than 60% of the nominal

load most of the time.

The BLDC technology upon which is based the compressor’s

electric motor guarantees the ability to change the rotation

speed in a frequency range between 30 and 120 Hz, thereby

reducing at the same time the power consumption and

thus maintaining a high level of efficiency in the operation

at partial load and improved isentropic efficiency. These

units’ large operating range, which is also achieved due

to the variable flow water circulator they are equipped

with as a standard feature, guarantees operation with air

temperatures from -15 °C up to 52 °C, while in heating

mode it is possible to produce hot water up to 58 °C. This

allows their use as a single generator in addition to summer

air conditioning, even in medium-temperature heating

systems and for the production of DHW. Furthermore, the

innovative Smart Defrost System guarantees that defrosting

always occurs in the most efficient manner even under the

most extreme environmental conditions.

Advantages

• Twin-rotary or scroll compressor driven by an electronic

control BLDC motor

• Electronically controlled electric expansion valve

• Modulating hydraulic pump with stainless steel impeller

• Optional internal buffer tank

MPI DC can be the only heat generator in low-power systems

due to its large operating range that includes both low winter

temperatures and high summer temperatures.

Main Components

• Structure

It is constructed of galvanized and painted sheet metal that

is resistant to corrosive agents. Compressor compartment

closed and accessible from three sides due to easily

removable panels, available also with internal coating of

soundproofing material.

• Compressor

Hermetic twin-rotary or scroll compressor driven by

a permanent magnet BLDC motor and controlled by a

trapezoidal wave inverter. It is attached to the base by

means of rubber dampers to reduce the transmission of

vibrations.

• Heat exchanger

Finned heat exchanger constructed with copper pipes

mechanically attached to aluminium fins, carefully designed

to minimize the defrosting phases and optimize heat

exchange efficiency in every operating phase.


• Electronically controlled electric expansion valve

Key component for the proper functioning of the unit.

The PID control algorithm allows it to quickly adapt to all

operating conditions and to keep the cooling cycle stable.

• Hydraulic Kit

Variable flow centrifugal circulator with stainless steel

impeller. An expansion vessel and the automatic filling

tap are also included. An inertial buffer tank built into the

structure is available as an optional accessory.

• DHW Kit

A system that makes it possible to transform the MPI

DC heat pumps into multi-purpose units that are able

not only to meet the requirements of the air conditioning

system, but also to produce domestic hot water as a

priority by means of the Galletti TP or TN series thermal

storage tanks. It is comprised of a microprocessor

control unit with LCD display and a 3-way motorized

valve. Also, anti-Legionnaire’s disease cycles can be

activated by means of a heating element.

Galleti MPE - Air to Water Heat Pumps

Galletti MPE


Outdoor Packaged Unit

Contents

Efficiency under all operating conditions.

MPE water chillers and heat pumps are designed for

outdoor installation in both residential and industrial

applications. The range uses R410A refrigerant, which

assures high levels of performance with relatively low

energy consumption and features 25 models in the chiller

and heat pump version, with cooling capacities ranging

from 4 to 76 kW and heating capacities from 5 to 85 kW.

The finned block heat exchangers have been optimised

for R410A and use 8 mm copper pipes, which permit a

better heat exchange and quiet operation of the fans. Their

generous sizing guarantees the production of chilled water

even with outdoor air temperatures as high as 51°C.

In the MPET models, with a double compressor on the

same cooling circuit, the working temperature range is

extended further and efficiency at partial loads increases.

In demanding working conditions the microprocessor

controller activates the capacity control mode, doubling the

condensing surface available to the single compressor.

The self-adaptive logic allows the setpoint to be adjusted

automatically according to the outdoor temperature in

order to reduce consumption and broaden the working

temperature range.

The unit can also function in systems with a low water

content, even without the use of a water buffer tank, thanks

to the automatic adjustment which limits the number

of compressor starts and thus extends the life of the

compressors themselves.

The exclusive Smart Defrost System (optional feature

available with the advanced controller) can correctly

identify an impairment of performance in the outdoor

exchanger due to the formation of ice and minimise the

process time in relation to normal operation of the unit.

Advantages

• Completely configurable range

• Dual-compressor version that guarantees high efficiency

at partial loads

• Production of chilled water up to an air temperature of 51ºC

• Built-in hydronic unit

MPE heat pumps and water chillers are designed for heating

or cooling the water to be used in air-conditioning systems for

residential or commercial use.

Main Components

• Structure

Painted galvanised sheet steel structure (RAL9002) for an

attractive look and effective resistance to corrosive agents.

Fastening devices are made of non-oxidizable carbon steel

that has undergone surface-passivating treatments.

• Customised hydraulic kit

The structure can accommodate hydronic kits with pump,

expansion tank, and buffer tank. High head pump made

entirely of stainless steel, already configured for use

with mixtures of water and ethylene glycol up to 35% and

provided with internal thermal protection.

• Fan drive assembly

Electric fan with external rotor motor directly keyed to the

axial fan, with internal thermal protection on the windings.


• Finned block heat exchanger

Made of 8mm diameter copper pipes and aluminium fins.

The heat exchangers’ particular design makes it possible to

speed up to the maximum the defrost phases in the versions

with heat pump with obvious benefits to seasonal efficiency

while operating in heating mode.

• Electronic microprocessor controller

The electronic controller enables the complete control of the

MPE unit. It can be easily accessed through a polycarbonate

flap with IP65 protection rating. It implements the

compressor regulation logic and allows the complete

management of the unit’s other parts, the reversal of the

cooling cycle, and the alarms.

Units Optimised for

The Scroll compressors of the

HPS range relies on the vapour

injection technology: a small flow

of refrigerant in the vapour state

at medium pressure is “injected”

in the scrolls into the compression

chamber. This system allows an

increase both of cooling capacity

(thus heating capacity) and of

efficiency and, above all, an extension

of the working range of the heat

pump, which makes the HPS range

the ideal solution in case of very cold

outdoor conditions.

Extremely Low-Noise

All the units in the HPS range are supplied in the “Low

Noise” version as standard equipment; this version features

fan speed management, anti-vibration piping on the

refrigerating circuit, compartment of the compressors and

of the pumping kit in a box with soundproof material: this to

guarantee the lowest sound emission at all working points.

Smart Defrost System

The defrosting cycle of the evaporating coil during the

wintertime has a significant impact on the operating costs

of the entire system. The Smart Defrost System® by HiRef

(covered by patent) can detect a performance drop in the

heat exchange due to icing and to shorten the defrost

time. The hydrophilic treatment of the coils speeds up the

defrosting process, so that only the first thin layer of ice on

the fins needs to melt.

Efficiency and Reliability

According to the Installation Needs

The available configurations for the refrigerating circuit

are designed to guarantee both redundancy and efficiency

at partial loads. In particular, depending on the size of the

machine and on the particular needs of the installation,

the units consist of two compressors on two circuits for

high system redundancy, or by four compressors (double

tandem) on two circuits for a system that is, at the same

time, redundant and efficient at partial loads.

Galleti EvitecH - Air to Water Heat Pumps

Galletti EvitecH

Contents

Air Heat Pumps with wide working range 50 - 180 kW


Reliability and efficiency

in every climatic condition.

EvitecH is Galletti’s new high efficiency multiscroll units

equipped with R4 l 0A steam injection compressor. The

range consists of 10 air-water models available as chiller

and heat pump, with cooling capacities from 50 to 180 kW.

The main strong point of this series is the large operating

field, both in terms of maximum hot water temperature

(65°C with -11 °C of external air temperature) and minimum

air temperature at which the continuous operation is

allowed (-20°C)

The range allows high configurability from an acoustic

point of view, having a wide range of accessories de signed

to reduce noise emissions. The advanced control, always

present in the whole range, allows a continuous monitoring

of the operating parameters, advanced ad justment logics,

and connectivity.

The modular structure with V configuration condens ing

coils is designed to optimize air-side heat exchange, to

ensure structural strength with a reduced footprint, and to

maintain maximum accessibility to the basic components.

In addition to high efficiency in terms of nominal condi tions

(Eurovent A-class), in order to increase the efficien cy at

partial loads, the whole range consists of tandem solutions

(2 compressors on a single refrigerant circuit). The

configuration of units with the Hydro Smart Flow kit allows

an increase of the efficiency and extends the working area

of the cooling mode.

Advantages

• Class A in heat pump operating mode

• Production of hot water up to 65°C

• Full load operation up to -20°C outside air temperature

• High efficiency under part load conditions

• Possibility to configure low-noise versions

• Counterflow solutions in every operating mode

EvitecH heat pumps are designed

for heating or cooling the water to

be used in air-conditioning systems

for residential, commercial or

industrial use.

The execution with injection steam

com pressors (EVI) guarantees the

production of hot water at high

temperatures even in very harsh

outdoor conditions (outdoor air

temperature down to -20°C).

Main Components

• Structure

The range, starting from size 72, is designed modularly, replicating

the optimized structure ofV configura tion condensing coils and

fans. Its design ensures stability and sturdiness even during

the most critical phas es (such as transportation), and maximum

accessibility to compo nents in every unit.

• Hydro smart flow

The HSF kit (standard for models 52 and 62) is placed on the

unit’s hydronic side and consists of a 4-way valve and a kit. Hydro

Smart Flow, which is activated at the time of seasonal changeover,

reverses the direction of the water fiow over the plates to be

consistent with the fiow of the refrigerant. In this manner heat

exchange always occurs in counterfiow, thus optimizing the unit’s

operation in the summer and winter seasons and extending the

unit’s operating range.

• Upwind

EvitecH is designed with an inno vative technology which allows the

refrigerant to get into the battery from the same direction when the

cycle is inverted, with a constant counter-current exchange with

air. This advanced technology considerably reduces the risk of ice

generation on the finned heat exchangers.

• Scroll compressors with vapour injection

The range consists of single and dual-circuit models in order to

offer maximum redundancy. The distribution of load in multiple

power steps and the use of tandem solutions (2 compressors

on a single circuit) ensures maximum efficiency at partial loads

and therefore greatly increases seasonal efficiency. lntercooled

compression with steam injection allows a better control of the

end-compression temperature, keeping it within the limits imposed

by the compressor envelope, even in the most unfavorable working

conditions (low evaporation pressures and high compression

pressures), this results in one of the largest operating field in the

market.

• 3-Way valve

This is a smart kit able to convert EvitecH heat pumps in multifunction

units in order to fulfill every necessity of the hydraulic airconditioning

plant. It allows domestic hot water priority production

thanks to Galletti thermal accumulators of the TP or TN series. The

switching of the valve is managed by the on-board microprocessor

control of the unit.

Galleti SCX - Air to Water Heat Pumps

Galletti SCX



Contents

High configurability and efficiency at partial loads.

SCX is the new series of air-cooled heat pumps and

chillers designed to meet the requirements of efficiency,

configurability, reliability, and ease of maintenance.

The series comprises 22 models with cooling capacities

ranging from 80 to 360 kW. They are available both in

models with a cooling function only and in models with heat

pump operation.

The finned block heat exchanger is generously sized to

optimize operation as both evaporator and condenser by

type of fin and circuit.

The solution of a single heat exchanger with delivered

power of up to 160 kW was adopted due to the complete

accessibility to the internal water and cooling circuit for

the periodic inspection and maintenance operations. The

solution of a single heat exchanger makes it possible to

reduce the space necessary for the installation of the units.

The electric axial fans with blades with an exclusive

aerodynamic profile (HyBlade®) are characterized by

extraordinary aeraulic and acoustic performance and

represent the current state of the art for axial fans.

The AxiTop® diffuser allows fan efficiency to be further

increased with benefits in terms of noise level (together

with condensation control) and unit efficiency.

The SCX design adopts innovative solutions in the use and

arrangement of the hydronic kit’s internal components,

which is simplified to reduce the number of connections

and minimize the water side head loss inside the machine.

Every model is completely configurable with a choice of

control, hydraulic, acoustic, and heat recovery options that

do not result in any change to the dimensions.

Advantages

• Completely configurable range

• Incorporable hydronic kits

• HyBlade® fans

• Tandem and trio solutions for high efficiency at partial loads

• Remote connectivity with the most common protocols

The choice to install scroll compressors in a tandem or trio

configuration on the same cooling circuit is a move in the right

direction in terms of machine efficiency at partial loads, which is

the normal operating condition for air conditioning systems.

Main Components

• Structure

Made in galvanised steel sheet with a polyester powder coating for

outdoors. Base with reinforcement modules for eliminating any

deformities resulting from impacts sustained in the transportation

and handling phase.

• Scroll compressors

Scroll type compressors in a tandem or trio configuration that can

be sound insulated. The adopted components’ efficiency, reliability,

and noise emission levels represent the state of the art for scroll

compressors.

• Electronic microprocessor controller

In standard or advanced version, it enables the complete control

of the units. It can be easily accessed through a polycarbonate

flap with IP 65 protection rating. The electronic control system

allows the setpoint to be adjusted automatically according to the

outdoor temperature in order to reduce consumption and broaden

Configuration

The models are completely configurable by selecting the version

and the options. An example of configuration is shown below.

Condensing Boilers offer several significant advantages:

• Lower emissions

• Reduced fuel usage

• Justified return on investment

The “Greener” boiler technology utilised in condensing systems utilises the latent heat in flue gases

which can lead to gross operating efficiencies of up to 98%. By using Condensing Technology, operating

costs can be reduced by 15-20% resulting in substantial long term running cost savings.

Introduction to

Condensing Boilers

Condensing water heaters have been manufactured since the 1980s, and now

represent a fully mature technology used extensively throughout the world.

What is a Condensing Boiler?

The condensing water heater is a system of technologies,

consisting of the water heater itself fuelled by gas or

oil, the flue stack, and the condensate collection system.

Condensing water heaters operate at around 90-98% gross

efficiency, compared with 80-85% gross efficiency for

conventional water heaters.

They achieve higher efficiencies by using newer technology

and by condensing the water vapour that is produced during

combustion and trapped in the flue gases.

In traditional water heater technologies, the latent heat

contained in the water vapour is allowed to escape through

the flue. Condensing water heaters reclaim that latent heat

by condensing the water vapour and transferring its heat

to the return water via a secondary heat exchanger with a

resultant increase in water heating efficiency.

The flue stack temperature is considerably

reduced and the return water temperature

raised. Hence the term ‘Condensing Water

Heater’.

These potential efficiency gains are achieved if the water

heater is operating in or near condensing mode, which

requires the temperature of the water returning from the

building to the water heater to be as low as possible. Having

said that, condensing water heaters will achieve increased

efficiencies over non-condensing water heaters even in

a situation utilizing the existing building return water

temperature, due to the larger surface area of the heat

exchanger in a condensing water heater and the reduced

flue temperature.

Optimum return water temperatures are achieved when

the return water is below the dew point of the water vapour

in the flue gas. The dew point is determined by several

variables, including altitude, outdoor air temperature, and

the type of fuel the water heater consumes. The critical

variable, however, is combustion efficiency: excess oxygen

in the combustion process leads to lower efficiency and

requires a lower dew point before condensation can

begin. In general, with efficient combustion, return water

temperatures (RWT) should be below 54°C, with lower RWT

resulting in more condensation and greater efficiency.

Condensing water heaters require Stainless Steel flues to

prevent corrosion. The condensate produced is also slightly

acidic so a condensate neutraliser is required before piping

condensate to the drain. Plastic piping must be used for the

condensate drain to prevent corrosion.

Why is a condensing boiler “greener” than a

non-condensing one?

A condensing boiler makes better use of the heat that

it generates from burning fuels such as gas or oil. In a

conventional boiler some of this heat is wasted because

the boiler releases very hot waste gases from its flue. A

condensing boiler uses some of the heat from these waste

gases to heat water returning from your central heating

system, so it requires less heat from the burner. This makes

your condensing boiler more efficient. The efficiency of a

boiler is normally expressed as a percentage – some new

condensing boilers can be up to 98% efficient compared to

non-condensing ones that are around 80 to 83% efficient,

and older boilers that are only 70% to 75% efficient.

How does a condensing boiler reduce carbon

dioxide emissions?

RETURN WATER TEMPERATURE ºC

Carbon dioxide savings come from burning less fuel to

meet your heating needs. Imagine that one unit of fuel

potentially contains enough energy to heat your home for

an hour. Burning that fuel in a boiler that is 100% efficient

would heat your home for an hour. Burning that unit of fuel

in a boiler that is 90% efficient would only give you enough

to heat your home for 54 minutes, and if it’s 75% efficient

you’d only get 45 minutes per unit. So, the lower the

efficiency of your boiler the more units of fuel you need to

burn to keep your home at the right temperature. The more

fuel you burn, the more carbon dioxide you emit.

Condensing Boilers

How does a condensing boiler work?

Like conventional boilers, a condensing boiler burns fuel

to heat the water in a metal heat exchanger. A condensing

boiler uses an extra-large heat exchanger (or sometimes

two) to maximize heat transfer from the burner and recover

useful heat from the flue gases. In condensing mode the

flue gases give up their latent heat and can exit the flue in a

visible plume of water vapour at 70-90°C – they’re usually

180-200°C in a non-condensing boiler. At the same time

condensate, is produced which must be drained away.

Are they only efficient when in

condensing mode?

A condensing boiler is always more efficient than a

conventional non-condensing boiler, due to its larger and

more efficient heat exchanger. The rating represents the

average annual efficiency the boiler can achieve in typical

conditions, making reasonable assumptions about how

it’s used, the climate, controls, and other influences. This

indicates how efficient your boiler will be taking into account

its efficiency in condensing and non condensing mode.

Is it worth changing a five-year-old

conventional boiler for a new

condensing one?

Gas prices are rising, so efficiency is crucial. To comply

with new building regulations, new or replacement boilers

must have an energy gross efficiency of at least 90%.

Condensing Boiler Vapour Plume

They produce a visible plume of vapour when they are

operating, so the flue terminal needs to be sited carefully to

avoid the steam creating a nuisance.

They produce an acidic condensate that must be passed

through a condensate neutraliser and plumbed into a

suitable drain.

Features

• High efficiency condensing boiler ≤ 109% Nett. Exceptional

heat transfer is achieved via the patented multi radial flue

gas fins. Eurogen also incorporates 100 mm heat insulation

to minimise radiation losses.

• Balanced combustion chamber geometry for rapid heat

transmission and clean and complete combustion.

• Dual fuel burner configurations are available

• Compact footprint and versatile design - three pass flue

gas exhausts in two cylindrically arranged, stacked boiler

drums. The 860mm boiler width (up to EG570) allows ease

of plant room access and installation and the door can be

hinged as right or left handed.

• Large water volume provides good thermal stratification

and allows the system to operate with just one primary

pump, thereby reducing power usage.

• Variable water flow allows varying of the water flow rate

to match the combustion rate of the burner. As the burner

modulates from high fire to low fire, the water flow can

be varied from high to low. This maintains a constant ΔT

through the boiler. Whether 20° or 30° ΔT is required, this

can be maintained through all phases of combustion by

varying the water flow to match the burner modulation. This

maximises the amount of heat extracted from the flue gases

and thereby increases efficiency.

Advantages

• Fully Stainless Steel - All parts of the Eurogen Condensing

Boiler that come in contact with flue gas or condensate

are made from stainless steel. This feature ensures the

longevity of the boiler through resistance to corrosion from

the acidic condensate created inside the boiler.

• Certified Efficiency - The Eurogen Condensing Boiler is

manufactured in Italy and is professionally designed and

built to perform to specification. Certified test results

from a reputable laboratory are available prove its stated

efficiency.

• No return water temperature limitation - Eurogen

accommodates lower return water temperatures and can

operate at a ΔT of up to 30°C.

connections to keep return water temperatures as low as

possible to maximise condensing benefit. Together with very

low standby and flue losses, net efficiencies of up to 107%

can be achieved. Two return water connections are available

allowing the differentiation of high or low temperature return

water to create the optimum efficiency result depending on

the application.

Modulex EXT

Condensing Boiler 150 – 1200kW

Modulex EXT is a new range of floorstanding

condensing boilers that

provides an infinitely flexible solution

for buildings requiring a high output

heating system.

There are eight floor-standing boilers to choose from,

with outputs ranging from 150kW to 1200kW. Each

one is made up of a number of self-contained heat

generating modules forming what is, in essence,

a series of boilers linked together within a single

casing. This modular design enables Modulex EXT

boilers to optimise energy efficiency and comfort

levels for building occupiers like no other boilers

available today.

Each linked module shares a single set of ancillary

components including flow and return pipes,

electronic controls and flue. This greatly eases the

installation process and, along with the internal easy

access layout of each boiler, simplifies servicing.

Compact overall dimensions and ultra-low operating

noise levels gives the system designer greater

flexibility when it comes to positioning the boiler

within the building. With a host of benefits for the

consultant, contractor, client and building occupier,

Modulex EXT boilers provide the perfect heating

solution for a wide range of projects from hotels to

office buildings, schools to sports centres.

Each heat generating module within our Modulex EXT

boilers is self-contained, with its own downfiring premix

gas burner, fan, ignition and safety controls. As

system load decreases, a built-in Boiler Cascade Manager

modulates the boiler down to the combined minimum. As

loads continue to reduce, individual modules are switched

off as necessary down to a minimum output of a single

module – 12kW for 150-350kW models and 22kW for 440-

1200kW models. This ensures optimum load matching

and minimises wasteful boiler cycling, maximising energy

efficiency in the process. The combination of a high

modulation ratio up to 1:54 and a high output plus very low

water content ensures rapid warm-up and turn-down times

for Modulex EXT boilers. They are subsequently also able to

respond quickly to changing demands throughout the day.

Thanks to their modular design, Modulex EXT boilers will

continue to operate even in the unlikely event that a single

module malfunctions.

Features

• Exceptional energy efficiency

(up to 109% at the minimum modulated capacity)

• Low noise

• Ultra low emissions

• Full BMS capability.

Allows monitoring of performance and faults

• Variable Water Flow rate - Allows the boiler to operate at a

constant 20°ΔT – maintaining the boiler at the most efficient

duty point.

• Able to be supplied as dismantled - When needing to achieve

installation in tight plant rooms or inaccessible areas, this

feature can enable much better access and often saves

significant costs involved in placing equipment via a crane

from outside the building.

Advantages

• High turndown ratio of up to 1:54 - This provides significant

energy savings, particularly for part load or low load

requirements. It also stops boiler cycling and contributes to

its very quiet operation.

• Multi burner construction - If one burner requires

maintenance, the other burners can continue to operate,

providing built-in redundancy.

• Small space saving footprint - This makes it easy to install

in plant rooms where floor space is at a premium.

kW for the models up to 350 kW, and from 22 up to 108 kW

for larger models.

More than 10 years experience assure:

• Resistance to the corrosion of the acidic condensate

• Very high thermal efficiency

The basic element is formed by two aluminium alloy

castings that, on the smoke side, have dense fins, with

increasing height toward the smoke discharge, placed in

lower part of the casting, in order to increase its exchange

surface.

Inside the castings there are the water channels that zigzag

cross the casting, granting an exceptional heat transfer

from combustion gases to the water.

Every thermal element is equipped with:

• Premix modulating burner

• Two stage modulating gas valve

• Electronic ignition and ionization

• NTC working temperature sensor

• Safety thermostats

• Flame sight glass

The smoke and acidic condensate of the thermal elements

are collected in a stainless steel tray.

The MODULEX EXT

exceeded all industry

requirements when it

was first conceived over

a decade ago. These days

the high standards and

benchmark qualities of this

groundbreaking heater are

a must in today’s world.

Setting option according to the

thermal needs of the C.H. system

This function enables you to

drastically reduce the number of

switching ON and OFF of the heater

(Possible customization of the

requested output)

Advantages:

• Higher efficiency and lower flue

losses when burner is OFF

• Longer lasting of the parts in

movement and of the ignition

systems

Very low water content and high

modulation speed with maximum

output ratio up to 1:54

On average a heater operates at

50% of the thermal need of the C.H.

installation and can descend below

30%. MODULEX EXT adjusts in real

time the output to meet demand,

because it is not influenced by the

thermal inertia, thanks to its low

water content and, being equipped

with modulating pump, it further

reduces the electricity used.

Class A, variable speed, electronic

pumps, for the maximum

condensate production

This function promotes the

production of condensate and

therefore the fast economic recovery

of the investment. All this in order to

offer the user the possibility to save

with the maximum comfort both, for

C.H. and D.H.W. production, with a

lower noise level than the traditional

boilers

MODULEX EXT is at 50% of the load, while the traditional one is at 30%. After the time “T3”

MODULEX EXT has a certified

efficiency that, for all models

above 350 kW, when working in

condensation, progressively increase

up to 109% when the output is

reduced.

The genius of the thermo-controller

E8 is that it keeps ON the greatest

number of elements as possible,

working at the smallest possible

output (as shown in the examples

beside).

The system will always work in the

conditions of maximum possible

efficiency, independently from the

supplied output.

When the requested output is less

than the capacity available the design

of the Modulex regulates evenly

reducing the output of each module

to suit. Once the minimum level for

a module is reached it is disabled in

cascade sequence.

This modular system is such that

as the number of modules used

decreases - the efficiency increases.

The flexibility of this modular

conception is ground breaking and

brings vast cost savings through

increased efficiency.

To avoid one element module being

over used more than others, the

thermo-controller automatically

alternates usage of all element

modules evenly.

With the cascade installation, the

boiler output range can be widened

to well in excess of 1200kW,

multiplying output and modulation in

order to satisfy any design demand.

The space saving (in particular the

boilers can be installed up to 40cm

from the boiler house walls) features

of the Modulex Boiler are tailored

specifically with service and easy

access in mind. Replacement of

old obsolete boilers is also another

benefit that a small foot print allows.

Moorea I

Condensing Boilers

125 – 610kW

The new floor standing condensing gas

boiler, Moorea I, represents the highest

evolution stage within the middle output

range of gas fired condensing boilers.

The continuous development of floor standing

condensing boilers has identified a smaller foot print,

improved modulation range and reduced operating

noise as key product features. Moorea I is improved in

all three areas.

Available in eight outputs; 170, 215, 260, 300, 400,

470, 540 and 610kW, the Moorea I is designed with the

customer, installer and specifier in mind. Using the

very latest heating technology with a heat exchanger

made from aluminium/silicon with a 10 year warranty*

and a combustion system which delivers exceptional

energy efficiency as well as advanced ultra low NOx

performance of 35mg/kWh (Class 5).

Conventional Boilers

The use of boilers is the most common form of central heating and

process heating throughout the world.

Forced draft boilers use a circular drum that allows the combustion of gas or oil which then exits

through tubes surrounded by water - transferring the heat. Atmospheric heaters use natural

draft to combust fuel by mixing the gas and air in a venturi. This then heats a cast iron or copper

tube filled with flowing water.

Arizona

Conventional Steel Boilers

Standard and High Efficiency HR 150 – 3500kW

Arizona is a range of pressurised steel boilers suitable for use with

forced draft air burners running on diesel or gas. The Full Mild Steel

scotch marine construction unit comes equipped with fully modulating

power dual fuel or gas burner.

Note: control panel shown for illustrative purposes only and may not be used on actual boiler.

High efficiency HR Range

The Arizona High Efficiency HR range have an increased

efficiency of 5.0 % from the standard Arizona unit. They

feature special turbulators which increase the heating

surface of the boiler. These three pass wet back design

Arizona HR Boilers have the furnace back plate which is

continually cooled from the return water ensuring the most

amount of efficiency is reached on every application.

Arizona HR boilers are ideal for applications where

improved efficiency is a criteria without the need to

progress to a condensing boiler. The HR range sit

between standard boilers and condensing boilers in

operating efficiency.

Features and Advantages

Three Pass Performance - The Arizona is a high output

boiler made entirely of carbon steel to allow it to operate

at different powers within a set range. Arizona is a scotch

marine boiler featuring three combustion gas passes. The

cylindrical combustion chamber has a wet back, which

improves heat exchange between the combustion gases

and the water. The front door is lined with specially shaped

firebrick to make it easier for the combustion gas to enter

the tubes. The combustion gas passes through the tubes at

very high speed and turbulence, and into the rear smoke

chamber. The turbulence is accentuated by specially

designed turbofans that help increase heat exchange.

Anti Condensation - An exclusive system has been

implemented to prevent the formation of condensation.

The smoke tubes and turbo fins are specially designed

to guarantee a high and rapid heat exchange for the

combustible gases. The shape of the rear section of the

smoke tubes protects the welds by raising the temperature

in the area as far as possible.

Uniform Temperature Distribution - The internal panelling

has been designed to allow the water inside the boiler

to be distributed optimally and evenly, depending on the

temperature. This ensures maximum safety and reduces

scale deposits which reduce the surface area and make the

boiler less efficient.

Very Low Pressure Drop - The very low pressure drop

across the boilers allow for smaller primary pumps with

less head pressure required reducing the motor Kw’s

Australian Approved and Globally Recognised - All the

components are fully Australian approved and have proven

very successful in Europe and throughout the world.

Crane Lift Packages Available - Outdoor “crane-liftable”

versions available in all sizes.

CONDENSING &


High Water Content - The High water content is ideal for

large systems with long operating hours.

Expansion - The firebox of the Arizona boiler is designed to

expand to increase the elasticity of the entire structure and

enable it to withstand stress better.

XRE

Cast Iron Sectional Boilers

150 – 1450kW

Note: control panel shown for illustrative purposes only and may not be used on actual boiler.

XRE Cast Iron Sectional Boilers, being of modular construction, are ideal

for retrofitting into plant rooms with limited access as they are supplied

unassembled and can fit through a standard doorway. They are able to

be fitted with either oil, gas or Low NOx burners.

The XRE provides high energy output whilst offering

significant energy savings and reduced environmental

impact. It is ideally suited to underfloor heating

applications.

Exchange surface are arranged in parallel streams for

higher performance and the crossed girder construction

ensures excellent distribution of mechanical forces.

The large heat exchange surface in the combustion

chamber allows better and more efficient exchanger/

burner combinations. XRE boilers display high combustion

efficiency of up to 83% depending on configuration.

Increased insulation results in a remarkable reduction

in heat losses and energy consumption. Double layers of

100mm glass wool let the boiler operate efficiently and

quietly for your peace of mind.

The XRE has been designed for ease of installation and

problem free maintenance. Hinged door and reversible door

hatch provide easy access. For low temperature operation

modulated down to 40°C.

& Oil Burners

Continued investment in research and development ensures our burners

deliver optimised performance and minimum ecological impact.

Our burners can be equipped with the most modern automatic mechanical or electronic

modulation systems that maintain the correct gas/air ratio. In this way, the burner’s thermal load

is adapted with precision to the need for heat in every moment of operation in order to guarantee

optimised output at every point in combustion.

35 - 8,000kW

The Enterprise natural gas burners cover a firing range from 35kW to

10,000kW and are suitable for small, medium and large applications.

The Enterprise burners are designed to be aesthetic

and functional but at the same time gives prominence to

innovative technologies; in fact all components can be fitted

onto a backing plate which can be moved and attached

to special fixings within the burner to make maintenance

easier.

The models can be supplied for operations as follows:

• TN: On / Off

• PR: Progressive

• AB: High / Low

• MD: Modulating

Low NOx models

Enterprise gas burners are also available in Low NOx

models.

Our low NOx burners benefit from the installation of an

innovative combustion head that re-distributes the gaseous

element according to different weights and in a negative

pressure zone, which allows a portion of the combusted

gases to re-circulate

Enterprise burners feature a high performance combustion

head which ensures safety and increased efficiency. These

units also feature simplified maintenance through convenient

access to essential areas. A cam driven by the modulating

motor ensures a smooth transition from low to high fire.

Enterprise Dual Fuel Burners

35 - 13,000kW

The Enterprise dual fuel range are suitable

for use with either natural gas/LPG or

natural gas/light oil. This range of burners

cover a firing range from 35kW to 13,000kW.

These burners have been carefully designed to provide

maximum efficiency with either gas or light oil. Fuel change

over is achieved by the “flick of a switch” which prompts

the burner to carry out a controlled shutdown. The high

performance fuel pump is driven by a separate motor and

only operates when oil firing operation is selected.

The compact dimensions of these units greatly simplify

maintenance. They all feature an aluminium die cast

housing, an easily removed cover and a grill on the air

inlet to prevent foreign materials being drawn into the fan.

The combustion head is adjusted by means of a graduated

screw.

LMV Electronic Burner Control - Gas, Dual Fuel & Oil Burners

LMV Electronic Burner Control

CONDENSING &


Electronic Cam and Control System for medium and high power gas,

light oil, heavy oil and mixed fuel burners.

Automatic Heating, has adopted an electronic cam and

control system in its line of Enterprise burners.

This innovative system, which has been divided into two

types of flame control box, can be used for both commercial

(from 140 kW) and industrial applications (up to 70 MW).

Burners designed for use with a single or mixed fuel with

continuous or intermittent operation and permits the

command and control of all the various elements that plan a

part in the correct mixture of the fuel and combustion air by

means of an appropriately programmed flame control box.

This versatile solution oriented to the future permits the

achievement of the maximum precision in combustion

adjustment.

The system can also be expanded through interface with

an oxygen control probe and/or a fan speed adjustment

inverter in order to improve performance even further, in

this way obtaining the highest savings in energy in terms of

both the fuel and the electric power required.

The command and control system is composed of a

twin-microprocessor electronic unit for the integration

of all burner command and control functions, and a local

programming and adjustment unit.

Integrated functions include air/fuel ratio adjustment (with

work point configuration possibility), PID temperature or

pressure regulator, gas valve leakage control, adjustable

cycle times, pre-configured fuel trains and input/output

configuration.

The programming levels are protected by password for the

three types of user (manufacturer, servicing personnel, final

user); dialogue between the servocontrol and the sensors is

performed using twin-channel CAN Bus protocol in order to

guarantee the greatest safety and reliability, and the unit can

be installed directly in the machine or inside a separate electric

control panel positioned no further away than 100 meters.

Using the appropriate designated optional software the

system can be configured directly by PC.

All flue parts are to be assembled in a consistent

fume direction (as indicated by arrows)

Gaskets must be placed inside the female socket,

with the profiled face always pointing inwards

towards the centre, smooth side outwards

seated in the groove. Condensing Boilers - Black

Gaskets, Non Condensing Boilers - Red Gaskets

Using silicone spray on the male element, join

together gently ensuring gasket remains in

groove.

Fasten the locking band around the ridges of the

male and female joint, taking care to ensure that

the pointed arrow is fitted to match the direction

of flow. The locking band will only fit properly in

one direction.

Flue Dilution

CONDENSING &


Introduction to Flue Dilution

A flue dilution system is normally installed where there are difficulties in the provision of a conventional

flue, or indeed where savings can be made if the only other alternative is a high rise flue. Using flue

dilution, boiler fumes can be discharged from the side of a building including at low level.

How Does It Work?

The general principle is that ambient air from outside the building is mixed with the flue gas in order to

dilute the CO² content to less than 1% when using natural gas or LPG boilers.

As with all flue systems, local gas authority approval must also be sought for a flue dilution system.

The shift in the commercial market towards condensing boilers, has had a significant evolutionary

effect on flue dilution. The flue gas temperature from these appliances is far lower than traditional

atmospheric boilers, and as a result condensation is created within the flue. By mixing this warm moist

gas with cooler air, the mixed gas temperature is reduced further, creating more condensation. There are

a few critical considerations:

• Material of flue system – only use 316 grade stainless steel on condensing applications and flue dilution

systems.

• The flue system must be capable of handling condensation in large quantities.

• Pluming at the flue discharge – suspended water molecules in the diluted flue gas will be discharged out

through the grille to atmosphere. This pluming can often be significant and can cause a nuisance to local

residents and building occupants. Therefore careful consideration of the discharge position is of utmost

importance.

Draft Regulator - Flue Systems

Draft Regulators

Introduction to

Draft Regulators

For proper operation and efficient fuel consumption in gas,

oil & biomass heating boilers, draft must remain constant.

When it is, combustion is more complete, fuels are utilized

efficiently, and money is saved.

Draft Regulators maintain consistent draft by counteracting

the negative forces caused by changes in temperature and

barometric pressure, as well as the effects of wind.

How draft regulators work

Static pressure of the cool air (1) illustration A exerts

pressure on the outside of the furnace or boiler and the

stack. The pressure difference between the room air and

heated gas (air) causes products of combustion (2) to

flow (draft) through the unit and rise up the flue. Room

temperature air (3) enters through the barometric draft

control (4) in the precise amount needed to overcome the

excess drafts caused by temperature variations, wind

fluctuations, and barometric pressure changes. Combustion

of fuel is complete and the process is stabilized. The

velocity of combustion gases through the heat exchanger is

slowed so more heat is extracted. The unit operates more

efficiently, reliably, and requires less maintenance.

Biomass Heating systems offer an economical and enviro-friendly

option for heating generation.

Biomass Heating systems burn wood pellets or wood logs to provide warmth to power

central heating for domestic or commercial applications. They provide low carbon heat

due to the fact the carbon dioxide emitted when wood is burned is the same amount that

has been absorbed over the months and years that the plant was growing. The process is

sustainable as long as new plants continue to grow in place of those used for fuel.

The force of steel,

the heating energy of stone

Obtaining energy for heating in different ways is essential, not

only for the whole country, but also for each individual who

has the opportunity.

As part of Unical’s programme for exploiting biomass in

order to attain a major harmony with the environment, we

are pleased to present three new wood log boilers, ideal for

those consumers who, aware of the energy problems they are

facing, desire products easy to use, with high performances

and reduced fuel consumption, without having to resort to

onerous investments.

Simplicity and perfection

The range of FOKOLUS boilers sums up the most primitive

features which wood evokes. On one hand nature and on

the other the technology which Unical has been able to

develop. With the combustion process, the whole cycle which

characterizes renewable energies comes to a close.

The results are: comfort, economics, friendly environmental,

all offered “naturally” by FOKOLUS.

Features

Controlled combustion, long boiler operation

and reduced emissions

The optimization of combustion is guaranteed by the

thermostatic primary air inlet regulator and by the

micrometric secondary air regulator.

However, it is the use of a special refractory catalyst,

positioned in the combustion chamber’s upper vault, which

favours the pyrolysis process of the cellulose and the

reduction of CO emissions.

Once this real and proper “stone catalyst” has reached the

working temperature, it contributes determinedly to the

wood’s complete combustion.

The organic molecules are thus transformed in primary

gaseous elements and solid residual products. The first

are burnt, the latter, in the intensive heat, burn thanks to

the secondary air, with the so called “slow flame”, which

enables the boiler to operate for longer, and so reduces the

need of refuelling.

At the end of the process, the noncombustible ashes will fall

into a large ash pan placed underneath the grate.

The passage of the flue gasses takes place vertically, from

the bottom to the topmost direction, then they enter the

“tunnel” in the vault, built in a special refractory catalyst

material, and enter head-on into the hollow space between

the latter and the arched vault, soaked by the system’s

water, then they flow out through the rear outlet.

Expansion Tanks &

Pressurisation Systems

Expansion tanks for use in a closed heating or cooling system are

available in various types and sizes.

The type and size of tank used is usually governed by the intended application and can range

from simple expansion tanks which are pre-charged and sized according to the design

fill pressure and requirements of the system, through to pump controlled pressurization

systems which may include degassing functions.

Introduction to Expansion Tanks

& Pressurisation Systems

EXPANSION &

DEAERATION

Why do we need

Expansion tanks?

Expansion Tanks & Pressurisation systems are critical to

the successful operation of heating and cooling circuits and

must essentially fulfil three fundamental tasks:

• Maintaining the pressure within permissible limits at

every point of the system, that is, the permissible working

pressure must not be exceeded as well as maintaining

a minimum pressure to prevent vacuum, cavitation and

evaporation of the system liquid, e.g. in circuits with

superheated water, solar systems.

• To prevent a negative pressure at the highest points of the

installation in order to avoid the intrusion of air into the

piping network.

• Compensation of volume fluctuations of the heating or

cooling water due to temperature fluctuations.

• Providing a water seal to prevent system-related water

losses.

With any heating or chilled water system there is expansion

and contraction as the system water is heated or cooled.

Because water is incompressible, the pressure in the

system will increase or decrease accordingly. To prevent

damage to the system components, expansion tanks are

installed which contains the excess volume as the water

heats and expands and allow that water to fill the vacuum

created when the system water cools and contracts.

Careful calculation, commissioning and maintenance are

the prerequisite for the correct functioning of the overall

system.

Expansion tanks in open vs.

closed systems

Open header or feed tanks were an early form of

expansion tank which were usually copper lined open

tanks installed above the highest point of the system as

the tanks relied on gravity to maintain system pressure.

Apart from the connection to the system, the tanks

were fitted an overflow outlet and a mains water inlet

controlled by a floating ball valve which allowed the

system water to be replenished automatically if needed.

While functional, open header tanks fail to provide

an optimal solution to the expansion problem due to

several key issues.

• Because the tanks are unsealed, the system water is

constantly exposed to the air which allows the system

water to absorb oxygen. Oxygen in the system leads to

corrosion and decreased pump efficiency.

• Depending on the design of the tank, there may be the

potential for backflow if the water level rises above

the mains inlet, leading to contamination of the water

supply.

• With any open tank, there is the potential for overflow

which is normally piped to the nearest drain. Given that

the tank needs to be elevated, if the drain becomes

blocked or the tank leaks, the resulting spillage may

cause damage to surrounding building surfaces.

• Because the system is open, system pressure is limited

to the head pressure achieved by the height of the

tank. This may negatively impact pump performance

due to insufficient NPSH (Net Positive Suction Head),

potentially resulting in cavitation and pump failure.

• Many modern boilers require controlled system

pressures and water quality and are therefore not

suited to open vented systems.

To overcome these issues, most heating and cooling

systems are now designed as closed systems which

allows system pressure to be controlled and gases

to be eliminated, resulting in greater efficiencies and

improved performance across all components of the

system.

Types of Expansion tanks

Static Expansion tanks

Static expansion tanks are available in a range of sizes to

accommodate various system volumes and are supplied to

order pre-charged with nitrogen to the pressure required

for the intended installation. The pre-charged expansion

tanks come in two types:

• Diaphragm type, in which the diaphragm spans the middle

of the tank. The water in the tank is in contact with the tank’s

metal inner surface and therefore is unsuitable for potable

water.

• Bladder type, which contains a butyl bladder. Because

the water in the tank is completely contained inside the

membrane, the risk of corrosion is avoided and the tank is

suitable for systems containing untreated water.

Regular maintenance required for pre-charged expansion

tanks includes complete draining and pressure testing at

least annually.

Diaphragm Type

Bladder Type

Pump-controlled Pressurisation Systems

Pump-controlled Pressurisation Systems operate as

pressure-maintaining stations with automatic water makeup

and deaeration. Typically, a pump-controlled expansion

tank comprises a tank fitted with a replaceable butyl (bag

type) diaphragm, a pump and a control panel. This type of

system represents a superior method of system pressure

management, provides close pressure control, degassing,

and water-makeup with BMS interface capabilities.

Pressure control with this type of system is much more

fine-tuned and up to 90% of the tank’s capacity can be

utilized, compared to less than half that volume with a precharged

tank (depending on system pressure). This saves

a significant amount of plant room space and piping. One

pump-controlled expansion tank can be substituted for four

pre charge vessels.

Examples of this type of expansion tank include Duraflex

EcoPress and Duraflex EcoPress Compact.

The expansion tank sizing formula is as follows:

(based on Boyles Law)

Cooling System

The vessel sizing formula is as follows:

(based on Boyles Law)

e x C

Vt = 1 - (Pi/Pf) =

Vu

1 - (Pi/Pf)

Vt =

e x C

1 - (Pi/Pf)

where:

Vu =

Total useful volume of tank = Vi - Vf

Vi = Initial volume

Vf = Final volume

e = Expansion coefficient

Pi = Initial charge pressure (absolute) of vessel.

This pressure must not be lower than the hydrostatic pressure at the point

where the tank is connected to the system.

Pf = Maximum operating pressure (absolute) of the

relief (safety) valve

taking into account any differences in level between the vessel

and the safety valve.

C = Total water capacity of the system in litres:

boiler, pipework, radiators etc

(as a general approximation, C is between 4 and 8 litres

for every kW of boiler output)

Note: Calculations must be done in Absolute Pressure

e.g. 100kPa = 200kPa absolute.

In standard heating systems:

e = 0.04318 (Tmax = 99°C, Tmin = 10°C, Δt = 89ºC, C = 0.035)

In standard cooling systems:

e = 0.011 (Tmax = 50ºC, T min =4ºC)

Pi = Maximum plant pressure, corresponding to the maximum

achievable temperature, equal to the ambient temperature,

which is recommended to be fixed at 50ºC

Pf = The final working pressure achieved at minimum

temperature, using 4ºC

Example

C = 500 litres

Pi = 150kPa (250kPa Abs)

Pf = 400kPa (500kPa Abs)

V = 0.04318 x 500 = 43.2 litres

Calculating Expansion Tank

Pre-charge Pressure

Please use the below calculation to correctly determine

the expansion tank pre-charge pressure:

Pi = [Hm x 10] + 20kPa

where:

Pi = Initial charge pressure (absolute) of vessel

Hm =

System height (metres) above the location of the

expansion tank

Installation

1. The expansion tank must be installed on the suction

side the system pump and preferably in the coolest

part of the system e.g. on return to boiler.

2. Ensure water entering the tank is less than 70ºC,

to prevent premature diaphragm failure. If water

temperature is higher than 70ºC, an intermediate tank

must be installed between the expansion tank and the

system.

3. The expansion tank must be installed with a lockable

service valve and drain point. This is to ensure the tank

can be serviced properly in the future.

4. The expansion tank must be installed with a pressure

relief valve between the tank and the lockable service

valve, to protect the tank from overpressure situations.

5. The pressure relief valve rating must be no higher than

the safe working pressure of the expansion tank.

Commissioning

Please follow the below 4 step process for commissioning

an expansion tank:

1. Disconnect

a. Isolate the expansion tank from the system via the

lockable service valve. This is crucial to ensure an

accurate pressure reading.

b. Disconnect from the system and drain the tank.

2. Test

a. Calculate the correct expansion tank

pre-charge pressure.

b. Test the pre-charge pressure in the expansion tank

via the Schrader valve.

3. Charge

a. Charge the expansion tank to the correct (see note

on calculating pre-charge pressure) pressure via the

Schrader valve, using an air compressor or nitrogen

canister.

b. Recheck tank charge to ensure pre-charge pressure

is holding. If a leak is found, the Schrader valve or

the expansion tank will need replacing.

4. Reconnect

a. Reconnect the expansion tank to the system.

b. Re-pressurise the system and check for leaks.

Maintenance

Please follow the below 5 step process for maintaining an

expansion tank:

1. Inspect

a. Perform a visual check of expansion tank to ensure

no obvious damage or corrosion is present.

b. To check the integrity of the diaphragm, press

down the Schrader valve. If water exits the valve,

the diaphragm has ruptured and the expansion tank

will need replacing.

2. Disconnect

a. Isolate the expansion tank from the system via the

lockable service valve. This is crucial to ensure an

accurate pressure reading.

b. Disconnect from the system and drain the tank.

3. Test

a. Calculate the correct expansion tank

(see note on calculating pre-charge pressure)

b. Test the pre-charge pressure in the expansion tank

via the Schrader valve.

4. Charge

a. Charge the expansion tank to the correct precharge

pressure via the Schrader valve, using an air

compressor or nitrogen canister.

b. Recheck tank charge to ensure pressure is holding.

If a leak is found, the Schrader valve or the

expansion tank will need replacing.

5. Reconnect

a. Reconnect the expansion tank to the system.

b. Re-pressurise the system and check for leaks.

Duraflex EcoPress® Compact


EXPANSION &

DEAERATION

The EcoPress Compact (compressor-controlled).

EcoPress pressurization stations regulate the pressure on

the gas side of the vessel by means of compressor:

• When the set pressure is exceeded, the overflow valve

opens and releases air from the expansion vessel. Due to

the drop in pressure on the air side, water flows into the

expansion vessel and pressure falls in the system.

• If pressure falls below the set pressure, the compressor

switches on and pumps air into the air side of the expansion

vessel, forcing water into the system: the water level falls in

the vessel and pressure rises in the system.

• Additional units for water make-up and degassing can be

added to the EcoPress. The possibility of the intelligent

integration of a water make-up system is incorporated into

the EcoPress Control.

EcoPress Compact

• Compact compressor-controlled pressurization station for

heating and cooling water systems.

Duraflex EcoPress®


Pressure-maintaining station with automatic

water make-up and deaeration.

The pump-controlled EcoPress opens up a completely new

dimension of pressure-maintaining stations for heating and

cooling circuits. Its five functions are:

• it keeps the system pressure within very restricted limits

• it deaerates the content water

• it makes up water automatically

• maintaining system pressure within 50kPa

• provides outputs to BMS systems

EXPANSION &

DEAERATION

Thus, the Duraflex EcoPress is a solution to decrease air

problems, especially within closed heating installations,

which, according to a study of the Technical University of

Dresden, arise in more than 50% of the installations.

The Duraflex EcoPress ensures air-free installations up

to the top floor and into the last corner. An additional

advantage: A special data interface allows the integration

into the modern facility management.

The high efficiency of the EcoPress principle has been

proven and tested in numerous application examples. The

combination of pressure maintenance, deaeration, and

water make-up complies with all requirements for air-free

systems and requires only little maintenance.

Advantages

EcoPress / EcoPress Giga advantages against a Fillset with Pre charge Vessels

Pressure Control

• Keeps pressure +/- 0.2 bar limits

• Spill valves, proportionally controlled motorised ball valves

and not solenoids

• Ball valves afford tighter volume/pressure control without

clogging (as per solenoid valves)

• No water hammer – as sometimes happens with solenoids

on other systems

• No regular maintenance and checks as per pre charged

vessels

• Software with alarms protect the EcoPress/system via BMS

• If unit is set up correctly then basically a “ fit and forget”

type installation.

• High Integrity information output to your BMS so system

information may be mapped and safety parameters alarms

to suit your requirements.

Degassing

• Integral atmospheric degassing facility (not available on fill,

pre charge or other types)

• If high temperature between 70ºC and 90ºC use Duraflex

Vacuum Deaerator Degassing

• Degassing helps to improve hydraulic balancing and

ensures circulating pumps run to curve. The risk of

mechanical seal failure and damage to windings on

glandless pumps is significantly reduced due to good

hydraulic properties. The flow characteristics of devices

such as plate heat exchangers, boilers etc will be found to

be as published. All of these factors enable the specified

system performance to be readily achieved ensuring a

timely handover to the final client.

Space Savings

• Acceptance Factor on these vessels 90%

• One EcoPress vessel to 4 pre charge vessels (due to

acceptance factors)

• Cost savings on Vessel amount and also installation and

materials (piping etc)

Expansion Bend

Guarantees the pressure

compensation towards

the atmosphere between

the vessel wall and the

diaphraghm

Heavy Duty

Steel Tank

Technology and Alarm Safety

• Microprocessor technology includes power fail safe relay

/ soft starters / various alarms re high and low pressures

and water reserve levels / error messages. Manual checks

of pumps, spill valves & fill solenoid/fillset P plus many

other features. Real time log of alarm conditions

• All BMS outputs are volt free and most beneficial is an

extension module which gives discrimination for HP/LP

conditions etc. Analogue outputs enable remote monitoring

of system pressure and vessel volume.

• Pumped system integrity monitored by multiple filling

safety alarms monitoring water make up duration and

repetitive filling.

Maintenance

• The operating system is easily understood and works with

pre-programmed defaults operating around a single setting

for the operator.

• Minimal maintenance with yearly warning in display when

service is scheduled.

• All default parameters may be changed by a Automatic

Heating Service Engineer to suit your system/BMS

requirements.

Financial Benefits

• Quicker handover of whole project to client due to optimised

hydraulic performance.

• Enhanced system control ensures an almost constant

pressure regardless of temperature. Reduced risk of

leakage from joints etc on existing pipe systems.

• Less space taken with fewer vessels as space in many

instances is a premium

• Minimal maintenance cost with only “Health Check” cleaning

of dirt traps and buffer vessel gas charge required.

System pressure is

constant, unit at rest

For Cooling

System pressure

increase is detected.

Hence, water flows

into the bladder

through the open valve

and is de-aerated due

to pressure drop.

The unit reaches

almost full capacity

when the temperature

increase is completed.

Pressure is maintained.

System pressure

decreases; the

deaerated water

is pumped back to

the system until

pressure’s setpoint is

restored.

If the vessel’s water

volume drops under

critical level, the unit

refills the bladder

until minimum water

a leakage monitor and interrupted

in the event of any malfunctions.

Deaeration

A part flow of the heating water is

released into the basic vessel and

thus degassed. The deaeration mode

can be selected from the following

versions:

• Continuous deaeration: constant

deaeration after startup and repairs

in the supply system, to allow all

residual air to be removed from the

system.

• Follow-up deaeration: activated

automatically after continuous

deaeration and performed after

every pump operation.

• Interval deaeration: performed after

a specified schedule.

Note: The useful volume rate is 90 % for

the pump controlled pressurisation units.

Therefore according to calculations the

required expansion tank size is smaller

than static tank size.

Duraflex EcoPress Giga - Pressurisation Systems

Features

Innovative Technology and Reliability

The Duraflex EcoPress Giga offers by default an automatic,

controlled water makeup. The water make-up is controlled

in dependence on the water level in the GG primary vessel.

An even more comfortable solution: Equip the Duraflex

EcoPress Giga with the Duraflex EcoPress Vacuum

Deaerator vacuum spray tube deaeration. It does not only

free the make-up water from dissolved gases, but also

ensures that the content water in the system is almost gasfree.

“Air problems“ due to free gas bubbles at system high

points, at circulating pumps or control valves are a thing of

the past!

Modular Design and Customisation

• For heat generating systems up to and over 120°C.

• Heating capacities up to 250 MW and more.

• Pressures also above 40 bar.

• Expansion volumes up to 160,000 liters.

• Medium pressure maintenance in case of complicated

pressure conditions.

• Fully automated operation with individual operating

program and SPS.

• Suitable for high temperature hot water plants.

The expansion bend

ensures the pressure compensation

towards the atmosphere between

reservoir wall and diaphragm.

GH Hydraulics

The 10 design models of the GH

hydraulic system allows the hydraulic

adjustment to the most different

systems and environments.

The sounding pipe

deaeration extracts the gasses

from the tank and prevents a

Dirt and Air Separation

Dirt and Air

Separation

Foreign particles and substances can significantly reduce the performance

and service life of heating & cooling systems and increase service intervals.

Our dirt & air separation solutions can help to prevent this and achieve optimum operating conditions.

Duraflex separation technology uses mechanical separation processes, for which no auxiliary energy is

needed. Duraflex Vacuum Deaerator degassing systems even degas dissolved gases in a vacuum. The

process is electronically monitored and optimized by a Duraflex Control unit.

Air

Due to the physical nature of water, it is impossible to

prevent air from becoming trapped in the system.

Air can enter through:

• Filling and makeup water

• System alterations and maintenance

• Open header tanks

• Micro leaks and diffusion through system components

• Henry’s Law - “Gas is a natural constituent of water and

other liquids. The presence and solubility depend on

temperature and pressure within the liquid” (William Henry

(1775 – 1836)

Free Air

Microbubbles

Dissolved Air

Once in the system, gas can be observed in

three different forms

As Henry’s Law describes, the presence and solubility of

gas in a liquid depends on two elements – temperature and

pressure. Whereas a hot water system causes the water to

expand and the gas more easily removed, a chilled water

system results in the water becoming dense and the gas

more soluble.

Similarly, where the system pressure is low, degassing is

more easily achieved. But as the pressure increases, not

only is the presence of gas greater but it also becomes

much more difficult for traditional methods of removal –

such as air vents – to release it.

Free Air

“Free” gas or air is both the most common and most easily

removed, as it has not yet become soluble in the water. It

can be found as air pockets and is typically released via

simple air vents strategically place
