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 


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.

times to benefit from low cost power 

30% Space Saving due to Y Frame design (CHP-80) 

Versatile - Suitable for a wide range of purposes, from 

small facilities to large buildings where hot water or 

heating is required. 

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 ozonedepleting 

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.

Revere® CO 2 


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.

Louvred Fins 

Spiral copper coil enlarges the water heat exchanging area 

so that the water can sufficiently exchange heat with gas. 

Finned Heat Exchanger 

The finned heat exchanger uses riffled copper tube which greatly 

improves the heating efficiency. Louvered fins with greater airflow 

distribution effectively improve the heat exchanging efficiency. 

Tube-in-shell Heat Exchanger 

The small gap between the refrigerant circuit & shell makes the 

lubricant flow smoothly and prevents lubricant retention. Water 

and refrigerant circuit is of counter current design, ensuring the 

refrigerant outlet subcooling.

0.5ºC Precise Control 

The units can change the operating frequency of the 

compressors automatically according to the heating or 

cooling demand. When the target temperature is reached, the 

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.

Speed up Heating/Cooling Time 

When there is a large difference between the actual temperature 

and the programmed temperature, the unit can run at a higher 

frequency to make fast heating or cooling to increase or decrease 

the temperature rapidly. 

No Frosting in the Bottom of 

Air Exchanger 

With the use of the special liquid distribution technology, in heating 

mode, the temperature of refrigerant in the air exchanger’s bottom 

copper tube will not decrease in order to ensure smooth drainage 

with no ice.

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.

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).

• 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

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.

Contents 


• 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.

• 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 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.

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.

capability 

High water content allows greater 

water temperature and flow variations 

Patented Multi Radial flue gas 

fins for superior heat transfer 

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.

The Eurogen Condensing Fire Tube Boiler combustion process is designed to maximise efficiency 

and performance. The hot combustion gases first pass down the centre and return along the wall 

of the combustion chamber. On reaching the specially contoured door of the boiler the gases are 

directed down into the stainless steel condensing tubes which comprise the heat exchanger and 

feature aluminium internal fins designed to maximise heat extraction.

Condensing Boilers 175 – 1250kW 

High Water Volume Condensing Boilers with 

large capacity range. 

Euromax Condensing Boilers are distinguished by their 

robust engineering, cost effective design and wide range of 

features. Manufactured to AHG specifications and exclusively 

distributed in Australia by AHG, Euromax provides a high 

efficiency heating solution built for performance and 

longevity. Its durability can be attributed to its full 316 

Stainless Steel combustion chamber and heat exchanger, 

while its high efficiency is derived from its three pass design 

and effective heat transfer system. 

Available in output ranges from 175kW to 1250kW, Euromax 

Condensing Boilers constitute a range of 3 pass condensing 

boilers which fully conform to Australian Standards and are 

manufactured from AISI 316L stainless steel . The third pass 

of exhaust gases is through stainless steel tubes fitted with 

stainless steel fins to maximise heat exchange. The boiler 

includes low temperature (Rbt) and high temperature (Rat) 

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.

CONDENSING & 


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 thirteen 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.

Contents 


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. 

CONDENSING & 


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.

Pre-assembled Thermal Elements 

MODULEX EXT is an assembly of thermal modules, together 

making a complete unit. Every unit is constituted by preassembled 

thermal elements, in Al/Si/Mg. Every element 

supplies, in continuous and progressive way, from 12 to 50 

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.

Output Flexibility and Efficiency 

CONDENSING & 


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 central heating 

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 central 

heating 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 central heating and D.H.W. 

production, with a lower noise level 

than the traditional boilers

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 


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 and a combustion 

system which delivers exceptional energy efficiency as 

well as advanced ultra low NOx performance of 35mg/ 

kWh (Class 5).

2-channel valves isolate the boilers 

when they are not operating. On 

start up the boilers are blocked until 

their respective isolating valves are 

fully open. The Cascade function is 

integrated and a BUS module just 

needs to be added to each boiler 

regulator.

Optimising the condensing 

"Cold" returns are used more, 

Thanks to the buffer tank, short 

cycles at high temperature are made 

smoother: loop losses, low drawing. 

The time for the boiler to reach its 

temperature is covered by the buffer 

tank; the tank's contents must be at 

least 2.5 l /kW of installed power at 

high temperature.

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.

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 • AB: High / Low 

• PR: Progressive • 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.

CONDENSING & 


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.

minimise environmental impact. These units also feature 

simplified maintenance through convenient access to

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.

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 & 

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.

Heating System 

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.

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
