Heat pump technology<br />
Air source heat pumps<br />
Air source heat pumps use basic thermodynamic<br />
principles to convert latent heat contained within<br />
the air we breathe into heat energy that can be<br />
used to provide heating and hot water.<br />
This ‘ambient heat’ is replenished by the sun making our heat<br />
pumps both effective and environmentally friendly.<br />
Fit for the future<br />
With the recent fluctuations in price and supply of fossil fuels,<br />
air source heat pumps offer both an environmentally and<br />
economically sustainable alternative.<br />
Home heating in the <strong>UK</strong> accounts for approximately 30% of CO2<br />
emissions. The heat source used by <strong>Grant</strong> Aerona heat pumps<br />
is entirely renewable which helps reduce the amount of harmful<br />
greenhouse gases being released into the atmosphere and, in<br />
so doing, lowers the carbon footprint of the household.<br />
How it works<br />
There are two basic types of air source heat pump - ‘air to air’<br />
and ‘air to water’. <strong>Grant</strong> Aerona heat pumps use an air to water<br />
system which utilises heat energy captured from the air in 'wet'<br />
heating system radiators or underfloor heating.<br />
The process uses the same vapour/compression cycle that<br />
extracts heat in a domestic fridge. A refrigerant with a low<br />
boiling point is exposed to external air temperatures in an<br />
evaporator. The liquid boils off to a gas and absorbs the latent<br />
heat energy of the air. This gas is then compressed increasing<br />
the heat content in the refrigerant, before passing through a<br />
heat exchanger where it condenses back to a liquid state while<br />
transferring the heat to the water of the heating system. The<br />
liquid refrigerant is then re-circulated through the evaporator and<br />
the cycle is repeated.<br />

Heat pump installation<br />
Typical system layout<br />
The house below shows a <strong>Grant</strong> Aerona<br />
incorporated into a standard heating system,<br />
comprising heat pump, cylinder, underfloor<br />
heating and radiator circuit.<br />
<strong>Grant</strong> Solar Thermal is also a good match for air source heat<br />
pumps and when combined using one of <strong>Grant</strong>’s high efficiency<br />
heat pump cylinders and solar thermal system, can reduce<br />
home heating bills even further.<br />

Green savings<br />
Lower heating costs<br />
Compared with other domestic heating methods, a<br />
<strong>Grant</strong> Aerona heat pump can benefit homeowners<br />
by creating annual savings on fuel bills.<br />
The units can deliver around four times the amount of energy for<br />
every 1kW of electricity used (depending on the model, at 7°C<br />
air temperature/35°C water temperature).<br />
Homes utilising this type of heat generator will obviously have a<br />
lower dependency on fossil fuels, making them less susceptible<br />
to rising fuel costs.<br />
About ‘Coefficient of Performance’ (COP)<br />
The COP is the ratio of electrical power required to run the heat<br />
pump, compared with the output being produced to heat the<br />
water of the heating system.<br />
Testing is carried out to European and British Standard BSEN14511<br />
and establishes the output and COP at a specific ambient air and<br />
circuit water temperature. This is 7°C for ambient air and 35°C for<br />
water flow temperature. For example, the <strong>Grant</strong> Aerona ASHE65<br />
model produces 6.5kW at a COP of 4.1, when tested to this level.<br />
This means for every kilowatt (kW) of energy used to run the Aerona,<br />
4.1kW of energy is being given to the heating system in return.<br />
It is important to note that as the outside air gets colder, the output<br />
and COP of an air source heat pump falls, due to the reduced<br />
amount of heat energy available from the air. Conversely, when<br />
outside air temperature rises above 7°C the output and COP will<br />
increase (see performance graphs on pages 7 and 9).<br />

<strong>Grant</strong> Aerona range<br />
The Aerona<br />
Our original range of single phase air to water<br />
heat pumps, feature weather compensation, dual<br />
temperature controls and a 3kW immersion backup.<br />
The integration of weather compensation with these controls<br />
allows the unit to perform very efficiently, giving a reliable heat<br />
output and using less power, resulting in lower running costs.<br />
The design also makes installation straightforward into either<br />
a new or existing S-plan type system configuration.<br />
The Aerona is available in outputs of 6.5kW, 8.5kW, 11kW and<br />
13kW (Note: this output does not include the immersion back up).<br />
Design<br />
<strong>Grant</strong> has combined tried and tested technology with<br />
sophisticated control equipment to give customers the benefit<br />
of efficient and reliable renewable heating with every Aerona air<br />
source heat pump.<br />
The performance of a heat pump is affected by outside air<br />
temperature. <strong>Grant</strong>’s factory fitted weather compensating device<br />
enables Aerona heat pumps to accurately monitor outside<br />
temperature conditions and precisely control its operation,<br />
maximising efficiency.<br />
The units are pre-plumbed and pre-wired with an independent<br />
heating element that automatically provides a boost on the<br />
rare occasion when the air temperature falls to very low levels.<br />
It is also possible to incorporate and control a secondary heat<br />
source with this arrangement e.g. gas, oil-fired, biomass boiler<br />
(Bivalent system).<br />
The <strong>Grant</strong> Aerona is very compact, requires no additional<br />
storage space for fuel and being sited externally, leaves more<br />
valuable space inside the home. The units come complete<br />
with a galvanised steel casing, featuring a proven high quality<br />
external powder coated paint finish, which protects the internal<br />
components and case from weathering.<br />

<strong>Grant</strong> Aerona HE range<br />
The Aerona HE<br />
Following the success of the original Aerona air<br />
to water heat pump models, and in response to<br />
comments and ideas from our customers, <strong>Grant</strong><br />
<strong>UK</strong> has developed the Aerona HE range.<br />
The brief for this was straightforward - bigger single phase models,<br />
higher outputs and COPs at lower air temperatures with quieter<br />
noise levels, whilst maintaining the tried and tested features of<br />
the existing Aerona range. The new Aerona HE is available in<br />
6.5kW, 8.5kW, 12.5kW, 17.5kW and 21.5kW outputs (Note: this<br />
does not include the immersion back up).<br />
Design<br />
To achieve better COP’s, and further reduce running costs, the<br />
Aerona HE range was designed with larger evaporator surface<br />
areas, increasing the amount of air flow through the unit. The<br />
fans run at lower speeds and this coupled with the improved<br />
internal insulation has successfully decreased noise levels. The<br />
HE models also use R410a refrigerant, which allows the unit to<br />
operate at lower ambient temperatures.<br />
As with all products in the Aerona range, the models are designed<br />
to be installer friendly and come complete with factory fitted<br />
weather compensation controls, 3kW electrical backup* and<br />
flexible flow and return connections, so there are no hidden extras.<br />
*Note: to fully comply with MIS3005, the backup heater should not be energised until the<br />
minimum design temperature has been reached (e.g. -3°C).<br />
Features<br />
• High COP’s sustainable at lower temperatures<br />
• R410a refrigerant<br />
• Outputs from 6.5kW-21.5kW<br />
• Built-in 3kW electrical backup<br />
• Improved sound insulation<br />
• Adjustable legs<br />
• All models are single phase<br />
• Weather compensating control<br />
• Base tray heating element<br />
• 2 independently operating compressors<br />
(17.5kW and 21.5kW models only)<br />
• Extendable condensate deflector (all models except 21.5kW)<br />
• Simple plumbing and electrical connections<br />
• 2 year product guarantee (extendable to 5 years)<br />

General information<br />
Installation and maintenance<br />
The installation of a <strong>Grant</strong> Aerona heat pump should be<br />
carried out by a <strong>Grant</strong> G-One accredited heat pump installer.<br />
More information on this scheme is available from the <strong>Grant</strong><br />
<strong>UK</strong> website.<br />
Servicing should be carried out annually by a qualified heating<br />
engineer. During servicing it is important for the engineer to<br />
ensure that the evaporator matrix is clear of debris as any build<br />
up could significantly affect the performance of the heat pump.<br />
Guarantees<br />
<strong>Grant</strong> Aerona heat pumps are guaranteed for 2 years from the<br />
date of purchase (excluding consumable items), subject to<br />
being serviced annually and installed in accordance with the<br />
manufacturer’s instructions. This warranty can also be extended<br />
to 5 years for an additional fee. See the Aerona installation<br />
manual for further details.<br />
On completion of the installation all <strong>Grant</strong> Aerona heat pumps<br />
must be commissioned and registered online at:<br />
www.grantuk.com<br />
Renewable Heat Incentive<br />
Currently in the <strong>UK</strong>, just under half of our carbon emissions<br />
are created by heating buildings and water. Over 99% of this<br />
is predominantly supplied by fossil fuels and less than 1% by<br />
renewable energy. The proposed Renewable Heat Incentive<br />
(RHI) has been designed by the Department of Energy & Climate<br />
Change (DECC) to alter this way of living, so that by 2020, 12%<br />
of heat is generated by renewable technology, thereby cutting<br />
carbon emissions and allowing the <strong>UK</strong> to hit its binding EU targets.<br />
From October 2012, the RHI guarantees long-term payments<br />
for the end user on specified renewable installations. It includes<br />
all types of heating, from households to factories and public<br />
sector buildings. The tariffs, which will be annually adjusted<br />
with inflation, will be paid for a number of years to eligible<br />
technologies installed since 15th July 2009 with payments being<br />
made for each kWh of renewable heat produced.<br />
It is important to remember that the end user can only claim<br />
cash-back through the RHI if the product and installer are<br />
both MCS approved. MCS is an independent scheme for the<br />
certification of microgeneration products and installers. It is<br />
designed to assess these products and installers against robust<br />
criteria, which provides greater protection for consumers when<br />
fitting renewable technologies to their property.<br />
Approvals<br />

<strong>Grant</strong> Heat Pump cylinders<br />
Duplex stainless steel unvented indirect mains<br />
pressure cylinders for either the <strong>Grant</strong> Aerona or<br />
combining heat pumps with solar thermal systems.<br />
Heat pump cylinders<br />
<strong>Grant</strong> has introduced a range of<br />
stainless steel cylinders specifically<br />
matched to the Aerona, which<br />
incorporate a larger primary coil for<br />
quicker heat transference.<br />
The new cylinders are available in<br />
seven indirect single coil versions,<br />
ranging from 125-400 litres and five<br />
indirect twin coil versions ranging<br />
from 170-400 litres.<br />
<strong>Grant</strong> heat pump cylinders feature<br />
compression fittings which are<br />
conveniently located to make<br />
installation quicker and easier.<br />

Domestic Hot Water<br />
(DHW) Boost kit<br />
Whilst it is possible to raise the DHW to 60°C with<br />
an Aerona heat pump, it can be more efficient to<br />
set the hot water temperature between 45°C and<br />
50°C and utilise <strong>Grant</strong>’s Domestic Hot Water Boost<br />
kit to take the cylinder up to the desired higher<br />
temperature. This unit comprises an enclosure<br />
with 20A rated contactor, an override switch and relay, which<br />
works with the immersion element fitted in all <strong>Grant</strong> cylinders.<br />
Sealed system kits<br />
Sealed system kits are available to<br />
suit all heat pump models. The kits<br />
come in either a 12ltr or 18ltr size<br />
for standard systems and a 50ltr<br />
size for use with the ThermaWave<br />
thermal store.<br />
