An air source heat pump installation is an effective, low carbon way of heating your home. With the Government’s Renewable Heat Incentive providing cash payments for eligible installations, installing an air source heat pump is an attractive investment.
Air source heat pumps can be installed in both new and existing properties, and provide a low maintenance, energy efficient heating system.
Is your property suitable for an ASHP?
To work efficiently, air source heat pumps require a well-insulated house, in some cases older properties may require insulation upgrades prior to installing an air source heat pump.
Access to mains gas
Properties with access to main gas are suitable for an air source heat pump installation, although a greater return on investment will be seen when switching from oil, LPG or electric heating systems.
Air source heat pump installations do not require planning permission.
Heat emitter consideration
Air source heat pumps work most efficiently with low flow temperature emitters, making underfloor heating the perfect partner. Traditional radiators can still be used with air source heat pumps, although the size of these will need to be considered.

Air source heat pump installation processes
The installation process for an air source heat pump in a single dwelling would typically take 5 working days, which includes commissioning. Unlike a ground source heat pump installation no groundworks are required, and therefore the process is more akin to that of a traditional gas or oil boiler.
The air source heat pump unit will be fitted to the outside of the property, in a position with good airflow ensuring that nothing is blocking the unit.
The unit, sized around 1m wide, 1m high and 30cm deep, will be bolted to the ground, or brackets connecting it to the property in order to secure it.
Once the air source heat pump unit is installed, it will be connected to the hot water cylinder. The unit may, depending on your existing system, easily link to your water tank with limited additional works. Larger radiator units may be needed to replace your existing radiators.
As air source heat pumps have very few moving parts, they require less ongoing maintenance than traditional heating systems. We recommend an annual service to ensure that your system is running at its optimum efficiency.
From initial enquiry to ongoing service and maintenance, we are on hand to answer questions and guide you through the process of your installation.

How much do ASHPs cost to run?
Running costs for an air source heat pump installation will differ depending on the size of the area you are heating, the temperature you choose to run the system at and a number of other factors, such as your choice of heat emitter and level of insulation. Geo Green Power would be happy to give you an estimation of your running costs should you wish to discuss your project with us.
What will my return on investment be?
The return on investment you receive will largely depend on the system you are replacing, and the running costs of your air source heat pump. Installations that are replacing oil or LPG heating will produce the greatest returns. Thanks to the Government’s Renewable Heat Incentive that provides cash payments, the cost of installation is covered in the majority of cases.
What is the RHI and are Grants available for ASHPs?
The Renewable Heat Incentive (RHI) is a government scheme to encourage the uptake of renewable heat technologies.
- The domestic scheme provides payments for 7 years and applies to eligible heating systems that are used for one dwelling.
- Payments for installations are calculated by multiplying the applicable tariff by the amount of heat generated in the relevant quarterly period.
- Current RHI tariffs are 10.85 p/kWh for domestic ASHPs and 2.79 p/kWh for commercial ASHPs.
|Total RHI payments over 7 years||RHI Tariff|
|RHI technology||1 bed semidetached||2 bed semidetached||3+ bed detached||Date of application||Tariff Rate 2021/22 (p/kWh)|
|Air Source Heat Pump (ASHP)||£6,076||£9,114||£12,912||Between 01/04/2020 and now||10.92|
Recent ASHP Installation
Renovating a 1970s property and replacing oil for air
When Paul moved into his home in East Leake he discovered that the best option for replacing the 45-year-old oil boiler was an air source heat pump. Paul carefully compared the cost of replacing the old oil boiler with an up to date condensing oil boiler or an air source heat pump system. He found that, thanks to the Renewable Heat Incentive scheme, the installation costs were almost identical, and the heat pump would deliver lower running costs and have a much more positive environmental impact.
