Air Source Heat Pumps (ASHPs) can be used to provide heating and hot water and can absorb heat from the air in temperatures as low as -15o C. Unlike conventional boilers, ASHPs deliver heat at lower temperatures over longer periods of time and are available in two systems; air-to-water and air-to-air.

How Air Source Heat Pumps Work?

ASHPs transport the heat from the air outside into a fluid that moves through a compressor which increases its temperature. The high temperature generated is then used to heat the property.

Air-to-water systems generate heat via a wet central heating system, whilst air-to-air systems circulate warm air through fans. Air-to-air systems are more suited to heat a property and are unlikely to provide hot water as well.

What Are The Benefits Of Air Source Heat Pumps?

ASHPs contribute to making a property more energy efficient, which in turn could lower energy bills and the properties carbon emissions. Typical installation costs are between 6,000 and 10,000 pounds, and running costs depend on the size of the property and how well insulated it is. ASHPs are powered by electricity so wont negate the need for fuel bills, however you will save on the fuel you are replacing.

Government Incentives For Air Source Heat Pumps

After installing an ASHP you may be able to receive payments for the heat you generate through the governments Renewable Heat Incentive (RHI) launching in summer 2013. Installation costs for any systems installed after 1st August 2011 may also receive a one off grant through the Renewable Heat Premium Payment Scheme (available until the RHI is introduced to domestic customers).
