Air Source Heat Pump (ASHP)


Air Source Heat Pump (ASHP)

What is an Air Source Heat Pump?

Air Source Heat Pumps (ASHPs) absorb heat from the outside air. This heat can then be used to heat hot water, underfloor systems and radiators. An Air Source Heat Pump is usually placed outdoors at the side or back of a property. It looks similar to an air conditioning unit. It extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as 15 °c.

How does an Air Source Heat Pump work?

Heat from the air is absorbed at low temperature into a fluid. Using electric, the pump compresses the liquid where its temperature and pressure are increased. This then condenses back into a liquid to release stored heat and transfers its higher temperature heat to the heating and hot water circuits of the house. The liquid then passes through an expansion valve, reducing its pressure and temperature, which then the process repeats itself. 

Why choose an Air Source Heat Pump?


Under the UK Government’s domestic Renewable Heat Incentive (RHI) scheme, you could receive quarterly cash payments over seven years if you install or have already installed an eligible renewable heating technology

What is the RHI?

The Renewable Heat Incentive (RHI) is a UK Government scheme set up to encourage uptake of renewable heat technologies amongst householders, communities and businesses through financial incentives. It is the first of its kind in the world and the UK Government expects the RHI to contribute towards the 2020 ambition of 12% of heating coming from renewable sources.

The domestic RHI was launched on 9th April 2014 and provides financial support to the owner of the renewable heating system for seven years. The scheme covers England, Wales and Scotland and is targeted at - but not limited to - off-gas households.
