Air source heat pump, air source heating
How It Works
Air source heat pumps (ASHPs) absorb heat from the outside air. This heat can then be used to heat radiators, underfloor heating systems, or warm air convectors and hot water in your home.
Different from a ground source heat pump, an air source heat pump 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.
The benefits of air source heat pumps
- Lower fuel bills, especially if you are replacing conventional electric heating
- potential income through the UK government’s Renewable Heat Incentive (RHI)
- lower home carbon emissions, depending on which fuel you are replacing
- no fuel deliveries needed
- can heat your home as well as your water
- minimal maintenance required
- can be easier to install than a ground source heat pump.
Unlike gas and oil boilers, heat pumps deliver heat at lower temperatures over much longer periods.
