Air Source Heat Pumps
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 extract heat from the air even when the outside temperature is as low as minus 15° C.
There are two main types:
- An air-to-water system uses the heat to warm water. Heat pumps heat water to 50-60 deg C.
- An air-to-air system produces warm air which is circulated by fans to heat your home.
The efficiency of air source heat pump systems is measured by a coefficient of performance (CoP) - the amount of heat they produce compared to the amount of electricity needed to run them. A typical CoP for an air source heat pump is between 3 – 4.
The benefits of air source heat pumps
- Reduce your fuel bills: air source heat pumps run on electricity, so there's no need to pay for gas, oil or solid fuels to heat your home.
- Cut down on wasted electricity: heating your home with an air source heat pump is much more efficient than using electric radiators.
- Save space: an air source heat pump system is compact, and requires no storage space for fuel.
