How does an air source heat pump work?

Air source heat pumps work by extracting heat from the outside air similar to a fridge in reversal, which extracts heat from its inside. This heat can then be used to heat the home via radiators, underfloor heating systems and is available to provide hot water. Equally important is the fact that it is able to operate when outside temperatures drop as low as -20°C.

Typically an air-source heat pump will be able to harvest and emit 3.5 times more free energy from the air than it takes to run the pump. This is known as a ‘Coefficient of Performance’ and is directly comparable to conventional boiler efficiency.

There is also the option of a hybrid heat pump which can be installed alongside a fossil fuel boiler to help make your heating more cost efficient. To find out more, read our article What’s so special about an Air Source Heat Pump?.
