Air Source Heat Pumps

What is an Air Source Heat Pump?

Typically, homes are heated using Gas, Oil, LPG or Electric. However, there are renewable energy alternatives that are much more efficient and provide a much more sustainable solution. The average Air Source Heat Pump runs at around 350% efficiency so could save you hundreds on your energy bills.

How does an Air Source Heat Pump work?

Air source heat pumps use air as their main source of energy. They take energy from the air outside and convert it into heat for your home. In simple terms they work in the same way that fridges and air-conditioning units do, just in reverse.

Here is a summary of the process:

  • The unit absorbs heat from the air into a liquid refrigerant. This fluid is turned into gas
  • Using electricity, the pump compresses this gas, heating it up
  • This heat is transferred into your home’s heating system – your radiators, underfloor heating and hot water
  • As the heat transfers, the gas condenses back into a liquid and the cycle begins again


A compressor unit is fitted outside of your home. It’s useful to have a sunny spot for this so the pump won’t have to work as hard. But it can even absorb heat from the air at sub-zero temperatures – so it’ll work even if you’ve only got a shady space.
