Air Source Heat Pumps

What is an Air Source Heat Pump?

An Air Source Heat Pump is a low carbon, alternative method to heating your home and hot water. The heat pump extracts ambient heat from outside, which causes the refrigerant inside the heat pump to become warmer. This is then boosted to a higher temperature using a compressor. The heat is then transferred and distributed around your home.

Although an Air Source Heat Pump is powered by electricity, it actually uses less electrical energy than the heat it produces making them far more efficient than a boiler. Air Source Heat Pumps are a great way to get away from using Gas, oil or LPG.

How does it work?

  1. Outside air is blown over a network of tubes filled with a refrigerant. This warms up the refrigerant, and it turns from a liquid into a gas.

  2. This gas passes through a compressor, which increases the pressure. Compression also adds more heat – similar to how the air hose warms up when you top up the air pressure in your tyres.

  3. The compressed, hot gases pass into a heat exchanger, surrounded by cool air or water. The refrigerant transfers its heat to this cool air or water, making it warm. And this is circulated around your home to provide heating and hot water. Meanwhile, the refrigerant condenses back into a cool liquid and starts the cycle all over again!


Air source heat pumps use well-established technology and may have a working life of 20 years or more. But just like a boiler, you should get your air source heat pump professionally serviced – every two or three years (or annually, if you have a compressor inside your home) – to make sure that it’s still working at its best. There are some things you can do yourself:

  • Be sure that there’s a plentiful supply of air. This means regularly checking for leaves or rubbish caught in the fan’s grilles. And pruning back any plants growing too close to the unit or its pipes.
  • In very cold weather clear snow from the air source heat pump and check that the grilles aren’t blocked by ice.
