An air source pump is an alternative way to heat your home. It will enable you to generate your own renewable heat and potentially save money on your energy bills.

They deliver heat at lower temperatures than gas and oil boilers. So you’ll need to run them for much longer periods to heat your home to a comfortable temperature. 

Heat pumps can save you more on your heating bills if you’re replacing an expensive system such as electric storage heaters, oil, LPG (liquefied petroleum gas) or coal, rather than gas. But remember, a well-insulated home is essential – otherwise the heat the pump is generating escapes more easily.

High efficiency
  • May save you money overall on energy bills
  • Health and wellness benefits
  • Heating and cooling system all-in-one
  • Able to create zones to heat and cool rooms at different temperatures
Air source heat pump advantages
  • Energy efficient and low carbon – air source heat pumps generate less CO2 than many conventional heating systems
  • Less disruptive than installing a ground source heat pump, especially if you’re retrofitting
  • You could save money on heating compared with some older systems
How does an air source heat pump work?

An air source heat pump takes heat from the air and boosts it to a higher temperature using a compressor. It then transfers the heat to the heating system in your home.

They work a bit like refrigerators in reverse.

  1. he air source heat pump absorbs heat from the outside air into a liquid refrigerant at a low temperature.
  2. Using electricity, the pump compresses the liquid to increase its temperature. It then condenses back into a liquid to release its stored heat.
  3. Heat is sent to your radiators or underfloor heating. The remainder can be stored in your hot water cylinder.
  4. You can use your stored hot water for showers, baths and taps.

The pump uses electricity to run, but it should use less electrical energy than the heat it produces. This makes them an energy-efficient way to warm your home.

Air source heat pumps work even if the temperature is well below zero.

Ground source heat pumps also harness natural heat and increase the temperature to warm your home

What is an air source heat pump?

An air source heat pump is a low-carbon way of heating your home. They absorb latent heat from the outside air and use it to increase the temperature inside your home. 

Air source heat pumps look similar to air-conditioning units. Their size depends on how much heat they'll need to generate for your home - the more heat, the bigger the heat pump

Are air source heat pumps efficient?

An air source heat pump system can help to lower your carbon footprint as it uses a renewable, natural source of heat – air

A heat pump needs a power source, usually electricity, to power the heat pump, so there will still be some resulting CO2 emissions.

To get the best from your heat pump, you'll need to know how to use it most effectively. Often you'll need to set your heating to come on for longer than with a traditional system.

You should also have your heat pump serviced every two to three years. Check that any grills are free of leaves and debris on a regular basis and follow any maintenance checks advised.
