With air source, hot water and heating is created by capturing heat from the outside air to heat your home. However, a hot climate is not required as air source heat pumps continue to work efficiently in temperatures as low as -15°C, meaning your air source system will be efficient even on chilly winter nights!

Using the air that surrounds you to heat your home can lower your fuel bills, whilst also reducing your carbon footprint.

Air source heat pumps draw energy from the air into your home, saving you money and helping the environment!


Air source heat pumps use air from outside to heat your home and water. They are installed outside of your home (usually attached to exterior walls) and use a fan to draw in air which heats a refrigerant that is then compressed to create heat.

Using the renewable source of an air source heat pump can reduce your heating costs. The savings will depend on where you live, the size of your house and the fuel you are replacing. Air source heat pumps can also halve your home’s carbon emissions.


Air source heat pumps work by harnessing latent energy from the air to boil a refrigerant which is then compressed to generate heat to be used to produce heating and hot water.

The only input required is a small amount of electricity to run the air source heat pump. For each 1kw of electricity required, the air source system produces additional energy of up to 4kw of heat per hour. So, the more you put in, the more you get back!


There are many advantages to installing an air source heat pump, including:

  • Reduced fuel bills, particularly if you are replacing an electric heating system
  • The ability to heat both your home and your water from one source
  • 0% VAT
  • Lowered carbon footprint
  • Low pollutant
  • Few maintenance requirements
  • Potential reimbursements from Boiler Upgrade Scheme
  • Air source heat pumps are easy to install

    Customer FAQs

    An air source heat pump will typically deliver a flow temperature of 45- 50 degrees, so your existing rooms will need to be able to cope with the lower radiator surface temperature. If not, you may be advised to increase the size of your radiators.

    It’s essential to have a well-insulated house, as due to the low running temperatures of an air source heat pump you need to be able to retain heat in the property.
