Air Source Heat Pumps

Heat your home with energy absorbed from the air around you 

Air source heat pumps absorb heat from the outside air. This heat can then be used to heat radiators, underfloor heating systems or warm air convectors and hot water in your home.

Air Source Heat Pump

Air source heat pumps offer many advantages

  • They operate up to 4 times more efficiently than a traditional heating system
  • Could lower your fuel bills
  • Could provide you with an income through the government's Renewable Heat Incentive (RHI)*
  • Greatly reduces your homes carbon emissions
  • Need little maintenance
  • Low installation cost and minimal space requirements compared to other forms of renewable energy
  • Truly practical solution whether you are looking at a new build or a renovation project
  • Is a Heat Pump Suitable for my home? 

    To tell if an air source heat pump is right for you, there are a few key questions to consider:

    1. Do you have somewhere to put it? You will need a place outside your home where a unit can be fitted to a wall or placed on the ground. It will need space around it to get plenty of air.
    2. Is your home well insulated? Air source heat pumps work best when producing heat at a lower temperature so it will work more effectively  in a home that is well insulated and draught-proofed.
    3. What fuel will you be replacing? The system will pay for itself much more quickly if its replacing an electricity or coal heating system.

    Costs, Savings and Earnings

    Installing a typical system costs around  £5,000 to £12,000. Running costs will vary depending on a number of factors - including the size of your home and how well insulated it is and what room temperatures you are aiming for.

    Your fuel costs will be lower as you will save on the fuel you are replacing and if your old heating system was inefficient you are more likely to see lower running costs with a new heat pump.  

    Below are examples of the savings you could make if switching an existing heating system in an average 4 bedroom detached home with an average heat pump installation:

    *You may be eligible to receive payments for the heat you generate through the governments Renewable Heat Incentive (RHI). This pays the owner 7.3p for every kWh of renewable heat generated by the heat pump and is guaranteed for 7 years. Click here for more information.

    How they work

    Heat from the air is absorbed at low temperature into a fluid. This fluid then passes through a compressor where its temperature is increased and transfers its higher temperature heat to the heating and hot water circuits of the house. There are two main types of air source heat pump system:


    • An air-to-air system produces warm air which is circulated by fans to heat your home. They are unlikely to provide you with hot water as well. 
    • An air-to-water system distributes heat via your wet central heating system. Heat pumps work much more efficiently at a lower temperature than a standard boiler system would. So they are more suitable for underfloor heating systems or large radiators, which give out heat at lower temperatures over longer periods of time.


    In an air-to-water system, the heat produced is used to pre-heat water in a storage tank or to circulate through a heating circuit underfloor, fan coils or radiators. Heat pumps produce hot water that is a lower temperature (typically 35°C - 45°C) than standard boiler systems, which makes underfloor heating the most effective option.

    Air source heat pumps operate up to 4 times more efficiently than a traditional heating system with greatly reduced carbon emissions.

    They also have the advantage of low installation costs and minimal space requirements compared to other forms of renewable energy products, which makes them the practical solution whether you are looking at a new build or a renovation project.
