Air Source Heat Pumps


Air source heat pumps draw latent heat from outside air, even on cold days, and use it for heating hot water for use in the home. Operating on a similar principle to an ordinary refrigerator, the unit which houses the fans and evaporator coil is fixed on an exterior wall of the property (similar to an air conditioning unit) and the heat pump boosts the heat from the outside air to the required level, using it to heat water in a buffer tank. The existing heating system for the house is then fed from this tank.


  • Reduced household demand on energy providers when heating your home
  • Reduced energy bills
  • Lowered energy consumption and associated carbon emissions
  • Money-earning from the Renewable Heat Incentive (RHI, see below)
  • Compact unit


  • An Air Source Heat Pump resembles an air-conditioning unit, and so installation involves simply securing the unit to your property and installing a water tank to work with the new heat pump alongside your existing heating solutions.
  • The process can be completed within one week.


  • Ideal for flats and urban properties, as the units take up little space
  • Ideal for properties without a mains gas supply
  • Ideal for replacing systems which heat with oil, LPG or electricity (such replacements will see the most financial advantage)
  • However, not every home is suitable for an air source heat pump. Air source heat pumps are most effective in very well-insulated properties. This is because they heat water to a lower temperature than traditional boilers, meaning that many older or poorly insulated buildings are not energy efficient enough to use the underfloor heating systems or low temperature radiators for which air source heat pumps are most effective.
