Frequently asked questions about Air Source Heat Pumps

How do Air Source Heat Pumps work?

An ASHP uses energy from the outdoor air. Air is pulled across a heat exchanger inside the heat pump where the energy is extracted by refrigerant gases. These gasses are compressed via a compressor to give useable heat.  This heat is transferred to your heating system in the same way as a conventional boiler sends heat to your radiators, underfloor heating or hot water cylinder so it is ready whenever it is needed.

How much will an Air Source Heat Pump installation cost?

An example of a typical 3-bedroom detached bungalow that has an oil boiler and 9 radiators will cost approximately £15,000 to change the heating system to Air Source Heating.

If you are eligible, you could expect to receive government incentives of £9,500 through the Renewable Heat Incentive.

It is estimated you would benefit from £2,500 fuel savings over the 7 year period.

The costs involved in installing a system include the following:

  • Removal of the existing system.
  • Custom design of a heating system for your property.
  • Installation of the air source heat pump (unit fitted outdoors).
  • Installation of a new cylinder that has an increased size primary coil fitted.
  • Installation of a buffer vessel (another cylinder for the heating system fluid).
  • Replacement of the radiators with new, larger radiators.
  • Replacement of the current heating controls.
  • Electrical wiring of the new system. Often a new supply will need to be run from the consumer unit to the outdoor air source heat pump.
  • Plumbing required to adapt the old heating and hot water systems to the new heat pump and radiators.
  • Registration and certification for Microgeneration Certification Scheme so that you will be eligible for the Renewable Heat Incentive.

Will I have lower energy bills if I install an ASHP?

If you are changing from LPG, oil or direct electric there are considerable savings to be made in your annual running costs.

An air source heat pump generates 3 times the energy it consumes, this means that for every 1kw of electricity that you pay for, an ASHP can produce 3kw of heat for your home.

Does the government offer incentives to install an ASHP?

The government does currently offer incentives, the Renewable Heat Incentive is currently available. Full up to date information on the current schemes and eligibility is available and detailed on our Incentives page.

Can I use my existing radiators with a new Air Source Heat Pump?

If the radiator in a room is sized correctly for that room and currently being heated by a gas or oil boiler, then it is not likely to be suitable to be used with an ASHP.  A new radiator sized correctly to work with an air source heat pump will be needed.

How many years will my ASHP run for?

The external unit is expected to last up to 20 years on a system which has been designed and installed correctly.
