Air Source Heat Pumps

Reduce Carbon Footprint and bring down your energy costs with an ASHP

Renewable Heat Incentive

The Domestic Renewable Heat Incentive (Domestic RHI) is a government financial incentive to promote the use of renewable heat. Switching to heating systems that use eligible energy sources can help the UK reduce its carbon emissions and meet its renewable energy targets.

People who join the scheme and stick to its rules receive quarterly payments for seven years for the amount of clean, green renewable heat it’s estimated their system produces.

The Domestic Renewable Heat Incentive has been extended until 31 March 2022. For further details about this and the non-domestic scheme click here

How does an ASHP work?

 An air source heat pump works by transferring heat absorbed from the outside air to an indoor space.

It uses a refrigerant system involving a compressor and a condenser to absorb heat at one place and releasing it to another.

This is then heated to the required temperature for the home and warm air or water is generated

What do they look like?

 Air source heat pump units look very much like air conditioning units that you may have seen in an office building or in warmer climate countries. The size of the heat pump will be determined by a number of factors based on your home’s heat demand mainly the size of your property, and how well it is insulated.

A typical unit might be a meter high by a meter wide with a depth of about half a meter. This will obviously vary greatly between models, but it gives you an idea.


 The heat pump itself is generally fitted outside in a position where it will receive good airflow. It then supplies hot water to the indoor unit (usually stored in a utility room, airing cupboard or even under the stairs) which in turn delivers it to your chosen central heating emitters (radiators, underfloor heating).

It can also supply a cylinder for providing hot water.


 It is a requirement of a manufacturers warranty to service an Air Source Heat Pump (ASHP) annually. It is also a condition of the Renewable Heat Incentive (RHI) that your unit is operating effectively and the best way to do this is to ensure it is suitably maintained.

Ecoheat ASHP Ltd can offer servicing of an ASHP (up to 22kW)

What are the estimated costs?

 Every installation is different as it depends on several factors but you can expect to pay between £5,000 – £8,000 for a well insulated three/four bedroom house.

Lower running costs are associated with this form of renewable technology which makes it very attractive.

There may be grants or inititives available to help you fund the cost of installing an ASHP.
