Air Source Heat Pump Installation

Frequently Asked Questions

How does an air source heat pump work?

An air source heat pump works much like a fridge, only it’s in reverse so it heats your home. Outside air is blown over a network of tubes filled with a refrigerant. This warms up the refrigerant and it turns from a liquid into a gas. The refrigerant transfers its heat to water, making it warm. This warm water is sent around your radiators or underfloor heating just like a conventional gas or oil system would, heating your home.

How much does air source heat pump installation cost?

The cost of heat pump installation depends on a number of factors. For a typical UK 3 bedroom house built in the last 60 years, the cost of the heat pump ranges from £1,500 to £3,000. The remainder of the cost is for installation as well as other factors such as home insulation. Installation costs can vary depending on accessibility, the size of the house, the existing plumbing and your location. It’s best to get in touch with our heat pump engineers to discuss pricing in more detail.

Is an air source heat pump reliable?

Air source heat pumps normally have a life span of 20 years or more if they’re well looked after and serviced regularly, making the heat pump an excellent choice for a long term heating option for the home. As they’re designed to process air rather than a physical substance such as fuel or water, a heat pump can be more reliable than boilers and oil heaters.

Are ASHPs difficult to maintain?

Once installed, an air source heat pump is very easy to maintain, however, it will need attention on a regular basis. Seasonal checks between 2 to 4 months are recommended in order to prolong the life of the heat pump, get ahead of any issue and maintain the heating efficiency of the unit.

Can I get money off of the installation of an air source heat pump?

There is a UK Government finance scheme accessible called “The renewable Heat Incentive’’ (RHI) in which owners of air source heat pumps can actually earn money for 7 years for green electricity supplied back to the grid. As long as you meet the criteria for the size of the heat pump at your home (and other factors), your heat pump may pay for itself after a number of years! 

A government grant of £5000 is applicable for eligible homes from April 2022. We’re yet to find out the exact details of the grant, but get in touch with us today and discuss whether you can qualify for the boiler replacement grant and save £5,000 towards the cost of your air source heat pump installation.
