What are air source heat pumps and how do they work?

Air source heat pumps are a completely renewable way of heating your home effectively and efficiently by harvesting heat from the air outside of your home, even in winter.


Air source heat pumps essentially take the heat from the air – even if the temperature outdoors is below freezing and transfers this energy to heat the water for your home.

You will simply need an outdoor unit, which only requires electricity and water connections, this heats the water inside your home, via a hot water tank, giving you an efficient and cost-effective heating solution.

Ecodan air source heat pumps can operate in temperatures as low as -25ºC and are specifically designed to British standards for British homes, you can rest assured your system will continue to perform to a high standard, even in the height of winter. Ecodan heat pumps are manufactured right here in Britain, by the experts here at Mitsubishi Electric.


Cost of air source heat pump installation


The cost of installing an air source heat pump does vary based on the size of the system being installed, but data collected by the National Audit Office (NAO Report) found that, in 2023, the average heat pump installation cost was £11,287. That means that on average heat pump owners were paying £3,787 for a new install, after taking the Boiler Upgrade Scheme or The Home Energy Scotland Grant into account.

Further reports published by   (on behalf of UK Gov) give more detail around average cost based on property size, the findings in the report show that a fully installed heat pump requiring upgrades to the radiators are typically in the region shown in the below table.
