Heating from thin air?
It almost seems too good to be true, but air source heat pumps do exactly this. Using a large fan-style device that is placed at the back or the side of your house, these heat pumps extract heat from the ambient air. After going through a very similar compressor system to ground source heat pumps, this can then be pumped around your home in the same manner as conventional heating elements.
The Renewable Heat Incentive
First announced in 2008 and effective from 2014, this governmental incentive is aimed at promoting a transition towards renewable heat sources. Currently, the incentive is due to end for new applicants on the 31st of March 2022, however pre-existing claims won’t be affected by this. It has a commercial element too, but we’ll focus on the domestic aspect here. The incentive provides funding for both ground source and air source heat pumps which continue for seven years from the date of the first payment. The amount that you’re paid corresponds to the kilowatt hours of renewable heat that your system produces. Although this makes it difficult to estimate the funding available from the renewable heat incentive, for ground source it’s estimated to return between £20,000 and £30,000 although this is extremely variable depending on house size and insulation.

Figures for comparison
|Ground Source Heat Pumps||Air Source Heat Pumps|
|Effective all year as the ground temperature maintains a steady temperature of around 10 degrees throughout winter||Effective in temperatures up to -15c, however the efficiency level decreases as the temperature drops|
|Installation cost – £10,000 – £18,000 (a large part of this is digging the necessary trenches)||Installation cost – £6,000 – £8,000|
|Design life span of around 40 years||Expected life span of 10 years|
|RHI up to £4,573 a year for 7 years||RHI up to £1,348 a year for 7 years|
|350% efficiency compared to about 90% efficiency of a boiler|
|No emissions released on-site|
|Requires minimal maintenance|
