When you look at the heat pump market, air source systems have become more popular than their ground source cousin. But this hasn\u2019t always been the case. <\/p>\n

Around seven years ago, the ground source pump appeared to have won the renewable tussle. This was mainly down to the higher efficiency levels achieved over air source systems and the proven reliability of providing excellent space heating. <\/p>\n

But this comes at a cost \u2013 literally. Ground source heat pumps are more expensive to install and there\u2019s a lot more disruption, with the systems needing to be fitted into a borehole in the garden. For this reason, interest in air source pumps has increased as the installation process is much simpler and there is no need for ground works. <\/p>\n

In the middle of winter you\u2019ll probably see better efficiencies with a ground source pump though, mainly because temperatures in the ground stay at a pretty consistent heat. However, remember that air source heat pumps can still extract warmth from temperatures as low as -15 degrees Celsius. This temperature can then be increased with a compressor so it\u2019s suitable for your home. <\/p>\n

So how do the two systems compare when you look at the financial incentives?<\/p>\n

First there\u2019s the Renewable Heat Premium Payment (RHPP) grant which is available for both installations. The grants have recently been increased because of delays in the Renewable Heat Incentive.
