Are ground source systems environmentally friendly?

Yes. In the UK, there is now a strong move towards alternative technologies that are sustainable and environmentally friendly. 40% of CO₂ emissions are derived from the heating and cooling of buildings. Using heat pumps to transfer heat into buildings reduces carbon emissions radically, when compared to burning fuels. The arguments are even stronger where a building needs cooling in summer as well as heating in winter. Ground source heating and cooling provides sustainable energy by recycling heat between seasons.

The rapid decarbonisation of the grid means that well designed heat pump installations release much lower carbon emissions from the power stations than combustion boilers do on site.
