I’ve looked at ground heat pumps before (not air pumps). However they are a huge capital outlay of £10k-£19k ($13k-$26k). Both air and ground heat pumps work best for buildings with underfloor heating. Floors cover a much bigger area than radiators so they don’t need to get as hot to provide the same amount of heat. We’re in a 70 year old building so that doesn’t help. The savings are minimal maybe £30-£60 a year before the recent gas price increases. You can get grants of £2k per annum for 7 years so you will get money back. However they don’t really save any money unless you think gas prices will remain high. Outside of that you do it to be green. https://www.which.co.uk/reviews/ground-and-air-source-heat-pumps/article/ground-source-heat-pumps-explained/ground-source-heat-pump-costs-and-savings-aYYGN4A4NFpB https://www.which.co.uk/reviews/ground-and-air-source-heat-p...
