[QUOTE="Rattie, post: 7222727, member: 44122"] Latest ASHP systems are almost silent. I fitted an 11kw Mitsubishi pump with 300L solar thermal ready cylinder along with all the pumps for underfloor heating, instant hot water (some long runs, would have taken 30-40 seconds to draw hot water in distant bathroons) etc for under £6k. Pays rhi of just over 10k, so rhi also payed for UFH work and givlon screed over 140m². The equivalent GSHP was best quote at £19k if I payed for and installed the 400m of pipe in the field next to the house, (23k total approx) for an rhi payment of £15k, plus cost of UFH and Screed at a cost of £4000 fitted. [ATTACH type="full"]918956[/ATTACH] ASHP doing just over 3 COP after a year, with no issues so far, I think GSHP would need to have done well over 5 COP to compare, which was highly unlikely. I figured £12k would pay for a lot of running costs over 20 odd years. [/QUOTE]
