I received quotes from Ice Energy yesterday for the heating system. Interesting reading – they put plenty of details in which gives some confidence that they know what they’re doing and that they’ve done it before. They’ve recommended 2 heat pumps for some reason which I hope will become clear when I quiz them. The sums are quite eye-watering and I must admit a bit confusing. They price for the kit (pumps, piping, underfloor heating etc) and another price for installation. It’s not clear whether or not this includes digging the trenches for the ground source pipe work, and there are other pieces of work that they expect your main contractors to undertake.
There appear to be grants available (£3k for two heat pumps) as well as what appear to be generous government payments as part of the Renewable Heat Incentive Scheme (RHI). No doubt there will be schemes to borrow the capital required with government paybacks as your security.
