We looked at installing an air source heatpump, would have cost
£13k toÂ* upgrade our existing wet system.
I get the distinct impression that the government are banning existing
CH systems (as with ways of generating electricity) before they have
got a replacement that is at least as good. Replacing with something
worse is worthy of the strongest possible contempt.

I suppose modern houses can at least be insulated better than existing
houses are.


(*) I presume it does, since you say that it replaces your wet system.

Have a look at the suppliers sites for detail. A friend installed one in
a Suffolk newbuild (there was a Harry payment:-). Piped underfloor
because you don't get a very high output temperature.
Array of fans at the side of the house. I think there are location
restrictions because of noise/neighbours.
I don't know how the DHW works. Perhaps a second stage heat pump. She
seems happy with it but the house is now on the market:-)

DHW uses heatpump as preheater then immersion.
