HughF Posted October 21, 2023 Share Posted October 21, 2023 Just done a retrofit in our 100m2 end of terrace, 1946 build, replaced a 40yr old baxi back boiler with single panel rads. Sized the rads for 45deg@-4, so far so good. We’re upgrading the windows to 3G, insulating the suspended floors and doing some IWI on some troublesome walls. Early days yet but so far so good. Should work out a bit cheaper than gas I expect, as we were running about 65% efficient before on the old back boiler. Link to comment Share on other sites More sharing options...
graham1 Posted October 23, 2023 Share Posted October 23, 2023 We live in a 1940s 3 bed farm cottage. My ASHP more than heats the house if we let it do so and as far as DHW is concerned it will produce water too hot to use without mixing cold with it Link to comment Share on other sites More sharing options...

Are you well insulated / draught free? Link to comment Share on other sites More sharing options...
