AHSP in Old House

[Warble]

"SmartRad"s are an alternative to UFH at lower water temperatures.

what about updating insulation, improving window  and door draught proofing
going all electric, less hassle to install, easy to operate, supplement with more PV  to offset costs.
PV with diverter for immersion for heating hot water, ditch oil, tank etc
depend is the folks can deal with the hassle with all this, some people cope better than others with having carpets lifted, floorboards up, trades, in, disruption etc.

Thank you to all who commented.
The project has been shelved. Parents are not going to live long enough for this sort of work to be worth doing (their words)

We had several companies turn up and look around. Some of which just wanted to sell an ASHP with no consideration as to whether it would work well or not. Our last visitor was brutally honest about everything and came across extremely well, knowledgeable and skilled and her advice matched what people from this forum were saying and my own inexpert opinion - that it just wasn't gonna work - not without spending a bucket load of money on insulation and other stuff as well.

Really interesting thread, thanks for asking NugentS !

I came across this Radio 4 'Costing the earth' podcast about gas boilers - there's a bit on hybrid heat pump / boilers starting at 17:00 in
