its not going to be that amount and its pretty difficult to fit a wood stove into a flat its just not possibleIt's like everything else...it's not what we do, it's the 6 billion doing it.
theres many houses that have been built with just a gas liner chimney
the same can be said for those people that have taken out there chimneys just for more room we dont need the chimney as we have a gas boiler the same is said for those that pulled out there emmersion heaters for the same reason more room and no longer needed as we have direct flow to the taps

Alright then 5.8 billion.....
Something shouldnt be ruled out just because not every single person can do it. For example the powers that be just about worship air source heat pumps as their preferred solution, but there's simply not enough electricity for the 30 million odd UK homes currently using gas or oil.It's like everything else...it's not what we do, it's the 6 billion doing it.

Air source heat pumps aren't suitable for many houses either. Ours has one and it should never have been fitted, it's worse than useless.

Glad I turned the LA's offer to install one in my house. Besides the upheaval, I didn't believe the Contractor's assurances of how little mess there'd be, nor the timescale for the job.
I also understand they're not very efficient/economical when the ambient temperature is really low?

They lose efficiency in very cold weather but they still work. Just that they need very well insulated houses with appropriately bigger radiators as they are cooler than normal radiators at 40⁰ rather than the 80 or 90 I'd expect from a boiler. In our house that equates to it running flat out and costing a fortune because the heat is bleeding out everywhere before it does anything useful.

You could feed the heat exchanger with heated air from a small log fire?

Low temps aren't the issue working in the cryo industry and using Kelvin zero as -273C anything warmer than that has heat....the problem is the design of the units and refrigerant used. The gound heat is probably the biggest upheaval? Air heat is probably harder to get sufficient therms?
I wait for a rebuttal and ritual humilation from one of our resident experts.

That wasn't the essence of my comment. It was the concern about the source and quantity of non-fossil combustibles.
Like in the days of wooden ship bulding. Ports were major yards until they'd cut down all the local trees.... then it was somewhere else....Easter Island springs to mind.

Really needs to be in a modern well insulated house with underfloor heating, where the water through the loops really only needs to be 29 degrees

We and our neighbors have air source heat pumps, they are undersized for the property and as such are not efficient, we don't even turn ours on and haven't used it in about 7 years.
Our neighbor came round one day a few winters ago with heating problems, I went to have a look and there was a huge ice cube where his external unit sat. Totally solid block of ice! We came to the conclusion that was why it wasn't working! He ended up having to go and buy a load of electric heaters.
Our whole house is heated from a 7kw multifuel stove, very well!
All my wood is either free or costs me the running of the chainsaws, most is dead standing that I and my brother have removed, and all of it is locally sourced.
Can't get much greener!
(apart from a rocket stove)
Having said that, I have been involved in projects where they have been sized correctly and worked brilliantly, did a modern well insulated huge place that had all underfloor heating, customer couldn't have been happier!

Pre 60s houses were single glazed and loft insulation was unheard of. Houses were basically built to keep rain and wind out. Heat was a secondary consideration. Wasn't much difference between outside and inside temperatures. My fish tank on the window sill froze solid and the fish were in suspended animation. Lit the open coal fire and they thawed out and swam around unharmed.
Worst August on record.

Ah yes, I forgot to mention the underfloor central heating...that our house also doesn't have!
Re water storage tanks... i put a thermal store in last year. Rayburn and oilnboiler are plumbed up to it and is has inputs for solar water, immersion and the log burner should we so wish. Oil boiler does not get switched on in winter and the rayburn keeps the house at 21c plus. I think.our setup suits our 200+ yr old cottage perfectly... not sure an ASHP would be suitable even if I wanted one.

How many gallons of water do you store ?
I think the issue maybe the temperature difference. The specs I've seen for ASHPs have been for outside air at 7°C and heating circuit 35° flow 30° return. I've not seen straight answers about performance when outside air is significantly below zero. For example last December there was a day when the highest temperature was -6°.Low temps aren't the issue working in the cryo industry and using Kelvin zero as -273C anything warmer than that has heat....the problem is the design of the units and refrigerant used. The gound heat is probably the biggest upheaval? Air heat is probably harder to get sufficient therms?

Yea weve a heat store too, heated by oil or the back boiler in our multi fuel stove, but there also good addition to any UF system especially an ASHP.
Round here there are 8 shall we call them pensioners bungalows, housing association pushed them from fires with back boilers to air source……..one refused and replaced fire with modern multi fuel with back boilers, paid for himself. Their only insulation is in the loft and oldish double glazing.
7 have large leccy bills and are always moaning of the cold, ones snug and quite smug.
This tells me what the makers think about ASHPs, only real issue is the price
