Wood burner in place of a back boiler

I seen a solar roof system. Wood burner with water heater. Gas combi boiler all working together.
Velux made the water system.

I think there was a tank in loft but I don't know how it all worked. Only ever seen one on new build house around 2011.
There was a cupboard with control system and lots of pipes. Was neat (edited)

I used to live in a coal miners house (on a council estate nothing specialised) that was built to heat everything just from a fireplace in the lounge. It had heat capture in the chimney so even the smoky heat was used not just the radiant immediate heat into the room. When money was low we'd just go collect dead wood that nobody else valued.
So far as I know its feasible, people have quite fancy enclosed stoves now but the main thing is to retain all the heat. Sounds like your plan could work if plumbed in.

Anyone in Scotland should be using the Solar scheme they have, I dont know why they wouldnt (edited)

Looks like it might be possible to install a log burners in a sealed central heating system, as a quick google found this :- greymetal.co.uk/ins…tml

Presumably, unless you're wood burner can be fed from an external air supply, you'd need to reinstate permanent air vents in the room, which would put me off, having put up with the cold draft for years when we had a backboiler? (edited)

Yes this install is fairly straight forward.

You would need to have defra approved stove fitted, anything upto 5kw doesn't need building certificate and doesn't require additional airflow but install does need to be signed off by hetas registered installer and submitted to local authority.

You will also want to make sure you have entire chimney swept thoroughly before stove installed, you can either have it all lined or use 5 inch stainless flue from stove to pot. If you want better thermal efficiency then a more expensive double lined flue can be used.

Not sure on your location but I had same work done and at time 2 installs with gas fire removal etc was 5200 for both which also included new hearth's being built. Think stoves at the time were £599, it's not cheap and with new Woodsure scheme putting up firewood prices, gas can be cheaper but green freak politicians be banning it soon so for us with a house the size of ours 2 fires downstairs in winter keep house really warm. And we stock up on firewood throughout the year for use through Oct to Feb. Don't use smokeless coal often as don't like the smell but nothing beats a wood burning stove in winter.

And anyone who bleats about particulate needs to go research first and not daily mail or BBC but actual unbiased studies (edited)
