New system - boilder/Solar/Woodburner linked to Heating/UFH/

[wertert]

All



I have been trying to get my head around the idea of linking a wood burner into a central heating and hot water system. We are building an extension onto our house and it will have an entirely new heating system. The extension is 3 storey with kitchen/utility on the ground floor and bathrooms on the top floor.

Our original plan (pre wood burner) was a standard pressurised cylinder fed by a system boiler located on the GF. The boiler would also feed the under floor heating and 16 radiators



Ground Floor: pressurised cylinder / boiler / UFH manifold / 6 rads / kitchen / Bathroom


First Floor : 6 rads / WC




Second Floor 4 rads and bathroom


We will have an attic space above the second floor which currently will be unused.


We have since added a wood burner into the equation on the ground floor and we have access to alot of firewood. I would really like to link the wood burner into the heating system so it can contribute to the hot water / Under floor and Rads.



I found a number of posts covering various methods and to be honest I am really confused. One thing that keeps coming up is you should not link a wood burner to a pressurised system so I'm thinking that our original design is out.



Saying that … I found this… http://www.h2panel.co.uk/h2layout_5.htm. So how come this is possible ?



I think i'm either looking at a h2panel or a heatstore arrangement. I've read some great things about the h2panel so this seems a good/cost effective option. It seems you need a specialist to install a correctly setup heatstore ?



So my question to you experts is what would you do ? I obviously don't want to spend £££ much more than the original system as I now also have to buy a wood burner

and have the chimney flued etc.



The wood burner has to go on the GF but as nothing else has been purchased / installed yet I am really open to options. The UFH has been partially installed on the GF so the UFH manifold will have to go in the utility room. Probably should think about Solar connection for the future. i.e install pipe work now.

Any help would be great as I’m meeting my plumber on Saturday to discuss ideas as this is definately out of my league....

Hi

Didn't end up linking together. Probably a good move as

1) We don't use the wood burner very often i.e only weekends so the expense integrating heating etc off the stove would probably not have been worth it.

2) Solar hotwater is installed but actually quite rubbish at the end of the day. Mainly because panels are only south-west facing ( south not available ) and we've had rubbish weather since they've been installed. Also 20m round trip between panel and tank doesn't help. I'm using it as pre-heat for the HW tank. Boilder kicks in at 18:00ish and completes the job. I reckon we've had 4/5 days in the last 18 months where the boiler has not needed to contribute.

3) UFH is under wooden floorboards and as they are an insulator doesn't really heat the room very well. In cold weather we need to switch on the rads as well.
