Solid fuel fire with back boiler
I think the above exists. if so how would you tap it into the central heating system so that it will heat the rads andf hot water while your using the fire.

What controls would you use and when heating and hot water are up to temp would it just circulate round the primarys.

Its just an idea for when I buy a new house.

Yes many versions of this exist, it's a bit complicated to make it work with a conventional system but it can be done, don't expect it to be cheap though

Thanks for getting back to me Muggles.

It wont be cheap but I am a heating engineer/installer so that will cut alot of the cost. I just need to get my head round doing a proper job that works efficiantly and safely

Look at Dunsley Neutralisers. It's notifiable work to install a solid fuel fire though so you need to be qualified to do it

I realise this mate. that'll be the next issue. I can do most of the work myself but the fire bit. I'm sure I'll be able to make it as cheap as possible even if it means I have to do the course my self.

Waste of time and money. All the heat goes up the chimney.
Save your money and buy more insulation.

To comply with Part L you must fit a lot of controls which in turn try to control something that cannot be fully controlled and therein is todays problem with SF/CH and the reason most plumbers have now stopped installing it.
My advice is don't bother with it because it belongs in the past!
servotech,

You have to store the excess heat (thermal storage) or dissipate the heat (chuck it away) traditionally by boiling the water and blowing steam into the air.

The modern wood pellet or wood chip boilers are controllable and the fuel supply can be turned off. I'm not up to date on the situation with RFIs, but HMG were planning to pay per kW for installed capacity. A seriously expensive installation compared to mains gas, since all the suppliers jacked up their prices to relieve the customers of the RFI payments. Such is life.

I looked into this a while back but wouldn't be able to route the pipes - i thought they were banned as there were a couple of fatalities. Friends of mine in Cardiff don't have any CH radiators - just an open fire and back boiler. But i think the houses were designed for it. The fire is on an inside wall and heats the whole house perfectly - despite the widespread claim that an open fire is inefficient. But a back boiler won't have enough heat to give to even a couple of radiators. Other friends of mine have had a stove installed and theirs doesn't heat the rads despite what the sellers claimed. Each rad needs 1.5-2.0 KW so few stoves are able to provide the necessary heat to them.

I had a 25 or 30 ins immersion element installed and that does all the DW adequately for use between April and October [or whenever the cold weather starts and the CH goes on] - i use a 24hr timer on the plug which works very well.

tbh enjoy your open fire and use the immersion (only 20 each).
