joining log burner into heating ?

[nicke20]

I have an old multifuel burner in my lounge, it is a coalbrookdale severn
I believe it is 14.5 kw ! it has the ability to heat water but this is not being used so essentialy it is a metal box sat inside another metal box, not great for radiant heating. I have a couple of thoughts for the summer when i dont require heating. Either join it into my current combi central heating system on a thermostaticaly controlled valve, ie when its heating water it suplements the current boiler or just run say 3 radiators off it on its own small loop
Can my first idea be done? if not are 3 radiators sufficiant?

This is not as easy as just connecting two heat sources directly together. Click here to see how to do it using a Dunsley Neutraliser. (Other neutralisers are available )

If there's a back boiler in place already and it's been dry fired it will most likely need replacing as they're not designed to be heated with no water in them

Do you have a large supply of nearly free wood to burn?

Connecting different sources of heat together really needs professional advice!

Anything with a water jacket should never be operated without water!

when i bought the house i was told that it had run radiators in the past but had been disconnected when "modern" heating was installed
and had been run for a few years without
It is all cast iron, it is either water tight and preasure safe or not but as just a log burner it is rubbish, I am trying to gather as much heat from the combustion as possible instead of letting it all go up the chimney. I have sat in a room with modern log burners that you cant get near and they are rated at a quarter of this ones heat output!!
I have fairly good supplies of wood at £40 to £50 per cubic meter of hardwood and as much free palletwood as i like

It is not possible to connect to combi system as the heating side will be high pressure and sealed.

You will need an indirect cylinder, heat sink radiator and water storage tanks ( one large for hot water and one little one for boiler and heating ).

Your log burner cannot be used on sealed system like your combi.

Using log burner without water is asking for trouble, it could warp a little, maybe made water jacket a little weak.

Indeed, sorry missed that it was a combi, so can't be connected to a vented system that a stove requires.

So, how about leaving the combi system exactly as it is, and then just adding a header tank with said vent for the stove, then pipe it up to 3 or 4 new extra radiators in the main rooms. This would save on heating costs when the stove was being used, and is a fairly straightforward installation. The only disadvantage, is that a few rooms would have two radiators instead of one.
