I have a Potterton Combi 100 boiler which heats my hot water and central heating. I have a gas fire in a proper fireplace (ie with chimney) which i dont like. I was wondering if i was to convert it to a wood burning fire with a back boiler to heat my central heating would i need any modifications to the existing combi boiler / piping system? Thanks

Yes, but it involves quite a lot of complicated plumbing including pressure relief valves.If it is not done properly you could end up with steam instead of water in your pipes and a very expensive and dangerous situation.
fraid its very complicated as your heating at the moment is sealed and your solid fuel must be open vented so no you cant , also you dont have stored hot water so all your fire could do is the rad system . because as such there is no control of the heat emmitted from a solid fuel fire you cannot just switch it off or should i say the stats will not switch it off ,the water inside just keeps on heating , heat water up when its sealed = more pressure , all sealed heating systems have to have a high limit stat on them so that if somthing fails like a stat the high limit stat kicks in and cuts off the power , it then has to be manually reset and the fault rectified . im afraid the guy that decided you should use a dunsley nutralizer doesnt know what hes talking about as its an open vented arrangement , if you fit releif valves all they will do if let out water or steam when your fire is going so NO YOU CANT LINK THEM TOGETHER
