Cant help with a fitter in your area, but I once installed one - a few pointers to watch for (ie to make sure the fitter knows what he is doing)

1. Pipes from back boiler need to be 32mm copper.

2. All pipes need to meet at a box called a Dunsley Baker Neutraliser (or system neutraliser) if the fitter says "a what" then get another fitter!

I think you will struggle to run HW & CH of a log burner, the one I fitted gave lashings of hot water with the CH system only kicking in when the water got too hot in the tank - ie it acted as a heat sink.

Thanks

Egglady -I have a double front door Hunter wood burner in our lounge which used to heat our water and radiators. It was a simple system which is pumped through our immerser tank and it gives you the option to heat up via the immerser switch in the summer.I got fed up cutting down forests to fuel it so,  I installed an oil burner, disconnected the pump and now the burner has become a radiator with the water being pumped from the oil system (although i can still use it carefully as a fire).

We have a woodburning stove/cooker (Esse ironheart) linked up via its back boiler to our hot water system.

It works well tho we havent tried to connect it to the oil fired central heating (which is mainly underfloor).

We made sure it is gravity fed not pumped, so the angles are correct for that to work, pipes wise. It means that since it also cooks, if we have a power cut we have cooking, some hot water and some heating direct from the stove!

In my experience it might be more efficient to just heat hot water with the stove and look for another way of doing the central heating as the input needs of HW and CH are very different (one needs high temp but not all the time, the other needs constant lower temps, wood stoves arent ideal for the latter).

What about solar or heat pump for heating?
