We have been looking at multifuel stoves- burn wood/pellet/coal which has back boiler. At the moment we have no heating what so ever in our house and we are trying to get it right from the outset. After reading various comments on the forum, the general consensus seems to be that pellet seems to be the cheapest form of heating and the cleanest. The information with the stove advertised on the internet states it can heat 35 litre back boiler and can run radiators , water output 19kw. Can anyone give us an idea how many radiators this would run if radiators was roughly 2ft x 2ft. Any help would be much appreciated.
