You are lucky with the ten years supply of wood although it does burn quickly. I have just paid 200francs for un stere(a cubic metre) for my "insert" wood burner, so ten years supply is probably worth a lot of dosh. Can't help with the heaqter though, inless it is un insert wood burning stove. Mine has a glass door and is fitted inside the chimney breast hence insert. It has a heat exchanger over which the flue gases go and a two speed fan to blow warm air into the room. Very cosy. Roger
