A wood burning heating system comprises a large hot water storage tank and a furnace or boiler with a water jacket and a vaulted ceiling over a firebox with a refractory bottom and a refractory lining partially up the side walls of the firebox. The volume of the tank is about ten to twenty times larger than the volume of the water jacket, whereby the large hot water volume acts as a heat storage and as a buffer or heat output equalizer counteracting any intermittent heat input inherent in a solid fuel system especially a wood burning system. The firebox is elongated and the door is so arranged that wood pieces of random and substantial size may be charged into the firebox so that the wood is burning while it is in a horizontal position. The large hot water storage tank may receive additional heat input, for example from an electrical heater operated by a wind driven generator. If desired, the furnace may be installed inside the large hot water storage tank. The furnace or boiler with the tanks and interconnected pipes form a connected container system having a common water level and vented to the atmosphere above said common water level whereby the system works at atmospheric pressure and the boiler cannot develop any steam pressure.
