A device and method for burning wood for the purpose of heat generation is disclosed. The device has a flat grate on which the fuel is placed and a vertical combustion air inlet passage which discharges the air as a wide, flat ribbon at one end of the combustion chamber substantially at the top surface of the grate. Combustion is confined to a zone which progressively moves along the grate away from the air unit. The combustion gases are collected at the top of the combustion chamber which is arched and arranged to cause them to spiral and while still in the combustion chamber and at autogenic temperature to mix with additional, partially heated air to complete the combustion process. The exhaust route for the combustion gases is elongated and doubled back upon itself to delay discharge and allow sufficient time to effectively heat exchange with the thermal energy transport and distribution medium.
