Abstract: A wood and coal fired heating unit, comprising a magazine wherein is incorporated a preheating draft manifold, supplying all primary and secondary drafts to the combustion zone and secondary combustion chamber. Within the fuel combustion chamber a baffle, the same comprising a wall between said combustion zone and said secondary combustion chamber. The secondary combustion chamber is housed within the heater fuel combustion chamber for maximum temperature operation for completing the combustion of the unburned volatile gases leaving the primary combustion zone. With indirect primary draft in the primary combustion zone, in combination with the secondary combustion system, the invention being capable of sufficient combustion of the fuels considerably retarding formation of creosote.
