Abstract: A circulating air wood burning heating stove/fireplace combination has a combustion chamber that is in the form of a shell defined by inner walls of the stove and a rearwardly disposed air outlet manifold. Spaced outer auxiliary back and top walls and the corresponding shell walls form therebetween air passages through which ambient air is recirculated into the room over the manifold. The manifold is provided with a plurality of spaced heat conductive metal strips disposed about its periphery. Several manifold embodiments include one or more finned air heating conduits which extend therethrough. A blower fan or pair of blower fans are used to circulate air through the air passages and in heat transfer relationship to the manifold. A valve, damper, and linkage control arrangement regulate the heat output and may be used upon starting of the fire to clear a column of cold air from the flue.

Abstract: A circulating air wood burning heating stove/fireplace combination has a combustion chamber for burning fuel. The combustion chamber is in the form of a shell defined by inner walls of the stove and a rearwardly disposed air outlet manifold. Spaced outer auxiliary back and top walls and the corresponding shell walls form therebetween air passages through which ambient air is recirculated into the room over the manifold. The manifold is provided with a plurality of spaced heat conductive metal strips disposed about its periphery. An air inlet is provided at the bottom of the back air passage and an electric fan or blower is attached to the inlet to force air into the back air passage.
