ABSTRACT:
A heat transfer and conditioning unit includes a casing overlying a fire chamber. An exhaust conduit is disposed within said casing inwardly of its walls having an inlet to receive heated exhaust gases and an outlet adapted to communicate with a flue to atmosphere. The exhaust conduit includes a series of pairs of opposed parallel laterally elongated plates. Inwardly directed opposed V-formed plates interconnect adjacent plates to define a series of longitudinally spaced laterally elongated venturi passages along the length of said exhaust conduit. Said venturi passages effectively slow down the movement of the products of combustion through the exhaust conduit for increased quantities of heat transfer to the walls thereof. The walls of said exhaust conduit are spaced from the casing to define an independent fresh air heating chamber along the walls of said casing and exhaust conduit for the conductive transfer of heat to the forced fresh air passing therethrough.
