ABSTRACT:
A fireplace heater includes a metal firebox with a small chimney and front access and draft openings, the former being closed by glass doors. A sheet metal jacket with an open front surrounds the walls of the firebox to provide air conducting spaces between the firebox and jacket. Air baffles extend between the opposite sidewalls of the firebox and jacket to subdivide the air space into interconnected cold air intake passages below the baffle and a warm air discharge passage above the baffle. The interior of the firebox includes a series of baffles designed to retain heat within the firebox and promote the transfer of heat through the firebox walls into the air passages. Air diverters are also provided along the periphery of the firebox access opening for diverting draft air across the inside of the glass access doors to keep smoke from clouding the glass. A decorative grille front covers the jacket air intake and discharge openings and extends beyond the jacket to also cover the fireplace opening. Room air passes through the grillework into the jacket but is blocked from entering the fireplace opening beyond the jacket.
