ABSTRACT:
An efficient heating unit for ready installation in any standard fireplace includes a refractory lined fire box contained within an outer shell to form a heat exchanger between hot gaseous fuel combustion products and living space air entering the jacket space between the walls of the fire box and the outer shell in a continuous convection cycle. Heated air re-enters the living space through a grill above the fire box and fire box flue maze. The flue maze or manifold forms a radiator of great surface area which projects into the living space immediately below the heated air grill and the maze is vented into the chimney by two non-adjustable and one adjustable vents which are sealed from the air passages of the heat exchanger. Lockable and adjustably vented doors at the front of the fire box are provided. A three piece face plate formed of thin metal having thermal contact with both the fire box and heat exchanger shell maximizes heat radiation into the living space.
