ABSTRACT:
A cast fireplace comprising a heat exchanger as the rear wall component. The side walls, sloping top, and bottom plate are constructed of precast, refractory cement panels with the rear wall comprising a metal heat exchanger. Suitable ducting combined with a blower circulates air from the room through the heat exchanger and exhausts the heated air into the room to be heated. The efficiency of the fireplace is substantially enhanced by the combination extracting heat from the fire and projecting it into the room. The heat exchanger may be incorporated in the conventional brick fireplace; however, in the preferred embodiment precast, refractory cement slabs are utilized in the construction.
