A generally cylindrical casing is hollow, and is supported by a base so that the axis of the casing axis is horizontal. A vertical partition divides the casing into a fire chamber and a smaller exhaust chamber. The smaller chamber is vented to the outside atmosphere by a chimney. The partition does not completely isolate the chambers, but enables them to be interconnected through a small gap at its bottom. Extending rearwardly along the curved portion of the casing are two oppositely disposed pa...

Recirculated air from the room is drawn in and mixed with the heated fresh air in a zone formed between the chimney hood and a decorative hood casing. A linked damper arrangement is provided with one damper on the chimney pipe to control the fire draught and one on the fresh air inlet so that the amount of fresh air admitted is proportional to the amount of air extracted from the room.

A fireplace heating unit provided with a firebox. A vertically elongated hollow member defining in horizontal cross section a square and formed primarily of transparent material, is open at both ends and is secured at its lower end to the firebox. A hollow top section having a relatively small open upper end which defines a chimney and a lower open and conforming to and engaging the upper end of said member has a narrow horizontal peripheral border having the same shape and essentially the perim...
