ABSTRACT:
The device of this invention is an enclosed firebox constructed to fit in a wall fireplace cavity such that the front piece of the enclosed firebox faces the room interior while the back piece faces the outdoors. The front piece contains duct openings to emit heated air from within the firebox into the room. The openings can be closed off to prevent air flow from either into or out of the room. The heated air is obtained from air outside the room to be heated.
