ABSTRACT:
A device for converting an existing fireplace to an efficient space heater to fully utilize the heat generated by a fire therein without losing the aesthetic effect thereof is disclosed. The device includes a plenum chamber adapted to rest on the bottom surface of the fireplace, said chamber having a damper controlled draft inlet opening into the existing ash dump pit. The ash pit then serves as an air inlet conduit for air to be heated, and outside air may be supplied thereto by a fan. Pipes extend from the interior three edge portions of the chamber upwardly and around the fire wall and terminate framing the upper and side portions of the fireplace opening. A conventional fire grate is disposed on the upper surface of the chamber surrounded on three sides by said pipes. Air admitted to the plenum chamber then circulates through the pipes to be heated by a fire on the grate, and is then expelled into the room. The outlet openings for the pipes may be contained within a frame surrounding the fireplace opening which also mounts conventional glass doors.
