Fireplace furnace
A fireplace furnace is insertable as a unit into the front opening of an existing fireplace. It has a firebox portion and can also have a cookstove extension of the firebox which protrudes into the room when the firebox is positioned in a fireplace. A sheet metal jacket around the firebox encloses a first air space. Double side walls of the firebox define a second air space. Frontal air openings connect both air spaces to the ambient room air. Rear openings in the outermost side walls interconnect the two air spaces at the rear of the firebox. Heat exchange tubes communicating with the first air space at the back of the firebox pass through the firebox to air discharge openings at the front of the unit. Air intake blowers in the first air space are insulated from the firebox by the second air space. Baffles in the first air space direct the incoming air flow rearwardly along the outer side walls, deflect a portion of such flow into the second air space, and divide another portion of such flow approximately equally among the heat exchange tubes. The unit has a front access opening and door with adjustable draft control mechanism.
