Fireplace furnace with heat exchange tubes
A wood-burning furnace unit for insertion in an existing fireplace includes a metal firebox surrounded at its opposite sides, top and back in spaced relationship by a metal jacket to define an airspace between the jacket and firebox wall and air inlet openings into said airspace at the opposite sides of said firebox. The firebox has a front opening closed by glass doors and adjustable draft openings below such doors. Air blowers within the jacket at opposite sides of the firebox draw room air into the jacket and blow it rearwardly into heat exchange tubes which pass through the firebox from the back of the jacket airspace and discharge heated air back into the room from the front of the firebox. Baffling within the jacket distributes the room air to the various tubes. In one embodiment, there are both upper heat exchange tubes passing through an upper portion of the firebox and lower heat exchange tubes passing through a lower portion of the firebox. In a second embodiment, only the upper tubes are used.
