ABSTRACT:
A fireplace furnace heating system for a structure having a firebox for combustion of fuel, preferably coal. A heating unit is disposed proximately to, and preferably surrounds the firebox. Conduits carry interior air from remote locations to the heating unit. The heating unit is preferably a multi-walled, chambered structure to define numerous air passageways. Air delivered from the conduits to the heating unit must travel through the air passageways. The proximate disposition of the heating unit to the firebox heats the heating unit and the air travelling therethrough. The heating unit has vents for returning the heated air to the interior of the structure. A blower is included for forcible moving the air through the heating unit and back to the interior. Conduits are also provided for supplying fresh air from the exterior to the firebox to fully combust fuel in the firebox. A motorized blower is included to forcibly move the combustion air. Also included is a tempering tank for storing water. The tank has piping for carrying water from the tank to the firebox where it is heated by a fire in the firebox. The heated water is returned to the tempering tank and withdrawn when needed through the structures hot water plumbing system.
