Fireplace furnace heating system

A fireplace furnace heating system for a structure having an interior and an exterior and a plumbing system, comprising

• a firebox having plural sides, and a grate for placement and burning of combustible materials therein;
• a draft control assembly having a closable conduit from under said firebox to the exterior of the structure for supplying said firebox with fresh air for combustion;
• a chambered heating unit having at least one air input and at least one air output, plural walled sides and a plural walled back, said plural walling defining a cavity for the movement of air therein, said top of said heating unit comprising plural hollow pipes for connecting said plural walled sides, said heating unit substantially surrounding the firebox, wherein interior air flows for maximum transfer of heat from said firebox;
• at least one register mounted at a remote location within the structure interior;
• ventilation ducting connecting said at least one register to said at least one input of said heating unit for providing an air passageway from said at least one register to said heating unit;
• at least one vent communicating with said at least one output from said heating unit for outputting heated air from said heating unit to the interior of the structure;
• a return air blower having an input and an output for forcibly moving return air from said at least one register to said at least one vent, said return air blower disposed within a path defined by said at least one register, said ventilation ducting, said heating unit and said at least one vent;
• a smoke cone above said hollow pipes of said heating unit, said smoke cone having a closable outward opening in communication with the exterior of said structure for exhausting exhaust gas to the exterior, said smoke cone including an adjustable damper control for adjusting the size of said closable outward opening;
• a water storing tempering tank having a top and a bottom, a water inlet and water outlet at said top and a water inlet and outlet at said bottom;
• metal tubing encircling said firebox and attached to said firebox by heat exchanging plates, said metal tubing connecting said bottom water outlet to said top water inlet whereby colder water circulates out said bottom water outlet into said tubing where it is heated by contacting said firebox to produce heated water, said heated water flowing into the top water inlet, fresh cold water entering said tempering tank from a house supply through said bottom water inlet, hot water exiting to the structure plumbing through said top water outlet.
