ABSTRACT OF THE DISCLOSURE A high energy saving heat exchanger is provided for the hot exhaust gases of a furnace which has a combustion chamber, a burner with electrical controls, a furnace heat exchanger and an exhaust pipe adapted for connection with a stack. The high energy saving heat exchanger includes a housing having an air chamber with an exhaust inlet connected to said furnace exhaust pipe and an exhaust outlet. An exhaust conduit interconnects said housing exhaust outlet in stack. A continuous circuitous tubing is nested within the air chamber of said housing and one end connected to said exhaust inlet and at its other end connected to said exhaust outlet. An exhaust fan is interposed in said exhaust conduit for drawing exhaust gases through said heat exchanger tubing delivering said gases under pressure to said stack. A hot air duct is interposed between said housing and a floor surface defining an area to be heated and including a hot air register. A heat duct communicates with said air chamber. A motor-operated blower is mounted on said housing and has a room air intake communicating with said air chamber for forcing room air through said housing and into contact with said circuitous exhaust tubing and for delivering through said hot air duct. An outside pressure conduit has an air intake extending through the building outside wall and an outlet which extends into the combustion chamber. A normally closed motor-operated damper is disposed within said fresh air conduit whereby upon energization of said burner said damper is open, said air blower activated and said exhaust fan energized.
