ABSTRACT:
The present invention includes a heating system for use with a primary source of heat, such as a gas hot air furnace, or the like. A first conduit formed with perforations therethrough conveys hot exhaust gases generated by the furnace to a flue. A second conduit carrying a fluid is coiled about the first conduit in close proximity thereto so as to permit a transfer of heat to said fluid from exhaust gases escaping from said perforations and contacting said second conduit. A third conduit houses the first and second conduits and conveys exhaust gases that have escaped through said perforations to the flue. Sleeve means intermediate the first and second conduits control the rate of said heat transfer.
