ABSTRACT:
A novel type of heat exchanger that pre-heats a fuel prior to being burned within a home furnace, so that the fuel burns better; the device consisting of a coiled tube running axially through a narrow pipe that extends transversely through a wide pipe, one of the pipes being located along a hot water line of the house that is used for washing, bathing and the like while the other pipe is along a house heating line such as for a baseboard hot water heating system, whereby use of either hot water line will preheat fuel moving through the coiled tube so that in effect the device forms a double heat exchanger.
