A heat saving conversion unit for hot water heaters of conventional type consisting of a heat exchanger attachment together with appropriate connecting apparatus provided in kit form, and the method of use thereof, which includes a stainless steel outer casing provided with inlet and outlet water connections and a heat exchange tubing structure consisting of an outer tubing of stainless steel and an inner structure of soft copper for receiving hot refrigerant gases therethrough to extract the normally wasted heat therefrom and in turn heat the water passing thereby. A feature is in the connection of this attachment to the conventional drain plug opening and popoff valve openings of the conventional type hot water heater. Furthermore, an extension tube is contained with the kit for insertion into the popoff valve opening of the tank so that the hot water from the heat exchanger attachment exits into the hot water tank lower than the upper electric heating element when the kit is used with an electric type hot water heater.
