Workman, T W

A safe, practical and inexpensive method is disclosed for saving heat units on modern forced warm air heating furnaces. This method employs a heat exchanger designed by the furnace manufacturer to fit each different size and type of their models. The heat exchanger is interposed directly on the furnace heat exchanger outlet and on through the piping to the flue or chimney. Air circulation through the heat exchanger is provided by the furnace blower by directing air from the warm air supply plenum, with its positive pressure, through the heat exchanger and terminating in separate supply run with a high volume of air which requires no external power to accomplish it. The heat exchanger will be provided with test openings for thermometer readings at the inlet and outlet of flue gas travel through the exchanger. A manual damper may be locked into proper position to restrict air circulation flow if necessary to maintain proper flue gas exit temperature. A down draft divertor or barometric shall be placed into proper position between the secondary heat exchange and the flue or chimney.
