ABSTRACT:
An energy conserving device for preventing loss of heat energy from a heater to a chimney by means of a fluid gas heat trap to choke off either chimney draft and/or heated convectional air currents lost to the chimney when the heater is OFF but allowing combustion gasses to vent freely to the chimney when such gasses are generated. The device also acts as a diverter for either up or down drafts from the chimney to direct them away from the heater. In another form when the device is used with a forced air type furnace, the device in addition provides heat interchange between room air and the hot gasses in the trap. This then heated air is drawn into the circulating system of the furnace adding to its temperature while lowering the temperature of the vented combustion gasses, to lessen the heat loss up the chimney.
