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.
Claims9
A discrete hot gas trap attachment for connection between the outlet flue of a heater in an environ space and a chimney to either vent hot flowing gases freely from said outlet flue to said chimney or to choke hot passive gases from said outlet flue to said chimney comprising an elongated horizontal housing including a base plate and a top plate connected to each other by sidewalls for defining a horizontal choke chamber, a heater connection duct depending from the lower side of said base plate for connection to said outlet flue, a chimney leg duct and a shroud portion depending from said base plate and being positioned in laterally spaced relationship to said heater connection duct, said shroud portion extending below said chimney leg duct with said shroud portion being in vertical alignment with said chimney leg duct, said shroud portion and said chimney leg duct being open to said environ space, and a chimney connection duct having its vent opening at or below said base plate and in communication with both said chimney leg duct and said shroud portion for venting said outlet flue to said chimney to vent hot flowing gases freely or for venting said environ space to said chimney to choke hot passive gases from said outlet flue.
