ABSTRACT:
A heating system for a building having a conventional gas furnace which includes a combustion chamber for heating air passing from a cold-air return to a hot-air duct. The gas furnace includes an exhaust stack for exhausting hot gases from the combustion chamber externally of the building. The heating system includes a heat pump comprising a housing having a condenser for heating air passing thereby from the cold-air return to the hot-air duct. The heat pump also includes an evaporator located externally of the building for drawing heat from the atmosphere. The heating system includes a conduit connecting the exhaust stack to the evaporator such that exhaust gases from the gas furnace combustion chamber will be directed past the evaporator for permitting the recapture of lost heat for heating the building.
