Franchina, A

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 is disclosed. 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 heated 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 pass the evaporator for permitting the recapture of stack heat for heating the building. The heating system includes a solar panel for heating air passed therethrough and a circuit for using the solar warmed air to warm the ambient air at the evaporator. A heat storage chamber is provided wherein air warmed by the solar panel may be stored for future use when the amount of solar warm air available exceeds the amount needed for heating the building.
