ABSTRACT:
Solar heating, especially the use of solar heating to reduce oil and gas consumption in conventional forced air heating systems of the type having supply and return ducts. During daylight hours, solar heated air is circulated as a heating supplement or substitute for furnace heated air in the existing forced air supply ducts. At night the solar heat collecting panel is shut off from the furnace system and electric resistance heated air is circulated to the exclusion of oil and gas consumption. The method is distinguished in its use of solar heat during sunny daylight hours and the use of electric resistance heating at night when existing electric generating and transmission facilities are under utilized.
