Abstract
A supplementary heat and air supply system for a building includes a solar panel mounted to the exterior of the building, and a solar panel duct extending between the solar panel and the return air manifold of the building's conventional heating system. A fan or blower is positioned within the solar panel duct. The solar panel has a fresh air intake to provide fresh outdoor air to the interior of the solar panel. During daytime hours, when the temperature of air within the solar panel attains a predetermined level, the blower is operated to supply the heated air to the interior of the structure through the solar panel duct, with the heated air being supplied through the return air manifold. When the building's furnace operates, it draws air from the return air manifold, which also acts to draw air from the solar panel through the solar panel duct. The system acts to pressurize the building's interior during operation of the blower, to deter seepage of gases, such as radon, into the building's interior. When the blower is not operating and the furnace is operating, the furnace draws air from the solar panel along with the indoor air. This additionally reduces the amount of pressure drop in the building interior, to again deter seepage of gases into the building.
