ABSTRACT:
Solar heating apparatus that includes a solar panel having a generally rectangular box type frame that is open at the front, glass panes mounted on the frame to close the front opening and provide a dead air space, a plurality of horizontally elongated, generally rectangular tubular channels mounted with the top wall of a lower channel in abutting relationship with the bottom wall of the next higher channel, a water inlet opening through one end of the uppermost channel, a water outlet opening through one end of the lowermost channel, conduits interconnecting the channels to provide a liquid flow path serially through the channels from the uppermost channel to the lowermost channel, a heat storage reservoir, lines including a pump for pumping liquid from a heat exchanger in the storage reservoir to the panel inlet and return the liquid from the outlet to the heat exchanger, control mechanism for operating the pump in response to temperature changes in the panel, and a heat transfer system for transferring heat from the reservoir to a room or other facility to be heated. The rate of liquid flow through the panel is controlled so that only the lower portion of each channel contains liquid, for example water.
