ABSTRACT:
A combined solar water heating device and storage tank for low cost solar hot water heaters is disclosed, consisting of an insulated open-topped tank in which is introduced a volume of water at atmospheric pressure to be heated by solar radiation entering through the open top of the tank. A transparent cover extends over the open top of the tank and acts to trap long wavelength reradiation from the heated water, such as to insulate the volume of heated water by preventing radiant heat loss. A pivotal reflector-insulator panel is also positioned over the tank opening which is alternately placed in an open position, in which it allows the entrance of solar radiation which is maximized by a reflectorized undersurface of the panel; and a closed position, in which it serves to insulate the heated water. The position of the pivotal reflector-insulator panel is optionally controlled by a radiation sensor to open and close the panel under varying conditions of solar radiation. The water level within the tank is also varied by a variably positioned float valve, causing additional water to be introduced into the tank as the temperature of the water increases. A channel arrangement is also incorporated interposed between the inlet and outlet to the tank insuring proper heating of the water prior to its withdrawal at the tank outlet.
