Melvin, H A

A solar hot water heater includes an insulated box having one or more hot water storage tanks contained inside and further having a lid which may be opened to permit solar radiation to heat a supply of water contained within the one or more hot water storage tanks. A heat-actuated control unit is mounted on an external portion of the box, such control unit having a single pole double throw thermostat which selectively activates an electric winch gear motor to either open or close the box lid. The control unit operates to open the lid to a predetermined position when exposed to the sun's rays, and further operates to immediately close the lid in response to any sudden drop in temperature, such as might occur during a rainstorm, clouds moving in front of the sun, or the like.
