Abstract
A solar water heater apparatus particularly useful for stock tanks in remote locations has an open water tank, a heater floated in the tank with a portion of the heater below the water, and means for maintaining the heater location in the tank. The solar heater may have a frusto-conical support made of curved trapezoidal surfaces, coils around the support member adapted to carry anti-freeze and a number of the coils disposed below water.
Claims9
A solar water heating system for a tank subject to freezing comprising an open water tank of predetermined size adapted to have water therein at a certain level, a solar water heater substantially less in cross section than said predetermined size disposed in said tank and adapted to have a substantial area of surrounding water in said tank, said water heater comprising a frusto-conical supporting member including a series of curved trapezoidal surfaces having interfitting edges along their slant length juncture, continuous convolutions of coils wrapped around said curved trapezoidal surfaces and resting thereon for holding said series of curved trapezoidal surfaces in assembled edge interfitting relationship with the weight of said coils, said coils being adapted to contain an anti-freeze liquid to be heated, and a predetermined number of said convolutions being disposed below the surface of the water in said water tank.
A stock water heating system for a tank subject to freezing comprising an open water tank of predetermined size adapted to have water therein at a varying level, a solar water heater substantially less in cross section than said predetermined size disposed in said tank at a location therein and adapted to have a substantial area of surrounding water in said tank, means for floating said solar water heater on the surface of the water in said tank with a predetermined portion of said solar water heater being disposed below the surface of the water in said tank, and means for maintaining said solar water heater at said location in said tank irrespective of the water level therein.
