ABSTRACT:
An inexpensive, easy to use and to store, solar pool heater which comprises a flexible corrugated plastic sheet having one side thereof matte black and the other side thereof white in color and tubular plastic floats removeably secured to two edges of said sheet and suspending said sheet a short distance below the surface of the water of a pool when said sheet and floats are placed therein. During daylight hours, the sheet is positioned with the black, heat absorbing surface upwards and then, at night, the sheet may be reversed with the white surface uppermost to minimize heat loss from the water. The sheet is relatively small, e.g. 1 meter square, and in use, multiple sheets and floats are interconnected to give the desired coverage to the pool surface. Being small in area, the sheets may be removed from the pool and stored in a small space as by hanging from the wall of the pool enclosure. The submerged corrugations provide considerably more heat transfer surface than can be achieved by a smooth surface such as a film.
