ABSTRACT:
A solar pool heater is defined by a submersible tubular ring attached to the perimeter of a transparent or translucent sheet. Floatation of the heater is obtained through an air bubble captured by the sheet and maintained by the ring. The ring is perforated to permit the entry of water within the ring to induce partial submersion and thereby establish a peripheral seal about the captured air bubble. The submersed ring also prevents overlapping of adjacent heaters and reduces the likelihood of the heaters being blown off the pool by wind. By developing the sheet from material transparent to at least a spectrum of the solar rays, the air space intermediate the sheet and the underlying water surface will provide a "greenhouse" effect to heat the water through direct impingement by the received radiant energy; additionally, radiation of heat from the water will be reduced by the sheet, whereby, the heater not only collects but retains the impinged radiant energy.
