A solar pool heater is defined by a submersible tubular ring attached to the perimeter of a floating sheet. The ring is perforated to permit the entry of water within the ring to induce at least partial submersion. The submersed ring prevents overlapping of adjacent heaters and reduces the likelihood of the heaters being blown off the pool by wind. The sheet includes a plurality of captive air bubbles to provide a floatationcapability while simultaneously insulating the water surface from the ambient air. By developing the sheet from material transparent to at least a spectrum of the solar rays, the underlying water will become heated by the received radiant energy.
