Solar pool heater |
September 16, 1980 |
| 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 wat |
