Solar-Powered Pool Heating Rings

The floating rings gather and amplify sunlight to raise the temperature of the pool by 3°-4° F per week when covering just 70% of the surface.

Rated at 21,000 BTUs, each ring also acts as a partial barrier, helping to slow evaporation of water and chemicals, in addition to reducing heat loss at night. They require less effort to maneuver than everyday covers, and are connected by low-strength magnet s that quickly and easily separate. The inner chamber of each ring inflates with two breaths and the outer chamber should be inflated until firm. Hammacher (13/05)
