Warm your pool with free heat from the sun and cut down on evaporation. Order Solar Sun Rings online and set them out yourself, no installer needed.
Solar Sun Rings float on the water and turn sunlight into heat during the day, then help hold that warmth in overnight. The manufacturer rates each ring at about 21,000 BTUs of heat per day. Six magnets let the rings link together across the surface, and they separate easily if an automatic cleaner hose catches one.
Plan to cover about 70–80% of the water’s surface. A 16′ x 32′ in-ground pool takes about 10 rings, and an 18′ round above-ground pool about 7. The full sizing chart is on the Solar Sun Rings product page.
Covering most of the surface slows evaporation, so you add less water and lose fewer chemicals. Sun Rings work in chlorine and saltwater pools, above-ground or in-ground, and carry a two-year manufacturer warranty. They aren’t recommended for high-wind areas.
Sun Rings are one option. See how they compare with bubble (solar) blankets, mesh safety covers and automatic covers in our pool evaporation covers comparison.
Sun Rings are for heat and evaporation, not safety. For a cover that adds an extra layer of protection, see our pool covers guide. Mesh and automatic safety covers are professionally installed by an independent local installer.
