The Solar Sun Ring is a passive solar swimming pool heating device made from two sheets of heavyweight U.V. resistant vinyl. The upper clear layer holds insulating air and focuses sunlight on the blue colored lower layer.
The blue layer absorbs about 50% of the sunlight and converts it to heat. The balance of the sunlight is allowed to pass through for deep water heating. Each solar sun ring generates 21,000 BTU per day. The five foot diameter of each ring also allows for easy cleaning.
How Do Solar Sun Rings Work?
At night the contained air acts as an insulating blanket to retain heat gained during daylight. Solar Sun Rings were designed for easy placement and removal by one person. Six magnets help condition the water in your pool by improving clarity and decreasing hardness and are placed into the perimeter of each ring to facilitate rafting. The strength of the magnets will permit single position removal but will easily separate to prevent entrapment in accidental falls.Solar Sun Rings are compatible with automatic pool cleaners. If the suction hose catches on a ring, the ring will separate from the raft to allow the pool cleaner to continue. Once the water in your pool has reached adequate temperature, Solar Sun Rings may be turned over to conserve water by limiting evaporation without significantly heating the water.
Your pool requires some direct sunlight and open water to stay healthy. The open water around the raft of Solar Sun Rings and the triangle caused by the convergence of three Solar Sun Rings is by design. These open areas allow your pool to receive some direct sunlight. This direct sunlight will greatly reduce the incidence of mustard algae.
Solar Sun Rings are a perfect choice for use with solar panel systems, like the Fafco SunSaver, using the sun’s energy during the day then providing great nighttime insulation.
