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.
One Solar Sun Ring is inflatable and 60-inches in diameter. Each unit is equipped with six magnets that are used to attach rings together.
Solar Sun Rings may be used on all chlorine or salt water system pools and were designed to be compatible with automatic pool cleaners. Easy to install and remove!
