Solar Sun Rings
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. At night, the contained air acts as an insulating blanket to retain heat gained during daylight. There are six magnets to hold the rings loosely together for easy positioning that also help improve the clarity and decrease the hardness of the water. Each Solar Sun Ring measures 5 feet in diameter.The Benefits of using Solar Sun Rings:
