Solar Spa Ring is a passive solar spa heating device made from two sheets of heavyweight U.V. resistant vinyl. The upper clear layer focuses sunlight on the translucent 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.
