No need to wind and re-wind solar blankets to keep your pool warm! Each patented Solar Sun Ring has been proven to provide 21,000 BTU per day*. Simply inflate each solar sun ring and place in your pool to keep it warm.
The patented 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.
The manufacturer of the Solar Sun Rings recommends that once the Solar Sun Rings are inflated, 60% to 70% of the surface of your pool should be covered with the Solar Sun Rings for efficient thermal heating and retention. For shallow pools and pools in colder climates, up to 80% may be covered.
Solar Sun Rings may be used on all chlorine or salt water system pools in above ground and inground swimming pools. Solar Sun Rings each measure 60" in diameter. Choose from solid blue or printed palm tree pattern.
*It has been proven that each Solar Sun Ring generates 21,000 BTU per day. In an ongoing test at the National Pool Industry Research Center at California Polytechnic University, San Louis Obispo during the summer months of 2005, Solar Sun Rings proved a total heat input to test pools of 21,000 BTU per day for each unit. This result was validated by repeatedly heating 10' x 19' test pools to a maximum of eight degrees Fahrenheit. Approximately 67% of each test pool was covered with Solar Sun Rings.
