Solar Sun Rings

Solar Sun Rings Portable Above Ground Inground Swimming Pool Hot Tub Spa Heating Accessory Circular Heater Solar Cover, Blue (6 Pack)

Main Highlights

HEAT YOUR POOL - Solar Sun Rings are passive solar swimming pool heating devices, constructed from two layers of U.V. resistant vinyl. The upper clear layer directs the suns rays onto the bottom blue layer which absorbs about 50% of the sunlight, converting it to heat. The remaining sunlight filters through the ring into your pool water.
WARMING DISCS - The majority of heat loss from a pool comes from the water surface at night. Solar Sun Rings do not cover the entire surface of your pool; therefore it allows heat to escape. To help keep the warm water in your pool at night we recommend you use additional insulation such as solar fish or a solar blanket.
WHAT'S INCLUDED - Each unit contains 6 magnets that are used to attach the rings together. Do not over inflate. Do not use as a flotation device.
SOLAR ACTIVATED - Use the Solar Sun Rings to provide heat to your swimming pool from the sun. Swim comfortably without wasting energy
PLEASE NOTE - These Solar Sun Rings are NOT a solar cover or a replacement for a solar cover. These are floating disc heating devices.
