Solar Sun Rings are vinyl rings designed to passively heat outdoor swimming pools using energy from the sun. The rings are approximately 60 inches in diameter, so it will take several to cover even a small pool. However, complete coverage is not necessary--the manufacturer recommends that enough rings be purchased to cover 60 to 70 percent of the surface. The rings also inhibit evaporation, decreasing both water and chemical usage in the pool. In user product reviews, a majority of customers express satisfaction with solar rings.

On the Other: Several Drawbacks

Negative reviewers have reported several problems, including that the rings are lightweight and can blow away. Users have also reported mixed results concerning effectiveness. Some users say the rings did not work at all, while others say the heating effect is meager and not worth the expense--the rings cost much more than solar blankets, with 10 rings costing approximately $300. Sun Rings do come with a two year manufacturer's warranty against defects, but they cannot be returned based on disappointment with performance.

Bottom Line

Solar Sun Rings may be best suited for heating a swimming pool that is protected from excessive wind. The pool should also have adequate space nearby in which to store the rings when they not in use. If cost is a factor, a solar blanket is much less expensive and provides many of the same benefits.
