Aquatherm Sun-Swim Plus 4ft x 10ft Solar Pool Panel 1.5" Header

Simply Wonderful

Owning a swimming pool means poolside parties... early morning workouts... refreshing dips... family fun and romantic late night swims. Owning a Sun-Swim pool heater means more enjoyment more often. Join the hundreds of thousands of pool owners that have extended their swimming seasons with a solar pool heating system.

Wonderfully Simple

Using your existing pool pump, water is circulated through the many small passages of the solar collector, where it is warmed by the sun. This warm water then flows directly back to your pool through the regular pool plumbing. The Sun-Swim pool heater is designed to work with your existing pump and equipment.

Built to Last

Sun-Swim solar collectors have been designed from thirty years of experience in manufacturing of solar heating equipment. They have undergone extensive testing resulting in performance certification by accredited independent laboratories and approval agencies. Performance rated at 1,000 BTU's per square foot by the Florida Solar Energy Center
