Features

NSF TESTED AND CERTIFIED PRODUCT QUALITY: SwimEasy solar pool heater panels are made in the USA, undergo rigorous manufacturing techniques to increase life expectancy, and hold up against the strict testing standards required for NSF certification. A process of melt-blending plastics with special additives is key. This process is more expensive, however eliminates the quality issues of cheaper manufacturing methods which result in plastics that generally last only a couple years.

FIELD PROVEN RELIABILITY: SwimEasy’s high-grade materials & specialized manufacturing techniques make the panel capable of withstanding the harsh conditions of a rooftop, in all types of weather, for 15-20 years! Each panel is subject to 40+ quality control inspections throughout the manufacturing process to ensure the final product. These same materials are used by some of the country’s most renown residential & commercial installers due to decades of proven performance & reliability.

HIGH PERFORMANCE “ZIPPERED” PANEL DESIGN: SwimEasy’s solar panel design maximizes heat absorption while minimizing the amount of heat lost by restricting wind loads from passing through each riser tube. Each collector contains 7 "zipper-seams" down the length of the panel. These allow the panel to be "unzipped" at multiple locations to fit around small roof obstructions, while staying “zipped” when unneeded. This functionality allows for installation flexibility while maximizing heat retention.

LEAK-FREE CONNECTION METHOD: SwimEasy utilizes heavy duty CPVC pipe connectors for making connections with PVC pipe. Plastic threaded fittings do not provide a secure connection and tend to leak quite frequently. SwimEasy contains no threaded fittings, instead making connections through glued slip attachments to PVC pipe, as well as grooved & barbed clamp attachments to durable EDPM rubber couplings (designed specifically for solar pool heating), creating a completely secure, leak-free seal.

A SYSTEM IS ONLY AS GOOD AS ITS PARTS: The SwimEasy DIY kit comes packaged with premium installation components that are vital for unlocking true performance and longevity. It's pointless to provide a quality system if not accompanied with quality parts. Using higher grade hardware really make a difference, both in performance as well as life expectancy. For a breakdown of exactly what parts are included, please scroll down to the section titled “What’s Included”.

Features

SPECIALIZED STRAPLESS MOUNTING: Superior rail mounting system allows for strapless flush mounting to any roof type. SwimJoy solar panels are secured at both the top and bottom manifold, producing an extremely secure attachment while allowing for thermal expansion and contraction. This design enhances mounting security in high wind climates and enables SwimJoy to withstand strong storm winds. This design also adds flexibility to the number of mounting locations available on each manifold.

ONE OF THE MOST ROOF-FRIENDLY SYSTEMS AVAILABLE: SwimJoy’s mounting sleds elevate each riser tube above the roof’s surface and allow the roof to breathe, prevent moisture buildup, and virtually eliminate wind loads. When combined with SwimJoy’s separated tube design and rail mounting system (which requires only one anchor per pad), the result is fewer penetrations and a more aesthetic installation. These innovations set SwimJoy apart & make it one of the most roof friendly systems available!

LEADING ATTACHMENT METHOD: SwimJoy features the patented Panel Clamp Assembly connection system with a proven record of being the best industry method for connecting panels together and to PVC plumbing. This clamping style eliminates traditional rubber hoses and hose clamps which deteriorate over time requiring maintenance and replacement. This low-profile connection also drastically improves aesthetics, allowing panels to be mounted closer together for a cleaner, more attractive appearance.

TOP-OF-THE-LINE MANUFACTURING: SwimJoy’s unique square header maximizes flow and increases efficiency. Headers and risers are formed together through a patented manufacturing process creating a single solid piece, eliminating seams and welds that can crack with age and stress. This produces the strongest possible connection and ensures a low maintenance system.

PREMIER PURCHASE PROTECTION: SwimJoy solar pool heater panels are protected by an industry leading 12-year limited warranty that includes a bonus lifetime limited warranty and freeze protection; the longest - most comprehensive warranty coverage in the industry.
