  • Quick & Easy Installation: Installation is effortless with included hose clamps, adapters and connectors. Simply connect to your pool heater system with a pump that minimum power of 0.75HP and a pressure not exceeding 21 PSI. Regular cleaning ensures peak performance. (Pumps not included).
  • Adaptable and Fully Equipped: Includes two 2.5'W x 10'L panels that can be connected as required. We also offer two other lengths to suit any size of above-ground or in-ground pool to choose from. The solar powered heater comes with rubber end caps, hose clamps, adapters, and elbow connectors for a quick setup.
  • Guided Size Selection: For medium sized pools such as a 12'/18' diameter or a 12' x 24' area, select either a 16.5FT or 20FT heater. Larger pools measuring 21'/24' or 16' x 30' typically require two 16.5FT or 20FT heaters, while smaller pools are well served by the 10FT model. Adjust quantities according to specific size requirements to ensure efficient heating.

  • FLEXIBLE ZIP-JOINT SYSTEM - Flexible zip-joints located every 6 inches across the absorber surface eliminate stresses caused by natural temperature variances between panel sections by allowing the panels to move along the joint freely - increasing durability.
  • INCREASED FLOW – SwimEasy’s header is molded directly around the absorber tubes, eliminating flow barriers, so water freely exits the header into each individual tube. Simply put – the more water that can flow through your heating system, the more heat that will be transferred to your pool.
