The 5’ Solar Sun Rings Blue is a passive solar heating solution that helps warm pools using natural sunlight while conserving water and reducing chemical use. Made with durable, UV-resistant vinyl, each 5’ ring features a dual-layer design that captures and transfers solar energy efficiently. Encapsulated magnets allow multiple rings to raft together for full-surface coverage but easily separate for safety. With built-in drainage grommets to prevent sinking, this system is ideal for pools of any size.
