Solar pool heating systems enhance the natural effect of the sun heating the water in your pool with three basic components: a panel, a pump and a filter. A pump, usually your existing pool pump, pushes water through a filter to strain leaves and debris. Water is then pumped into a Heliocol solar panel mounted on your roof, porch, fence, or any other location with good sun exposure (optimally south facing in North America). The water is substantially heated as it moves through the panel and it flows back into your pool, warming the water. Unlike solar water heaters for indoor use, solar pool heaters do not require a storage tank. Your pool provides all the storage required.
