The SunGrabber solar heating system will quickly heat your swimming pool with free, reliable heat from the sun. A properly sized solar system will provide virtually all of the heat for your pool - free! Sungrabber captures the free renewable energy from the sun to heat your pool, reducing or even eliminating your water heating bill and reducing the amount of electricity you use. The system circulates pool water through solar panels and uses solar energy to warm the water as it returns to the pool. Our panels feature 1-1/2" headers, which allow for excellent circulation through the solar panels, thereby maximizing the solar efficiency. Additional panels can be added to the system to achieve optimal heating capacity. For total solar heating, the solar panel square footage should be at least equal to 50% of the pool's surface area. Our SunGrabber Solar System can supply 100% of your pool's heating needs. Comes with easy to follow instructions for a simple do-it-yourself project.
