http://www.mysolarpoolheaters.com/page/473540499 A SunHeater™ solar pool heating system will raise the temperature of your pool water by up to 10°F or more. It is lightweight, durable and easy to install. Water simply flows through the SunHeater’s many tubes via your existing pool pump where it is heated by the sun and returned to your pool. The system can be installed on the roof of your house, shed or cabana, mounted to a rack, or simply placed on the ground.
