A SunHeater solar pool heating system can raise the temperature of your pool water 7-10° F. 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. As long as there is a minimum surface space of 21', the system can be installed on the roof of your house, shed, cabana, mounted to a rack, or simply placed on the ground. With this system, you'll save money on fuel and electricity bills, extend your swimming season by weeks, and get more enjoyment from your pool than ever before.

Systems are available to suit all sizes of above ground and in- ground pools. This system contains two 2' x 20' SunHeater collectors. If you wish to mount the heating panels, you'll need the SmartPool SunHeater Roof/Rack Mounting Kit (SK43).
