Energy-efficient Solar Heater: Without connecting extra energy sources, the solar dome heater significantly raises the water temperature. It collects heat from the sun, so that cold pool water flows into the solar heater. By using pump (Not Included), the warm water is returned to the pool . It is recommended that use a 1-2HP power pump with up to 16 GPM flow rate.

Dome Cover and Black Coil: The transparent dome cover with convex surface can better gather heat and keep inside clean from debris. With built-in black coil, the dome heater helps captures and retains the heat more efficiently, to raise your pool’s temperature by 5.4-7.2.
