Using the pump that circulates pool water through the filter, the water is automatically diverted by an Electronic Temperature Control (1) and a motorized valve (2) so that it flows through the many small passages of the solar collector (3). While passing through the collector it is warmed by the sun. This warm water then flows directly back to the pool. When the pool has reached your desired comfort level, the water then bypasses the solar collector and returns directly to the pool. contact Gen-Conreturn to Home
