In simple terms, how does a solar pool heater work?
Using the pump that circulates pool water through the filter, the water is automatically diverted so that it flows through the many small passages of the solar collector. While passing through the collector, it is warmed by the sun. This warm water then flows directly back into the pool. When the pool has reached your desired comfort level, the water then bypasses the solar collector and returns directly to the pool.
Solar pool heaters can be explained very simply. Using your pool’s pump, water is directed to the panel’s solar collectors. The panels are usually mounted so that they will get the maximum direct sunlight on any given day. The water is heated as it moves through the collectors. The heated water is then returned to your pool through the return lines. They are effecient and long lasting. They will heat your pool water by up to 15 degrees.
