Pool HeatingThere are over 10 million swimming pools and spas in the United States, both residential and commercial, with more built every day. Most pools require heating in off-seasons to maintain a comfortable temperature between 70-80 degrees. The U. S. Department of Energy highlights solar energy as an effective choice to heat your pool while significantly reducing heating costs.
Solar Swimming Pool
Solar swimming pool heating is the most cost effective application of solar energy and increases the number of days you enjoy your pool. Even when used without a cover a solar pool heater can economically double the number of days you swim. Using the sun to heat your pool will reduce your bills and increase your enjoyment.
Solar pool heaters are integrated into the normal pool pump/filter system and work
by intercepting water after it comes out of the regular pool filter, directing it through the solar collectors, and then returning it to the swimming pool.
The water temperature is raised significantly as it passes through the collector array. A sensor that determines how much additional heat is needed to achieve the desired warmth controls the final water temperature.
