Solar Covers and Sun Heaters for your above ground pool Solar blankets heat the swimming pool by day and insulate it at night. If left on when the swimming pool is not in use during the day, the blanket allows the sun's rays to pass through the bubbles to heat the swimming pool water during the day. At night, the bubbles act as an insulator minimizing heat loss. Extend your swimming season, you can enjoy water 10-15 degrees warmer than the weather warrants. A solar cover from My Pool Supplies can even reduce your pool heater bills by 70%.
