The Solar Safe Pool Cover is a passive solar heater, helping to convert sunlight into heat for your pool water. This can allow you to swim earlier in the spring and later in the fall than you would in an uncovered pool. Independent lab tests have shown that the Solar Safe Pool Cover adds more heat to your pool than the solar/blue bubble covers you often see in pool stores.
The PowerLock Pool Cover absorbs heat from the sun, and transfers it to the top few inches of water in your pool. To maximize the heat gain, circulate the pool water with your pool pump and filter during the time the cover is exposed to maximum sunlight. Generally, this means filtering your pool for 2 to 4 hours between about 11 AM and 3 PM, depending on when your pool receives the most sunlight.
If you don’t wish to increase the heat in your pool, run your pool pump only when there is no sunlight on the PowerLock Pool Cover.
If you have a supplemental gas pool heater or heat pump, the Solar Safe Pool Cover can help to reduce your fuel costs, primarily by reducing heat loss at night and by reducing evaporation from the water surface.
