Cover picture for the article

Solar pool covers absorb the sun’s heat and transfer it to the water to warm a pool to a comfortable temperature for swimming. Made of vinyl, polyethylene, or polypropylene, the best solar pool covers also insulate the pool when the sun goes down. A solar pool cover can lower the cost of heating a pool by as much as 70 percent because the pool heater won’t have to run as much. Solar pool covers, like hot tub covers, also prevent evaporation, lowering your water bill, too.
