Solar covers are the most practical and economical way to save on your swimming pool heating costs. Solar covers take the heat the sun gives off every day and use it to heat your swimming pool with no energy costs. This means that you can extend your swimming pool season into the cooler days of autumn and you can open your pool earlier in the spring. Solar covers reduce evaporation at night and capture and retain the sun's heat during daytime. Almost 70% of heat loss is due to water evaporation and a solar cover will help in reducing water wastage and costs. Solar covers, in conjunction with an effective heater, is the best way for you to enjoy your pool investment for longer for years to come.
