The greatest loss of heat in a pool occurs at its surface because of evaporation. In general, pool covers reduce this evaporation and help keep the water warm and clean. Unlike average pool covers, solar pool covers go a step further. They are specifically designed to absorb the sun’s heat and transfer it to the pool water. The surface of a solar pool cover consists of a film of tiny air pockets or bubbles. It is similar in appearance to bubble wrap. In this case, each bubble collects and retains heat, which returns to the water rather than being dissipated into the atmosphere.
Solar pool covers work best in sunny areas where high amounts of sunlight can be absorbed. While they help keep the pool warm during hot summer days, they can also extend the swimming season beyond summer. They also help reduce heat loss at night by insulating the pool and keeping cool temperatures and wind out.
Solar pool covers are often made from synthetic polyethylene material and have absorbent dark blue or gray colors. They come in all shapes and sizes and float above the top of the water without tie downs or anchors. Solar pool covers are equally effective for in ground and above ground pools. They can be expected to last 3 to 5 years.
Solar pool covers can increase pool temperatures by 10 to 15 degrees, reducing heating costs by up to 75%. This is much more than an average pool cover, which can increases the temperature of the pool by 5 to 10 degrees, and only when used for up to 20 hours a day.
An important thing to keep in mind is that solar pool covers aren’t specifically designed for cleanliness. They are also not meant to prevent children or small animals from entering the pool. Solar pool covers should be removed completely before swimming.
