The heat is then transferred from the pool to the cover which is then stored as warmth. These can also be left on the pool at night to keep the cover warmer than air temperature.

Frequently Asked Questions (FAQ)

What is the best thickness for solar pool cover?

The majority of solar pool covers are made of 12- or 15-gauge woven polyethylene plastic. These are fine for most circumstances, but you can opt for the more expensive and durable 16-gauge polyethylene plastic or even a vinyl-coated material if you’re concerned about the longevity of your solar pool cover.

Where solar pool covers are concerned, thickness is an issue, especially if you want to use your pool continuously into the fall. With that in mind, the minimum thickness of any solar pool cover is one that provides a 90-day overlap.

Which solar cover is the best for pool?

Your pool is going to lose a lot of water in a year. Even if you close it at the end of every day, the heat will evaporate up to 2 inches a week.

This can lead to a couple of issues. Firstly, you won’t have enough water to swim in some summer days. Second, your heating costs will be unnecessarily increased since you are running a pool that is, in effect, empty.

So, it’s worth the investment to get solar swimming pool covers to avoid this problem. There are a number of considerations to make when picking one, though.

If you have a small pool and don’t lose a lot of water, a cheap swimming pool cover might be good enough.

Are solar pool covers any good?

Solar pool covers are much less complicated than they used to be, though installation can still be a bit tricky. For a solar pool cover to be effective, it must be placed directly on the water and cannot be placed on top of any other objects. If you do place it on top of a raft, then the cover will likely not be able to suck up the water on its own.

Another important aspect of solar covers is their thickness. Ideally, you would like to find a cover that is as thick as possible. This is because solar heat is absorbed through light. The thicker the cover, the more light that can be absorbed. Inversely, the more heat absorbed, the more evaporation will occur, reducing the need to pump water. Avoid ultra-thin covers as they often do not provide the benefits that thicker covers bring. If you can find a cover that includes built-in pump, this is even better.

Is a blue or clear solar pool cover better?

Many people wonder if a blue-colored solar pool cover is also the most effective solar cover for their pool. The answer is yes, but the explanation may be a little more involved.

For starters, blue solar covers do hold more heat than clear covers do. A little less obvious as a benefit of a blue cover is that people seem to have a little more tolerance for high water temperatures versus colder water temperatures. Of course, we aren’t really talking about hot tub temperatures; weʼre simply describing the range that most people are able to stand before it becomes uncomfortable.

This is why we optimize our swimming pool covers around 84ºF/29ºC as this is comfortable for most people. Any higher than that and you’ll find most people are ready to get out.

Conclusion

A good pool cover is one that will protect your pool. It has to be effective in preventing debris and water evaporation, which are two of the main issues affecting an unprotected pool. There are many solar pool covers that are available in the market. We have done the research and listed the 6 best solar floating covers.
