The 4 Best Solar Pool Covers To Buy in 2020

An overview of Solar Pool Covers

Swimming pools are a great addition to a home that can provide many hours of fun, relaxation, and entertainment during the warmer seasons. Of course, cold water can be fun to play around in, but how would you feel about being able to use your swimming pool in the winter season too?

It’s not just a novel idea, however, since you actually can keep your pool water warm if you invest a bit of money into a solar pool cover. With a solar pool cover, it is not necessary to pay for electricity or gas consumption since all you have to do is adjust the cover in a pool full of water and they act by warming the water for an extended amount of time. Now that you have been given a primer, we will recommend the best solar pool covers available on the market.

What is a Pool Cover?

Pool covers not only keep debris out of your pool but they warm up your pool too, serving double duty and keeping your cleaning costs down at the same time. Typically, pool covers are made from polyethylene or vinyl, with the material usually transparent or opaque. The following solar pool covers have been vetted and are considered some of the best that the market has to offer.

Swimming pools can lose energy in many ways, but the biggest energy loss by far is evaporation. In order for water to evaporate, a considerable amount of water must evaporate, with the evaporation rate based on the pool’s temperature, humidity, air temperature, and the wind speed that is at the surface of the pool. For an optimal evaporation rate, the pool temperature and wind speed should be higher and the humidity lower. In areas that are windy, it is advised to add trees, shrubs, or a fence as a windbreak that can reduce evaporation. The windbreak should ideally be higher and close enough to the pool so that no turbulence is created over the pool as this leads to increased evaporation. Another important note is not to shade the pool as this takes heating properties away.

Even indoor pools, which don’t have to deal with the elements, can still suffer from energy loss because of evaporation. Indoor pools require room ventilation that controls indoor humidity that is caused by large evaporation amounts. Energy costs are affected by the ventilated air that must be conditioned. For users that want to invest in a solar pool cover, these products are able to minimize evaporation in both outdoor and indoor pools. The most effective way to reduce pool heating costs is to keep it covered when not in use. When covered and secured, users can expect to save between 50% to 70%. For consumers that have an indoor pool, a pool cover can reduce evaporation, but it is necessary to ventilate the indoor air and replace it with outdoor air that is unconditioned. Another way to save energy with an indoor pool is to shut off any exhaust fans when the solar pool cover is used.
