It's spring time and many homeowners are starting to think about opening up their pools for the season. Did you know that a solar pool cover can actually allow you to use your pool earlier in the year and use it well into the cold months? If you live in a sunny area, this could be a great way to get more out of your pool, start harnessing the sun's energy, and go green!
How Do They Work?
These pool covers have two features that allow to work efficiently. First, they absorb the sun's heat and rays with a network of air pockets. These pockets appear to be very similar to the bubble wrap you use for protecting valuable items when moving. The air and plastic bubbles absorb heat from the sun and then transfer it into the water through an efficient bottom layer.
The bottom layer also performs the second function of cover. This layer acts as sort of a one-way street, allowing heat from the outside, while trapping the heat that is in the water. This is done with a space-age, UV-resistant material. This way the heat that is already in your water does not escape.
Can They Save Me Money?
Yes, solar pool covers can save you money. They can do this in a couple ways. Most importantly they lower the use of electricity or gas to heat the water. By trapping the heat already in the water and adding heat to the water when the sun shines, the cover reduces the work that the existing heater has to do.
They also prevent water evaporation. This means you'll have to add water to the pool less often, saving money off your water bill and conserving our most precious natural resource.
What Time Of Year Are They Used?
Generally they are used just about anytime the sun shines. They are best in climates that experience abundant sunshine, but have cool temperatures in the spring and fall. In these climates, the cover can extend the swimming season by weeks and even months.
Are They Expensive?
In short, no, solar covers are not expensive. For a typical 12'x24' underground pool, the cover itself will cost around $300-$500. This is slightly more than a comparable plastic pool cover. But remember you'll be saving money on your power and water bill as well. Typically a solar cover will pay for itself in just a few seasons.
Are They Hard To Use?
These covers roll in and out in the same fashion as the old fashioned plastic covers. The solar cover is slightly thicker than the old version, so the reel that is used to roll them up may need to be slightly larger. Every other aspect of the cover is the same as a normal pool cover.
