By capturing the heat already in the water and adding heat to the water when exposed to sunlight, the cover reduces the work of the existing heater.

They also prevent the evaporation of water. This means you have to refill your pool less often, which saves on your water bill and conserves our most valuable natural resource.

What time of year are they used?

In general, they are almost always used when the sun is shining. They do best in climates with lots of sun lights but cool temperatures in spring and fall. In this climate, tablecloths can extend the shower season for weeks or even months.

Are they expensive?

In short, no, sun protection is inexpensive. For a typical 12'x24' underground pool, the cover alone costs around $300-500. It's little more than a comparable plastic pool cover. Remember, however, that you will also save money on your electricity and water bills. Sun protection usually pays off after a few seasons.

Are they difficult to use?

These caps roll in and out like old-fashioned plastic caps. The sun visor is a little thicker than the old version, so the reel used to spin it may need to be a little larger. Every other aspect of coverage is the same as normal pool coverage.
