For those who like their pool water a bit warmer, a solar cover might be the way to go. However, there are several factors to consider before buying a solar cover for your swimming pool.
A popular misconception is that solar covers heat your pool quickly. Actually, the opposite is true. Don't be fooled by surface temperatures. A solar cover will only heat the first 6 inches of surface water on its own. If you want your entire pool to be heated, it is recommended you have another heat source. Solar pool covers work well when used with a solar panel or other heat source.
Solar covers are an inexpensive way to retain heat loss through the evening hours. They also work best if your swimming pool has maximum exposure to the sun.
In addition to heat retention, solar covers also help maintain your pool's chemicals, but be aware that they can also harm the cover. Chlorine can be your solar cover's enemy if not monitored properly.
When considering a solar cover purchase, keep in mind who will do the installation and removal. Depending on the size of your pool, the cover may require more than one person to remove it. You can also purchase an expensive reel system that will wind up your cover, thus removing it from your pool.
The typical life span of a solar cover is 5 years, provided that it is kept in good condition and not dragged on the ground or across your patio. It is also recommended that you do not store your solar cover on the ground to avoid any pest infestation.
Solar covers are an excellent choice of heat retention for your swimming pool if you are looking to cool off on a hot summer day without the shock of frigid water. If you are looking for long term heat retention, you might want to consider a gas heater.
