How Does a Solar Pool Cover Work?

By now, I’m sure you know that solar pool covers are must-haves. They can be light and they can also be heavy. They keep your water temperature warm and can save energy, water, and chemicals.

Question: How does a solar pool cover work?

1. The solarpool cover will first collect heat. This heat comes directly from the sun.
2. When the sun is hot (as it always is) and the air is warm, the pool can also get warmer.
3. At night, when the outside environment is cooler, all the heat that your pool collected will escape from the pool water. That is if you don’t have a solar pool cover. If you have one, it will trap the heat and prevent it from escaping your pool; keeping your pool water at a warm temperature. In most cases, solar pool covers will warm the pool water temperature about 4-8 degrees Fahrenheit.

A question again: So, how should I use my solar cover?

Simple. First, make sure your pool’s system isn’t running. If it’s running and you’ve place the cover, it will bind it up and prevent it from spreading out and doing its task. Second, you have to place the cover on the pool water with the bubble side down. Because the cover has air bubbles on it, it will float. Next, make sure you don’t let your cover hang over the sides of your pool or up on the deck. If this happens, it means your cover is too big. So cut off the excess to it can fit inside the pool but still be able to cover all of the water surfaces. Some solar pool covers can catch debris that fell onto it, so don’t forget to clean it up before keeping it and using it again. However, you shouldn’t be very much hopeful about the amount and size of debris it can hold. After all, it’s meant to trap heat and not debris.

In case you need to cut off the excess part of the solar pool cover, make sure you do it when no one is in the pool, which is usually at night or early in the morning.

Another question: How does a liquid pool cover work?

When you pour a liquid pool cover into your swimming pool, it rises to the surface because it’s lighter than water. When it reaches the surface, it will start scattering itself across the surface. The molecules, which are so tiny, that make up the liquid pool cover prefer to sit side-by-side instead of piled up on top of each other. And because of this, they will keep moving sideways to sit next to their colleague until there is nowhere else to move to—when they find the outer edges of your swimming pool. They will then be close enough to cover the entire surface of your pool without being noticed by your naked eye. Simply put, they’re invisible pool covers.
