Solar Pool Covers: How Fast Do They Work?

A solar pool cover is a great way to keep your swimming pool clean and clear. Solar covers can also help you save money on energy costs, as they insulate against heat loss. But how fast do they work?

We’ll take a look at the pros and cons of these helpful products, as well as how long it takes for them to heat up a pool. This blog post will explore what makes a good solar cover and what factors affect its performance.

For example, does the color matter? What about size or thickness? Let’s find out!

How Fast Does a Solar Cover Heat a Pool?

As the weather gets colder, you may be considering purchasing solar blankets to warm up your pool. But how do solar pool covers work? How fast do they heat up?

Many people wonder why their pools can’t reach an appropriate swimming temperature. There are several factors that can influence water temperature, with one of them being the presence (or lack thereof) of a solar pool cover.

Solar covers work by trapping the heat from the sun and returning it to your pool water. This means that pool covers can be used for heating, cleaning, and preserving your swimming environment. They’re also compact, easy to use, and fairly inexpensive.

However, their effectiveness does depend on a variety of factors. First of all, the cover must be an appropriate type for your pool. Additionally, you’ll want to make sure that it’s clean, clear, and large enough to cover the swimming area.

Thickness also affects the cover’s durability and longevity or how long do solar pool covers last. The color of your solar cover also plays a role in how well it works. A darker cover works better than a lighter cover.

Though lighter colors aren’t ideal for heat absorption, they still contribute to its efficiency in some way or another. Black covers absorb the most heat and are best used for heating outdoor pools.


Blue and silver covers tend to produce the least amount of heat and are usually used for water filtration. Transparent solar covers don’t trap as much heat but allow the most amount of light through to keep your pool clean.

When Is the Right Time To Use a Solar Pool Cover?

Before you go shopping for solar pool covers, you’ll want to determine the best time to use one. For example, if your pool is outside in cold weather, it might be more convenient to purchase a black or blue cover that provides better insulation than an opaque or silver one.

On the other hand, if you have an indoor pool and plan to use the solar cover in warmer weather, it might be more beneficial to go with a transparent, silver, or blue cover that allows light through and doesn’t trap heat inside. For easy removal and installation use a solar pool cover reel
