How Long Does a Solar Cover Take to Heat a Pool?

The pool can be heated, which is one of the simplest ways to extend your swimming season. Learn how long it takes a solar cover to heat a pool by reading this.

Heating the pool is one of the easiest ways to prolong your pool season. A solar cover is an additional more cost-effective and environmentally friendly option to heat your swimming pool despite the fact that pool heaters come in all shapes and sizes. So we have to ask ourselves, “How much time does a solar cover keep a pool warm?”

Depending on the weather, a solar blanket can increase a pool’s entire water temperature by up to 10-15 degrees in a single day. In this blog, we’ll explore the time that a solar cover takes to heat a pool in detail.

How Long Does a Solar Pool Cover Heat Your Pool Water?

Several variables, such as the type of solar cover you have and the weather, affect how quickly a solar pool cover will heat your pool. As a result, it’s challenging to come up with just one solution. But typically, a solar pool cover will heat your pool by up to 10-15 degrees in just 12 hours.

It is important to note that solar pool covers work best alongside other heat sources as their main job is to maintain heat by preventing evaporation. On its own, it won’t be as effective, if at all.

Factors Determining How Long a Solar Cover Takes to Heat a Pool

To better understand how fast a solar cover works, I will detail factors determining how quickly these solar covers heat pools.

Type of Solar Pool Covers

Liquid solar covers, solar rings, and solar blankets are the three different types of solar pool covers. Although all three types are efficient, they are not all equally efficient.

  • Solar Blankets

Solar blankets are often called bubble solar covers due to their similarity in appearance to bubble wrap. The entire surface of the cover is covered in tiny thermal bubbles, which are their main component. The bubbles keep your water warm and humid while absorbing UV rays. Preventing evaporation is a simple and effective way to keep your water warm.

  • Solar Rings

Solar rings are a great alternative to solar blankets. You can use them for any type of pool, and they are lightweight and simple to use. With the addition of magnets that help connect them to each other so they stay in place, they function very similarly to solar blankets.

Due to their smaller size, solar rings are simpler to install; however, uncovered pool areas present an additional disadvantage. Due to this one flaw, solar rings are effective but may not be as effective as solar blankets.

  • Liquid Solar Covers

Liquid solar covers are a modern invention that is the easiest to deal with among the three solar cover choices. Simply pour the liquid into the pool to create an imperceptible, non-toxic barrier that keeps heat from escaping the pool. Liquid solar covers, in contrast to solar blankets and rings, work to maintain the pool’s temperature. This makes liquid solar covers 20-40% less effective than solid covers.

Weather Conditions

An important factor in determining how well a solar pool cover works is the weather. As previously stated, solar covers cannot heat your pool on their own and should not be your main source of pool heating. They need a different heating source, such as the sun or a pool heater, to function more efficiently.

It makes sense that the more sun your swimming pool is exposed to, the quicker it will heat up if you rely on the sun on to heat it up. For instance, a pool that is completely covered by a solar blanket and receives at least 6 hours of direct sunlight may reach temperatures of up to 10 degrees in a single day.

Alternately, even if you use a pool cover continuously for a week while the sky is cloudy, there’s a good chance that your pool may have only warmed up a few degrees.

The temperature at night should be considered as well. Since nighttime is when water evaporation occurs most frequently, the solar pool cover will be less effective at preventing heat loss as the night grows colder.

Surface Coverage

The size of the surface area covered by a solar blanket contributes to its superior performance over a solar ring or liquid solar cover. The solar cover will heat and retain heat more effectively the more surface area it covers. If your pool is not adequately covered, even if you use a pool heater and a solar cover, it will continue to lose heat to the cool air and heat-robbing winds.

Things to Consider Before You Buy Solar Covers

As far as solar covers go, they only work for smaller pools, specifically with a dark surface such as a dark pebble tech. Solar covers won’t help you much if you have a deep pool, especially if you decide not to use your pool heater to assist in the heating process.

How Long Does a Solar Cover Take to Heat a Pool?

When using a solar cover, keep in mind that they only function when your pool is actually covered by them, which can lead to a few problems. You probably won’t want to cover your pool again each night and then reopen it each day if you frequently use it during the warmer months.

They are also not beneficial in terms of cleaning your pool. Solar covers limit the amount of cleaning that can be done if you hire an outside pool company to keep your pool clean because they are likely not to remove the cover.

Can a Solar Cover Be a Replacement for a Solar Pool Heater?

Typically, solar covers are used in conjunction with a heating system, such as a solar pool heater. Solar pool heaters, however, can be quite expensive. Therefore, if you’re looking for a cost-effective and environmentally friendly way to effectively heat your pool, just having a solar cover might be a possibility.

The sole restriction is that solar-powered pool covers shouldn’t be used as heaters. Although they can certainly be used to heat the pool, their primary role is to prevent heat from escaping via evaporation.

So be aware that it won’t be as effective if you intend to use a solar cover in place of a solar heater. However, if you reside in a warmer state, you might not need to buy an expensive solar pool heater, so using a solar cover could be a great cost-saving measure.

Here is what you need to know about solar pool heaters:

Conclusion: Time to Decide

The experts estimate that a fully covered pool will warm up to between 10-15 degrees in about 12 hours. This depends on a number of factors, including the thickness of the cover, the pool’s interior temperature (if it’s an indoor pool instead of an outdoor one), how much direct sunlight the pool receives, and whether or not you’re using the solar cover in conjunction with a solar pool heater.

FAQs

Does Pool Heat Faster With Cover?

Your pool will maintain its water temperature at a higher level with a cover than without one. You can now enter the pool earlier in the day, which saves money on heating costs as well. Whether you use a heat pump, solar, or gas system, a pool cover will increase heat retention by up to 75%!

Can You Leave Solar Cover on Pool During Day?

No. Never, not even for a brief time, should you leave a solar cover rolled up in the sun. A bubble cover is designed to let sunlight pass through the bubbles.

Do Solar Covers Really Heat the Pool?

By harnessing the healing powers of the sun, solar pool covers offer the added benefit of raising pool water temperatures by an average of 10 to 15 degrees Fahrenheit. All of this translates to solar pool covers ultimately saving pool owners time and money.
