Best Solar Pool Cover

What is the Top Solar Heating Cover for Swimming Pools?

Regardless of whether your swimming pool is found outdoors or indoors, it is bound to lose some energy as a result of evaporation. That also means that the water levels will go down significantly.

Strictly speaking, you will need some ‘make-up’ amount of water for replacement.

But did you know that there are solutions you could employ to prevent such unnecessary problems? Using a pool cover will help you by far. In simple terms, a pool cover is just a type of plastic.

Buy we are not saying that you can use any type of plastic to serve the same purpose. While it can capture some vapor, it might not turn out to be exactly what you want. 

You have to consider their ability to survive the harsh UV rays, how easy they are to handle, as well as their durability.

That said, there are different types of pool covers that you can get in the market. They include solar or bubble covers, vinyl covers, among others. This article focuses on solar pool covers.

Spotting the best solar pool cover may be a nerve-wracking task given the millions of options out there. Here are our top picks.

1. In The Swim

For a quality product, this is worth giving a shot. In the swim is a 12 millimeters pool cover. It’s thick enough to ensure that most of the heat remains locked, and that your pool does not lose too much energy or water.

The process is made much easier thanks to the resin used to design the product as it is adapted to survive the UV rays. Also, some trapped bubbles of air help in retaining the vapor.

Perhaps, you are wondering how that works. The solar cover traps the heat from the sun and then conveys the same to your swimming pool water. Consequently, it prevents the heat from escaping in the form of vapor, minimizing on energy and water loss.

Moving on, it is important to mention that the pool cover is adjustable. In this context, it simply means that it can be cut to suit the size and shape of your swimming pool.

Besides, it comes with a 7 years long warranty duration.


  • Comes with a product warranty
  • It is 12 millimeters thick
  • Can work in any prevailing weather condition


  • It is a bit pricey
  • Does not have the best appearance

2. Sun2Solar 20*40’

In the second place, we have the Sun2Solar pool cover. Just like our first pick, this one has numerous bubbles of air which help in trapping and conserving heat whether from the sun or otherwise.

This ensures that when you are not using your swimming pool, water levels remain balanced and you do not have to do the re-filling or wasting a lot of chemicals to balance the levels.

Now, there are people who prefer to buy a pool cover that will help with heat retention while not sacrificing the looks. If you fall within that category, this will be an excellent purchase.

It comes in an eye-catching blue color that will serve you right.

Also, it is not uncommon to find swimming pools that are of different sizes or maybe shapes. What that means is that there can be no universal one-type-fits-all kind of pool cover.

To take care of those unforeseen technicalities, Sun2Solar has some allowance in the size such that you can cut it to get the perfect model for your swimming pool.

Thanks to the resin and air bubbles, the rate of water loss through evaporation is minimized by a great percentage.

Besides, splash will also help to stop dirt and small stones from getting into your swimming pool when you are not using it. This is thanks to its design which has no drainage openings. 

As a result, it also reduces the amount of time you would otherwise need to do regular cleaning. It also cuts on the amount of chemicals that you would use to re-balance the water and related things.

The blue one plays a crucial role in capturing heat from the sun and transferring it into your swimming pool’s water. The cover in its entirety then prevents the heat loss and also attempts to retain the water levels.

On the flip side, the silver color plays a different role when it comes to heat retention and generation. It functions by reflecting off the heat that has been absorbed by the surfaces. This is directed into the pool cover.

In turn, it helps in keeping the water warm in low-temperature conditions.

Dimensions are of essence whenever you are trying to get a pool cover. This one measures 18 feet by 40 feet, so make sure it can fit your pool before purchasing it.

Factors to watch out for before buying a pool cover

Now that we have already listed some of the best pool covers that are available in the market, we want to take you through some of the factors that come into play when you are purchasing one.

Obviously, it might still be challenging to settle for one product from the 10 above, the main reason being you don’t know which ones best suits your pool. That is to say that your knowledge is incomplete until you have gone through this section.

So what are those factors? You will not just walk into a shop and ask for Thermo-Tex or Sun2Solar. You have to consider the shape of your swimming pool. Is it rectangular or circular?

Also, look at the durability of the cover, its weight, color, thickness, and warranty.


Needless to say, swimming pools are made in different shapes. We have the rectangular-shaped ones, circular ones, and others. Thus, you ought to go for a pool cover that is made in the same shape as your pool.

That is the universal rule of thumb.


Another aspect that goes in tandem with the shape of the pool is its size. You want to ensure that the pool cover perfectly covers every inch of the swimming pool for maximum performance.

Failure might result in leakage of heat or vapor into the atmosphere, hence inefficiency. The size of the pool cover is the most important aspect to watch out for. 

The first step should be measuring your pool’s dimension. You can repeat the process just to be sure. In case the cover is too big, you can always trim it down to correspond to those dimensions.

Just ensure that it is not small. 


After the size and shape, the other aspect that you want to check is the product warranty. All products are bound to experience some wear and tear during the course of their use. Or rather, they may be delivered to you in a bad condition.

What do you do with such products? In the absence of a warranty, you may be condemned into setting it apart and going for a new pool cover or even repair it. That means fishing out a couple more dollars.

A warranty will take care of such problems provided they arise when the duration has not expired.


Besides the appearance of your swimming pool, the color of your pool cover plays an important role when it comes to heat absorption and maintenance. There are 3 main colors that you are likely to come across.

We have the clear covers that are good at absorbing the heat energy from the sun. We then have the dark-blue colored ones that are excellent in retaining the already trapped heat transferred to the water.

Finally, we have those that bear a light blue shade. These ones fall in the middle. They strike a balance between the rate of heat absorption and retaining. 

However, you might also come across combinations such as blue and silver. The silver part helps in reflecting heat that has been absorbed by the pool’s surface back into the pool cover and into the water.

Therefore, you have to weigh your options and decide which color you want for your pool.


The thicker the pool cover is, the better it will be in retaining heat and preventing escape of vapor into the atmosphere. 

You should however be warned of the downside as thicker covers tend to be more bulky. Thus, handling them may be a tedious task. You don’t want to buy a cover that you will end up keeping away because they are cumbersome to use.


Saving on the costs of keeping your pool’s water warm is an idea that best resonates with any swimming pool owner. The simple way of achieving that is by using a solar pool cover.

However, the cover is not restricted to such a function. Besides capturing the heat energy from the sun and conveying the same to the water, it also goes out of the way to maintain the water levels.

Simply, it prevents the water from evaporating and escaping into the atmosphere. It will also prevent dirt from getting into your pool when you are not using it. 

Looking for the best solar pool cover? We recommend the ‘In The Swim’ product. The pool cover is 12 millimeters in thickness. This is a good pick to see to it that the heat from the sun remains locked in, and that the water does not lose its energy.

The model is also made from UV-protected plastic material that improves its durability. This also ensures that there are no chemicals leaking into your pool’s water.

Since each pool has its unique shape and size, this product can be trimmed to your pool’s peculiar dimensions.

In the Swim is a pool supply company that sells its items primarily online, through its own website and places such as In addition to selling pool chemicals, pool lines, and pool equipment, In the Swim produces a line of solar pool covers that are generally well-received by its customers.

Each solar pool cover is designed to raise the water temperature of the pool by both capturing natural light and by insulating the pool, preventing existing heat from escaping. Unfortunately, In the Swim’s website doesn’t provide specific temperature-raising facts for each pool blanket. Despite the significant difference in thickness between a 5-mil cover and a 16-mil cover, both products’ pages claim a 10 to 15 degree temperature increase.

Installation and Sizing

One benefit of the In the Swim solar pool cover products is the wide range of sizes. Regardless of the size or shape of your pool, you should be able to find a pool cover that matches. Reels must be purchased separately.


The only complaint from owners of In the Swim solar pool covers is that the solar bubbles tend to shed after a few years of use. This is a fairly normal complaint about solar pool covers in general. Although they are built to absorb sunlight, the sun also wears them out over time. Some customers report that the thinner solar pool covers are more likely to tear and wear out more rapidly than the thicker covers.


As previously mentioned, the solar pool covers by In the Swim differ mostly only in size and thickness. Thicknesses available include: 5-mil, 8-mil, 12-mil, and 16-mil. The two thinner blankets come with a three-year warranty; the two thicker blankets come with a 7-year warranty.

The Bottom Line

The negative reviews generally center around two complaints: the longevity of the pool cover and the ease of use.
