Do Fountains Keep Pools Cool? (What Should You Know)


Yes, fountains do keep pools cool. Having a pool in the backyard of your house is definitely a great idea. But what’s the use of a pool if you cannot cherish a refreshing pool swimming session on a burning summer evening? 

Well, here comes the need for a fountain.

Fountains apparently appear as elements that can potentially add aesthetic values to your housing property. But there is more to this beautiful artefact. In this article, we’ll run you through everything that you might need to know about how fountains keep pools cool. Watch out.

Can Fountains Cool Down the Swimming Pool?

During the summer season, the swimming pool’s water temperature usually tends to rise up. Even if you have installed an insulator in your pool, it doesn’t make a significant difference. Ultimately, your swimming pool turns warm, and your swimming experience turns out to be an unpleasant one.

Installing a fountain in your swimming pool is one of the effective methods to reduce water temperature levels. Fountains play a vital role in keeping the pool water circulated at regular intervals. Therefore, the temperature naturally cools down, and you beat the scorching heat with a dive.

However, you have to choose a fountain according to the size of your swimming pool. This will ensure that the water temperature stays somewhat manageably cool. Otherwise, if you insert a significantly small fountain on a large pool, it won’t effectively cool down the water temperature.

In addition, you need to consider the location of your fountain and get an appropriate water pump for effective results. The location of the fountain will help you maximize your desired results. If you manage to do all these things successfully, you can enjoy your pool time even during summer.  

How Does A Fountain Help to Cool Down the Pool Water Temperature?

Now that we have already established that fountains help cool down the pool water temperatures, let us get you through how it works to make the water pleasant during the summer seasons.

After the installation, your fountain starts its operation by circulating the pool water. For starters, it sprays water on the surface of your swimming pool. Thus, the process creates water splashes when it throws the water in mid-air. The method also adds oxygen to existing water molecules, and the water temperature cools down.

One of the most prominent methods of cooling down the water is aeration. A fountain usually performs a surface-level aeration process, where it pumps the water into the air. In this process, it creates small water droplets, which collect oxygen in mid-air from the atmosphere. Then, it reaches the surface of your swimming pool.

The oxygen which the water droplets collect in the air helps to replace the existing warm water molecules. So, when it reaches the surface water, they add more oxygen to your swimming pool. Thus, the temperature of your swimming pool cools down significantly. As this spraying process continues, you can expect the swimming pool to cool down in about two hours.

What Are the Benefits of Installing A Fountain in Your Swimming Pool?

Apart from cooling down the water temperature in your swimming pool, fountains also have other benefits. So, the following points showcase all the major advantages of installing a fountain in your pool.

  • Helps to Cancel Out the Background Noises

When the fountain water touches your pool’s surface, it creates a splashing sound that helps you to cancel out other noises. For example, you can easily avoid annoying honking sounds, noisy neighbors, and irritating noises. The sound of the fountain is also therapeutic. Thus, you can enjoy and relax your swimming pool time being completely secluded from the world.

  • Cools Down the Water Temperature of Your Swimming Pool

We all know how the summer season can turn the swimming pool into an unpleasant system. But fountains help to keep the pool temperature levels under control by circulating the water. The circulation adds more oxygen to the water, which helps it to cool down. So, with a right-sized fountain, you can have a pleasant experience inside your pool, even during summertime.

  • Promotes Water Circulation Inside Your Pool

Apart from cooling down the temperature, pool circulation has numerous benefits. For instance, it helps to distribute useful chemicals equally in the entire pool. It also helps to filter out the water. Thus, it prevents the birth of harmful bacteria and algae inside your pool. The fountains in the swimming pool help the water pumps to function effectively.  

  • Adds an Aesthetic Value to Your Pool

Fountains can elevate your pool view with innovative swimming pool designs and decorations. Generally, you can find them in all shapes and sizes. So, finding the perfect one for your pool won’t be a hustle. However, before choosing one, make sure to keep the home design and surrounding areas into account. Ideally, a fountain must effortlessly blend with the surrounding environment.

What Is the Ideal Time to Activate the Fountain in Your Swimming Pool?

The ideal season to run the fountain in your swimming pool is during summer. However, to cool down the temperature effectively, we recommend you activate the fountain at night. During this time, the water temperature reaches its peak, but the surrounding air cools down significantly.

As the fountain splashes the water droplets, the oxygen molecules present in the environment will react with the droplets. And this process will cool down the water temperature. Moreover, the surrounding air is much colder during the night. Therefore, it will ensure that your swimming pool’s temperature is cooling down.

But if you decide to run the fountain during the daytime, it won’t make much of a difference. So, the nighttime is perfect for obtaining your desired result. In fact, since the air temperature remains low, the water temperature can cool down more than you expected.

The experts also suggest not to activate the fountain when the surrounding air is too hot. If you decide to run the fountain during the daytime when heat levels are at their peak, it will make the swimming pool even warmer instead of cooling it down.

It is because when the fountain splashes the water in the atmosphere, the droplets react with hot air instead of oxygen. So, as these droplets reach down the pool’s surface, they meet the existing warm water present in the pool. Thus, your swimming pool becomes even hotter. Therefore, you should activate the fountain sometime between evening and night to achieve effective cooling.

What Are the Different Types of Fountains Available for Pools in the Market?

If you keep the design aspect of the fountain aside for a moment, you only have a few options to choose from. Basically, the different types of fountains are all about location, where you want to install them. Therefore, the following list here includes some of the most famous types of fountains available in the market. Let us check them out one at a time.

  •  Poolside Fountain

These types of fountains are exactly what the name suggests. You have to install them just on the edge of your swimming pool. But the design choice is entirely dependent on you. So, choose a design that will perfectly blend with the surrounding environment. To make them work, you have to attach the return jet to an adapter. This is one of the most common methods of circulating the pool’s water. After that, you attach the adapter to the pipe to start the water flowing through the fountain. If you have set everything properly, the fountain should start splashing water.

  • Centerpiece Fountain

With a centerpiece fountain design, you need to install them in the middle of your swimming pool. Usually, these types of designs add a huge aesthetic value to your existing pool decoration. However, centerpiece designs are more difficult to install than your average poolside fountains. In some cases, you may need to remodel the entire swimming pool to incorporate this design.

  • Floating Fountains

These types of fountains have similarities with the poolside fountains. But instead of connecting the adapter to the pipe, you have to connect it to a hose. This will help you connect with the fountain that can float anywhere in your pool. Many people don’t prefer this type as a hose will constantly float around all the time. But this is one of the cost-effective methods of installing a fountain.

What Are The Downsides Of Installing A Fountain?

The following points will focus on some of the downsides of installing a fountain.

  • Fountain Installation Is Expensive

Most of us are already aware of this point. Once you decide to install a fountain, it will cost you a lot of money, even if your design requirements are very basic. And if you go with centerpiece fountains, the cost will rise even more.

  • They Only Perform Surface-Level Aeration

Fountains can only perform surface-level aeration. Thus, it will help you control the surface-level weeds and algae. But the bottom of your pool will remain cluttered. So, all these algae will sink down to make your pool dirty and unhealthy.


To conclude, we can say that fountains do keep your pool water cool to quite an extent. However, the trick is to choose the right fountain for your swimming pool to get the best results.
