Is Solar Pool Heating Worth It?

Having a pool in your house is a wonderful luxury. However, taking care of that pool takes a lot of effort and time. It can also be pricey, especially if you like your water at an optimal temperature even during the colder months. Heating your pool is one of the most complicated chores.

If you want your water to be pleasantly warm, but not spend a fortune, you have to find the most efficient way to heat your pool. Using a solar pool heater is one way to do it.

The question is – how well do solar pool heaters work? Let’s find out the answer together.

How Does A Solar Pool Heater Work?

It might seem complicated, but it’s actually not. Solar pool heaters work by using special rooftop or ground-mounted solar mats that are plumbed into the pool’s circulation system. During the day, when there is natural light, the sun hits those solar mats. The mats are designed to capture that heat from the sun.

This heat is then transferred into the water that circulates through the pool’s plumbing system. This causes the water in the swimming pool to slowly heat up over time. It’s safe to say that this is the simplest way to keep the water in the pool warm and pleasant during the colder months.

Things Solar Pool Heaters Can And Can’t Do

A lot of people want their swimming pools to be unusually warm at all times, almost like a hot tub. Now, even though this is a rather pleasant experience, especially during the winter months, it’s important to state that this can’t be done with solar pool heaters.

Why is that? Well, the answer is pretty simple, solar pool heaters can’t get the water temperature up to 82° or higher, which is the case in hot tubs. If you are looking for something like that, these pool heaters are not for you. Also, if you are the type of person who would like to heat up the water quickly on cooler days, this is probably not the best option for your swimming pool.

One of the most important things people have to understand about solar pool heaters is the fact that they are not designed to increase swimming pool water rapidly. On the contrary, they heat the water in a slow but consistent manner. The good thing is that this can be done even on cloudy days with partial sunshine. The best thing about the solar pool heaters is that they are perfect for maintaining a swimming pool temperature a little below 82°. This is good if you live in the south where the climate is mild and where the cold weather is rare.

It’s also important to state that the solar swimming pool heating system simply won’t work the same every single day. Why is this the case? Well, because the amount of available sunshine, wind speed, and ambient air temperature are all a factor when it comes to how efficient the rooftop solar pool heater will be every day of the week. There are no definitive answers regarding this topic, but let’s put it this way.

On a sunny day when the temperature is not below 50°, people who are using the solar pool heaters can expect the water temperature to rise 1° every four or five hours. This, of course, will be the case if they are using a rooftop solar pool heater. To be frank, this is enough heat to maintain most swimming pools at a very comfortable swimming temperature.

If you live in colder parts of the country, you might be wondering whether or not pool heaters can freeze. You will be happy to know that this doesn’t happen with solar pool heaters.

Why Are Solar Pool Heaters Good?

Other than the obvious eco-friendly factor, solar pool heaters are good because they can save you a considerable amount of money. Sure, if you want to install it properly, you will have to invest some money upfront, but this will pay off in the long run.

The best thing about solar pool heaters is the fact that they work even on cloudy days. They will keep the water in your pool at an optimal temperature and you will be able to use the pool at any time during the day and night.


Even though solar panels are not a new concept, solar pool heaters are. This means people have many questions regarding the use of those heaters. Here are some of the most common questions.

How Long Does It Take To Heat A Pool With Solar Panels?

As we said, solar pool heaters are not designed to heat the water in the pool rapidly. They do it slowly and steadily. Also, there are a lot of factors involved, like the weather, for example.

Let’s put it this way. A pool in Southern California that is using unglazed solar panels will warm up to pleasant temperatures (78° F to 85° F) in just a few days if it’s being used in spring. However, a similarly sized pool in New York will require a whole week to warm up. As stated before, those heaters won’t do a good job during colder months.

Is Solar Pool Heating Worth It?

The other concern pool owners have is, of course, the financial aspect. In other words – is the solar pool heating worth it? The answer is yes. Not only is this better for the environment, but it will save you a lot of money in the long run. You won’t have to use electricity or any other kind of fuel to heat your pool. This is definitely an investment worth making.


Having a pool in your backyard is a wonderful thing. However, maintaining that pool and keeping it warm are everyday chores. Those are the things no one talks about when it comes to swimming pools. Another thing no one talks about is the financial aspect.

Keeping a pool warm costs a lot of money, especially if you use electricity to do it. If you want a more financially viable option that is also eco-friendly, then you should definitely consider solar pool heaters. Sure, they are a bit slow, but if you arm yourself with a little bit of patience, you won’t have to worry about the water temperature or your bills ever again.

Also, the fact that you are taking care of the environment will provide you with a wonderful and rewarding feeling. Your only job will be to pour yourself a cocktail and enjoy a pleasantly warm pool.
