• Solar panels on a home in Tampa, FL


Anyone who has ever tried to swim in a cold pool knows that it can be quite a shock to the system. Solar pool heaters are a great way to keep your pool at a comfortable temperature, even during the colder months.

Solar pool heaters work by using the sun’s energy to heat your pool, which can be a more cost-effective solution than traditional heating methods. Solar pool heating systems are relatively easy to install and require little maintenance. As an added bonus, they can extend your swimming season by several weeks—or months, in some areas.

If you’d like to know how solar pool heaters work, read on to learn more.

Benefits of Having a Solar Pool Heater

A swimming pool is an expensive investment, so it makes sense to look for ways to get the most use out of your pool. We’ve listed the benefits of having a solar pool heating system below:

1. Cost-Effective

Since solar heaters use the sun’s energy to heat your pool water, they can be a much more cost-effective option than traditional heating methods or electric pool heating systems.

Solar heaters can still be a great option even if you live in an area with limited sunlight. They use a network of solar panels to collect and store solar energy. This energy is then used to heat the water in your pool. 

2. Improved Swimming Experience

In-ground or above-ground pools can be very cold in the mornings or late evenings. With a solar pool heater, you can enjoy a warm pool whenever you want to take a dip!

With solar-heated pool water, you can also extend your swimming season (without added heating cost) to enjoy your pool for longer.

3. Low Maintenance

Solar pool heater installation only takes a few hours, and most systems require no maintenance once they are up and running. This means you can enjoy your pool without worrying about the upkeep.

Simply keep your solar pool heater clean, and ensure that any trees or other obstructions do not block the sun’s rays.

4. Eco-Friendly

Lastly, using a solar system to heat your pool is a great eco-friendly choice. By using the sun’s energy, you are reducing your carbon footprint and helping to protect the environment.

You can rest easy knowing that you’re doing your part for the planet while still enjoying your heated pool!

7 Steps on How Solar Pool Heater Work

Solar pool heaters use the sun’s energy to warm your pool instead of relying on fossil fuels like natural gas or propane. Here is a step-by-step guide explaining how solar pool heaters work:

1. Solar Panel Installation

The first step is to install solar panels on the roof or in an area that receives direct sunlight most of the day. These panels will collect and store solar energy, which will be used to heat your pool.

Skymark Power recommends using high-efficiency panels to maximize the efficiency of your system. Our team of professionals can help you determine the best panels for your needs so you can enjoy a comfortable pool for years to come.

2. Pump and Filter

A pool pump and filter circulate the water through the solar panel system. The pump will draw water from your pool, pass it through the filter, and then send it back into the pool once the sun’s energy has warmed it.

Debris and other particles can clog the solar panel system, so keeping the filters clean and changing them regularly is important.

3. Solar Controllers

The solar controller is possibly the most crucial component of a solar heating system.

Essentially, water from your pool goes into a series of valves that are connected to the solar controller.

The controller is then responsible for regulating how much energy gets stored in the panels, as well as when and how that same energy will be used to heat your pool.

4. Solar Panel Bottom

As the water flows into the bottom of the panel and rises up to the individual collector pipes, it is slowly heated by the sun’s energy. This makes it possible for your pool to reach temperatures up to five degrees warmer than the outside temperature.

5. Sun’s Heat

The water absorbs the sun’s heat as it rises to the solar collector tubes. This will help to heat the water as it is circulated through your pool.

6. Water Transfer

The water is then transferred to the pool’s filter system and back into your pool, raising the temperature of the entire body of water. The process continues until the desired temperature is reached.

7. Enjoy Your Pool!

Finally, once your pool is heated to the desired temperature, you can enjoy it without worrying about a drop in temperature. Your solar-powered pool heater works 24/7 to ensure your swimming experience is always comfortable and enjoyable.


A solar water heater is a great choice for anyone looking to heat their pool with an eco-friendly option. Not only does it help reduce your carbon footprint, but it can also save you money on your energy bill.
