The best solar pool heater should ultimately serve its function and deliver what it is meant to do, which is to warm and heat your pool to your desired temperature in the most efficient way, and that is using the sun’s solar energy without the need for any intervention from you.

How Do Solar Pool Heaters Work

The use of solar panels is the most cost-effective way of warming up pools. A solar pool heating system works by pushing water through a succession of pipes commonly referred to as the solar collector or solar absorbers generally attached to the ground or rooftop of the house or building. The solar energy from the sun then heats the circulating water. Once the water travels back to the pool, it is already warmer.

For better understanding, the solar collector or absorber pretty much works like a garden hose. When it is left lying on the ground under the full sun, notice that when you turn on the tap, the water that comes out is warmer or sometimes even hot. It is due to the hose absorbing all the sun’s energy, including the heat, and it transfers this heat inside the water inside the tube. It is the exact principle that happens with solar pool heaters but on a more prominent aspect. These are the simplified steps on the workings of these heaters.

  • You set your desired temperature for your pool. The sensor identifies when the solar pool heater gets activated so the heating process can start.
  • The pool pump will then push cold water from the pool and through a sequence of tubes in the solar collectors or solar absorbers.
  • The solar collectors will then utilize the solar energy to heat the cold water as it moves and flows through the panels. It then eventually returns the water to the pool at a higher temperature.
  • The solar warmed pool goes through the same process until the sensor detects that it has met the temperature that you initially set.

Note that for this to work, you must ensure that your solar collector is set in an angle and in the most suitable location where it can absorb as much solar heat as possible. It is the key so that the whole process can be successful, and you can enjoy your heated water.

What Are The Different Types Of Solar Pool Heaters


All solar pool heaters follow the same principle of water being pushed out of the pool for it to flow through the system pre-heated by the sun and then circulated back into the pool. Still, there are different types of solar pool heaters based on how they operate.

  • Evacuated Tube Collectors – this is considered as one of the most effective solar pool heaters, although more expensive than the thermal solar collectors. With a higher price tag comes higher reliability at the collection of heat even in colder areas. This type of solar pool heater uses a system of small glass tubes enclosed in larger glass tubes, so a vacuum is created between the two. As the sunlight warms the glass, the heat is confined within the vacuum and then transferred to a heat exchanger connected to the water box. The water is then warmed and heated in the heat exchanger before it flows back to the pool at a higher temperature.

Some would prefer ETCs because they are proven and tested to be more reliable. They can provide you optimum performance and output even if the temperature is freezing. Initial set up and installation for this kind of solar pool heater though, might be a little complicated.

  • Thermal Solar Absorbers – this is the most common one being used and widely available on the market. For this type, the solar panels are strategically placed on the roof of the house, or sometimes it is settled just near the pool. It is pegged as the most budget-friendly among the solar pool heater choices. Thermal solar absorbers can be classified as glazed and non-glazed.

Non-glazed is made from rubber matting. Sometimes, it is also made from plastics. The water is pushed over the collectors through a sequence of pipes. Thermal solar collectors are highly recommended if you live in sunny and warm regions as they are not as efficient in colder temperatures. Glazed solar pool heaters are deemed more competent as it is made of toughened glass, aluminum, and copper. They are more expensive compared to the ones made of plastic. They are a sensible choice for those living in the cloudier and colder areas.

The advantages of solar thermal absorbers are they are cost-efficient and easy to install. You also have a lot of choices, and it can be mounted on the ground near the pool. A downside though for this type of solar pool heaters is that some units may not be advisable for bigger pools.

Advantages And Disadvantages Of Using A Solar Pool Heater

A solar pool heater comes with a lot of benefits. Gone are the days where you must wait for summer, and you allow the change in season to dictate your pool time fun. On average, pool owners just get to enjoy using the pool for a maximum of four months every year, and the remainder will only serve as a decoration or accessory. With a solar pool heater, you can get a few more months to enjoy your pool and make the most out of it.

Another advantage of using a solar pool heater is you get to help the environment while having fun. A solar heater is the greenest way to get your pool’s temperature convenient for swimming, and it cuts its carbon footing.

The only drawback to these heating devices is that their efficiency in heating the pool water is dependent on the sun’s energy. It is why you need to install it in a place where it can garner enough sunlight to heat the pool. Nevertheless, it will not be hard to determine at all.

How We Picked And Tested


Choosing the right solar pool heater needs a lot of thought and consideration. Sure, you want one, but you must make sure that it can serve its purpose well. Here are some factors before you pick the most ideal one.

  • Climate – since the solar pool heater relies on the amount of sunlight it collects from the sun, then you must consider your location. Places, where it is usually sunny like Florida and California, are a sure win. However, if you are in the cooler and cloudier areas, you might consider the output you get from solar pool heaters.
  • Pool Size and Form – bigger pools would require more heat, so your solar pool panel, specifically your solar absorber or collector, should be fitting. Your solar collector area should be able to cover at 80% to 100% of the pool size in meters squared. You also must consider if your pool is above ground because this pool is easier to heat. Also, what is the primary purpose of your pool? Leisure pools, compared to exercise pools, would have different acceptable temperatures because, for exercise pools, it must be cooler so you can promote locomotion and circulation.
  • Roof stability – this is important because the solar absorbers are placed on top of your roof, so can your roof hold on to this material for a long time? You must ensure the construction and stability because this is where the collection of the sun’s energy is happening. You can install some reinforcements if needed before getting your solar pool heater system.
  • Accessories – sometimes, it is not enough to just have the basic solar pool heater system and to help boost its performance, choosing some accessories might be necessary. These add-ons are not mandatory but can be beneficial. It would be better if it comes in a package with the primary system. A solar cover and a solar cover reel are highly recommended auxiliaries since it helps with maintain the heat and in placing and removing the pool covers.

When shopping for solar pool heaters, there are a lot of excellent choices. If budget is not an issue, then the advantages that you enjoy are limitless and not to mention getting the highest quality possible. It all comes to your needs and wants.

Frequently Asked Questions


How many solar panels does it take to heat a swimming pool?

The number of solar panels for pool heating depends on your swimming pool’s surface area, location, and pool heating requirements (time length of pool use).

Experts recommend a 50 to 100 percent solar panel pool heater offset relative to the pool’s surface area.

  • For example, a 10’×20’ swimming pool has a total surface area of 200 square feet. Fifty percent of that is 100 square feet.
  • If a single solar panel for inground pools measures 4’x5’ (20 square feet), you will need five solar panels to cover 50% of the pool.

A 50% offset is enough to keep the solar pool warmer for 3 to 4 months.

If you want to swim in the pool for up to 6 consecutive months, you can increase the offset to 80% (eight solar panels in our example).

Homeowners wanting to keep their swimming pools open for 10 months should target a 100% solar offset (or 10 panels in our example).

It will be impossible to run a solar pool heating system all year round if you live in cold climates. Hence, keeping a 50 to 80 percent offset is usually good enough.

What pipe size is good for the solar heater?

A DIY solar pool heater with four solar energy collectors or less requires pipes with a 0.75-inch diameter. A one-inch diameter pipe is suitable for pool warmer solar systems with eight collectors.

The pipe size is also determined by the desired flow rate, measured in gallons per minute. So a 0.75-inch pipe will be most suitable for a maximum flow of 4 GPM, whereas a 1-inch tube can facilitate 14 GPM.

How long does a solar pool heating system last?

The US Department of Energy states that a thoughtfully designed and constructed heating pool with solar panels can last a decade or two. For example, a UV stabilizer-treated polypropylene solar dome pool heater should continue heating the pool for the next 15 to 20 years.

On the other hand, portable solar pool heater rings have a shorter lifespan than fixed systems. Generally, most of these heater rings for above ground pool units might only last a year or so.

How do I keep my solar pool heater from freezing?

The top-tier way to keep a solar pool heater from freezing is to keep the water circulating. Water freezes if it becomes stagnant or does not move along a conduit. If nobody is going to use the swimming pool because it is 10 degrees Fahrenheit outside, it will be top-rated to winterize the system.

To do so, completely empty the solar pool heater via the drain plug. Don’t forget to disconnect all plumbing fixtures connecting to the heater. If there’s still water inside, the liquid can form ice. As water will expand by 9% when it freezes, it can damage the heater’s integrity.
