There are dozens of solar pool heaters available on the market, each with unique features, materials, and design aspects. Choosing the right one for your pool can be a complex task.

That’s why I’ve made the research for you, testing over 47 solar pool heaters, and weighing their efficiency, durability, and quality.

In this guide, I’ll walk you through the top picks, breaking down their features, benefits, and potential drawbacks.

Best Solar Pool Heaters Selection

Best for Above Ground: Intex Recreation Corp Solar Pool Heater


  • Material: Plastic
  • Flow Rate: Up to ½ HP
  • Temperature Increase: 5 to 9°F
  • Compatibility: Suitable for pools up to 8,000 gallons

The Intex Recreation Corp Solar Pool Heater is designed for above-ground pools up to 8,000 gallons with a pump flow rate of about 2,500 gal/hr.

This model also can increase the temperature of the water by approximately 3 to 5 degrees Fahrenheit over several hours of exposure to sunlight. 

I live in Los Angeles, California, where the sun shines abundantly but the nights can get quite cool, often dropping the pool’s temperature.

In my own yard’s pool, which holds a cozy 4,500 gallons, I’ve experienced this first-hand.

During a typical sunny summer day, the heater can elevate the temperature from a brisk 68 degrees Fahrenheit in the early morning to a more inviting 73 degrees by noon.

And when it starts to dip in the late afternoon, this heating system manages to retain some warmth at around 70 degrees, giving us many more hours of comfortable swimming.

I should also note that the package includes a bypass valve, 32mm hose attachment points, 1 adaptor A and 1 adaptor B for 11/2 in (38mm) hose connections, and a 0.5 m (32 mm diameter) connecting hose.

This made it easy for me to hook up the system to my existing pool setup without any professional assistance.

All I had to do was to find the proper location, right where the sun’s rays would hit the panel most effectively. 

At first, it was all going smoothly. I managed to hook up the 11/2 in (38 mm) hose connections and fit the adaptors. 

But then, a snag hit me. One of the 32 mm attachment points seemed faulty, and water started leaking, almost ruining the entire setup.

After some initial panic, I remembered the bypass valve that came with the package. I swiftly rerouted the flow, and the leak was stopped. 

I made some careful examination and a quick run to the local hardware store, I realized that a simple washer replacement would solve the problem. 

It cost me just under $3, and within 15 minutes, the installation was back on track.

Finally, after 3 hours of work, it was ready. The system was up, and I could already feel the warmth it was adding to the pool’s water.

You don’t have to worry about winter months when the pool isn’t in use, as this heater’s clever design allows for easy compact folding. 

I discovered that it could be neatly packed away, thanks to its heavy-duty UV stabilized PVC material that resists weathering. 

Once the summer rolls around again, it’s just a matter of setting it back up, and you’re good to go.

One issue I had with the heater was the short length of hosing. 

Although I had figured out a sunny spot that would work well, the short hose made it tricky to position just right. 

I had to wrestle with it a bit, and in the end, the place where it lay killed the grass underneath.

All in all, I still think that the Intex Recreation Corp Solar Pool Heater represents a sound investment for its easy installation, low price point, and adaptability to various pool sizes.

  • Warranty: 10-year

The Sunheater Solar Pool Heater integrates a clever tube-on-web design that not only enhances the system’s efficiency but adds to its longevity as well. 

Here’s how it works: by weaving heating tubes into a supporting grid, the Sunheater is able to cast a wide net to capture solar energy, channeling the sun’s rays directly into the water that flows through these tubes. 

This seamless transfer of heat warms up the pool’s water effortlessly.

But the design isn’t only about capturing sunlight. It also offers rigid flexibility, enabling the panels to expand and contract with fluctuating temperatures.

This blend of creative engineering and practical consideration has made a system that can heat your pool water by as much as 15°F, extending the swimming season without a drastic spike in energy bills. 

My parents have a spacious inground pool, measuring 18′ x 36′, nestled in the backyard of their suburban home in Rochester, New York.

At our family gatherings in Rochester, New York, the backyard pool was always a centerpiece of summer fun. 

Yet when winter’s chill set in, it would become a deserted, icy expanse, mirroring the freezing temperatures outside, so I decided to test this model.

I recall the day I installed it in late September, a period when Rochester’s temperature would start to dip into the 60s.

The morning after installation, I measured the pool’s temperature and found that the water had already warmed by nearly 3°F.

Over the subsequent days, I continued to monitor the water temperature, jotting down the numbers in my notebook. 

Within a week, the pool’s temperature had increased by 10°F, enough to make it comfortable for an early morning swim or a relaxing evening dip

As the weeks rolled on, the pool now has become a hotspot for winter swimming – it holds a consistent temperature around 75°F, allowing us to enjoy the pool even on brisk winter mornings.

The installation process also is a breeze. I grabbed the user’s guide, which is clear and concise, and laid out the panels, tubes, and connectors on my garage floor.

I started with laying out 16 tubes, each measuring 2 feet in length, which I had to assemble in a particular sequence.

Next, I focused on the supporting grid by arranging it according to the specified pattern in the manual, ensuring that each part was in its proper place.

Then I began attaching the tubes to the supporting grid, aligning them with the designated slots as shown in the manual. I used 8 stainless steel clamps for each tube, ensuring a firm and tight fit.

Once all the tubes were secured, I connected them to the pool’s existing pump system. The last step involved fastening the panels to the rooftop. 

With 16 anchor points and specific measurements for alignment, the whole process took around 3 hours.

The 10-year warranty provided an added sense of security, knowing that the company stands behind their product. 

I reviewed the warranty details, noting that it covered defects in materials and workmanship, reassuring me that the time and effort I invested would not go to waste.

The only gripe for me is the steep price point, making it a bit of a reach for those on a tight budget. 

The fact that the necessary tools aren’t included in the package also adds to the initial investment, forcing you to either purchase them separately or hire a professional.

However, I still think that the Sunheater Solar Pool Heater is the best choice for inground pools, especially for those in areas that experience significant temperature fluctuations.

What We Like

  • Efficient tube-on-web design
  • Warms pool by 15°F
  • Easy installation process
  • 10-year warranty

What We Don’t Like

  • Steep price point compared to other models
  • Necessary installation tools not included in the package

Best for Cold Climates: SwimEasy Solar Pool Heater


  • Material: Plastic

The SwimEasy Solar Pool Heater comes with solar panels made from high-grade polypropylene, a material known for its durability and resistance to UV damage.

The panels also have a protective coating that guards them against harsh weather conditions, chemicals in the pool water, and potential scratches.

In addition to the protective coating, the solar panels are enhanced with a network of heat-absorbing tubes that amplify the heating process. 

These tubes are filled with a special liquid that has the ability to quickly absorb and transfer heat. 

As sunlight strikes the tubes, the liquid inside heats up. This heated liquid then circulates through a system designed to transfer the heat directly into the pool water.

So whether it’s scorching summer or a biting winter chill, this model’s panels can always make the most of the available sunlight.

The heater also has wind vents that reduce wind resistance by permitting the free flow of air through specific channels. 

This design helps mitigate the force exerted on the panels, minimizing vibrations and the potential for wear or damage. 

Consequently, the heater can consistently operate at its optimal capacity, even in regions where powerful and gusty winds are usual.

I tested this model at a friend’s pool in the challenging climate of North Dakota, where temperatures can plummet to as low as -30°F and wind speeds can reach up to 40 mph.

Over a 3-month trial period during the winter, I carefully documented every fluctuation, efficiency rating, and weather condition to truly evaluate the heater’s performance.

The pool started at an initial temperature of 58°F. We set a goal to maintain a comfortable swimming temperature despite the challenging weather conditions.

During the first month, the heater managed to elevate the pool temperature to a consistent 68°F, even when the outdoor temperature plummeted to -20°F

The average heating efficiency remained at 85%, showcasing the effectiveness of the wind vents in reducing wind resistance.

In the second month, we faced a series of strong wind storms with speeds up to 45 mph

Thanks to the heater’s design, the pool’s temperature never dropped below 65°F, and the efficiency stayed relatively steady at around 82%.

The third month brought mixed weather, with some sunny days but mainly cloud cover and snow. Yet, the pool’s average temperature was maintained at 67°F with a minimal fluctuation of 2°F.

The model is also packaged with UV-resistant EPDM rubber couplings, stainless-steel brackets, and hose clamps, flashing bases for enhanced seals, and high-strength woven polyester for hold-down strapping.

And if you’re starting the installation process from square one, no sweat, you’ll only need to get a couple of additional valves to tie into your pool equipment.

To get the system together, I’d grab a check valve, a 3-way diverter valve, and a couple of isolation ball valves.

As for the installation process, I started by laying out the precise locations for the solar panels. 

I knew that exposure to sunlight and wind patterns would be essential, so I took the time to study the manual carefully. With my toolkit, measuring tape, and a borrowed drill, I kicked off the project.

Day one was all about assembling the panels and setting up the connections. 

By the time the sun was setting, I had managed to secure the solar panels with the brackets and hose clamps, ensuring proper alignment which took me 7 hours.

Day two was all about the integration of the additional valves. 

The task was intricate – I had to carefully fit the check valve, 3-way diverter valve, and isolation ball valves. 

With some trial and error, I aligned the valves to the existing pool equipment in 5 hours.

To make sure that all the connections were secure, I used a pressure-testing kit, slowly pumping air into the system to simulate the pressure of water flow. 

By watching the gauge carefully, I could verify the integrity of every joint and seal. 

Anywhere that a slight dip in pressure emerged, I knew a potential leak lurked. I sealed those with additional tightening and, where needed, I applied plumber’s tape. 

However, the installation process can be a bit overwhelming. 

Although the manual guided me through the maze, I faced some challenging hours piecing everything together. I had to double-check every joint and coupling. 

If you’re a novice, you might reckon it’s a tough journey. Still, with patience and perseverance, you can absolutely do it.

All in all, this model’s efficiency, resilience against extreme weather conditions, and its ability to adapt to various sunlight conditions make it an investment worth considering.

What We Like

Best Roof Installed: XtremepowerUS Solar Pool Heater


  • Material: Plastic
  • Flow Rate: Up to ½ HP
  • Warranty: 3-month

The XtremepowerUS Solar Pool Heater features a powerful pump of up to ½ HP, enough to fill the heating needs of various pool sizes.

Whether it’s an above-ground pool that measures 12 x 24 feet oval with an area of 257 square feet, needing only one panel, or a larger 27-foot round pool requiring 2 to 3 panels, this model is perfect. 

And for those with ovals reaching 18 x 33 feet and 524 square feet in space, 3 panels are sufficient. 

Furthermore, for round pools, the range starts from 10 feet, requiring just one panel, extending up to 24 feet in need of 2 panels.

Just a few months ago, I undertook a major project for the community recreational center that was seeking an energy-efficient and cost-effective solution for its large swimming pool. 

This was not a simple task, as their pool was a substantial 18 x 33 ft. oval, covering an area of 524 square feet, so I felt that this model could match the specific requirements.

I also chose it for the fact that it’s installed on various surfaces such as roofs, sheds, or cabanas, and can even be mounted on a rack or placed directly on the ground.

This decision not only provided optimal exposure to sunlight but also avoided any disruption to the surrounding landscape or recreational areas.

The dimensions of the solar panels, being 2 feet by 20 feet each, ensure an expansive surface area for absorbing sunlight.

This in turn allows for more efficient heat absorption, leading to quicker and more effective warming of the pool water.

I made notes for a span of 45 days, marking down temperature variations, the efficiency of panels, and the overall performance of the heating system. 

During this assessment period, the pool temperature experienced an average increase of 7 degrees Fahrenheit when the sun was out in full force. 

Even on overcast days, the pool still managed to gain 3 to 5 degrees, proving the system’s resilience.

As for the cost-saving aspect, the recreational center noted a decline of around 20% in monthly heating bills, translating to substantial yearly savings. 

There was an unexpected boost of 40% in pool attendance during chillier months, which is a relief for the community manager who had been grappling with low usage rates during those seasons.

The heater comes with 2 x combination hose adapters, measuring 1.5″ and 1.25″ each, that allow for a snug fit with various hose sizes. 

In addition, 2 x “O” rings are provided for secure sealing, and 2 x end caps are included to neatly finish off the connections. 

A roll of Teflon tape assists in making waterproof seals where required, and an in-depth installation manual for a smooth and precise installation process.

To set the system up, I turned to a couple of trusted hands in the field, two local experts who’d worked with me on past projects.

We first conducted a careful examination of the recreational center’s roof, noting its slope, condition, and orientation with respect to the sun.

Then we mapped out the exact locations for the brackets that would support the 2-foot by 20-foot solar panels; following this we we drilled holes and secured the brackets.

Once the brackets were in place, we proceeded to mount the hefty panels, relying on teamwork and coordination to set them just right.

After that, we used the provided accessories to make all the connections: the combination hose adapters fitting precisely to various hose sizes, the “O” Rings ensuring a tight seal, and the end caps giving a neat finish. 

The roll of Teflon tape came in handy for wrapping the joints meticulously, thus achieving vital waterproofing.

I also appreciate the 3-month warranty that comes with the system; it gives me peace of mind knowing that if any part shows a defect, I’ll have support from the manufacturer. 

In fact, during installation, we discovered a minor issue with one of the “O” Rings – it appeared slightly warped and didn’t provide an adequate seal.

So we gave the customer service team a quick ring, explaining the situation, and the next day a new “O” Ring arrived at our doorstep.

One problem is that the mounting slots are stamped only on one edge of each panel, rather than across both the top and bottom. 

This design limitation restricts the mounting options such as allowing for various angles, positions, or configurations tailored to the roof’s structure.

Still, I think the XtremepowerUS Solar Pool Heater offers a reliable option for roof installation, catering to diverse pool sizes and shapes.

What We Like

  • Powerful pump of up to ½ HP
  • Suitable for various pool sizes and shapes
  • Smooth installation
  • 3-month warranty

  • Temperature Increase: 5°F
  • Compatibility: Suitable for pools up to 8,000 gallons

The GAME SolarPRO Curve Solar Pool Heater is compatible with both above-ground and most in-ground pools of up to 8,000 gallons.

And don’t get fooled by its curved shape; it’s not just a design quirk. 

This unique curvature creates an expansive solar collecting area, harnessing free heat from the sun as its position changes throughout the day. 

In turn, this allows for a temperature elevation of up to 5°F in 4 days, transforming a chilling swim into a comfortable experience.

Last year, I tested the GAME SolarPRO Curve Solar Pool Heater at my neighbor’s above-ground pool, a medium-sized installation holding around 6,500 gallons.

It was autumn, a time when the outdoor temperatures were beginning to dip, and the prospect of a warm swim seemed all but lost. 

The initial pool temperature hovered around a cool 60°F, hardly inviting for a relaxing dip.

After setting the system up, I tracked the temperature changes closely, recording daily readings to gauge the heater’s performance.

The first day showed a modest increase of 1°F. I thought it might be a fluke or a result of the day’s weather, but I kept tracking. 

By day two, the increase was 2°F more. By the third day, it was clear that the heater was doing its job, and by the end of day four, the water was 5°F warmer, reaching 65°F.

The model also features threaded ports, providing flexibility and ease for various plumbing setups. 

For example, these ports allow for flexible connections, fitting different types of hoses and fittings. 

Whether you’re dealing with an above-ground or in-ground pool, a small personal setup, or a more elaborate configuration, this feature ensures that integrating this heater will be a simple process.

For our specific setup, my neighbor had an older, non-standard hose that we initially feared wouldn’t fit. 

However, the threaded ports turned out to be a perfect match, allowing us to connect the heater effortlessly.

One drawback is that the solar panel can be a bit small. 

Although it’s designed to capture as much sunlight as possible with its unique curve, the actual surface area might not be sufficient for larger pools.

Overall, the GAME SolarPRO Curve Solar Pool Heater proves to be a strong option for its sleek design coupled with the curved shape that allows it to harness the sun’s energy effectively.

Best Solar Cover: Sun2Solar Blue Solar Heater


  • Material: Resin

The Sun2Solar Blue Solar Heater is a blanket made from a resilient resin material with thousands of tiny bubbles, each acting as a solar energy collector. 

These tiny bubbles work collectively by trapping the sun’s rays and converting them into heat. 

As sunlight penetrates the blanket’s surface, the air-filled bubbles absorb the solar energy and transfer it directly to the pool water.

Not only do they enhance the water’s warmth, but they also prevent up to 95% of water evaporation, conserve pool chemicals, and shield the pool from debris.

I use this model on my chalet’s outdoor pool, located in the hilly region of Asheville, North Carolina, where it is kidney-shaped and holds around 5,000 gallons of water. 

In this area, the sun graces us with its presence quite generously during the day, but the temperature often plunges at night, causing the pool water to turn icy cold. 

This drastic temperature fluctuation was making my early morning swims a shivering challenge and significantly contributing to water loss due to evaporation. 

The constant refilling was a chore I grew tired of, not only taking time out of my weekend but also adding to my water bill. 

With each refill, I had to adjust the chemicals, putting in extra effort to maintain the perfect balance for safe swimming.

However, after a while of using this model and tracking the effects, I observed a remarkable change in my pool maintenance routine. 

The once frigid early morning swims became much more comfortable with a consistent water temperature of 78°F

Additionally, the water loss due to evaporation decreased by about 75%, a saving that positively impacted both my water bill and the environment. 

The requirement to refill the pool, adjust chemicals, and balance the water quality lessened by 60%, saving me hours of work

What I love most is that I can easily trim the cover to fit the unique kidney shape of my pool, ensuring optimal coverage and efficiency. 

This tailor-made fit not only enhances the visual appeal but also maximizes energy absorption, leading to even faster heating. 

In fact, I recorded a 20% increase in heating efficiency compared to using a standard, non-customized solar blanket.

I only wish that the sides were more resistant to tearing. 

In my attempts to keep the cover secure against winds, using clamps or clips, I accidentally caused a slight rip.

Despite this minor drawback, I still recommend the Sun2Solar Blue Solar Heater to anyone looking to enhance their pool’s warmth, conserve water, and shield their pool from debris.

What We Like

  • Captures sun efficiently
  • Versatile with pool shapes
  • 95% evaporation prevention
  • Reduces maintenance

What We Don’t Like

  • The sides can be torn easily

How Do Solar Pool Heaters Work?

Solar pool heaters operate by harnessing the power of the sun, converting solar energy into heat for warming the water of a swimming pool. 

The initial part of this heating process involves solar collectors which are sually placed on a rooftop or other sun-drenched location. 

Through their surface, they channel water, allowing it to gain temperature by absorbing solar energy.

The water in the swimming pool is pushed by a pump through a filter, clearing it from debris and impurities. 

The filtering process is critical for maintaining the functionality of the system, as any foreign materials could hinder the operation of the solar collectors. 

Following filtration, the water moves to the solar collectors, guided by a carefully controlled valve system.

Inside the solar collectors, the water is heated by the sun’s rays. The dark, absorbent surface of the collectors traps sunlight and converts it into thermal energy. 

The design of the channels within the collectors helps quick and effective heating, with the thin structure allowing for efficient heat transfer.

Once heated within the solar collectors, the water returns to the swimming pool. 

This warm water then mixes with the cooler water already in the pool, gradually increasing the overall temperature of the water. 

This cycle continues as long as the solar collectors are receiving sunlight, providing a consistent and comfortable water temperature for swimmers.

How to Choose the Best Solar Pool Heater?

1. Consider the Pool Type You Have

One of the most important factors in selecting the best solar pool heater is to consider the type of pool you have. 

Different pool designs demand distinct heating solutions, and choosing the wrong one can lead to inefficient heating or even damage.

If you have an above-ground pool, your options might include lightweight and easy-to-install solar heaters designed specifically for such pools. 

For instance, our pick, the Intex Recreation Corp Solar Pool Heater, can be a perfect fit for this purpose.

On the flip side, if you possess an in-ground pool, you might prefer a more robust solar heating system. 

In-ground pools often have larger water volumes and require more sophisticated heating solutions. 

In this case, you might look into solar collectors that are installed on the roof or other elevated surfaces, connected through a series of pipes to the pool’s filtration system such as SunHeater Solar Heater.

That’s why I’ve included options for both in-ground and above-ground pools, and also solutions that can work for both types. 

Thus, you can make an informed decision based on the specific characteristics of your pool.

2. Find out the Size of Your Pool

Knowing the size of your pool determines a lot of factors in the selection process such as the type of solar heater, the number of solar panels, the appropriate pump flow rate, and the overall efficiency of the system.

For small above-ground pools, a basic and lightweight solar mat system may suffice. 

These systems are often paired with pumps that have a lower flow rate, yet they can effectively circulate the water through the heating system. 

They are usually designed for ease of installation and to provide a moderate increase in water temperature.

In contrast, larger in-ground pools may demand a more robust solar heating system. 

The number of solar panels and the size of the pump must be carefully matched to the pool’s volume. 

You’ll also need a pump with a higher flow rate to move the larger volume of water through the solar collectors, converting the sun’s rays into heat efficiently. 

It might also need more intricate installation procedures and have an impact on the operating cost.

I’ve made sure to include in this list options that cater to various pool sizes and types, ranging from compact, easy-to-install systems for small above-ground pools to more complex solar collector systems for larger in-ground ones.

3. See How Much Sun Your Pool Gets

The amount of sunlight your pool gets will determine the type, size, and efficiency of the solar heating system you’ll need. 

In locations where the sun shines brightly and consistently, a smaller and less complex system might be enough.

However, in places where the sun tends to hide behind clouds or the pool is often shaded by trees or buildings, a more robust solution is likely in order.

Finding out the angle at which the sun hits the pool area is also important. 

It helps in deciding the placement of solar collectors to maximize the absorption of solar energy. 

For example, if you live in the Northern Hemisphere, you’ll need to place the solar collectors facing south to take full advantage of the sun’s path. 

In contrast, if you reside in the Southern Hemisphere, the collectors should face north.

Seasonal variations play a big role too. 

If you live in a place that gets bountiful sun during the summer but very little in the winter will need a different approach compared with an area that has a more consistent sun exposure year-round. 

In case of dramatic differences in seasonal sunlight, you’ll need to invest in a system that you can easily adjust or augment depending on the time of year.

However, in places where the sun gives a steady performance throughout the year, you’ll only need a consistent and well-balanced system, not requiring the same level of adjustments or augmentations.

4. Consider the Material & Quality

Like any solar heating solution for your pool, the material and quality of the components are crucial factors that determine not only efficiency but also the lifespan and reliability of the system.

Most solar panels or collectors are made from materials like copper, aluminum, or even specialized plastics, such as EPDM, polypropylene or polyethylene.

Each of these options carries distinct features that must be carefully weighed before making a decision.

Copper, known for its exceptional thermal conductivity, stands as a top-tier choice for efficient energy transfer. It’s also corrosion-resistant, promising a long-lasting and reliable performance.

Aluminum, although less effective in thermal conductivity than copper, brings its own charm to the table. 

With its lightweight nature and lower cost, it’s suitable for scenarios where budget considerations or weight restrictions are present.

Specialized plastics like EPDM, polypropylene, or polyethylene are popular due to their UV resistance and compatibility with pool chemicals. 

EPDM is particularly favored for its flexibility and weather resistance, making it a robust choice. 

Polypropylene and polyethylene, on the other hand, are often opted for their affordability and relative ease of maintenance, although they may not be as durable as other materials.

The quality of the installation tools such as the mounting hardware, pipes, and connections, too, is important to consider. 

This isn’t just about the longevity of your solar heating system. It also impacts efficiency, safety, and overall performance.

I’ve tested every item on this list and made sure that they all meet a certain quality standard and won’t face any trouble during installation, shipping, or even regular use.

8. Examine Warranty

You should always look for a solar pool heater that has some sort of warranty. 

The thing about warranty is that it essentially acts as a confidence statement from the manufacturer. 

It’s a clear signal that they stand behind their product, ready to provide support or replacement if something goes wrong.

Most often, you’ll find warranties that cover the collector or panel themselves. 

Others might extend coverage to the pumps, controllers, or even the installation process. 

But it’s not just about the duration of the warranty. You must also take into account the terms and conditions. 

Some warranties cover all aspects, while others might have a pro-rated system where the coverage reduces over time.

Reading the fine print and understanding what’s included in the warranty — and what isn’t — will keep unpleasant surprises at bay. 

Also, know who will handle the warranty claims: the manufacturer, distributor, or the installer.

That’s why in this guide, I’ve made it a priority to include solar pool heaters that offer at least a 30-day money-back guarantee

So you can try them out, experience firsthand how they function in your unique setup, and make a more informed judgment.
