The 9 Best Solar Heaters for Above Ground Pools of 2023

1. Game 4714 SolarPRO Contour Solar Pool Heater for Intex

Game 4714 SolarPRO Contour is one of the most popular solar pool heaters. Thanks to its compact size, this heater is eye-pleasing and super easy to install.

Heating Efficiency

This model is ideal for small above ground pools. It is capable of raising your pool’s temperature by 5 degrees in about six days. This way, you can maintain the pool’s temperature at the ideal warmth for everyday swimming.

For those who live in areas where nights are much cooler, you will need to add a solar cover. It prevents high heat losses which help keep the pool warmer than the outdoors.

Design and Installation

The dome-shaped design of this solar heater is its highlight. It creates a greenhouse effect to increase heat transfer. Although it has 90 days of warranty, its injection-molded construction lasts long.

When it comes to installation, it is a simple do-it-yourself situation. It includes the adapters for Intex and Best Way Pools. You will need a 1.5HP pump so that water can flow at an ideal rate. The included hose is quite short. If your pool is not located where there’s plenty of sunshine, you will need to invest in longer hoses.

Also, to effectively warm a large pool, two or more of these solar heaters are required. You may need to perform some modifications. For example, have a pump that filters the water and another that runs the warm water without a filter. This way, you won’t deal with a decrease in flow rate due to the filter.

2. Fafco Solar Bear Economy Heating System

Our second pick for the day is the Fafco Solar Bear Economy Heating System. It is a pricier solar pool heater owing to its large size and effectiveness.

This solar heater has two-inch headers. These headers are important for excellent heat transfer and consistent circulation. Solar Bear does not follow the standard transfer of heat, instead, water pumps through the heater and out again. It results in faster and effective heating.

It is recommended to run Solar Bear between 10 am and 4 pm, but we all know this is dependent on where you live. You may also want to tilt the heater south in a 30-degree angle for the best results.

Design and Installation

The only thing you have to deal with is the considerable amount of space it takes. If you don’t want to have dry grass patches, you’ll want to install it on the roof. But remember, this is not an install and forget device, you have to keep checking it from time to time.

You don’t want to depend on it if your area is prone to cold winds and very low temperatures. But you can complement it with a solar cover that will prevent loss in warmth during the night.

Design and Installation

Perhaps the most remarkable thing about this heater is the simple installation process. You will get four hoses, stainless steel clamps, and fittings. All you have to do is connect it between the pump and the pool return and you are set. The heater is compatible with both 1.25-inch and 1.5-inch flexible hoses.

It allows you to use it with longer hoses if you have to install it further from the pump.

The first thing you notice about SunQuest is the premium quality of the panels. They are large, making them efficient for heating medium and large-sized pools in a matter of hours. The SunQuest solar collectors feature copper absorber plates and Tefzel glazing. These features provide UV-resistance and durable performance.

This solar heater can raise your pool’s temperature by ten degrees. Most people who live in colder regions with only a few hours of sunshine will benefit from this model. Whether you lose 3 or 5 degrees of warmth overnight, your pool waters will always be comfortable.

Design and Installation

The SunQuest panels are flexible like mats. Although they are quite heavy, you won’t have lots of trouble mounting them. It is best to unroll the panels in the sun, they are pretty stiff when cold, but when exposed to sunshine, the warmth makes them a bit soft, so they are easy to unroll. Better still, it comes with a mounting kit and straightforward instructions.

After everything is set, you will enjoy the MAX-FLOW design. This design includes two-inch OD headers that improve water circulation. it is no wonder why it is capable of raising water temperatures in a couple of hours.

5. Sungrabber Solar Pool Heater with LiquidHeat Solar Blanket

The Sungrabber Solar Pool Heater looks like the SunQuest model, but instead of copper solar absorbers, this one uses polymer solar collectors. It is, thus, cheaper and lighter than its SunQuest cousin. However, you will have to wait a few days to feel any change in the water’s temperature.

Heating Efficiency

Sungrabber has received high ratings in its heating efficiency. The two panels have lots of tubes in comparison with solar heaters in their price range. As such, the panels can heat water fast and keep the temperature ideal as long as the system is running.

This solar heater works best with small above ground swimming pools up to 15ft round. Any larger and the heaters cannot meet the rise you need. In this case, you will require more panels which will take up more space. It is better to stick to the size recommendations.

Design and Installation

For a polymer solar heater, we are impressed by its efficiency. This model boasts compatibility with any pool pump. It is also mountable on a roof or rack, but most people agree it is best set on the ground. At the price, you can expect leaks after some time. Leaks are hard to repair on a roof than on the ground.

The installation is very straightforward, you only need the hoses, the pump, and the fittings. The only thing you’ll need to ensure is that the hoses can take the pressure of the water. Otherwise, you are looking at a blow-up in a matter of days.


Two panels offer reasonable heating.

6. Sun2Solar 800 Series Blue 15ft Round Solar Cover

Solar blankets are not your typical way of heating pool water, but if you live in warm areas, you don’t need to go all the way with a pool heater. The Sun2Solar may be what you need.

Heating Efficiency

Did you know that solar blankets prevent up to 95% of pool water evaporation? That is what the Sun2Solar is all about. Preventing water loss during the night means you will be filling your pool less frequently. This way, you won’t interfere with the water temperature, and you can go in with confidence.

The blue bubbles in the Sun2Solar are what makes this blanket different. It does not just prevent water evaporation, it also uses the sun’s rays to warm up the water. At night, the cover goes to work to prevent heat loss. You can depend on it to maintain the ideal swimming temperatures.

Design and Installation

This cover comes in a slim design which allows for fast rolling and unrolling when you enter and leave the pool. You still need an extra pair of hands to do the rolling and unrolling though. Also, it comes in different sizes; the 15ft round cover will only fit 15ft round pools, the same thing goes for 12ft, 18ft, up to 36ft.

If you have a pool, in a different shape, we recommend measuring the widest part and going for a cover that size. After that, you can cut off the extra material and it won’t void your warranty. That’s it for this solar heater since it does not require any form of installation. Just lay it on your pool and it is good to go.

This way, it can raise the pool temperature and keep it that way. Combined with a solar cover, you can use this mat solely to increase your swimming period by one or two months.

Design and Installation

The best thing about Intex Solar Heater is its small size. Measuring 47 x 47 inches, it is barely the size of a regular solar panel. It won’t take lots of space and installation is easy too. The mat works with hoses with up to 0.5HP and 1.25-inch hose attachments. It comes with the connecting hose and the bypass valve.

During installation, you will want to be careful of the pressure and the connections you make. This model relies on O-rings to prevent leaking. It also requires that you do not use a low-pressure hose to prevent busting.

What if you have a large pool and want to use as many Intex mats as possible. Well, in this case, you have to divert the water flow through different pipes. If not, you may end up with hose busts more often than not.
