Top Best Solar Pool Heater Reviews 2020


Many people may be put off due to the price. However, when it comes to considering the features it brings, you will find it cost-efficient. As our forefathers said, “You get what you pay for.” It does not have the name “High Performance” for nothing. 

First and foremost, it is designed to last. Made from polypropylene, it can stand against UV light, harsh weather, and outside debris. That being said, a SOLARPOOLSUPPLY Solar Pool Heater can last up to 15 to 20 years, depending on how you use and how you maintain the panels. 

Secondly, as it is constructed with rubber tubes, it can stand against expansion and shrinkage because of heat rise and heat loss. What’s more, there is a direct tube that provides a balanced current, avoiding concentrating heat at one point, so your pipes will last longer. If this, combined with being long-lasting, does not make SOLARPOOLSUPPLY the best solar pool heater, I don’t know what does anymore. 

Finally, in terms of setup and installation, we can assure you it is another good point. When you purchase the pack, it includes everything that you may need to put it onto the roof, such as strappings, pumping pipes, and connectors. Because of that, there is no need for the extra cost, but you can still have a warm and relaxing swimming session. 

The only thing that people complain about is the price. But compared to the variety and abundance of features that consumers get on purchasing, it is reasonable.

Kokido Keops

At under 150$, Kokido Keops can pride itself on being the best in this price range, despite falling behind compared to others at higher prices. It does not require a lot of space and does not cost anything except for product price. 

Although it does not cost as much and does not have huge solar panels, its heating efficiency is not inferior to others twice its price. At such a low price, your swimming pool temperature goes up by at most eight degrees. While at twice this price, some cannot even heat pool water by up to 10. Therefore, there is no need to doubt the cost-efficiency of Kokido Keops. 

Moreover, Kokido Keops is easy to connect to the pool pumps with no need for adapters. Although it is made for pools at 4000 gallons, you can connect two or three pieces or use a bypass kit to heat a larger pool. This way, your swimming pool water temperature will get hotter.


  • Relatively low price
  • Cost-efficient
  • Does not take up a lot of space
  • Connectible with a variety of pool pumps 


  • Temperature does not go up very much. 
  • Additional parts not included.


Not taking a lot of space, Goplus Solar Dome Swimming Pool Heater may not be the best. Still, its performance is not inferior to any other models, especially to fellow dome heaters.

Being a small size, this solar heater is designed for small to medium pools. So if your pool is more than 6000 gallons, consider purchasing two or three pieces or choose another model. 

It is also pretty easy to set up. Like most compact solar pool heaters, it does not require any professional knowledge to install. Also, it is inexpensive. If you want to enjoy a pleasant and relaxing swimming session but do not have much money, this is your best model.


  • Does not take up a lot of space
  • Suitable for small to medium pools
  • Easy to install
  • Very much affordable 


  • Temperature only goes up only by about three to five. 


Another option for the lazy installer is the solar pool cover/heater. There is no adapter, no pool pumps, no wire. All you need to do is pull out this bubbly mattress to cover all of the pool and wait for the swimming pool water temperature to go up gradually. 

This product comes in different shapes and sizes. Therefore, any pool size can fit into this cover. Moreover, manufacturers are very general. There are usually a couple of inches of oversize in every product, so you can trim it or fold the corners so that it fits perfectly well with the pool. 

Because it applies passive heating, the temperature goes up not very much and also very slowly. Therefore, do not use this as your main heating method if you are not ready to wait.


  • Generous sizing
  • Wide variety of size and shape to fit your pool
  • Retain heat, minimize evaporation 


  • Prolonged heating

Steinbach Speed

Usually, users have to wait for the swimming pool water temperature to gradually go up until they reach their wanted heat. But with Steinbach Speed 49120 Solar Pool Heater, this is not the case. It does not get the title of the best solar pool heater in fast heating for nothing. 

The most exciting and beneficial feature of this solar pool heater is the heating speed. On average, it heats the pool water by about two degrees per day. But on sunny days, this number may reach three or four and would take much less time. 

However, it does not restrain heat very well. After about 5 or 10 minutes, users notice that the water cools down. It is advisable to apply a timer along with the pool heater and set the time for every fifteen-minute to keep the pool at the wanted temperature.


  • Fast heating speed.
  • Panels are made from polyethylene, which can last very long.
  • Detailed and straightforward instruction 


  • Does not maintain heat very well

Solar Sun Rings

Designed to keep your pool warm enough for a swimming session in the afternoon, the Solar Sun Rings has a double layer. This double layer can stand against UV rays from the Sun. However, it does not mean the sunlight cannot touch the water. If it cannot, how can the pool be heated?

In terms of design, it does not have one representing design, according to manufacturers. However, it does have standard patterns, such as the yellow to the orange sun with a palm tree. But however it is designed depends on the time you buy it. 

There are warnings from the manufacturers. Do not over-inflate it. Blow them enough, which means just a few times. It cannot help you float on the water, as it is not strong enough. And finally, it is very light, so beware of strong winds. 

Many people have used one tip to buy about 5 or 6 pieces of Solar Sun Rings, depending on your pool size. In that way, many parts of your pools will be heated simultaneously, saving the heating time and increasing the heating speed. They also cover a much larger part of your pool than one piece can, stopping evaporation and preventing external factors at a larger scale.


  • Attractive design, especially to children.
  • Stand against UV rays.
  • Retain heat at night.
  • With enough rings, it can cover all of your pool, stopping evaporation as well as dirt. 


  • Lightweight, easy to be carried away by strong winds. 
  • Deflate quite quickly (about a week after inflation).

Complete Buying Guide: How to choose the best solar pool heater

best solar pool heater

The solar heating system is the most economical, eco-friendly, safe, and efficient for anyone who wants a warm pool. However, not all solar pool heaters are the same. No matter if you have basic knowledge or not, this topic will stress you out nonetheless with brands and choices as much as the number of species of flowers. 

That is the reason why I have this section right here. In this section, I will present many factors that make the best solar pool heater. However, my expectations and standards may be different from your opinion. Below are just suggestions, so don’t trust us blindly, but depend on the needs of your family and yourself.

Pool Type

best solar pool heater

Most solar pool heaters can work with any pool type, but they give out the best performance with some will. Some even go exclusive to a pool brand as a set. For example, if your pool is above ground, it needs less heating ability and requires a cover to prevent heat from going out of the water at night.

If it is an in-ground, it needs a larger panel to maximize sunlight absorption and a more powerful solar pool heater because the heat cycle gets faster. In such cases, panels are usually put on the roof or grass to get as much solar radiation as possible. 

Pool Size

best solar pool heater

The principle of a solar pool heater is pouring hot water into cold water and let them blend in. The heat from hot water and the cold from cold water will even out, leaving little change in temperature. Just like that, if there is too much water in your pool, it will take too much time to heat up, and no one likes to wait too long. Therefore, choosing a solar pool heater suitable for your pool size is necessary. 

If you have a small to medium pool, then a single small to medium solar pool heater is enough. If you choose the bigger size, there will be a significant amount of unnecessary heat. It is the same for large pools. You should use large panel solar pool heaters or use multiple stand-alone solar pool heaters connected. Usually, the pool should be for a solar pool heater written on the product package or the instruction.

Available Space

best solar pool heater

Before purchasing, consider the space you have for installation and for storing as well. Solar pool heaters come in different shapes and sizes: dome, panels, tubes, rings, etc. Also, even the best solar pool heater cannot give its best performance without a bit of space. Your solar pool heater could not work effectively if it got clamped up between many things else. It needs quite some space.

Easy Installation

best solar pool heater

This section will divide the solar pool heaters into two groups: those that need professional help and those that do not. In group 1, there is nothing you can do but stand by and wait for the system to be ready. This group may cost quite a lot more for professional help. But in group 2, with straightforward and easy to understand instruction, consumers can assemble, install, and set up the heating system all by themselves. The extra cost will be the cost of installation kits or spare parts. 

Some additional accessories

These features are not must-have on every solar pool heater, but it helps to operate them more quickly, and you can get the wanted outcome.

best solar pool heater

Programmable Timer

A timer lets you decide when you want your heater to start pumping warm water into the pool. This is especially beneficial in hot regions or on blazing days. If the pool water temperature gets too hot, it damages your skin, ruining your relaxation time. This device helps switch off the heater after an amount of time, not allowing it to disturb your happy time. Instead of a programmable timer, users can choose to buy a control kit with sensors and actuators. However, as it is much more technically modern and upgraded, the price goes up as well.

Temperature Control System

Once equipped, this temperature control system can show you the swimming pool’s current status and control the solar pool heater to adjust the water to your standard temperature. With two sensors and an automatic 3-way valve, it effectively controls the water flow and the pool temperature without a touch of your hand. All you need to do is set the desired temperature and have fun while the temperature control system does its mission. 

Roof Mount Kit

If you plan to put the panels or mats on the roof or rack, this product should be on your list. Some models may include the roof mount kit in your package, but this is not the case more than usual. However, most manufacturers produce roof mounting kits that go with their products, so you will not have a hard time looking for one that suits you. On purchasing the roof mount kit, you get brackets and straps to hold your solar panels in place for when it gets windy. 

best solar pool heater

Dedicated Pump

Most solar pool heaters can work seamlessly with existing standard pumps. Still, it does not mean everyone should use existing pumps only. Even if it is the best solar pool heater, it can create backpressure while using, affecting pumps’ function and preventing filtration. One more problem that may arise is that the solar heater cannot connect to the pump. That being said, a pump used only for this model of solar pool heater is the best solution. On top of that, dedicated pumps are usually sold at a relatively low price if that is what you are worrying about.

Bypass Kit

A bypass kit lowers the current speed through the heater and makes some or all water go away from the heater. Many people find this function useless and consider it a waste of money. This bypass kit is very much needed when you combine many solar pool heaters. Slowing down the current speed minimizes leaking and pressure between the joints, helping the product stay longer. Also, it helps lower the pressure of water on heaters and maximizes heat absorption. Who can say the bypass kit is useless now?

As I mentioned earlier, this is just our suggestion, based on our experience and in-depth research. You may find your best solar pool heater in none of my top picks due to differences in purpose and preference. Nevertheless, I hope you find this article informative.
