This covers the water in the pool and absorbs heat from the sun. this is traditionally cheaper compared to the other types of solar heaters you will find in the market. If you decide to go for this, color is one of the most important considerations. Whether you choose transparent or opaque will have an impact on the absorption of energy from the sun and the heating capacity. This type of heater is also favored by many because it prevents the evaporation of water.
Solar Sun Rings
If you have a small pool, this can be a good choice. As the name implies, they are in the form of rings. The circular solar-powered heaters are left floating in the pool. You will need several units if you have a bigger pool. Like with solar blankets, this is also great in the prevention of evaporation.
This is easy to recognize from its construction. It has a clear plastic dome on the top. Inside the dome, there are coils.

Otherwise, you will need to combine several units. This is also a good option if you are looking for a compact and lightweight pool heater.
Essential Factors to Consider
To help you narrow down your choice and come up with an intelligent decision, this section talks about some of the most important considerations in your search for the best solar pool heater.
One of the first things you need to do is to consider the size of the solar heating system that you will need. If you have a large pool, you will need a large heater. If the heater is small, you can consider using several units to improve the heating capacity, but this will translate to additional expenses because you have to buy more.
The size of the solar heater will also depend on the size of the pool, collector efficiency, solar resource, climate, and average temperature that you want for the pool once it heats up.
It is also important to consider the amount of solar energy that is available from where you live. If there is an abundant solar resource, it is unlikely that you have to worry about it. The problem enters the picture when you do not get enough sun from where you live. This will make it harder to the solar pool heaters to do their job, so you have to consider those that are more efficient.
Type of Pool
Aside from the size of the solar pool heater, it is also important that you consider the type of the swimming pool where you will use it. For instance, whether you have an in-ground or above ground pool will dictate what product is the better option for you. Especially in the case of small solar pool heaters, they are designed only for above ground pools. In-ground pools are traditionally larger, so you have to choose a more powerful heater.
Type of Solar Collector
This is one of the most important parts of the solar pool heater as this dictates the ability of the unit to absorb and trap heat. Unglazed collectors are made of plastic or rubber. Glazed collectors, on the other hand, are made of copper tubing with aluminum plate. Glazed collectors are more expensive but also more durable.
The easiest way to determine the durability of the solar pool heater is to look at the materials it uses. It should be made using premium materials that can withstand the time, which is also why you should not hesitate to spend more if this means that you will enjoy longevity. The good thing about solar pool heaters is that most of them can withstand years of use.
One of the best things about solar pool heaters is that they do not require professional installation. With this, you can assemble the unit on its own. However, this can be frustrating, so consider how easy it is to get the heater ready before you can finally use it. Read reviews from other users and learn from their real-life experiences.
The standard warranty that is offered by most manufacturers is one-year. If possible, choose a product that comes with a longer warranty coverage. This way, you can have peace of mind as this is also proof of how much the manufacturer believes in the quality of their product.
Tips When Using Solar Pool Heaters
Before we end this brief buying guide, allow us to leave you with tips on how to make the most out of your solar pool heaters:
- Install the heater at the right position. The most important is for it to trap the heat of the sun, so it should be positioned somewhere it can directly absorb the sun’s energy. For versatility, it is also good to choose a heater that is easy to change the position.

- Trim trees around the pool area if you want the water to be warmer. This is one of the easiest solutions to prevent the water from being cold in addition to the work of the solar pool heater. Plus, when you get rid of the shade, the rays of the sun will easily reach the solar heater.
- Install solar heaters in areas that are hard to reach either of humans or animals. This way, you are minimizing the possible damages.
- Improve the chemical balance of the pool. For instance, you might want to consider adding more chlorine, especially now that you will be using the swimming pool more frequently since the water is warm and comfortable.
- If you live in a place where it is extremely cold or when it is the peak of winter, solar pool heaters may not be sufficient. It is best to use gas or electric heaters instead since they are more powerful. Besides, the sun may be quite shy from where you live, and hence, there will be lack of heat that the solar heater can absorb and use for warming your pool.

Gone were the days when you despise a dip in the pool once the temperature starts to drop. With this type of heater, you can make the most out of your swimming pool at home and have a lot of fun.
