9 Best Solar Pool Heaters 2024
Solar pool heaters are one of the most efficient and cost-effective ways to heat your pool whether you have an in-ground pool or an above-ground pool. Solar pool heaters require minimal maintenance and can extend your swimming season by several weeks or even months.
Swimming is a great way to exercise and have fun, but the cost of heating your pool can be expensive. Solar pool heaters are a great way to save money and keep your pool at the perfect temperature.
In this article we look into the ins and outs of the best solar pool heaters to heat up your pool for both in-ground and above-ground pools.
How does a Solar Pool Heater work?
Have you ever wondered how a solar pool heater works? It’s a fascinating process that utilizes the power of the sun to raise the temperature of your pool. The system consists of four main components: the solar collector, filter, pump, and flow control valve.
- Solar collector is the heart of the system. It is a series of tubes or panels that are installed on your roof or in your yard. These collectors absorb sunlight and transfer heat to water or a special solution running through them. The heated water then flows back into your pool, to raise your pools temperature by several degrees.
- A Filter is responsible for cleaning debris and other contaminants from the water before it reaches the solar collector. This ensures that only clean water enters the collector and prevents any damage to it.
- The pump circulates the water between the pool, filter, and solar collector while maintaining proper pressure levels.
- The flow control valve regulates how much hot water is returned to your pool at any given time, ensuring that the temperature stays consistent throughout. By doing this, you can enjoy perfect swimming conditions regardless of whether it’s warm or not outside.
Solar panels are laid on a roof, a rack, a fence or on the ground and pipes are installed from the solar panels to the pool pump.
The pools pump pushes the water from the pool through the solar panels many tubes to the solar collector where it is heated by the sun and returns to the pool through the exiting jets.
The amount of heating that takes place depends on how much sun is available.
During the process, the pool gains heat slowly, the water in the pool stores heat overnight, so solar panels only need to recover the lost heat until the next day where the heating process repeats itself, weather permitting.
Using a solar pool cover, during the day and at night will improve the amount of heat retained.
Benefits of a Solar Pool Heater
A solar pool heater is a great way to extend your swimming season and enjoy all the benefits that come with it, without breaking the bank. Here are three reasons why you should consider investing in a solar pool heater:
1. Cost-effective and eco-friendly: Solar pool heaters are one of the most cost-effective ways to heat your pool, since they rely on free energy from the sun. They’re also much more environmentally-friendly than gas or electric heaters, since they do not release any harmful emissions into the air.
2. Extend your swimming season: With a solar pool heater, you can extend your pool season and enjoy swimming for weeks or even months longer than you would be able to without one. There’s nothing better than taking a dip in your own private oasis on a warm summer night.
3. Low Maintenance: Solar pool heaters are very low maintenance. Unlike gas or electric heaters, there are no moving parts that can break down over time. All you need to do is make sure that the panels are kept clean and free of debris, and you’re good to go.
Different Pool Types
Swimming pools are a popular addition to many homes, and there are two main types of swimming pools available: above-ground pools and in-ground pools.
Above-ground pools are typically less expensive and easier to install, while in-ground pools offer more design options and a more permanent fixture.
When it comes to solar heating system, the type of pool you have can impact the type of heater that is best suited for your needs.
Above-Ground Pool
For above-ground pools, a solar blanket or solar mat heater is often the most popular option. These types of solar heaters are affordable, easy to install, and can increase the temperature of the pool water by a few degrees.
Solar blankets are made of a durable, UV-resistant material and float on top of the water to trap in heat from the sun. Solar mats are placed on the ground beside the pool and use a series of tubes to absorb the sun’s energy and heat the pool water as it flows through them.
These types of pool solar heaters are ideal for above ground pools because they are cost-effective and easy to use, making them a great choice for those who are new to pool ownership or pool owners on a budget.
In-Ground Pool
In-ground pools, on the other hand, may require a more sophisticated pool solar heater to meet the heating demands of a larger pool.
A popular option for inground swimming pools is a solar panel system, which consists of a series of panels that are installed on the roof of the house or on a separate structure near the pool.
These solar panels are designed to absorb the sun’s energy and transfer it to the pool water, increasing the temperature by several degrees.
Solar panel systems are ideal for inground swimming pools because they are efficient, reliable, and can be customized to meet the needs of larger pools. While they may be more expensive than other types of solar pool heaters, they offer a great return on investment in the form of lower energy bills and a longer lifespan compared to other types of heaters.
For both pool types, there are solar pool heaters to suit.

How Many Solar Panels Are Needed To Heat A Swimming Pool?
The number of solar panels required to heat a swimming pool will depend on several factors, such as the surface area of the pool, not the volume as heat loss occurs through evaporation at the surface, the desired temperature, the amount of sunlight your location receives, and the efficiency of the solar panels.
Solar panels come in many different sizes and how long you want to keep swimming for as the temperatures drop, so it is difficult to estimate the number of panels required.
The table below gives an idea based on two typical supplier panel sizes that they offer and the number of months you may want to use the pool for.
Calculation of the estimated number of panels required is made by surface are sqft multiplied by the offset value of 50% for 3-4 months, 70% for 4-6 months, or 90% for 9-10 months, divided by the sqft of a solar panel, i.e. 4ftx20ft solar panel is 80sqft.
To explain offset, solar pool heating systems are calculated to cover between 50% to 100% of a swimming pool’s total surface area. For example, if you have a “50% offset,” it means that the combined surface area of all your solar panels matches 50% of your pool’s surface area.
The offset percentages above are not the rule, just an estimate and that the data in the table is provided as an example only, the actual number of solar panels needed to heat a pool will depend on a variety of factors, including location, climate, and desired water temperature.
It is always best to consult with a professional installer to determine the appropriate size of a solar pool heating system for your specific needs.
