5 Best Solar Pool Heaters Of 2024

Last Updated on June 21, 2024

Nowadays, we have access to effective and eco-friendly solar pool heaters that will keep your pool water feeling pleasant, not just during swimming season, but all year round without the heating costs burning a hole in your pocket with high energy bills.

We all love to take a dip in the pool to unwind and relax, but it can be hard to find enough time during the day to enjoy your pool when you’re working. Luckily, solar heaters were invented to heat your pool water so that you can swim any time of the day or night!

What Are Solar Pool Heaters?

A solar pool heater is a device that heats your swimming pool using the sun’s rays. It does this by absorbing heat from the sun and transferring it to your water through a process called convection. This means it doesn’t need any electricity or gas to do its job but will typically use some form of power for circulation with the help of your existing pool pump.

The pool water passes through your solar heating system and it goes back to your swimming pool warm.

What to Consider When Choosing A Solar Pool Heater

As pool owners, it’s important to be mindful of the energy costs associated with running your pool all summer long. One way you can save money and reduce your impact on the environment is by choosing a solar pool heater. There are many different types available in stores today but before you make a decision, consider these factors:

Pool Size

Every pool owner has a different heating system for their pool and it’s important to know what size your pool is before ordering a heater. One of the most common mistakes that people make when they buy a new heater is not considering the size of their pool or how long it takes to heat up, which can lead them to spend unnecessary money on an inefficient system.


Pool owners should consider the location of their pool since this can have a huge impact on how much energy it takes to heat it. The best location for solar pool heating systems is a south-facing roof or flat area as they provide the most sun exposure during the day. North-oriented racks should not be considered, but west or east orientation is preferred in the northern hemisphere.

When installing a solar pool heating system it is important to determine what location will work well with your house and the type of installation you desire (roof-mounted vs ground-mounted). The efficiency of this kind of system depends on how much sunlight can be collected during different times throughout each day so choosing an appropriate location is crucial!

Pool Pump

The speed at which the water circulates through the panels must not exceed what these solar-powered devices are designed for. Solar pool heaters will not work properly if the water flows too fast through them. The heat from the sun won’t have enough time to be absorbed by your pool water and you’ll end up with an unheated swimming area.

Let’s consider a solar pool heater that is 2 feet by 10 feet as an example, this solar panel works well at 1.5 gallons per minute. If you have a 30-panel solar heating setup, you only need your pool pump to bring about 45 gallons per minute for the system to work at its best.

How Many Solar Panels Do I Need For My Pool?

Homeowners should always consider a solar collector that is the full size of their pool, or larger if they want to keep it open throughout the year.

You can increase this number depending on how warm you prefer your water to be and how many months out of a whole year you plan to use your swimming pool.

For example, if a pool is 20 feet wide and 30 feet long, it has 600 square feet of surface area. Therefore, the total surface area covered by your solar panels should be at least 600 square feet.

For those living in warmer regions, you can go by with just 50% to 80% of your pool’s total surface area for your solar collector.

Pro Tip: To make your solar heating system more efficient, you should use black PVC pipes and fittings for your plumbing system.

Believe it or not, the number one question I get from pool owners is what kind of solar heaters are best for their pools. With so many types and brands on the market, choosing among the available options becomes such a daunting task.
