How To Choose The Best Solar Pool Heater

There are many things to consider before buying a solar-powered heater so that you can get the finest solar pool heater for your requirements.

Pool Size

Because heaters are designed for particular pool sizes, the most essential thing to consider when buying your pool heater is the size of your pool. Some heaters are better suited to big pools, while others are better suited to small pools.

Type of Pool

Although no two pools are alike, there are many distinct kinds of solar-powered pool heaters. If you possess an inground pool, for example, you must make sure the solar pool heater you purchase is intended for that kind of pool, or at the very least for several pool types, such as your inground pool. If you’re purchasing a multifunctional solar pool heater, be sure the installation package contains the necessary instructions and components for your pool.


Solar pool heaters are designed to conserve you money on energy or gas costs, but they don’t have to be expensive. Stick to your budget and avoid overspending on solar pool heaters with unnecessary additional components or features. Also, bear in mind that hiring an expert to build your heater may cost extra. If you’re on a tight budget, look for pool warmers that you can install yourself, such as those in our list of the best solar pool heaters.


Pay close attention to your new heater’s power rating. The power rating dictates the kind of pump and pool size that it can handle.

Easy To Setup

If you’re going to do it yourself, be certain your solar pool heater is simple to set up. Many of the heaters on our top solar pool heaters list may be installed without any technical knowledge. Purchasing a heater with a simple user manual will save you a lot of time and work.

Pool Temperature Preferences

Not all solar pool heaters provide the same level of warmth. Some are much more productive than others, making them more suited to certain climates. You don’t need a highly strong solar heating system if you reside in an area where your pool just requires a little warmth. If you live in a colder area, however, you should invest in a solar heating system that can quickly increase your water temperature by at least 10°F.

Frequently Asked Questions

1. How Many BTU Pool Heater Will You Need?

Now let’s check at how big of a pool heater you’ll need for a particular location. As I previously said, you can’t truly forecast solar energy without costly meteorological gear that can provide you solar output over time and create patterns that you can translate into thermal units.

If you’re planning to utilize a surface sheet heating system, make sure you have the same quantity of material as the water’s surface area. If you have an above-ground pool, you may wish to use this material to line the pool’s sides as well.

Examine the quantity of water that tends to flow through exchange heaters in a given period of time. You want it to pump at least a third of the water in your pool through it each day, if not more.

Indeed, the water will be a little warmer than you would like the pool to be, but the dilution and exchange with the colder water will result in a pool that is more evenly heated.

2. Is It Necessary To Maintain Solar Pool Heater?

Barely. The majority of solar pool heaters are designed to last at least 5 years with little maintenance or repairs. Most of those heaters on our list come with 10-year warranties that bear the expenses of repairs or replacements if they are damaged. You should have no issues as long as your setup is completed correctly.

3. What Is The Lifespan Of A Solar Pool Heater?

Solar pool heaters that are well-made may last up to 20 years. However, how effectively it is installed determines how long it will serve you, so hiring a professional to build your solar pool heater is a good option if you aren’t skilled.

Solar pool heaters can be mounted on the roof, yes. Solar pool heaters may be placed anyplace that gets enough sunshine and is close enough to the pool. Roofs of houses, garages, and sheds are popular installation locations.

6. Can A Solar Pool Heater Work At Night?

The easiest approach to get the most out of your solar pool heater is to place it in direct sunlight. Warm days with a light to medium overcast are also acceptable. Operating a solar heater at night or on cloudy, rainy days will not enable the device to heat the water enough. In certain instances, it may even lower the pool’s temperature.

7. Is It Possible To Use A Solar Pool Heater In The Winter?

It relies on where you live whether or not you can use a solar pool warmer in the winter. A solar pool heater can work during the winter in areas with year-round sun and warmth.

In colder regions, these solar pool warmers may prolong the swimming season by a few weeks, but they should not be used in the winter. If a solar pool heater is operated outside of its specified working ambient temperature, it may be damaged by freezing temperatures.


If you’re thinking of installing a solar pool heater for your pool, you should do your homework beforehand. Many individuals are unaware of how they operate or what is required to properly install one, so we hope that our purchasing guide has been useful.

Solar heating may help you save money on your gas or electric bills, but you must get your setup properly to get the advantages.
