One of the reasons why some people prefer swimming in a pool as opposed to ocean water is because swimming pools have more reliable and predictable temperature levels. However, with the cost of living going up, it’s becoming increasingly important to save on energy expenses and having the best solar pool heater is often the first thing to go for.

The good news is that it doesn’t have to be that way. Nowadays, we have access to effective and eco-friendly solar pool heaters that will keep your pool water feeling pleasant all year round without burning a hole in your pocket with high energy bills.

Plus, we’ve gone the extra mile to put together a truly comprehensive guide with all the information you’ll need to find your ideal solar pool heater.

How Does a Solar Pool Heater Work?

Solar pool heaters are undoubtedly the most inexpensive pool heating mechanisms available out there, and they work just as well as any other heat pump. The only difference is that your solar pool heater will only work at full capacity when it’s hot out, otherwise its efficiency will significantly diminish when it’s overcast.

What to Consider Before Buying the Best Solar Pool Heater

As with any purchase, it’s important to make a few key considerations when you start shopping for a solar pool heater. Luckily for you, we’ve covered most of these in the list below to help you choose the best option for your needs.

  • Size of the Pool

Your pool size matters a great deal when you’re looking for a solar pool heater because it plays a huge role in how the heater operates. Basically, small to medium-sized pool heaters are more suited to small-sized pools while larger pools require a more powerful system, especially if they have a lot of depth.

  • Build Quality

The type of materials used in constructing the pool heater will also have an effect on its longevity and ability to do its job (which is to heat your pool). If you’re looking for a durable model that will last long then you should definitely consider purchasing one with a glass coating, which is a quality that you won’t find in other heaters.

  • Pool Functionality

It’s important to keep in mind the specific function of your pool as well when purchasing a solar pool heater. For example, some swimming pools are used for recreational purposes and typically do well with a solar pool heater that can deliver the right temperatures for this purpose. Other swimming pools are for sports and exercise, and will thus require a heater that provides reliable temperatures.

  • Solar Pool Heater Cost

Of course, you must also consider your budget and make sure that the pool heater you purchase is priced just right while offering good value for money.  You also have to keep in mind that you will get what you pay for since pricey solar heaters are usually the most effective, but you can still get good quality systems within a reasonable price range.
