Buying Guide

With several models on the market nowadays, which are not necessarily the greatest out there, it is important to know what to look for before investing in one. Nonetheless, we have dedicated our time to provide you with the most efficient models because we strongly believe that you deserve only the best. So, before you jump right ahead, and purchase a unit, let’s take a closer look at what features you should keep in mind when choosing one:

  • State law and Regulations – Owning a pool heater that utilizes sun rays instead of electricity, is indeed a great way to save up money, as well as enjoy warmer pool water. However, sometimes owning one is forbidden, as it can be considered as an unlawful tamper with water supplies. Therefore, before you decide to purchase one, check the local regulations.
  • Space and Placing – Before you purchase one, ensure you have enough space to set it up. Where are you planning on setting it up? Can your roof support it? Does your yard have the necessary free space to allow a by-the-pool set up? Are you planning on using a rack? Once you’ve decided on the general placing area, consider the sun position and its direction. Note where the East and South are located in your yard, and put the panel where it can accumulate the most sun rays.
  • Size and Style – While several panels can work with either type of pools, above or in-ground, some function with only one type. Thus, according to style your pool has, you should pick one that will fit it. Additionally, another factor you should think about is the size of your pool, because with a large pool you’ll need more panels to keep the entire quantity of water present in it, heated up.
  • Pump Type – Almost all the solar heaters can be connected with the current pool pump you own. However, according to what model and what strength it has, you might find yourself in need of acquiring additional connections. For example, for pumps that have a strength that exceeds 1.5 HP, another kit will be required, to connect it with the panels.
  • Installation – Ranging from prototype to prototype, the installation will differ, since it can be a breeze, with the heater up and running in no more than 30 minutes, while others might be a bit trickier to set up, and will require some technical knowledge. So, depending on how much time you can afford to allocate to its installation, as well as your technical skills, several choices are available to pick from.
If you wish to maximize the sun power, you can also utilize a solar ionizer. This will also help you to keep the pool free of algae, as its sanitization function will aid chlorine in the fight against bacteria

All in all, if you will keep the aforementioned tips in mind before you decide on which model suits your needs best, then surely you’ll pick the best selection for your needs.


Frequently Asked Questions


? How does it function?
Usually, it uses an already functioning pump, most of the times, the same pump as the one you have in your pool, to transport the cold water through the filter, and into the heater itself. By spending time under direct sun rays, the panel will have already warmed up, and will circulate the cold water on its surface, heating it up as well, and returning it into the pool. Then, the process repeats itself.

? Where should I place it for increased efficiency?
Generally speaking, it should be placed where it has access to constant sun rays – on your roof. But this is not always the case, as it might happen that your house roof is constructed in such a way that doesn’t give it the ability to support it. So, in order to use the panels regardless if you place them on the roof or not, they tend to have versatile installation ways. Therefore, you can place them on a rack, directly on the ground, with some allowing you to even place them vertically, on a fence.

? Can I use it with a cover?
Sure! A cover will increase the efficiency, since it will not only prevent the water from evaporating during nighttime, but it will also trap the warmth inside the pool, preventing its escape. And, depending on its type, it can even provide increased safety for your household.
? How do I drain it?
There are 2 ways to do it – if your panel has gravity draining, it will be an automatic process, or, if it’s not equipped with the aforementioned system, you’ll have to do it manually. Close the pump valve, and wait for the water to drain completely. Keep the pipe-ends open during winter, and close them back in spring, when you re-start using the system.

?How many panels do I need for my pool?
It’s not a definite number, since it is highly dependent on multiple factors, like the pool size, its shape, its ground type (in or above ground), as well as its overall water capacity.

?With how many degrees will the water be warmer?
Sun intensity and weather, as well as the size of your pool, have a major role in determining how warm the water will get. Usually, they can heat from 5 degrees Fahrenheit up to 15 degrees Fahrenheit.
? Is it easy to operate?
Yes! The models nowadays are mostly automatic, letting the sun shine, and heating the pool without your supervision. Cost-friendly, as well as eco-friendly, you won’t see a rise in your annual electricity bills.



Final Thoughts

As long as the sun shines, with the help of a solar pool heater, you’ll have warm pool water. Therefore, you can easily prolong the swimming season, lengthening it till late autumn. So, depending on the type of pool you own, as well as how much free space you have, there are several choices to select from. Surely by now you’ve already picked your favorite, but if you’re still not sure which one suits you best, let’s quickly review them:
