Irrespective of where you install them, there are a few guidelines you need to keep in mind. They work optimally with oval pools measuring 24 feet in length by 12 feet in width.

Criteria for Choosing the Best Solar Pool Heaters
Size of the Pool
Pools come in different sizes and shapes. Compared to smaller pools, bigger and deeper pools will need some significant heat to raise the temperature to comfortable and warm levels. As a result, you may need to invest in several, powerful heaters to achieve the same performance as a small pool paired with one, standard sized heater. And for particularly big pools, you may need to look into the possibility of buying a large and semi-permanent heater. On the other hand, if the pool is small, a small and portable option will suffice.
Ease of Installation
The vast majority of pools are either above-ground or in-ground installations. You need to keep this point in mind when shopping around for a heater as it can be the difference between effortless and quick installation and a time-consuming, energy-draining experience. The mounting location will depend on the type of installation you go for. Also, depending on the number of solar panels you decide to join together, the installation process can either be easy or quite complex. If you’re not technically savvy, it will be necessary to seek the services of a professional installer to ensure everything works as advertised or intended. It’ll incur you more money, but in the end, you’ll have a solar pool system that works like a charm, enabling you and your loved one extend the swimming season by several months.
High-end solar heaters cost a considerable amount of money, and it would be a waste if they were to stop working after just a few weeks. One safe way of guarding your investment is getting a heater with a considerably long warranty. In the event the system stops working as a result of the manufacturer’s use of defective or poor quality materials or a shoddy manufacturing process, the manufacturer will incur the cost of repair or replacement of the part. The warranty also gives you the confidence and peace of mind you need to work without any worries.
Ease of Use
A heater should be enough in design to make using it a cinch. The delivery package needs to have all the accessories you need to make all the connections without a hassle. Like we mentioned above, though, if the installation is complex, it would be prudent to get a professional to get it done quickly and properly, so you don’t run the risk of voiding your warranty by damaging anything. While on the topic of ease of use, consider the weight issue. Most options are bulky as they seek to maximum exposure to the sun. If it’s too large, it will definitely be problematic lugging it to and from the poolside, unless you have it installed semi-permanently or permanently on the roof. The heater should also be lightweight and compact enough that manoeuvring it around the pool is not a problem. Neither should be servicing when the time comes.
Harnessing the heat from the sun to heat up the swimming pool is a rigorous activity. If you settle for a cheap, off-brand unit from the market, chances are high it will wear and tear quickly. What you need is a heavy-duty heater made from industrial-grade and high-quality materials that are capable of withstanding the task. Similarly, it needs to be resistant to UV rays of the sun. Additional qualities are resistance to rust and corrosion given their constant exposure to water that may at times have a high chlorine concentration.
Frequently Asked Questions
Q: Is it necessary that I install my solar heater in a particular direction?
A: It’s not a mandatory requirement that your heater faces any one direction. However, irrespective of where the heaters are facing, ensure the direction aids in the optimal performance of the heater. There should be no objects or distractors in the direct path of the sun. Nevertheless, if your solar is not heavy or bulky, you can try facing it southwards at a 30-degree angle.
Q: Do heaters have any advantages over their gas-powered and electric counterparts?
A: Aside from performance, solar heaters have a multitude of benefits over their gas-powered and electric counterparts. For one, they are a lot cheaper and much easier to use. The installation process is a breeze and doesn’t require the involvement of a professional, at least for most of them. Also, they are eco-friendly and very economical to run and maintain.
