Why Should You Invest in a Solar Powered Pool Heater?

If you’ve scrolled this far, you’re definitely considering investing in a solar-powered pool heater. However, you might still need a little nudge towards it. With gas and electric pool heaters offering complex designs with air pumps or higher temperatures, they might seem much more inviting for your pool. However, stick with us just for a few minutes more, and we will tell you why investing in a solar-powered pool heater is the best decision for you.

1. Cost-Effective 

The number one feature a good product can have is an inexpensive package. With a gas pool heater, the installation might be cheap; however, the maintenance of these types of heaters will end up skyrocketing your monthly gas and electric bills. When you buy a solar-powered pool heater, though, your only cost is the initial buy as it will then require no further bills to keep functioning. To add to that, the cost of most solar-powered pool heaters is already on the lower-end.

2. Low Maintenance

With no wiring or multiple parts involved, you will not have to constantly worry about the upkeep of owning a pool heater. Most solar heaters come with flexible panels or a portable structure, which should make the storage easy. There is next to no maintenance involved as once you set it up, you will not need to constantly keep readjusting the parts.

3. High-functioning

While electric and gas heaters may deliver a good performance at a high price, with solar-powered pool heaters you get high-functioning panels that are just as effective if not more. Using nothing but the solar rays to warm up your pool, these panels are designed to catch all the sunlight that falls upon it. Some solar pool heaters are able to provide a temperature boost by upto 15°F, which should be more than enough to provide you with a comfortable swimming environment.

4. Eco-friendly

The best part of owning a solar-powered pool heater is definitely the environmental benefits. You utilize only natural energy to warm up your pool and leave no negative consequences to the environment. This mutual benefit system is far better than any electric or gas-powered pool heater that, in turn, can use up resources and cause more damage to the environment.

Features to Look for While Purchasing Solar-Powered Pool Heaters

So you have browsed through the list and decided to go for the eco-friendly route and buy yourself an effective solar-powered pool heater? Before you excitedly pick one, though, go through the following list of features to look for when buying a solar-powered pool heater. This is to ensure that you get a product that will be perfectly suited for you and your pool.

Size of the Panels

The first thing to consider is the panel size. The wider the surface area, the more exposure the panels can get and thus gather sufficient heat to warm up your pool. This does not, however, mean that you should simply purchase the largest panels in the market as it will also matter whether you have enough area for it to be spread upon. Some solar pool heaters follow a different design all together by sporting a more compact design. In this case, you should make sure that it is able to converge the light that falls on it, to effectively heat the water that flows through its tubing.

Versatility

While you may already know what kind of pool you will be purchasing, it is better to go for one that can still offer a degree of versatility. This will make sure that it is not limited in its usage. Along with this, you should look for one that can offer easy storage. Some solar-powered pool heaters come with flexible, foldable panels that can be moved easily but also spread out to cover more ground when required.

Price

When it comes to solar pool heaters, it is likely that you will get what you pay for. Usually, this does not mean that the cheaper heaters are not effective, but can be prone to damage or leaks. These can be solved with a quick trip to the hardware store, but if you are someone who wants to avoid this hassle, definitely invest in a higher-end product.

Durability

Finally, it will always come down to the quality of the materials used. The panels will need to be UV resistant so that it does not erode quickly. You will need to check that the product is not susceptible to easy rusting as it will frequently be around water. Make sure the materials for the panels as well as the parts are durable and designed with long-term functionality in mind.

FAQs on the Best Solar Powered Pool Heaters of 2020

A typical solar pool heating system works by pumping the water through a series of tubes while the panels work on gathering heat. The water is heated as it passes through the tubing, and then either through direct flow or other pipes, the water is let back into the pool.

While heating efficiency nearly always depends on the pool size, on average, a solar pool heater can get the pool temperature as high as 78° F to 85° F. This will work much better if you pair it with a swimming pool cover to retain the heat.

Solar pool heaters have a 90% efficiency. This value will fluctuate based on factors like available daylight or pool size, but if it’s a sunny day and you’ve got a good quality solar pool heater, then they will definitely work.

The size of your pool is a big factor in determining how effective the heating is. The rule of thumb is that you should have solar panels that are at least half the total size of your pool. For above-ground pools, even smaller solar pool heaters should be able to deliver warm water for a pool of 18 ft.

Generally, panels made from crystalline material last for a good 20-25 years. The film panels that are thinner usually have a life of about 2-5 years. The photovoltaic solar panels that are common in the market, however, also last for 25 years.

Wrapping Up,

With solar-powered pool heaters, you can extend the swimming season well into winter. This is not just a great decision for your pool but also for the environment. We hope the list and the buying guide above is able to help you make an informed decision on which solar pool heater is best suited for you.
