How to Choose a Solar Pool Heater
There are a multitude of factors you should take into consideration to ensure you get the most out of your setup. These could include how large your pool is, how much you’re willing to spend, or how much sunlight you normally get. Luckily there are some general guidelines you can follow that can make your selection and buying process much smoother.
Most of the above mentioned solar panel heaters have their unique advantages and disadvantages. Still, overall they will get the job done without much worry or effort on your end. Any panel you choose will be a noticeable improvement over not having one at all, so here is a guide to selecting the panel that will give you the best bang for your buck.
Does it Get the Job Done?
How do these panels even work? Solar heaters have three main components, a filter, a panel, and a pump. With these three components and a dose of sunlight shining into a panel, a cycle begins that produces heat for water in a pool to utilize.
The process begins when a solar panel heater pumps water from a swimming pool into a filter. The filter will clear the water of any debris and impurities, and then direct the water into the panel. As the panel absorbs sunlight, it heats up, and the water traveling through the panel gets heated up as well. As the newly warmed water is pumped back into the pool, the entire swimming area is now much warmer.
The panels are the critical factor here as they determine how quickly and efficiently water is heated up and relayed back to the pool. Smaller pools will get away with smaller pool heaters, but for larger and deeper pools, you will require more panels and larger systems.
Depending on whether your pool is above ground or inground, that might determine which system you go for, as some only work for designated types. For example, the above mentioned Fafco Solar Cub Environmentally Friendly Above Ground Swimming Pool Solar Powered Heating System is for above ground pools compatibility. Making sure that your pool is the right kind for the heater you want to get will prevent you from buying the wrong kind.
There are two main builds for solar pool heaters, glazed collectors and unglazed collectors. Glazed collectors are built from rubber or plastic and are typically more expensive than unglazed, which are on aluminum plates with tempered glass coatings. For the increased cost, you typically get more durable systems with glazed collectors.
What Size Do You Need
To calculate the right size of the system, you’ll need, check the surface area of your yard. Your solar system should be around 75% of the surface area of your yard, and that number increases the longer you want to keep your pool open. Up to 100% if you want to go all year round. For example, the average size of a swimming pool in the United States is 14×28 feet. For 100% surface area, 14 multiplied by 28 equals 392 square feet. Meaning your solar collector will need to be 392 square feet if you want a pool of that size to run year-round, and you’ll have to get a system with that surface area in mind.
What Are The Advantages?
Solar pool heaters have huge advantages when compared to other systems like gas or heat pumps. For one, they are extremely eco friendly and don’t waste any energy. Maintenance costs are nonfactors since solar panels require almost nothing to keep functioning. They will work efficiently for years, if not decades, after installation and are immune to factors like power outs. If panels are damaged, they can usually be replaced easily, most of the time, without having to replace the entire system.
Another advantage is that you can place them in a variety of convenient and out of the way locations. You can set them on your rooftop and forget all about them while they do their jobs without you having to worry about anything else. On top of that, they can make any area look a whole lot sleeker too.
Installing your solar heating system can be a constructive DIY project, though most brands provide an expert installation that will take care of everything on your behalf. Tons of factors like roof height, panel size, pool size, and efficiency are all taken into account by professionals when they set up your system, and some of those might be easy to miss if you try yourself.
It’s also safer when it comes to warranty eligibility. In the case that something gets damaged during installation going with a professional can resolve the problem without you having to pay extra. Liability during a complex set up can be a significant reason to go with the proper help. However, if you’re sure you know the ins and outs of solar panel installation, setting up your solar heating system can be something that you can do yourself.
After installing the solar panel, To connect it to the pool, the process differs depending on if you have an above-ground or in-ground pool. Generally, though, for the most part, you’ll need to disconnect the main hose in your pool and plumb it to the solar heater. Following that, add another hose from the heater to the return fitting on your pool. We recommend having experience in plumbing and DIY, but typically instructions are well detailed and laid out.
What Else You’ll Need
There are plenty of other items and accessories you can buy to ensure your panels are running as efficiently as they can be. For some systems, you can utilize a liquid heat shield. A bottle of this in your pool will help prevent water evaporation from keeping your pool warm. Another accessory is a reel system so you can apply, move, and fold up a solar blanket with ease.
These reels have cranks that you can use to adjust your distance manually. We recommend you invest in a solar cover for your system. These covers prevent heat from spilling out, making sure everything goes to your pool directly. To prevent leaks and damage, it’s usually wise to keep some Teflon tape and silicone sealant on hand to quickly patch up any holes. Accessories like these will make the adjustment and usability of your solar pool heaters far easier.
Frequently Asked Questions About Solar Pool Heaters
How much will a solar pool heater cost?
