Advantages of Using a Solar Pool Heater
A solar pool heater comes with many benefits for the user.
i) No Waiting for the Right Season of the Year
If you have a swimming pool at home, you want it to be functional all year round. A solar pool heater allows you to warm up the pool no matter what the temperature is. Thus, allowing you to make the most of it.
Solar pool heaters are environment friendly as they use the sun’s energy to generate heat. It is perhaps the eco-friendliest way to heat your pool without any carbon footing. Since it uses no gas or fuel, it releases no harmful emissions into the air either.
If you want to take it a step further, investing in a solar blanket is a good idea. It helps the water keep the warm temperature even at night.
Using a solar pool heater helps you save much money as you rely on the sun’s energy instead of paying for additional electricity bills in the case of electric heaters. Your only money spending is in the beginning, and after that, it is just occasional maintenance.
On the average solar pool, heaters can go up to 15 to 20 years. However, some of the more high-end brands can also go up to 30 years. Thus, it is not only a one-time investment but also a long-lasting one.
v) Low Noise
Despite what it may look like, solar pool heaters are noiseless. They do not create any humming noises either so that you enjoy a nice soundless swim.
Since solar pool heaters do not come with electrical wiring or components, there is no chance of water damaging them.

Things To Consider Before Choosing the Solar Pool Heater
It would be best if you kept in mind the following factors before picking out a solar pool heater that suits you best. Installing a solar was never so easy by getting heat from the sun.
However, now pool owners can get different types of solar for the ground swimming pool. A solar system pumps the pool water after installing a solar. You also get the direct flow system of warm water per day for your swimming pool using solar energy.
Since the heating efficiency and the collection of heat is dependent on how much sun it receives, the location matters a lot. If you live in a sunny area like Florida, then a solar pool heater is a great option.
However, for people living in colder climates, you must get a pool heater with high output and heating.
This is important for a pool solar or ground pool.
iii) Pool Size and Type
Naturally, the larger the pool, the greater heat it will require, and so the solar panel or collector should be equally large. It should be able to cover at least 80% of the size of the pool.
Another consideration to keep in mind is the pool type. As discussed above, some solar pool heaters are made for in-ground or above-ground pools only. Some are compatible with both, but you need to be sure of it.
Moreover, temperatures in the water vary for leisure and exercise pools, which should also be kept in mind.
iv) Roof Stability
Since most solar panels are placed on the roofs of houses, the roof should be reliable and sturdy. This is so because it should be able to hold it for several years. Thus, if you think your roof is not strong enough, you should arrange it beforehand.
In some cases, a simple solar panel or mat is not sufficient to heat the pool. Sometimes you need additional accessories to enhance the performance. Although the other accessories are not a must, we still recommend them to maintain it better.
vi) Mounting Type
Solar pools have three kinds of mounting options: flat, racking, and rooftop. Flat mounting is mostly applicable for solar heat mats, which simply need to be rolled out or spread flat on the ground.
These are not ideal though because it is better to have them placed at an angle for maximum heat collection. Racking systems are not as simple as mounting flat systems.
They mount at a tilted angle to achieve greater efficiency. Lastly, the rooftop mounting has the most extended Installation but is the best one in terms of space and heat collection.
Different Types of Solar Pool Heaters?
All solar pool heaters have the same function of heating the pool using the sun’s energy. However, there can still be differences in the way they operate.
i) Evacuated Tube Collectors
This is perhaps the most effective way to heat your pool, even though it is costlier than solar collectors are. However, they are more reliable and suit better to colder climates. It uses a system where smaller glass tubes fit into larger ones to create a vacuum.
When the sunlight heats the glass, the heat stays within the vacuum, then transfers with a heat exchanger to the adjacent water box. Thus the water heats until it goes back into the pool but at a higher temperature than before.
ii) Thermal Solar Absorbers
These are perhaps the most popular solar pool heater type. We place the solar panels on top of the roof or next to the pool. The thermal absorbers are either glazed or non-glazed.
The latter is of rubber mostly and the water transfers with a group of pipes. These are better for warmer regions. Glazed ones are more sturdy than aluminum, copper, or glass; these are better for colder regions.
Thermal absorbers are easy to install and also reasonably priced compared to other kinds of pool heaters.
Solar decks are easy to set up, does not require maintenance, are small enough not to spoil your house’s aesthetic but rather enhances it, and most of them come with rechargeable batteries so that you never run out of light during the night.

It has 12 deck lights in a single pack, can be easily installed, and can work for as long as 12 hours a day!
Furthermore, it has a sturdy construction which further makes it one of our favorites. Our next choice is not because it is the best budget option but also because it has a pressure resistivity of up to 20 tons!
This means it can be used on the decks, driveways, and pathways without worrying they’ll get damaged by the weight of your feet, cars, and trucks. Furthermore, it has Ip68 waterproofing, which means it can survive all types of problems.
If you haven’t found the perfect solar deck lights till now, then go over the above ten enlisted ones. They have a long shelf life, can withstand harsh temperatures, and helps conserve energy.
Ideally, you should opt for the rooftop mounting if the Installation is not too expensive. The next option should be racking system one as it is at an angle that maximizes heat radiation.
