Pools are a great way to cool down in summer; however, owning a pool isn’t as simple as it seems. In fact, pool owners often spend a small fortune on keeping the water suitable for swimmers throughout the whole year and maintain the pool open as long as they need/want. Knowing the high costs associated with heating up pools, solar pool heaters are becoming increasingly popular. This renewable energy source enables warm pool water throughout the whole year and reduces the overall costs of water heating when relying on other heating sources like electricity or gas.
With this in mind, if you’re a pool owner and wonder if you should order a solar heater today, stay tuned! We’ll share important information and present you with the top 18 solar pool heaters for this year that you mustn’t miss out on!
Why Do You Need a Solar Pool Heater?
Solar pool heaters are systems that heat up pool water via the sun’s rays. Usually, these systems have four main elements, that is, the collector which moves the water, the filter which cleans the dirt as the water in the pool circulates, the manual or automatic valve for control of the flow of the water, and the pump which ensures the movement of water going from the pool to the collector and from the collector to the pool. The heater warms up the water by pumping it through the filter and flowing it through the tubes that transmit the heat from the collectors to the pool. Some solar heaters may also have automated sensors and valves for control of the flow. These elements help detect the temperature of the water from the collectors and ensure optimal pool water temperature (higher or lower). Namely, let’s say it’s sunny outside and the water in the pool is cool. The valve for flow control will redirect the water through the collectors and the heating panels will warm it up before it goes back into the pool. On the other hand, if the pool water is very hot, the valves will make sure that the extra hot water doesn’t enter the pool and cause the water to become even hotter.
One of the major reasons why pool owners decide to invest in a solar pool heater is to warm up the water in colder months.But, there’s another, less known benefit, that people living in very hot climates will certainly appreciate: the heater will ensure the water stays cool and comfortable by moving it throughout the night.
Still not sure if a solar pool heater is what you need? Check out other great advantages when you decide to invest in this heating system:
🌱 Longer pool season that lasts up to 5 and 6 months
🌱 Warm and cozy pool water temperature and undisturbed enjoyment for swimmers without the need for oil or gas
🌱 Saves you money in the long run because you won’t need gas or electricity to heat up the water
🌱 This system is eco-friendly and there are no toxic emissions
🌱 The maintenance isn’t not demanding and you can install some of the models on your own
Solar Pool Heaters Explained
A solar pool heater is a system that uses the thermal energy from the sun to make pool water warm. The solar collectors that are used for the heating of the water can be installed on the roof or set on the ground near the pool. They’re very similar to photovoltaic panels. In the case of a solar pool heater, the water from the pump goes through a filter and reaches the collectors on the roof. The collectors are similar in design and construction to the photovoltaic panels; however, they have tubes on the inside in order for cold water to flow through them and heat up. This heated water goes into the pool.
Thanks to solar heating, you won’t need to use fuel or gas to heat up the pool. In addition to going green, you will also save money in the long run, although the exact amount will depend on several elements, including the system’s efficiency, the upfront costs, the current heat source for the pool, etc.
How Much Will It Cost You to Install & Operate a Solar Pool Heater in 2023?
Data provided by the Department of Energy notes that if you want to invest in a solar pool heater system, you will need to spend anywhere between $2,500 and $4,000 for the installation. The period of payback for the investment is conditioned by numerous factors like how much you used to spend to heat up the pool or the cost of energy where you live. However, usually, most owners of a solar pool heater break even on the costs in somewhat less than seven years. The upfront payments are the highest costs associated with this type of heater.
On the other hand, the operation and maintenance costs may be $0 within a year if there’s no need for replacement of parts or repairs. A proper installation of premium quality solar pool heaters will operate efficiently for a decade to two.
What Is the Size of the Solar Pool Heater That You Need?
The size of the solar pool heater is an important aspect to take into account. The choice you make depends on several factors such as the pool’s size, the temperature you want for the pool water, the amount of sunshine that the collectors will absorb, etc. Even though you may install as many collectors as the space allows, if they’re not getting the needed sun exposure for the larger part of the day, the collectors won’t help you meet the heating needs.One general guideline is that the surface of the collectors should be 50 to 100 percent of the pool’s area.
Let’s make this simpler: you have a pool that is 200 square feet.The solar collectors need to have a minimum surface of 100 square feet. In some cases, especially if your home is in a climate such as that in Florida and the pool is active throughout the whole year, sizing up the system may be a smart choice. And, the opposite is usually done if the pool is used only for a couple of months in the summer season. Below, check out several size estimates for some common home pool sizes:
THE SIZE OF THE POOL
POOL SURFACE AREA
LOW-END COLLECTOR SIZE NEEDED
HIGH-END COLLECTOR SIZE NEEDED
10×20 ft
200 sq. ft
100 sq. ft
200 sq. ft
15×20 ft
300 sq. ft
150 sq. ft
300 sq. ft
20×40 ft
800 sq. ft
400 sq. ft
800 sq. ft
If you’re unsure about the right size of the solar collectors for your pool, contact the contractor. These professionals will advise you on the optimal system size by taking into account the pool specification and the pool’s location. Sometimes, particularly in areas where there’s shading or a lot of cloudy days, contractors may offer you to have a backup electric heater system.
