The Best Guide For Buying Solar Powered Pool Heaters

When we talk about pool heating and solar pool heaters then these are a far better option than the electric pool heater or gas pool heaters in terms of cost and durability. Though, old solar panels can also be used for heating a pool, going for a new and properly installed pool heater is recommended. Evaluate a few points before finishing your purchase.

  1. The amount of sunlight your place gets where you stay
  2. Any local codes or regulations, if any, to be researched beforehand
  3. The efficiency and size of the heating system you and your pool require
  4. The angle and place where your pool heater collector has to be put should be figured out
  5. Comparison of cost and prices of other variants

This becomes vitally important that your solar panels will receive how much heat, when put to use. As, the solar pool heaters harness the heat of the sun for keeping your pool as an oasis, so this factor becomes of great concern.

Now you must be thinking that it would have been better if you were staying in a place like South California or Arizona and would have benefitted with constant sun rays. You can just keep your worries away, as shaded parts in your backyard will also receive the rays of the sun and work well for your solar pool heater. The quality pool heaters assist in collecting direct and diffusing solar energy. This depends on the pool heaters’ design, efficiency, and collector for the best results.

Determining Your System Size And Related Factors:

  • The size of the pool
  • Availability of solar energy and its amount
  • Pool temperature you desire
  • The average temperature of the place you reside
  • The efficiency of the system
  • The solar cover you plan to go for or not

The size and system requirements depend on the surface area that needs to be covered by your pool. On an average surface area of 50% is required equivalent to your pool’s size for proper heating benefits. In case you stay in a place that remains cloudy or cool then more surface area of panels is required to be covered. 

Hot places or Northern places often make optimum use of the sun heat for almost six months, but places like Florida or others require large and additional panels for the use year around. The use of solar pool covers help in the reduction of the panel size while performing best. Henceforth, this is a good idea to go for, irrespective of the place you stay.

After determining the pool size the size of the pump has to be considered. In case the pool owner is thinking of switching over from a gas pool heater to a solar one then the need for additional or large pump arises for perfect outcomes.

Finally, come to the cost and installation factor that also cannot be overruled. The solar pool heaters available are very convenient to install and are available at affordable prices. Maybe some expertise and additional costs have to be incurred, but no issues as you are heating up your dream pool and turning it into a beautiful backyard oasis.

The Solar Pool Heater’s Working          

The solar pool heaters work with the help of a flow control valve, solar collectors, filter or a pump. The water of the pool is pumped by a filter and then it makes its way through the tubes of solar collector, gets heated up and is returned back to the pool. The pool water gets warmed for your use while it passes through these tubes. In hotter places, the pool needs to be a little cooled before use, and the system can make this process happen at night also for circulating the pool’s water.

Some of the pool collectors use sensors and water diverter valves. They are efficient enough to change the water’s direction when the collector’s temperature becomes more than the temperature of the pool. While this happens the collector’s temperature and the pool’s temperature tend to be the same and the water is pumped back when it bypasses.

Different solar pool heaters are constructed with different materials, and the climate of the place you stay will decide the same. Before buying a pool heater check for its material as it will help in performing better.

Panels that feature unglazed collectors are most useful where the grounds don’t have snow in winter. The unglazed panels without glass covering are supposed to be the best, and these also feature a rubber- construction and heavy-duty plastic. The ultraviolet light inhibitor helps in enabling it to be more durable and sturdier. These unglazed panel systems are more popular and preferred due to their simplicity and economical quality. As a pool owner, you can definitely go for this kind of a solar pool heater for optimum results.

The Installation Process Of A Solar Pool Heater

When it comes to installing a pool heater, this can be an easy-breezy or annoying challenge. Though it’s not that complicated a few procedures are required for making the installation a successful affair. The modern-day solar pool heaters are designed with uniqueness, let’s dive into the process:

Step 1

It is very important to make sure that you choose the pool heater of the right size. As mentioned above also in the article a solar pool heater should possess a collector panel that has 50 % less surface area as that of your pool size. The general rule of thumb should be adhered to. So, go for the right sized pool heater to avoid any future hassles.

Go for the best pool heaters after researching and considering the varied factors.

The Pool Types

As the pool types are different so is their heat losing capacity. Henceforth, above ground pools tend to lose more heat than the in-ground ones. Solar collector panels that have more surface area are recommended for pools that need to absorb more heat for keeping warm.

The Efficiency Of The Pump

An efficient pump facilitates more heating in less time by giving its peak performance. The pumps with more running time prove more beneficial and the solar collector with less surface area can be used for returning the heated water to the pool. It’s wise to go for a pump that performs best.

The Solar potential

This is directly related to the amount of sunlight absorption done by the solar panels. While using solar thermal power the pump will consume less energy if the heat absorption power is more. The playback time increases with this feature which is facilitated by a good solar collector. The glazed solar panels are effective and work well in the regions that have winds flowing.

Direct sunlight when it comes in contact with the solar panels, performs best. Hence, a well-lighted area that gets the sunlight in maximum quantity is absolutely ideal for installing them. Some of the pool owners prefer to pace them on the rooftops, there it should be kept in mind that the water flow resistance should be minimized and the wind should be avoided by keeping the panel away.

The collector panel can be made functional by cutting the PVC line after the filter and establishing a connection with flex hoses. The positioning can be done in a flat way or can be tilted in order to have absorption at peak.

After the connection of the solar collector is made with the pool pump. later on, the diverter valve should be installed. The solar pool heaters that are available in the market these days come with water diverter valves. The manual or instructions can be referred to before installing according to the model you buy.

The valves help in making the water flow completely and exclusively through the panel and restrict it when open, thereby giving you complete control to monitor and have the apt temperature of the pool. All the solar pool heating systems come with different construction but are likely to be installed as quickly as in a few hours.

The last verdict

By now you must be clear about the efficiency and benefits of a solar pool heater. You can easily choose a pool heater with the help of the points mentioned in the article above. Get a quality solar pool heater to enjoy extended pool time, while fulfilling your swimming passion. Get your pool worthwhile even in the freezing temperatures. Solar pool heaters work great for this with minimum operating costs.
