Commercial Pool Heater vs Solar Pool Heater

A commercial pool heater can cost you approximately $2000. However you can build your own at a tiny fraction of that price. Simply browse on the internet for guides that provide you clear instructions of exactly how to build your system.

There are numerous great products that you can rely on. One of them (I believe has been the best one called DIY Home Energy System by Jeff Davis. However, make sure to seek these essential elements at least, in any type of guide you purchase:

  • A clear list of materials with detailed guidelines
  • Materials must be easy to source in your area and affordable
  • No needs for complicated engineering, electrical skills or welding
  • Clear diagrams
  • Some troubleshooting pointers

How Do Solar Pool Heaters Work?

Solar pool heaters run on a passive solar principle. They merely, run through long sizes of flexible tubes. These are suspended in front of reflectors to get and transfer the sun’s heat to the water in the tubes. The tubes must be safeguarded, say with polythene sheet, from any wind chill.

The reflectors can be constructed of halved storm water piping, splashed with chrome paint to increase their reflective powers. To distribute this warmed water through your pool or spa you will certainly require a small pond pump or solar electrical pump. The latter is more pricey, however undoubtedly you will certainly aid the environment and your wallet by spending a little more to begin with.

One guide recommends that minimum pump specifications must be that it provides 10 litres per minute (120 gals/hour) and is capable of increasing water to 1.6 m (5’2″). All elements, consisting of tubes, reflectors and cover, are assembled into a photovoltaic panel.

Its perfect size depends on optimum dimensions for simplicity of handling, structural integrity and heating efficiency. Obviously more than one panel can be utilized. A spa would not require a big panel. However … some like it hot!


In general, a panel measuring 3.4 m (11′ 4″) by 1.4 m (4′ 8″) is effective on pools up to 30,000 litres (6000 {gal|girl}). Panels must be placed in such a way to optimize receipt of the sun’s rays. It’s ideal to have them face the sun’s mid day position. Put them vertically on a fence or horizontally on your roof.

To make the best of your solar pool heater, it makes sense to utilize it with a solar blanket. However this is not usually needed to benefit from your current upgraded asset – your pool or spa. Give it a go! Your family members will thank you for it.
