Solar swimming pool heaters have one the quickest payback times of any alternative energy investment. My biased opinion is that any swimming pool owner should use a solar system.
Because most people only use their swimming pool when the outdoor temperatures are above freezing solar pool heaters have a much simpler design than systems intended to provide hot water for household year-round.
In essence, a contemporary solar pool heater is little changed from the first solar hot water heaters of the late 1800s.
As all pool owners know, pumps continually circulate the water of the swimming pool through filters and the heater. With a solar swimming pool heating system, a solar heater replaces a gas or electric heater.
Since the pump and most of the rest of the plumbing is required anyway, the additional cost of the solar system is minimal.
The principle of most solar pool heaters is simple. You’ve seen it demonstrated if you’ve left the garden hose full of water laying on the lawn on a sunny day. When you next turn on the hose, warm water will come out. That water was heated by the sun.
A do-it-yourselfer could make a workable solar pool heater simply by coiling a long length of black plastic piping, placing it in a sunny spot and connecting it to the pool system.
The advantage of commercially produced systems is that they generally are need an appearance and include such niceties as flow control valves and sensors that will automatically bypass the solar heater if it is not warm enough.
You can learn about all forms of alternative energy (Alternative Energy Primer).
There’s a great page on that site that gives you a lot more information on solar pool heating,including factors you need to consider when designing a system how to properly size the system and some excellent resources for commercially available solar pool heaters. That page is:
If you have a swimming pool, using the energy of the sun is a win-win situation. It extends your swimming season, save you money and saves the environment. I hope you’ll visit the site above to find out more. They give examples of just how much money solar pool heating saves that I think you’ll find impressive.
Enjoy your pool, but take it easy on the environment while you do.
