How to Make a Solar Water Heater that Heats Your Swimming Pool

Making a Solar Water Heater to Heat Your Swimming Pool

Make a solar water heater, if you would like to swim in the winter time and don’t want to spend a fortune heating your pool with a gas or electric pool heater.

I’ve found a DIY solution!

I always enjoy watching Andy Bailey’s Ms Video Diary on Facebook.

He is visiting his brother in Australia where  it is now Winter.  He posted a video showing off his first swim in Mike’s back yard pool.   Wow  17 C  which translates to 62.1 F.  Kinda on the cool side.

Went looking around and found this great article by Matthew Sparkes
Technology / Solar Technology 

Which almost takes you by the hand in using discarded coils from old refrigerators to construct a very economical pool or water heater using Solar.

Actually he was sharing an article written and published on the Instructables….except the article has been removed.

Here is an  excerpt:

Instructables user, TheNaib, has written a tutorial on how to create a solar thermal water heater for under five dollars.

It will involve a fair amount of DIY, but nothing too complicated. It’s designed as a fun project, but with some tweaking it could see real applications,

“Its a great way to learn about using the renewable energy of the sun to produce useful effects, in this case hot water.

You can use these instructions to build a device that will actually heat enough water to use in the home, but it would require modifications.

“Not only is it creating hot water using completely renewable energy, but it is also created from recycled scrap parts like the coolant grill from a refrigerator.”

If you do try this out, be warned that it can really heat up water quickly, and to quite an impressive temperature.

, “A word of warning, this panel works VERY WELL. We tested it on a very sunny day and within seconds the water coming out of the panel was hot enough TO SCALD. I burned my fingers.

This very hot water is only formed when the water inside the panel is allowed to sit for about a minute without moving.

If the water is moving (due to the gravity siphon) the water exiting the return pipe is about 110 degrees, and while hot, will not burn you.”

I know from reading other suggestions for building a pool solar water heater, they can sometimes be connected to the pool filter pump system to move the water to keep if from getting to hot.

Another option is to just buy a small pump and make your heater stand alone, or use gravity… I f you use only one coil in a panel, might be easy to make it a gravity feed and eliminate a pump altogether.

As Matthew notes in his article,  TheNaib at the Instructables has some more suggestions and a lot of comments from others that have more ideas.

In the meantime TheNaib removed his project from the Instructables and has it archived on his own site.  Link is here.
This is certainly a very doable project,  TheNaib titled it

Loads of good information.  Nothing to buy, he salvaged most of his materials  from the local dump which recycles.   You might have one near you.
