How to build a solar pool water heater.
Step 1: What You Will Need
When you live in Canada, you need to turn up the heat in your pool all summer long if you want to use it.
First off, you need a location to install the heater. Preferably, if you live in the northern hemisphere, a southern exposition. The location should have as much sunlight as possible all day.
That said in terms of supply and tools , you will need:
L shape metal rods (or wood it you prefer)
2 x 64 inch 1 1/4 inch diameter copper pipes
3-4 rolls of 1/4 inch copper pipes.
Welding torch (bernzomatic, plumbers stuff)
Acetone or other cleaner that can remove soldering paste
