Instructions.

 

The first thing you will have to do is collect enough PET bottles to carry out this project. Everything will depend on the capacity you want for your heater. The more capacity, the more bottles you will have to use.

 

I recommend you start with a small project, where you will learn enough technique to undertake larger projects.

Preparing plastic bottles.

 

You must clean the bottles, remove the caps and labels. Leave them clean, as you work with them you will appreciate it 😉

We prepare the bottles.

 

You must make a hole in the base of each bottle that you are going to use, of a size enough to pass the polystyrene pipe that we are going to install between them. It should not be larger than the mouth of the bottle, since the spout must pass through it so as not to complicate the installation further.

Threading the polystyrene spout through the bottle.

How it works.

 

Its general operation can be seen in the following bullet point. But in a simple way we can say that a solar heater works like a heat trap, where solar radiation is trapped by the greenhouse effect inside the heater. These heaters do not need external power to operate. They use the principle of convection to move the water.
