In another episode I made a solar water heater with plastic bottles, but it was too bulky and low efficient. After thinking about that I show you this version simpler and more compact. You only need irrigation tubing of 16 mm and a piece of transparent plastic.
Because the pipe is black it absorbs a lot of heat and the trasnparent plastic above works as a greenhouse trapping the heat, like a car under the sun with the windows closed.
