Homemade Solar Water Heater

Heating water is often an energy ignored when it comes to solar energy but one of the easiest to create, this system has been done using a couple of old solar panels, obviously no longer working but work great for heating water. You can’t really see what they have done inside the solar panels but there is a grid formation made up of pipes for which the water flows through. I like this video though as it does show how quickly the system can work and how easy it is to form up.
