Black tarp, plywood, plexiglass, tubes, clamps, and a bucket is all you need to make a thermosiphoning Simple Solar Water heater according to Renewable Energy UK. This set up looks a lot like a maze. Except instead of a little ball, water shoots up through the small space between the plexiglass and the tarp. As it heats up, the water passes over the hot black tarp surface, disinfecting it. It travels upwards (known as thermosiphoning) as the temperature increases which increases the flow and therefore gives pollutants in the water a longer time to decay. ┬áThe tubes connect the water in the bucket to the “maze” and are clamped in place. This setup is an estimated $30 but can also be made out of recycled parts. Some designs attach the water tank directly to the “maze” without using tubes.
