The Simplest Solar Water Heater

Carl came up with this very simple and effective solar batch heater that heats up one bucket of water. You put the 5 gallon bucket into the glazed box, put it in the sun, wait a few hours, and then take the heated bucket of water to where you need it.

Perfect for a cabin, emergencies or just locations without running hot water.

Its mounted on a turntable, so its an and advanced tech, human powered tracking solar water heater!

A piece of foam cut to fit the bucket reduces heat loss from the water surface.

Very nice and very simple.


In one test, the bucket water heated from 53F to 122F over a 7 hour collection period.
