What an awesome re-purpose idea. Convert an electric water tank to an outdoor wood stove. Water heaters seem to need replaced after a few years so why not put the tank to use for a stove instead of sending it off to take up sapce in a land fill. Instructables website shares a great project of how convert an old electric water tank into a outdoor wood burning stove.
People are always looking for ways to create something useful from something they would have throw away….upcycling.
