What can we make with our dead water heater?
We have discovered a slow leak in our water heater, so we're getting a new one. The plumber will haul the old one off, if we want, but is there a cool way to upcycle the old one? All my searches come up with ways to upcylce other things into various kinds of heaters. We have skills in basic metal and wood crafting (we have friends who can weld/smith parts for us), soldering and wiring, and fiber use.
Any and all suggestions will be considered!
