The family of a high school friend had one to heat their house back in the late 70’s. When they moved out they gave me the stove, which was about burned out, so I put the parts on a new barrel every few years and have used it in my shop ever since. I made a grate out of re-rod but I still have the sand in the bottom.
Building a barrel stove from a kit is no big deal. A little cutting and a little drilling. That’s about it.
I agree with using the water heater and LP tank. Those would make a much more durable stove.
Other stoves I’ve seen were made from compressor tanks, section of culvert and a 275 gal. fuel oil tank.
