I'm looking to get one of those adapters that will change 55 gallon
barrels to stoves. I get free clean barrels that had coconut oil in them.

Does anyone have one of these? Single? Double? Much difference
between the two? Enough difference to justify cost?

It looks like it will take a lot of room. How much clearance do I need
around it, or do I have to build its own separate shed?
