My Mom and Dad have a corn stove. They opted for that over a pellet stove because in a corn stove, you can burn wood pellets too, but you cannot burn corn in a wood pellet stove or so they were told by the dealer. they get their corn from a farmer and bag it themselves, but I think any field corn either from Walmart, or feed store is fine. If you will run it around the clock, be prepared for alot of corn, though. it only feeds in a few kernals at a time, but all the time, so it will go through it faster than you think. "Klink" (ash) is minimal, and easily removed from the fire box. He's got an insert and flu's it out the chimney. Mom and Dad love theirs! Oh, and btw.. sometimes it does pop the corn.. only a few times, though.. but it's funny to see that. I'd like a pellet/corn stove too, if only to not have to do all that firewood all the time.
