Corn stoves are popular around here, same principal but use corn vs pellets. My in-laws have one. Originally they put it in to heat their basement but discovered it provides quite a bit of heat for their upstairs. They use very little propane in the winter now. They have the corn delivered. They live in an older house that has a coal room complete with the old coal shoot so that was handy for them. No shortage of corn to worry about around here either.
