One of the first things we did when we bought our home was to purchase a new corn stove and have it installed in our basement so we could heat with corn versus the less than energy efficient all electric furnace that the previous owners had installed in the basement. Though it was brand new, it would have cost a fortune to heat the 1800 sq foot lower level.
So we had to bore through concrete to vent the stove and I tiled the floor so we would have a non-combustible pad for the stove, but now we have a multi-fuel stove in the basement that will burn corn, wheat, milo, soybeans, cottonseed hulls, cherry pits, rye..you name it. We wanted a stove like that so we could alternate between crops depending on what the market was. So far we love this stove! It works so much better than our old corn stove and starts so much easier.
Burning corn is so much easier than burning wood and so much less messy. Eventually we would love to add a corn burner upstairs and use it for our primary heat source. Right now we are using the wood burner for our primary heat, and we wouldn't replace it so we could have a backup if we lost power, but we would definitely prefer to burn corn upstairs. It's amazing how little corn it takes to produce a hot fire, plus corn stoves qualify for the Green Energy Income Tax Credit, so we can recoup up to 30% on our tax return! Bonus!
