I have a 2 year old corn furnance for sale. I only used it about 4 weeks total. I never had the money to buy the corn. Works GREAT. Hooks up to your furnance so you can use your thermostate in the house. Heats over 2200 sq feet. I paid over $4000 for this. A new one the same size costs over $4000 plus shipping. Burns corn, wood pellets, cherry pits and can be converted to burn other things. I dropped my price from $2850 to $2600 OBO.
