"Why heat with corn?" The question really is "Why not?"

Corn is a locally produced, renewable energy resource. It burns clean, leaving very little ash, and its chimneny exhaust is easy on the environment.

When corn is burnt completely, three main things are left behind, water ( in the form of water vapor ), carbon dioxide ( CO2 ), and carbon ( the ash left in the fire pot ). Water and carbon dioxide are used by the next corn crop as it grows. Carbon is an excellent soil ammendment ( fertilizer ) and good for plants, no matter if used in the home garden or returned to the corn field.

Local energy is good for everyone. Not only does it keep transportation ( and its costs ) to a minimum, but it also keeps the money in the local economy. Instead of the money going to people in other countries, it goes to a neighbor, who will likely spend it locally.

Corn is also energy dense.  At an average of 7000 BTU per pound, the standard bushel (56 pounds of corn, about the size of a regular laundry basket) has a lot of energy for its price.
