Got my corn furnace installed and fired up yesterday. My house has hot water base board heat. The furnace is a water boiler and will heat all my domestic hot water also. So far it seems to be working great. Will have to see how it is after a week. It dont seem to burn much corn yet, which is what it is suposed to do. I was on LP. With the cost of it rising I can cover the intial invest of the stove in 3 years.
