I've been burning for about 16 years with a Fisher insert, but would have to use propane as my main heating. About 4 o 5 years ago I added on a bio-mass furnace love it heats the house really well. Never completely happy I changed out the insert this year and have not burned any propane or corn to date. So far the house has only gotten down to 62 and that was an over sleep. I've got $900.00 dollars sitting in corn and have not spent a dime, (well maybe about 20 bucks for gas in a saw) and keep the house around 70 to 74 all the time. Could of saved some money if I would of put the new insert in years ago.
