I installed a Breckwell Big E in September, and have been running it as needed day in and day out, 24/7 since we got it. I have friends with both corn and pellet stoves that have had them for a number of years and say that ours is quieter, heats better, and seems to be more effecient than theirs. We have only turned the gas furnace on twice this year, while it was really cold when we were cleaning the pellet stove. Otherwise I have not had my gas furnace kick on at all. The stove is heating a 2000 square foot 100 year old drafty farm house and keeping it at 65-68 degrees set on no higher than 3.
