Figured out that we burned 150 or so gallons of fuel oil since october. We had a cold winter, with no real warm ups to speak of. Kept the stove going around the clock, burned about 4 1/2 cord. Furnace kicked on some, but only early in the morning, generally just on very cold nights. No, I do not get up in the middle of the night to load the stove. Way to lazy for that. Most of our oil consumption was for hot water. I figure I saved at least $1500. And that's being very conservative. Probably over $2k. Stove has just about paid for itself in 3 years.
