Fired up the MK II on Friday night. Getting 24 hour burns quite easily. Temp on the side of the stove is 250 deg, on top of the blower channel is 150. Amazingly, I can hold my hand on the exhaust pipe 8 inches behind the stove. Using 1 hod per day, looks to be about half of a 50# bag.
Love the stove, yes, the ash tray is an issue, but I've nothing to compare it to. The stove does best just humming along at around 350-400 deg. When it gets cold and I try to keep the stove temps higher, it requires much more attention. Anything above 400 deg requires at least 3 loadings/shakings in a day. Whereas the usual number is 2 per day.
I start burning around the middle of Nov, and usually stop around the beginning of April. Last year I burned 5200# of coal. Little more than 2 1/2 tons. This year, coal costs less than 1 fill up of my neighbors oil tank.
