I know it's been in the single digits the last few days here in Central Mass, but I am a (negatively) surprised at the performance of my stove. This is my first season with the appliance (started burning in mid-Nov '12), so I just want to check I am doing everything I can. My home was built in 2003, It's 2400 sq ft. The fireplace is in the family room, cathedral ceiling with fan running. Laser thermo gun confirms warm air is not pooling in up high. I have been burning Okies since the start. I calibrated the flame height per the manual and found that -4 worked best. The stove is perfect when the temps are > 20F. I only use it on manual mode, but I can set it to 3, 4 or 5 as I need to based out outside temps. In these days the family room would get into the low 70s and the kitchen, where the controller is, high 60s eventually hitting the set point of 71F if it is warmer outside. Now with the frigid temps I have the stove on 5 Manual. In the morning the family room is 66 and the kitchen 63. I can't understand this. I thought at least the family room would stay warm. I switched to Blazers after a good clean down of the stove and these render +2 degree benefit in the family room. I have read about all kinds of settings e.g. -5 Corn. Has it really come to this, I am thinking? I would appreciate any thoughts folks might have. Perhaps my expectations were simply too high and need to turn on the oil. Thanks. Greg Some misc stuff: We're good about cleaning it. We clean every two days with ash vac. We have OAK We did the baffle after the first ton, per the manual. In total we've burned 1 ton + 20 bags. The controller is about 20 feet from the stove, but I have an 'stat for the oil in family room, which is where I take my reading. I have check it agreed with thermo. The opening from family room is about 12 x 8.
