I have had a harman p68 for 3 years now. I have messed around with differnet pellets and settings on the stove. Im burning 5 ton a year in a 2200 sqft ranch. Keeping the house around 70 degrees and eating 2 plus bags a day. I have been complaining about the eating thru pellets since day one. I have had it set on thermostat and room temp. Laat night was the first night i turned my stove on had the blower turned just under half way stove temp at 1 and feeder set at 1 and it thru a bag of pellets in 12 hours. Is this normal. The place where i got the stove from said that everything is normal. It was 30 degrees lastnight and i qas using my heat pump as well
