37 bags since Oct 24. So far medium on almost as low as you can go is maintaining well right now keeping the house at 70 even in mid 20's outside. We'll see as it gets colder. Burning Made in Maine Hardwood from TSC. Trying 3 bags of Green Supreme from HD (blend hardwood and softwood). Any reviews on Green Supreme. My father has just gotten his Quadrafire Classic bay 1200i. He is burning with these for the price and because *I* was told they burned good. He is getting alot of ash buildup in his burn pot. I believe even might have caused a shut down. I told him he is just going to have to clean it every day or every other day. I'm going to give him a couple of bags my hardwood and see how the ash content and how it burns for him.
