I just put 2 or 3 peices of 16" hardwood in my stove for a fire. I like smaller fires and am not looking to heat my entire house, just a section of it. When I feed my stove the wood, I would say I fill about 1/3 of the interior of the stove. I hear many discussions on this forum about packing the stove with lots of wood for longer more efficient burns. My question is ..... when you are gonna pack your stove tight, how much interiior area of your stove should be filled ?
