Hello! I bought a home two years ago with an Austroflamm Integra(?) Pellet stove insert. It is in the lower level of a raised ranch which has a large opening to the second floor. It is intended to supplement heat only 1 level. Unfortunately, it does not even produce enough heat to make my approx. 15X20 family room comfortable. It seems to heat within a 3 foot range of the stove itself, and that's all. Also, we get a lot of soot on the glass door every day, and I am not sure that is normal or not. My husband cleaned the stove thoroughly last year, but that did not rectify either of the above-mentioned problems. We have heard nothing but great things about pellet stoves, but we are very frustrated, and considering taking out the Austroflamm insert and returning to wood. If there is anyone with any advice, I would appreciate it!
