this is my first season burning my new 10 year old Oslo 500- it sat for the last 7 years til i bought it from a friend, so its in great condition. i know everyones setup is different, so will the burntimes. like jotul says, its the chimney that makes the stove work. my average burntime overnite is around 5-6 hours. any more than that, and the coals are almost gone.
here are my variables- most of my wood is a mix of oak, locust, maple and ash all seasoned around 10 months? i'll load it at night after it gets hot and its ready for the "midnight load". i'll throw 2-3 big splits in with room for 1-2 more but refuse to because it burns too fast/hot even with the air lever shut down all the way. one night i loaded it like that and continued to watch tv and watch the fire. in one hour, the temp went up to 650 and climbing- is that too high? i grabbed the splits on fire and yanked them outside- FUN! so i'm scared to fill it up at night. i changed ALL the gaskets with little or no change. i have a 90 elbow inside and a 90 elbow outside with a 22' excel stainless double wall 6" chimney. its 2-3 feet over the peak of the roof. we live on top of a mountain, so its breezy up here. could i have too much draft, making it burn too fast. but how could that be if turn the air lever down all the way?
is there anything i can do to slow down the burn and get another 2-3 hours burntime? what about a damper in the inside black pipe? could my air lever control be faulty? i would get 8-10 hours in my last house with a hamton 300 insert, so i'm not new to the wood, just this stove. what are you guys getting with your Oslo's? any suggestions would be greatly appreciated. thanks, Rune
