My best burn time was 12 hours with a big chunck of black locust on a big bed of embers that just fit in the stove. my average burn is 6 to 8 hours if using oak and locust mixed. it is rated for 1300 sq. ft. and my house is 1500. It keeps my house between 70 to 80 f. with two windows open in the room the stove is in. My house is very well insulated. I only had one kick back problem in the two years I have had the stove and it was due to the hat on top of my chimney got clogged in the mesh screen from soil build up. This just happened about two weeks ago. I think it clogged because I milk this thing for those long burns and I have a real high chimney made of steel with a T in the pipe. My pipe up top doesn't get very hot on slow burns. The hat is from my fire place and has a spark arrester type screen in it. I was told to make the holes bigger in the screen just so a bird cannot fit in it and not smaller. Also I should clean the chimney two times a year because of the bend in the pipe. The T make for a very easy cleaning (about 20 minutes total clean up). Is your pipe coming out the top or back of the stove? Mine is in the back. I had to add a damper plate in my pipe because my draft is so good. Your stove should be the same as mine, so I would say your problem is in your chimney or draft and not your stove. I don't think jotul can make a lemon if they make a stove with a cast. It would be cheaper to fix your chimney problem before wasting money on another stove. Since it sounds like your problem will still be there if you ever got a new stove. Let me know what happens!
Good luck! Jim
