I posted a few pics and questions regarding my cabin at 10,000 feet last month. I appreciated the spirited comments and discussion. I sold my jotul oslo and installed a PE alderlea t6 last weekend. I got a chance to fire it up over the weekend and WOW, what a difference. The cabin got to a toasty 80 degrees after 2 hours. I'm sure it's the efficiency of loading wood. The front loading north south configuration allowed me to easily triple the wood load. Same wood, same chimney, same cabin and easily 15 degrees warmer. Thanks for all the help. Kudos to Tom Oyen. He was right on the money with his recommendation.
