WOW. I am impressed.
Last night I built my first fire in it with some cardboard and a small arm load of seasoned sycamore that was split up pretty fine. It took it roughly an hour to get to 155. I then went back out to the stove last night around 9 and put in one piece of seasoned sycamore roughly 10" diameter, and beside of it I laid about a 10 pound lump of coal.
All night long I kept telling myself I didnt put enough wood in the fire, lows here were in the 30's. However, I noticed the fan in the house wasnt running longer each time as it would when the fire is cooling down. So at 9:30 I went out and was amazed at what I saw, the 10" sycamore piece was about 70% gone and the coal was still burning as well. Most of the small pieces of sycamore were gone but it was a longggggggg ways from going out!
I am really impressed with this unit, with the fully adjustable air control on the back I'm looking forward to playing with it. I have them both set about half now and its performing great, if you open the door with the fan on you can clearly see what a big difference the air blowing into the top of the fire makes. I know it's not a gassifier, but it's very impressive to how cleanly it burns with the fan on.
Looking forward to a longggggggggg cold winter!
