Started a fire last evening about 6:30pm. Good pile of kindling to get things going then loaded her up 3/4 full with Silver Maple and Black Locust. Engaged the cat at #3 after about 15 minutes into charring the load. Had a real nice fire going with plenty of flame and the stove temps climbed rapidly so I cut back to #2.5 and continued burning for about 30 minutes then turned it down to 1.5 for the rest of the night. Basement temps rose from 68 to 74 and held steady once I turned it down to low burn. I was a little worried that I would be opening windows but it held at 74 all night in the basement and was a perfect 72 upstairs. This stove has awesome control! 8:00am still going with some good chunks of Locust in there. Stove top 300 with an active cat. I figure to just let it go til it's inactive and see what I have for coals and maybe reload depending on the weather.
