Heres what my stove looked like this morning.. This stove was loaded last night at 7pm for the overnight burn. I loaded it up really good. 2 of the splits were really heavy like 18lbs a pice not including the others that were put in. The wood was oak and super dense coming from a croch area. At 7.45 this morning this was what was in my stove.. thats 12.75 hours of burn.. I was happy with this
