One thing I have noticed about our Non-Cat Pacific Energy Summit, the burns are a lot more efficient with better heat output using smaller sticks of wood. If I am going to load it for a strong overnight burn, I use larger stuff, but make sure I'm running at least 550* F outside stack temp for a few minutes before reducing the draft. Oodles of coals in the morning for a quick start.
I like to watch the flames also. I didn't think having a glass door would be that big of a deal, but I sure enjoy the woodstove a lot more with the visual aspect of the experience.
