Can't seem to master a true 8 hour burn out of my Pacific Insert (one that continues to maintain the heat of the home through the night). For example, last night I added fuel around 10:30, charred the splits real good and gradually shut air intake to lowest setting and went to bed at 11:00. Upstairs thermo read 70F (floor above the insert). Got up this morning around 6:15 and thermo read 61F. Not too bad for me, really, but kids were cold. Good thing was had some pretty great coals, so within a few minutes had it up and roaring again. Here is my question. Last night I woke up once in the middle of the night and thought "I should just go throw in a couple of small splits." But, if I were to have done that, I would have ended up opening the air, charring the new splits, then waiting a bit, closing down the air gradually and then returning to bed. It would have taken me 1/2 hour of my sleep time. What would happen if I threw a couple of splits onto the fire, left the air closed, and just went back to bed? Would it smolder for not having been charred? Is there anyway to quickly stoke fire if I wake up in middle of night without spending time charring splits and opening and closing air, or am I just best to wait till morning and get her roaring again? Thoughts?
