I tend to burn in loads instead of adding wood here and there. I don't know what my heating needs will be when the weather gets down to highs in the teens and lows around zero, but for now, If I were to keep the stove burning all the time. it would be 90+ degrees in the house.
Lately, I light the stove when I get home at about 6:00pm with a small load, get it going, let it burn down, and reload at 10:00pm for the overnight.
At about 6:00am, I smack the snooze a few times. By 6:30am, I'm stumbling my way to the stove to reload again. Depending on how I loaded the previous night, there may or may not be coals left. By 7:30am, the air is damped back, the stove is cruising and we're out the door to work.
By the time I get home, the stove is still hot to the touch, but there usually aren't enough coals to relight with, so I start from scratch again.
Lather, rinse, repeat.
