Last year I found that burning my super classic 24/7 produced a large amount of overnight coals which would easily start a fire the next morning. The problem is that these coals would not produce the same heat as a full load of wood and would soon reduce the amount of space for more wood requiring me to empty the stove.
My solution now is to divide the box into left and right using one side for splits and the other side to burn the coals to ash. As the splits are burnt to coals, I move the coals over to the other side allowing them to burn to ash. When one side is mostly ash, I reverse the procedure. So far I have been able to increase the amount of time between emptying box and decrease the coals. Seems to work.
