I have a Harman SF 160 coal boiler. I run this boiler every 8 hours. I shake and add new coal to it. I never had a fire go out yet. If I tried to get 12 hours out of it I would have to fool around with wood to get it up and running again. Running a coal stove is all different then using wood. You have more ash and more cleaning to do. I fill mine up to the top of the firebrick; I also use nut coal. I keep my electronic damper set on a very low setting. I maintain 195degree water. My stovepipe temp never gets above 200 degrees.
