I have to say it, I have been on other helpful forums on the internet, read a bunch of library books, but this website is really the most helpful when it comes to heating with coal. Nowhere else is there a group of real world coal burners giving real world advice like this. No way would I be burning coal without this forum, I didn't even know about coal boilers a couple years ago, I thought they were all just old asbestos packed inefficient junk from the bad old days of dusty dirty hazardous heat. Thanks guys for showing me the way, we have been so warm this winter it's truly a blessing to see the kids keeping their extra blankets folded up. Last year they needed 4 or 5 blankets and I worried about them getting sick, I couldn't afford the propane to keep the house above 60 during the coldest months. We were literally freezing and going broke, this year we are all warm and it's much more affordable. Thanks again.
