There is a lot of good advice here. Coal burning is more of an art to burn correctly than any other type of fuel. As a result, there is a big learning curve when you first start. My wife was not too sure about coal when I brought up the idea a few years ago. She poo pooed it at first but now she loves it, and remarks how it was a great idea. Now, even when I’m gone for a few weeks for work during the winter, she can start it up and keep it burning nonstop. We don’t use our baseboard heat anymore!
Keep the faith, you’ll get it. Your wife may even start to like it too.
As a relative newbie to coal myself, I reiterate these comments. Once you figure your stove out, its fantastic. Its like riding a bike, once you "get it", you never forget.
I fired up my stove last week for the first time since Spring on a particularly cold day and it was far, far easier than the wood stove it replaced.
Cant wait for cold weather to get it going 24/7 again.
