I've been using a Drolet Savannah for 3 years, and it has served me well. Its a great little stove, but the firebox just isn't big enough to give the burn times that I want. So I've been planning on upgrading to a larger stove. I've been happy with the Drolet brand and was looking at their Baltic model. However, I have also been considering switching to a coal stove. Does anyone have any experience with coal stoves? I grew up in the North West and now live in S.W. Pa, so I've had plenty of experience with wood burners, but know virtually nothing about coal stoves. I've read on the net that you can get 24 hour burn times with a coal stove, is that common? Also, how does one store the coal? Can it get wet? How much coal do I need? If I get a coal stove, can't I burn wood in it when I don't need the long burn times? Some recommendations as to coal stove brands would be great. I'm not looking for anything automated that needs electricity to operate though. And, price is, as always, a consideration. Anything you guys can add would be a help.
