I am brand new to this forum and really appreciate reading all of the posts, as I am shopping for a coal stoker stove to replace a very old one which has rusted as it has been sitting on a damp basement floor. I live in an older home, plank walls and kind of drafty, with the stove in the basement. No duct work, just holes in the floors. Do different models of stokers differ in the power of the blower/s? I like having the basement warm, and I would like to push more heat upstairs.
