What is the difference in the kind of heat between the two since they are different materials? Right now I am heating 100% with an old Fisher stove and it heats me out some nights in January, so can I expect the same from either these two stoves, and which would be better in my case? The stove sits in my basement and radiates up, to the living quarters, so I am mostly concerned about just heating as good as the old Fisher if not better. What do you guys think?
