How difficult would it be, or is it even possible to remove my OLD woodstove insert and replace it with a freestanding woodstove? The insert I have currently has fans underneath and I can regulate the speed with a dial on the side, would I still be able to use that (or some form of that) with a freestanding stove so I can circulate the heat through the house? Or is this a bad ideal all together! It seems that freestanding newer models generate more heat than inserts and are more efficient. Any help is greatly appreciated!!
