We've begun the process of removing the old zc fireplace and replacing it with an alcove and free standing wood stove. This will be our primary heat source when it's finished. Still deciding on the stove, probably going to be a Jotul F55 or Kuma WC. We're also busy picking out rock for the walls and raised hearth. I will be doing most if not all the work myself and this forum has been an great source of information. Wanted to say thanks and share a couple of pics of the progress.
