We are planning to build a new home and shop. Both will have free standing wood stoves. I am looking for information on chimneys, essentially masonry vs metal stove pipe. We will have room for interior chimney which I understand will help produce some additional heat. Our biggest concern is safety as this will be our main source of heat in the winter and central heat to be used only as a backup. Any recommendations? The house will be using a Jotul F 500 Oslo and the shop will have Quadra-Fire 5700.
