here's my question: a two story house. a small woodburning stove in a 1st floor room whose round metal flue passes through the floor and into the 2nd floor room, heating it as well and then the pipe moves out into the attic and roof via a brick chimney that begins in on the attic level. My question is, can I place a second similar wood burning stove in the 2nd floor room and connect it up with a T-joint to the existing metal pipe? Or is this a big no-no? would it screw up the drafts etc.?
