We are laying out the location and pre-fab chimney for our little VC Aspen stove. Right now, there is an old clay thimble going through the wall behind the stove that we could insert a doublewall thimble into and exit out the back of our stove. It would seem convenient but i read that having almost all the pipe outside the home would not be very efficient because the pipe wouldnt build sufficient heat. My alternative would be to abandon the clay thimble and go straight up through the roof since its a single story. It would probably be cheaper since the length of triple wall chimney pipe would be minimal. The downside is having to cut a big hole in my roof. How detrimental would it be, draft-wise, to pass straight out the back of the stove to the outside? Sent from my SM-G970U using Tapatalk
Straight up always drafts the best. You'll want to use class A double-wall insulated chimney pipe...its better for wood burning than triple-wall (air cooled) is...stays warmer and cleaner inside...especially for outdoor pipe.
