stove pipe, double vs. single wall
I recently purchased a home with a wood stove insert in the living room fireplace. I want to line the chimney before I start using it, as the condition of the chimney is questionable. My plan is to use double-wall stove pipe to line the bottom of the chimney, and single wall for the section that is above the roofline. Is using double-wall pipe an overkill, or is it a good idea in this situation? I would rather err on the side of safety. Also, what will I pay for double-wall and single wall pipe, I want to make sure my local stove store is not overpriced.
