I believe this has been asked in various threads but I haven't really come across a solid answer.
My family and I are in the process of moving into a new house with a full basement in which I will be building a Peterberg Batch Box (or equivalent). For the size of the house I've settled on an 8-inch system-size.
The house doesn't have a chimney so I will be installing a "Class-A" double-wall insulated chimney. I'm constantly fighting the "bigger is better" urge and trying to decide between 6 or 8 inch.
Here is an example of the chimney pipe I'm looking at, available in both 6 and 8 inch sizes:
a.co/d/6P6tmD0
The chimney will be 16 to 18 feet tall, outside the building envelope.
I've read conflicting info on the web (or just as likely I'm misinterpreting what the pros are saying) about chimney sizing. From what I've read, the smaller-diameter chimney will produce "more draft" while simultaneously not being able to "draw enough" to service a larger stove.
Those seem like conflicting statements - which is likely where my misinterpretation is coming to play.
I've always been under the impression that a larger-diameter chimney will produce a stronger draft which is why I assume the 8-inch chimney will "future proof" the system vs a 6-inch chimney.
I've run 6-inch PBB's on very short, poorly insulated, "subpar" 6-inch chimneys without any issues. I always include a bell bypass to help with cold-start. With just that experience it seems an 8-inch system feeding into a much much better 6-inch chimney will likely work but I would hate to spend the thousands of dollars on a chimney just to find out it's insufficient.
Can someone set me straight on this?
