Does anyone have any experience or thoughts on installing a damper to help with a cold start? I'm thinking of installing one on my build but wasn't sure if it's overkill or a smart thing to do and more specifically where to put them without getting in the way. The Wisner's touch on this only on one or two pages but not a lot of information out there.
A standard damper, to close off the chimney, would not do anything good for cold starting; but a bypass damper to let the exhaust go straight up the chimney instead of winding through ducts or bells could make a big difference in ease of starting the fire when cold.
The usefulness would depend on the specifics of your house and installation. If you get good draft even when the fire is cold, a bypass damper may not be worth the effort and complexity.
