cold air feed
I'm tossed between a passive air input tube and forced air...
Fans and impellors are a hassle to size and run, but fire draft will draw air in from SOMEWHERE, best if from a desired source.
Everything I read about fireplaces says using heated house air for combustion decreases efficiency and limiting air limits combustion (some help) but cools the smoke and makes creosote buildup more likely. Wish there was more discussion on this in the marketplace - I think the idea is to sell 'pretty' and let the customer figure out the 'just open a window some' solution.
