While I do agree with you, you'd be not-so-impressed with what I'm pulling off with great results. IE, no creosote buildup in my chimney at all. Just flyash. I have a 6" make up air duct DIRECTLY attached to my barometric damper on my stove pipe. So I'm regulating my draft with cold outside air so I'm not sending heated basement air up the chimney to do so. It's nice having a furnace which burns pretty much all smoke so I can pull things off like this.
fire and problem with newer homes - laminated / structurally engineered beams- from what i have read and been told not a good mix.
A floor vent with a vertical duct built down to within 6”-8” from the stove room floor will allow cold air to sink from the room above and not create a chimney effect in the horrible case of a house fire..... It will greatly improve convection, with heated air rising up a stairwell- that cold air blanket that folks encounter in rooms far away from the stove is eliminated, without a fan (when heating from below). This works great for us.
