I'm so confused by the chimney thing, a nice wood stove which I assume your neighbor is using because it's not practical or possible to heat your house with a fireplace can get you 70-80% efficiency and run overnight. They burn clean enough that I can't tell when my neighbors (presumably always) use theirs and they're directly across the street. The whole neighborhood knows when I use my fireplace.

My neighbors who heat their houses with wood (in an area where you absolutely don't have to—we have gas and electric at extremely reasonable prices), both have the nice high efficiency stoves to take advantage of the Biden tax credit and it seems to work just fine for them. Cords of wood around here aren't free but damn close to it.
