Far more complicated than that. Chimney design, firebacks, and fireplace vs woodstove all make a big difference.

Simple thought experiment, if that were definitely true of every design our ancestors would have all frozen to death. Heated the ranch house I grew up in with a woodstove as the only heat source for most of my childhood.

thought experiment failed

woodstoves work, the scam is they use more wood than a fireplAce.

you're not logicing well byeeee

The opposite is true. A wood stove keeps far more of the heat in the house than a typical north american fireplace design.
