By placing the fire and chimney on opposite sides of the house and constructing a tunnel between them, heat is pulled through the tunnel, heating the floors and helping distribute heat more evenly.

How is airflow achieved? In a traditional fireplace (or rocket stove) hot air rises up a hot chimney to draw smoke up or create pressure to push smoke through some ducts. How is that happening here?
It’s not totally clear from the diagram, but I think the fire pit itself is outside the house. The air naturally ducts underneath the floor of the house and then up the chimney in the back. There’s still a chimney effect, but it gets redirected under the floor first.
