While three stoves was probably ahistorical for most homes, a fire which heats the home and is also used to cook (food in ceramic containers) was absolutely commonplace. In particular, a controlled cooking fire in the center of a single-room thatched-roof home was the template for much of Europe, Asia, and for some of the North American natives, albeit at different points in their history.

Franklin stoves sold like hotcakes too, didn’t they? As an improvement over the hearth and the pot arm, which were themselves improvements over the three stone fire (which is still used by an alarming number of humans today).

Of course.

Worth mentioning also (moving away from the poor now) wingback furniture, flannel pajamas with caps, canopy beds, bedwarmers with hot rocks or coals from the fire, three-piece wool suits during the day, etc...

They might not have had an oven, but they certainly had a fire of some kind.
