Old rural houses where I'm from were basically a huge kitchen/dinning room build around this kind of a stove + the rest of the house. The oven heats water in pipes going through the masonry and they heat the rest of the house through radiators. And then you also use that water for bathing.

So you cook in the evening so that you have hot water for bathing before going to sleep and the house is warm through the night.

It also has warm shelves near the ceiling used for drying clothes/shoes/fruits/mushrooms.

Very efficient, but it means the whole house is build around it.
