A foot stove consists of a wooden box which is open on one side, with holes or a slab at the top.
In it, a bowl made of pottery or metal with burning charcoal was placed.
The feet were positioned on top of the stove to become warm.
By putting a blanket or clothing on the legs the heat could be isolated and the lower legs were heated.
Foot stoves were used in Northern Germany, the Netherlands, and the United States.
