A potbelly stove is a cast-iron, coal-burning or wood-burning stove that is cylindrical with a bulge in the middle.[1] The name is derived from the resemblance of the stove to a fat person's pot belly. Potbelly stoves were used to heat large rooms and were often found in train stations or one-room schoolhouses. The flat top of the stove allows for cooking food or heating water.
