Can chimney stoves be used to heat coal stoves upstairs and downstairs?

Chimney stoves can heat the coal stoves upstairs and downstairs. According to the principle that air expands with heat and contracts with cold, we can know that hot air expands and rises, while cold air contracts and falls, and using a chimney upstairs and downstairs will not affect each other. Coal stove is a coal-fired stove, which is used for heating and cooking in northern winter. When burning the stove, the chimney can intensify the internal air circulation and make the stove burn more vigorously.
