Chimney Draft - Rumford

The stack effect or chimney effect is the movement of air into and out of buildings through unsealed openings, chimneys, flue-gas stacks, or other containers, resulting from air buoyancy. Buoyancy occurs due to a difference in indoor-to-outdoor air density resulting from temperature and moisture … See more Since buildings are not totally sealed (at the very minimum, there is always a ground level entrance), the stack effect will cause air infiltration. During the heating season, the warmer indoor air rises up through the building … See more Two regimes of stack effect can exist in buildings: normal and reverse. Normal stack effect occurs in buildings which are maintained at a … See more There is a pressure difference between the outside air and the air inside the building caused by the difference in temperature between the outside air and the inside air.

WebSometimes called the chimney effect, the stack effect is a naturally-induced vertical flow of air through a structure. In low-rise structures, the effect is often small enough as to be … WebA better insulated chimney will keep flue gases hotter and moving faster, so it will produce better draft. A roof exit keeps more of the flue system inside of the heated envelope of the structure, so it will tend to keep flue gases hotter.
