Condensation occurs when moisture-laden warm air strikes a cold, dry surface, such as a basement wall or window. A similar thing happens with cold water passing through copper pipes. Fortunately, minor condensation issues can be reduced substantially with a few inexpensive precautions. Difficulty: Easy.
A chimney installed on the outside wall of a house and serving a basement installation is most susceptible to backdrafting caused by the stack effect. At standby (no fire in the appliance), the air in the flue can cool to outside temperature.With no temperature difference, no draft is produced in the chimney, and the minor negative pressure acting on the air inlets of the appliance can readily cause reverse flow in the chimney.Backdrafting at standby is clear evidence of the stack effect in buildings. chimney installed on the outside wall of a house and serving a basement installation is most susceptible to backdrafting caused by the stack effect.
