What is a fireplace damper?

A fireplace damper is a movable metal or ceramic flap located above the firebox in a fireplace chimney. Its purpose is to regulate airflow, controlling the amount of oxygen that reaches the fire and helping to maintain a consistent burn.

The damper can be opened or closed manually using a lever or pull chain, or in more modern fireplaces, with a remote control. When the damper is fully open, it allows for maximum airflow, which is useful for getting a fire started or keeping it burning strongly. When the damper is closed, it restricts airflow, helping to control the intensity of the fire and reducing the amount of warm air that escapes up the chimney.

A properly functioning damper is essential for the efficient operation of a fireplace, as it helps to prevent heat loss and ensures that smoke is properly vented out of the home. Damper maintenance is important to keep it functioning properly, including regular cleaning and inspection to remove any buildup of soot or debris that could affect its operation.
