Damper systems in chimneys are crucial for regulating airflow and optimizing the performance of heating appliances. These systems can be installed in the breeching or at the chimney's top, where they manage the amount of air that flows through the chimney. By controlling this airflow, dampers help enhance combustion efficiency, reduce heat loss, and prevent drafts. They are operated either manually or by electric-driven motors, allowing for precise adjustments to suit various heating needs. Properly functioning dampers not only improve energy efficiency but also contribute to overall safety.
