What is the primary role of a flue baffle in a heating system?

The primary role of a flue baffle in a heating system is to slow down excess air as the flue gases pass through the heat exchanger and exit the system. By reducing the velocity of the gases, the baffle increases the contact time between the flue gases and the heat exchanger surfaces. This design enhances heat transfer, allowing the heating system to operate more efficiently and effectively.

The baffle also serves to help manage the temperature of the gases, which can contribute to improved overall performance. In doing so, the flue baffle plays a crucial role in optimizing the combustion process and maintaining the efficiency of the heating system.
