Flue Damper

A flue damper is a device used in space and water heating equipment, specifically in the plumbing, heating, and waste disposal equipment industry. It is designed to regulate the flow of exhaust gases from the heating system through the flue or chimney.

The main purpose of a flue damper is to improve energy efficiency by reducing heat loss through the flue. It does this by closing off the flue when the heating system is not in use, preventing warm air from escaping and cold air from entering the system.

Flue dampers can be manually operated or automated, depending on the specific model and application. Manual dampers are typically controlled by a lever or handle, allowing the user to open or close the flue as needed. Automated dampers, on the other hand, are controlled by a thermostat or other sensing device that detects when the heating system is active and automatically opens or closes the flue accordingly.

In addition to improving energy efficiency, flue dampers also help to maintain proper draft and prevent backdrafting, which is when exhaust gases are drawn back into the living space instead of being safely vented outside. This is particularly important for gas-fired heating systems, as backdrafting can lead to the buildup of carbon monoxide, a dangerous and potentially deadly gas.

Overall, flue dampers play a crucial role in the operation and efficiency of space and water heating equipment, helping to reduce energy consumption and ensure the safe and effective venting of exhaust gases.
