What is the purpose of a flue pipe in an oil heating system?

The purpose of a flue pipe in an oil heating system is to vent combustion gases safely outside. When oil is burned in the heating system, it produces gases such as carbon dioxide, water vapor, and potentially harmful pollutants. The flue pipe serves as a pathway for these gases to exit the heating unit and go outdoors, ensuring that they do not enter the living space where they could pose health risks to occupants.

By directing these gases outside, the flue pipe helps maintain indoor air quality and provides proper airflow for the combustion process, which is critical for the heater's efficiency and safety. Moreover, having a well-functioning flue system is vital to prevent the buildup of toxic gases, such as carbon monoxide, which can result from incomplete combustion or blockages in the venting system. Thus, the flue pipe is essential for both the safety and the effective operation of an oil heating system.
