An air vent is a simple but important device used to release trapped air from heating systems, such as boilers, radiators, and pipes. Air pockets can cause circulation problems, noise, and reduced efficiency. Automatic air vents continuously purge air without manual intervention, while manual vents require periodic bleeding. This component is typically installed at high points in the system. Regular maintenance or replacement of a faulty air vent helps prevent corrosion and ensures smooth operation of the heating circuit.
