Entlüftungsventil De Dietrich S101770

An air vent is a simple but vital boiler spare part that automatically releases trapped air from the heating system. Air pockets can cause noisy operation, reduced efficiency, and uneven heating. This component typically uses a float mechanism to vent air while preventing water loss. Installing or replacing an air vent helps maintain proper circulation and protects the system from air-related issues, contributing to reliable boiler maintenance.
