Overview
The Sime manual air vent is a pressure safety measure for the central heating unit. They work by using a float to release accumulated air. As water flows through the heating and cooling system, a float within the automatic air vent opens or closes depending on the water level. If the system contains only water, the float will be pushed to the top and the vent will be closed until the water level drops.
