The Chaffoteaux automatic air vent is a safety mechanism built into the central heating unit. They work by releasing accumulated air using buoyancy. As water circulates through the heating and cooling system, a float within the automatic air vent opens or closes depending on the water level. If the system is full of water, the float will be pushed to the top and the vent will be closed until the water level drops.
