The Ravenheat automatic air vent is a pressure protection measure for the central heating unit. It works by using buoyancy to release an accumulation of air. 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.
