High quality automatic air vents for use in heating systems to vent air when commissioning a system. The device consists of a polypropylene float connected to a simple valve. When the build-up of air within the float chamber exceeds a certain level the float drops, opening the valve and releasing the air trapped within the chamber. As the air is released, water replaces it, and moves the float back into the up position, which closes the valve
