The Vaillant Automatic Air Vent for Boilers provides additional safety to your central heating unit. Suitable for use with a range of Vaillant boilers (including the ecoTEC Plus range), this air vent uses a float to release built up air. If there is no air in the system, the float rises to the top and shuts the vent until the water level drops, so you can enjoy your boiler free from worry. Vaillant has been breaking new ground in the heating industry since its inception in 1874. They continue to lead the market with renewable technologies and an unparalleled reputation.
