This air vent is for use in the pump section of Worcester Bosch's Greenstar, RD Series, Novatherm and Greenstar ErP boiler range. A central heating safety device, the air vent releases built up air. As water flows through the system, a float opens or closes the vent depending on the water level. When the system is full the float is pushed to the top, closing the vent until the water level drops. As the leading supplier of parts for all the major boiler manufacturers we’ve got a wealth of experience and knowledge in this area, and with over 450 branches we carry more heating spare parts in more places than any other merchant to help you improve your first time fix rate.
