Product Description

An automatic air vent designed for the pump section of Vaillant's Guernsey/Jersey only (condensing), ecoFIT VU (condensing), ecoFIT VUW (condensing), ecoTEC VU (condensing), ecoTEC VUW (condensing), Home (condensing), THERMOcompact VU (fan-assisted), TURBOmax VUW (fan-assisted) and ecoTEC VUI (condensing) boilers. 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.
