Vaillant Pressure Gauges
These gauges monitor and visually display?s the pressure that is present within the boiler. On most Vaillant boilers the pressure gauge is located within the facia at the bottom of the boiler and is an analogue type of gauge with a needle pointing to the pressure. In the newer boilers the gauges are of digital type and can only be seen when a small button is pressed to display the pressure. The digital type pressure gauges are reliant on a pressure transducer that is located within the Vaillant boiler transmitting the information to the gauge via the pcb.
