What it is

The Vaillant 0020236148 is a pressure gauge used on Vaillant unvented hot water cylinders. It provides a visual indication of system pressure at the cylinder so the reading can be checked during servicing and commissioning. It is listed for the VIH GB and Vantage VIH GB cylinder families.

Signs this part needs replacing

  • The needle sits at zero or does not move when the cylinder is pressurised
  • The reading is visibly inconsistent with the pressure shown elsewhere on the system
  • The dial face is fogged, discoloured or holds condensation
  • The lens is cracked or the body shows signs of leakage
  • The needle sticks or jumps rather than moving smoothly

Before you order

  • Confirm the model and variant from the cylinder data plate, as fitment differs across the VIH GB range
  • Check the existing gauge against the part number 0020236148 before ordering
  • Confirm whether the gauge is supplied as part of a larger assembly on your cylinder
  • Isolate and depressurise the cylinder before removing or refitting any gauge
