What it is

High pressure valve, part number 7824810, manufactured by Viessmann. It is a pressure relief and safety component used on Vitodens WB1A Combi 30KW gas boilers, where it discharges excess pressure from the heating circuit. The part sits in the gas boiler spares range for this appliance family.

Signs this part needs replacing

  • System pressure reads high on the boiler gauge and does not settle after bleeding.
  • Water discharges continuously from the pressure relief discharge pipe.
  • The valve weeps or drips when the system is at normal operating pressure.
  • The boiler locks out or shuts down on overheat or high pressure faults.
  • Scale or debris is visible at the valve outlet.

Before you order

  • Confirm the appliance is a Vitodens WB1A Combi 30KW or Combi PLUS 30KW.
  • Check the appliance serial number against the fitment list, particularly where the date reference applies.
  • Compare the part number on the existing valve with 7824810.
  • Confirm whether the boiler is the Combi or Combi PLUS variant.
