What it is

The Vokera 10024662 is an expansion vessel used in Vokera RAIN series gas boilers. It absorbs the volume change of water as the system heats and cools, holding system pressure within the range the boiler is designed to operate at. It is a serviceable component within the boiler's sealed water circuit.

Signs this part needs replacing

  • System pressure rises quickly when the boiler heats up and falls again once it cools
  • Pressure relief valve discharges during normal heating cycles
  • Boiler locks out or shuts down on low water pressure shortly after filling
  • Water present at the vessel's air valve, or the valve will not hold charge
  • Visible corrosion, pitting or deformation on the vessel body

Before you order

  • Confirm the boiler model against the fitment list above, as RAIN variants differ
  • Check the existing vessel's part number or label where it is still legible
  • Verify the system has been correctly charged and that pressure loss is not caused by a separate leak
  • Confirm access for removal and refitting, as the vessel is often mounted at the rear of the appliance
