What it is

The Vokera 8 litre expansion vessel (part number 1830) is supplied with a pipe for connection to the boiler. It is fitted to Vokera Linea 24 and Linea 28 appliances, where it absorbs the expansion of water as the heating system heats up and helps hold system pressure steady.

Signs this part needs replacing

  • System pressure rises sharply when the boiler heats up and drops again as it cools.
  • The pressure relief valve discharges water during normal heating cycles.
  • The boiler loses pressure and needs frequent topping up.
  • Water or corrosion is present at the vessel connection or air valve.
  • The vessel feels heavy, or water is heard inside it when the system is drained.

Before you order

  • Confirm the boiler model and serial number against the Mk1 and Mk2 changeover points listed above.
  • Check the vessel capacity and connection arrangement match the part being removed.
  • Check the system pressure and the expansion vessel charge pressure before fitting.
