What it is

The Hamworthy 532712072 is an 8 litre expansion vessel used in Hamworthy heating appliances. It absorbs the volume increase of water as the system heats, limiting pressure rise within the sealed circuit. The part carries the manufacturer reference ZI-306008W.

Signs this part needs replacing

  • System pressure climbs sharply once the appliance is running and heating the water.
  • The pressure relief valve discharges water during normal heating cycles.
  • Boiler pressure falls repeatedly and needs frequent manual topping up.
  • Water, rather than air, is released when the vessel charge valve is depressed.
  • The vessel feels heavy or waterlogged when compared with an empty unit of the same size.

Before you order

  • Confirm the appliance model against the manufacturer's parts list to verify this part number applies.
  • Check the existing vessel's stated capacity and reference markings match 8 litres and ZI-306008W.
  • Verify the system has been depressurised and drained before removal of the old vessel.
  • Check the vessel connection and mounting arrangement suit the installation before ordering.
