What it is

The Altecnic 100 litre Stainless Steel Expansion Vessel is a diaphragm expansion vessel from Altecnic, supplied with the product reference SSV100C. It is used within Altecnic expansion vessel arrangements on boiler and heating systems, absorbing the expansion of heated water to keep system pressure stable.

Signs this part needs replacing

  • System pressure rises sharply when the appliance heats up and falls again once it cools.
  • Water is discharged from the pressure relief valve during normal operation.
  • The vessel feels heavy or full of water when tapped, indicating a failed diaphragm.
  • Visible corrosion, pitting or damp patches on the vessel shell or its connections.
  • Frequent top-up of system pressure that does not hold.

Before you order

  • Confirm the existing vessel is 100 litres so the system expansion volume is matched.
  • Check the vessel fits the available space and that its connections suit the pipework arrangement.
  • Verify the system type and pressure range are suitable for the installation before fitting.
  • Inspect the mounting arrangement and the condition of the connecting pipework and relief valve.
