What it is

The 35 litre Stainless Steel Expansion Vessel is manufactured by Altecnic and forms part of the Altecnic expansion vessel range for sealed heating systems. It accommodates the expansion of system water as it heats, limiting the associated pressure rise. The vessel is constructed in stainless steel with a 35 litre nominal capacity.

Signs this part needs replacing

  • System pressure rises sharply once the boiler is running and heating the water
  • The pressure relief valve discharges during normal operation
  • Water is heard inside the vessel, or the shell feels heavy when tapped
  • System pressure falls repeatedly and needs frequent topping up
  • Corrosion, weeping or staining is visible at the vessel shell or its connection

Before you order

  • Confirm that a 35 litre capacity suits the system volume and design pressure
  • Check the connection size and thread against the pipework it will serve
  • Verify the available space and the mounting arrangement at the installation point
  • Confirm the vessel is intended for the Altecnic expansion vessel installation being worked on
