What it is

The Altecnic SSV500C is a 500 litre stainless steel expansion vessel intended for use in boiler and heating systems. It accommodates the expansion of system water as it heats, limiting pressure rise within the circuit. This unit forms part of the Altecnic expansion vessel range.

Signs this part needs replacing

  • System pressure climbs quickly as the appliance heats up, then falls again as it cools
  • The pressure relief valve discharges water during normal heating cycles
  • Water appears at the vessel charge valve or the diaphragm has failed
  • The vessel feels heavy or waterlogged when tapped, indicating lost charge
  • The system pressure gauge shows wide or erratic swings

Before you order

  • Confirm the 500 litre capacity is correct for the system volume and expansion requirement
  • Check the connection size and position on the vessel match the existing pipework
  • Verify there is adequate space and structural support for a vessel of this capacity
  • Confirm the required system pressure and pre-charge settings for the installation
