What it is

The Altecnic Reflex C Heating Vessel is a 25 litre expansion vessel for sealed heating systems. It absorbs the expansion of heated water, limiting the pressure rise across the system and reducing stress on other components. The part sits within the Altecnic Expansion Vessels range.

Signs this part needs replacing

  • System pressure rises sharply when the boiler heats up and falls again as it cools.
  • Water discharges from the pressure relief valve during heating cycles.
  • The pressure gauge reads high shortly after the system has been topped up and bled.
  • Water or moisture appears at the air valve on the vessel.
  • The vessel does not hold its pre-charge when checked with a pressure gauge.

Before you order

  • Confirm a 25 litre vessel suits the system volume and required expansion.
  • Check the connection size and thread match the existing pipework or mounting bracket.
  • Verify the pre-charge pressure is suitable for the system's cold fill pressure, and adjust if needed.
  • Check the available space and mounting position before ordering.
