Altecnic Reflex C Heating Vessel 35 Litre HV35I

The Reflex C Heating Vessel is a 35 litre expansion vessel manufactured by Altecnic. It forms part of the Reflex C range of vessels used in sealed heating systems, where it accommodates the expansion of system water as it heats. The vessel connects into the heating circuit and maintains system pressure within its operating range.

• System pressure rises sharply when the appliance heats up and falls again once it cools
• Water discharges from the pressure relief valve during normal heating cycles
• The vessel feels heavy or water is heard inside it when the system is drained down
• Repeated topping up of system pressure is needed to keep the boiler running
• Visible corrosion, weeping or damage at the vessel connection or shell

• Confirm the required vessel capacity against the system volume and the appliance manufacturer's requirements
• Check the vessel connection size and orientation against the existing installation
• Verify the system's cold fill pressure and that the vessel's pre-charge suits it
• Confirm there is sufficient space to fit and service the vessel
