What it is
The Reflex 8 litre Heating Expansion Vessel is manufactured by Altecnic and forms part of the Reflex range of expansion vessels used on heating systems. It provides the expansion space needed as water heats and increases in volume, helping to keep system pressure stable and within the operating limits of the installation. The vessel carries the part number HV8C.
Signs this part needs replacing
- System pressure climbs quickly once the boiler fires and heating begins
- The pressure relief valve discharges during normal heating cycles
- Water is found at the air valve when the valve core is depressed, indicating a failed internal diaphragm
- Frequent manual top-ups are needed to hold system pressure
- System pressure swings widely between cold and hot states, or the vessel feels heavy or full when tapped
Before you order
- Confirm an 8 litre vessel suits the system volume requirement and matches the existing vessel's capacity
- Check the connection size and orientation against the existing installation
- Verify there is sufficient clearance for the vessel at the mounting point
- Consider the pre-charge pressure the system requires before fitting
