Altecnic Reflex C Heating Vessel 80 Litre HV80I

The Reflex C Heating Vessel from Altecnic is an expansion vessel with a nominal capacity of 80 litres, intended for sealed heating and central heating systems. It absorbs the increase in water volume as the system heats up, limiting pressure rise and protecting components such as the pressure relief valve. It forms part of the Altecnic expansion vessel range.

• System pressure rises sharply once the boiler fires and the water heats up.
• Water discharges from the pressure relief valve during normal heating cycles.
• System pressure drops repeatedly and needs frequent top-ups.
• Water, rather than air, is present at the vessel's air charging valve.
• The vessel feels full or heavy when tapped, indicating a failed internal diaphragm.

• Confirm 80 litres is the correct nominal capacity for the system volume and pressure.
• Check the vessel's connection size and thread match the existing pipework.
• Verify the available space and mounting arrangement suit the vessel's dimensions.
• Confirm a heating vessel is required rather than a potable water vessel.
