Altecnic Reflex 250 Litre Heating Expansion Vessel HV250W

The Reflex 250 litre Heating Expansion Vessel is manufactured by Altecnic for use in sealed heating systems. It takes up the increased volume of water as the system heats, limiting the pressure rise and reducing stress on other components. The vessel forms part of the Altecnic expansion vessel range used on boiler installations.

• System pressure climbs sharply once the boiler heats up, or the pressure relief valve discharges water.
• The pressure gauge swings widely between hot and cold readings, or the boiler locks out on low pressure.
• The vessel feels heavy or sounds full of water when tapped, indicating the internal diaphragm has failed.
• Water escapes from the air valve when the charge pressure is checked.

• Confirm the vessel capacity suits the system volume and the manufacturer's sizing guidance.
• Check the pre-charge pressure required for the installation before fitting.
• Check the connection size, position and orientation against the existing vessel and pipework.
• Confirm there is sufficient space and support for the vessel at the intended location.
