What it is
The Reflex 500 litre Heating Expansion Vessel is a sealed expansion vessel for heating systems, manufactured by Altecnic. It absorbs the volume increase of system water as it heats, limiting pressure rise and protecting the boiler and system components. The vessel is categorised for boiler and heating applications and is supplied under part number HV500W.
Signs this part needs replacing
- System pressure falls repeatedly and needs frequent topping up
- Water discharges from the pressure relief valve as the system heats
- Water, rather than air, escapes when the air charge valve is depressed
- The vessel feels heavy and water-filled when tapped
- Boiler pressure rises sharply when hot and drops when cold
Before you order
- Confirm that a 500 litre vessel is correctly sized for the system volume and heat output
- Check the pre-charge pressure and maximum working pressure on the vessel data plate against the system design
- Verify the connection size, orientation and mounting arrangement match the existing installation
- Check there is sufficient space, access and structural support for the vessel and its pipework
