What it is
The Reflex 600 litre Heating Expansion Vessel is a sealed-system expansion vessel manufactured by Altecnic. It is part of the Reflex range and is used on heating installations to absorb the increased volume of water as the system heats up, helping to keep system pressure stable.
Signs this part needs replacing
- System pressure rises sharply when the appliance heats up and drops again as it cools.
- The pressure relief valve discharges water during normal heating cycles.
- The system needs frequent topping up to maintain pressure.
- Water is present at the vessel connection or the vessel body shows corrosion or damage.
- The vessel feels full of water and no longer responds to system pressure changes.
Before you order
- Confirm the required vessel capacity for the system volume and the pressure it will operate at.
- Check the connection size and thread on the existing vessel match the pipework it will serve.
- Verify there is sufficient space and structural support for a vessel of this size.
- Check the pre-charge pressure setting required for the installation.
