What it is
The VBS124 is Grant's 24 litre expansion vessel for Vortex Pro combi boilers. It is a sealed, air-charged vessel that absorbs the increase in water volume as the heating system warms, protecting the system from excess pressure.
Signs this part needs replacing
- The pressure relief valve discharges regularly, or system pressure creeps up when the boiler is heating
- The vessel feels waterlogged (heavy, or water at the Schrader valve) rather than air-filled
- The pressure gauge fluctuates more than expected during heating cycles
- Visible corrosion, dents, or a failed weld/seam
Before you order
- Check the vessel's pre-charge pressure before assuming it needs replacing — a re-pressurised vessel may solve the fault
- Isolate and depressurise the heating system before removing the vessel
- Check the expansion vessel pressure annually as part of the boiler service
