What it is

The Grant VBS06 is a 12 litre flat expansion vessel for Grant Vortex Pro condensing oil boilers. It absorbs the expansion of water as the system heats up, helping to maintain stable pressure and protect components such as the pressure relief valve. This flat-profile vessel is listed for 26-36kW Vortex Pro models.

Signs this part needs replacing

  • Boiler pressure rises quickly when the heating is on
  • Pressure relief valve discharges water, often visible from the discharge pipe
  • Pressure gauge reads high or fluctuates without obvious cause
  • Water or corrosion visible around the expansion vessel connection
  • Boiler locks out or loses pressure repeatedly

Before you order

  • Confirm your boiler is a Grant Vortex Pro 26-36kW condensing model
  • Check the existing vessel is a 12 litre flat type and note the part number VBS06
  • Ensure the system is fully depressurised before removal
  • Verify the vessel connection and mounting arrangement match the existing part
