OFFICIAL Grant Expansion Vessel 16Ltr – VBS38

Genuine Expansion Vessel for Grant Vortex 36/46 Boilers

The Grant VBS38 Expansion Vessel (16 Litre) is a genuine OEM part designed specifically for Grant Vortex 36/46 oil-fired boilers. This essential component absorbs excess pressure caused by heated water expansion in sealed central heating systems, helping to maintain safe and consistent boiler performance.

If your system is losing pressure or showing signs of over-pressurisation, the expansion vessel may be at fault. Replacing it with the VBS38 ensures your boiler remains efficient, protected, and compliant with system safety standards.
