Worcester Greenstar Expansion Vessel 10L – Refurbished | Part No. 87154072960

In a sealed central heating system, pressure control is everything. When the expansion vessel fails, water expansion during heating has nowhere to go — the pressure relief valve trips, the boiler loses pressure, and callouts become a recurring cost. The Worcester Greenstar Expansion Vessel 10L (Part No. 87154072960 / 8716122434) is the correct OEM-specification replacement for the Greenstar CDi range, designed to absorb thermal expansion efficiently and keep your system pressure steady across every heating cycle.

This is a professionally refurbished genuine Worcester Bosch component. Each unit is stripped, cleaned, and pressure-tested against OEM specifications before dispatch — delivering manufacturer-grade performance at a significantly lower cost than a new part. The updated part number is 8716122434; orders will be fulfilled with this superseding part. The 10-litre capacity provides a direct like-for-like fit with no modifications required.
