The Worcester 87154072460 Expansion Vessel is a genuine replacement central heating pressure-management component designed to absorb the natural expansion of water as it heats up within your system. As the boiler warms water, its volume increases; the expansion vessel accommodates this rise in pressure, preventing stress on pipework, seals, pumps and valves. A correctly functioning expansion vessel helps reduce the frequency of low-pressure faults, supports consistent heat distribution and contributes to smoother, quieter boiler operation.

This 10-litre expansion vessel is compatible with Worcester and Worcester Bosch boilers that specify part number 87154072460 in their technical documentation. To ensure correct fitment and dependable performance, always verify that the part number matches your existing vessel or consult your boiler’s service information before installation, as vessel sizes and capacities vary between models and system configurations.

Supplied ready for direct replacement, the 87154072460 Expansion Vessel connects to the boiler’s internal pressure line and mounting point when installed by a qualified engineer. Choosing this genuine Worcester Bosch component helps restore proper pressure balance, supports efficient heat delivery and contributes to reliable, trouble-free heating and hot-water performance in compatible heating systems.
