Worcester Bosch Expansion Vessels

Worcester Bosch Expansion Vessels also sometimes called expansion tanks or pressure vessels are a component fitted internally to Worcester Bosch Combi type and sealed system boilers and it's function is to compensate for the expansion of hot water, as water will expand when heated producing a rise in pressure within the sealed or closed system. There is a menbrane or diaphragm within the vessel which separates the water from the air and this allows the water to expand. All our Worcester Bosch Expansion Vessels are new and genuine manufacturer spares.
