Expansion Vessels

At Plumb Center, we stock a wide range of boiler expansion vessels, ranging in size and shape to accommodate all styles of boiler.

Expansion vessels are designed to protect domestic hot water boilers and closed water heating systems from excessive pressure. They allow water to be stored within the vessel while also leaving room to store air, which prevents the water pressure from reaching its maximum limit while also maintaining sufficient levels of pressure when water levels are lower.

Our boiler expansion vessels range from smaller models at around 4L, to much larger vessels at 25L. All of our portable expansion vessels ensure that the water is fully drinkable.

We stock central heating expansion vessels from Altecnic, Flamco and our own brand, Center.
