What is an Expansion Vessel?

An expansion vessel or expansion tank is used on closed heating and hot water systems to absorb excess pressure and reduce water hammer within the boiler. Expansion vessels are available as a potable vessel or unpotable vessel. Manufacturers Include Zilmet, Cimm, Baxi, Ideal, Worcester and Vaillant.

It is important to take your time to find the right Expansion Vessel for your Gas Boiler. We have a large range in stock at DHS and if you are unsure please give us a call.
