    Expansion Vessels & Ancillaries

    Expansion vessels, also known as expansion tanks, can be found in most domestic pressurised heating systems. If you have a combi boiler, you will have an expansion vessel. This vessel contains air and water from the central heating system, and its purpose is to maintain the right level of pressure in the system.
