Tech Tips
Pumps & Pressurisation > Expansion Vessels
Expansion vessels are water storage tanks which protect heating and hot water systems from excessive pressure, as the system pressure builds as the water is heated. Within a pressure vessel is a rubber diaphragm (membrane) behind which a volume of air is contained, on the other side of the membrane is the system water. As the water heats and expands, the air is compressed, allowing the system pressure to safely increase within risk of burst pipework or appliances.
