At Buildworld, we stock all the accessories and products that are needed for building hot water systems as well as maintaining or upgrading them. These include components such as storage tanks, boilers, valves and expansion vessels.
Expansion vessel also called as the Expansion tank is a container that features a rubber diaphragm in the centre and has air filled on one side of the diaphragm and water on the other. Usually made of steel, the vessel is impermeable to external elements and stands up to any hydraulic shock. The Expansion tank helps any closed water heating system combat an increase in pressure, usually caused by heated water. Their steel body and internal rubber diaphragm allows them to withstand thermal expansion and constant water hammer, thereby keeping the system running efficiently.
