Expansion Tanks

Expansion tanks are designed to accommodate water volume changes caused by temperature fluctuations in closed plumbing and hydronic heating systems. By absorbing excess pressure created during thermal expansion, expansion tanks help protect water heaters, boilers, valves, piping, and other system components from premature wear and damage. Available for domestic hot water and hydronic heating applications, expansion tanks support system efficiency, pressure stability, and long-term equipment reliability in residential, commercial, and institutional installations.
