Multifunctional sanitary vessels with fixed bladder are designed to be fitted both as expansion tanks into sanitary systems, suitable to absorb the water expansion volume generated by a changing temperature, as well as pressure tanks for cold water sanitary systems.
Both applications are possible thanks to the protective sheath with patented crimping system that ensures the protection against corrosion of the inner surface of the tank.

In your Domestic Hot Water system install Elbi expansion tanks in the cold water supply pipe (do not install in the hot water drawoff pipe).
