The buffer tanks operate analogously to stratification tanks. In other words, they act like a heat battery, decoupling heat generation from heat consumption both in time and hydraulically.
This is an essential prerequisite for the supply of energy from waste heat, solar systems, CHP and other heat generators, the thermal emission of which is not directly oriented to matching demand. Buffer tanks cover an extremely variable application area; essentially, they are used as a primary store for supplying heating systems.
