The compact design of the groups minimizes the risk of incorrect installation of the hot water system. The WZS group can be installed with domestic hot water tanks equipped with a dedicated circulation connection, as well as without it. They are equipped with an energy-efficient WILO circulation pump and a thermostatic mixing valve ATM 35\u00f760\u00b0C with a burn protection function.
