HERZ thermostatic valves look after the environment and the budget for heating costs. One can throw money out of the window or one can reduce the energy consumption of the heating system thanks to the precise Herz regulation. HERZ thermostatic valves regulate the room temperature, depending on the environmental temperature whilst taking external thermal influences into account, without requiring any additional external energy. The highly sensitive HERZ hydrosensor reacts to the smallest change in temperature, long before you can perceive it yourself. Precise regulation reduces the energy consumption of every hot water heating system.
