Thermostatic valves for balancing circulation automatically regulate the temperature of circulating water, ensuring even heating throughout the entire hot water distribution system. For example, in the heating circuit of a single boiler room, a so-called "hydraulic separator" is usually installed behind the boiler (or multiple boilers), and without balancing valves, the flow into individual circuits is always higher than the nominal flow. This results in users perceiving insufficient heating as a fault and purchasing an additional boiler.
