Hydraulic balancing
Directly on the radiator

Hydraulic balancing is a basic requirement for efficient heating systems – and often a stumbling block in practice. A lack of hydraulic balancing leads to uneven heat distribution, over- or under-supply of individual radiators, increased energy consumption and unnecessary costs. The HERZ TS-120-V-SMART Dynamic Thermostatic Valve offers a solution that performs balancing directly and automatically on the radiator – without complex calculations or additional control valves.

Increased efficiency and energy savings are now almost standard topics in the heating industry. But while there is much talk about this, one aspect is often underestimated: hydraulic balancing directly at the radiator. This is exactly where the HERZ TS-120-V-SMART Dynamic Thermostatic Valve comes in – a technical solution that combines simplicity with precision and offers real added value for installers, planners and operators alike.

Two functions, one housing: The technology at a glance

The special feature of this valve is the combination of two functions in one housing: The HERZ TS-120-V-SMART Dynamic Thermostatic Valve combines the functions of a classic thermostatic valve with a differential pressure control valve in one housing. The integrated differential pressure control valve enables the dynamic thermostatic valve to maintain a constant flow rate at the radiator under changing pressure conditions. This ensures that each radiator receives the amount of water it needs. Pressure fluctuations caused by the opening or closing of other radiators in the system are regulated completely automatically. Neither system changes nor system extensions require readjustment or a change in the setting of the dynamic thermostatic valve, which keeps the effort required for hydraulic balancing to a minimum.

Up to 60 kPa: Simple adjustment without additional effort

It is particularly interesting for use in systems with a differential pressure of up to 60 kPa. In this range, the HERZ Dynamic Thermostatic Valve performs the hydraulic balancing completely without additional components. However, it is crucial to combine it with a suitable thermostatic head. This regulates the opening degree depending on the temperature, while the valve itself keeps the flow stable. This ensures that the desired temperature is achieved in every room without the need for time-consuming readjustments by installers. For modernisation and renovation projects, this means a considerable simplification, as the balancing is carried out directly on the radiator and does not have to be planned for the entire system.

For large systems: Differential pressure control valves as an addition

In larger systems, such as residential complexes or commercial properties, where the differential pressure often exceeds 60 kPa or where there are multiple risers, the additional use of differential pressure control valves is essential. These are installed centrally or per pipe and create the necessary conditions for the dynamic thermostatic valves to work optimally. They limit the differential pressure in the system, protect the fittings from overload, and ensure that precise control remains possible even in widely branched networks.

Scalable solution for any project size with HERZ

With the TS-120-V-SMART, HERZ offers a solution that works from single-family homes to large buildings – scalable, practical, and durable. Installers benefit from significantly simplified commissioning, planners from a clearly calculable solution and operators from reliable, efficient heat distribution. Above all, one thing is clear: hydraulic balancing today does not have to be complicated or costly if you use the right components.
