Controlling hydraulics –
Making building services engineering efficient


Heating and cooling systems are not only complex systems in building services - they also have great potential: if they are optimally adjusted, they sustainably improve the energy efficiency of the building. A heating system with Oventrop thermostatic valves and balancing and pipeline valves as well as hydronic balancing can save up to 20 % energy. But not only that - if a hydronic system reliably controlled, this also increases comfort: the desired room temperature is reached and maintained quickly and precisely. With our modular hydronic solutions, you can turn the entire building services into an efficient, reliable and flexible system:

These are the modular Oventrop solutions:

Hydronic balancing in heating and cooling systems

Connections and components for fan coil kits

The Uni L thermostat impresses with its simple and timeless design. Handling and readability are optimally matched. The radiator thermostat is equipped with a memo disc to mark a selected setting, which makes it easy to reset a desired temperature after turning the handwheel. 
The setting range can be limited or blocked using the two concealed internal limiting elements. In case of unfavourable lighting conditions or for visually impaired persons, the basic setting “3” can easily be found again by using the palpable setting aids.

Connection and control of heating and cooling devices

Differential pressure measurement and verification of water quantities

Shutoff valves and other pipeline valves

The key factor in building services engineering.

Why is a functioning hydronic system so important for building services engineering? Hydraulics deals with the flow behaviour of fluids. In heating systems, the heat and kinetic energy of water or other fluids is used for energy transfer. From the hydronic point of view, the entire system can be divided into several areas: the heat generation, the distribution system and the heating surfaces themselves. If the hydraulics is not optimally adjusted, this becomes noticeable - especially during the heat-up phase after a break in operation or night setback. Then, for example, these problems can arise:

  • The rooms do not get warm at the same time.
  • The heating gurgles.
  • Radiators do not get warm at all or only partially.
  • Other radiators get too hot.
  • The energy consumption is too high.

The solution:
hydronic balancing

With hydronic balancing, the water is optimally distributed in the entire system. Pressure and volume flows are regulated and all components such as radiators, thermostatic valves, balancing and pipeline valves, pumps and pipes are coordinated and balanced with each other. The result is an optimally adjusted hydronic system: all radiators and other consumers are sufficiently supplied and there are no performance fluctuations in the heating system.

At Oventrop we have the expertise, the pioneering products and the modular service to control hydronic balancing simply, efficiently and reliably.
