Automatic Hydraulic Balancing for Heating Systems
The automatic hydraulic balancing of heating systems is carried out via thermostatic valves and a mathematical algorithm. The aim is to heat up the rooms evenly and to achieve a general temperature stability with changing influencing factors.
TÜV Rheinland checks for heating systems whether the automatic hydraulic balancing works in changing situations within certain maximum deviations.
The test environment is set up in accordance with the technical rules of the VdZ (Forum für Energieeffizienz in der Gebäudetechnik e.V. / Forum for energy efficiency in building technology). Experts from TÜV Rheinland assess whether the automatic hydraulic balancing meets the requirements in this test environment.
This can be done by means of a real test, simulation or emulation, or a combination of both.
In addition to evaluating the results, certification also includes checking and inspecting the test conditions. This includes the inspection of the test setup, the measuring equipment and the software, as well as the suitability of the testing personnel.
Experts analyze and evaluate the heating system. When all the necessary requirements have been met, the heating system is certified. The evaluation and certification is repeated annually or is required if the control algorithm is changed with regard to its function.
For certified heating systems, the test mark may be used in communication.
