Measurement technology for analyzing the heating water

The system can only operate efficiently and smoothly if the heating water has the correct values in accordance with VDI 2035.


The right measurement technology for analyzing the heating water

For proper documentation

Today, measuring devices are a constant companion for heating specialists. VDI 2035 requires certain limit values for the pH value and total hardness of the water in heating systems. Depending on the material composition, the pH value ranges from 8.2 to 10 and the maximum total hardness of the water with low-salt operation < 0.3 °dH. For the required documentation of heating systems, you need correspondingly accurate measurement technology. This allows you to analyze the water and document the measured values in the system logbook.

When filling, topping up and maintaining a heating system for the first time, you should comply with the values required by VDI 2035. Using UWS measurement technology, they analyze data such as pH value, conductivity and magnetite content, through to chloride and iron.

The system separator for protecting the drinking water must also be tested once a year in accordance with DIN EN 806 / DIN EN 1717. The functions to be tested are tightness, start of opening of the relief valve, tightness of the relief valve, venting of the medium pressure zone to atmospheric pressure and the tightness of the outlet-side non-return valve.

You are on the safe side with UWS measurement technology

You can choose between different measurement technology cases. From the “Profi” measuring case to the L-BOXX Premium measuring case and the L-BOXX PST
