Heating Engineering

Data-based heating water monitoring system

The project developed a data-based tool for monitoring the state of heating water. The software module can identify harmful physical and chemical processes at an early stage and can thus prevent corrosion and a decrease in heat transfer.


Hot water plays a key role in increasing the energy efficiency of central heating systems. The components used in modern heating systems are sensitive to changes in heating water due to chemical and physical processes (changes in pH-value and in conductivity), in a way that can cause corrosion and a decrease in heat transfer. Monitoring can help identify the harmful processes at an early stage and can aid in maintaining the efficiency of the heating systems. The objective of the research project was to develop a data-based tool to monitor and document the state of heating water. For this purpose a, software module was developed whose specifications were developed together with boiler manufacturers, installers for heating systems, the DIN-committee (German Institute of Standardization), and manufacturers of measurement technologies. The operational reliability of the software module was verified by test runs.


  • The data for the interface (analysis results, technical specifications) can be anonymously combined, and can be utilised and processed across the companies. 
  • Regional problems in heating systems, whose cause may be, for example, the feed water supplied from the local water supplier, can be detected.
  • The analysed results from an external laboratory can also be imported in the database.
  • The graphic representation of parameters in the statistic module of the software packet makes the visualization of changes in replenished and heating water possible.
