Water Analysis for Heating Water
Incorrect water hardness can lead to issues in the event of a warranty claim. With LILIAN, service technicians can easily determine water quality at the touch of a button.
Key Benefits
Modern heating systems, especially highly efficient systems such as condensing boilers or heat pumps, are increasingly sensitive to the quality of the filling water. Compliance with specific water hardness values in accordance with guidelines such as VDI 2035 is not only crucial for operational safety and energy efficiency, but is also a critical prerequisite for maintaining manufacturer warranties.
Historically, water hardness in heating systems was often neglected, but today, non-compliance with specifications can lead to costly damage and the loss of warranty claims. Heating technicians face the challenge of performing precise measurements, often under difficult conditions, while conventional titration tests are time-consuming, prone to error, and barely legible in dark basements.
The LILIAN system offers an innovative solution to these challenges by revolutionizing water hardness measurement in the heating sector. With LILIAN, technicians can easily and precisely measure the required parameters, such as water hardness, directly on-site at the touch of a button. This eliminates the inaccuracies and hassle of titration tests and delivers immediate, reliable results.
Furthermore, the digital documentation of the measured values creates a seamless and tamper-proof chain of evidence, which is essential for warranty issues or official inspections. By integrating the LILIAN system, heating technicians not only save valuable working time, but also ensure compliance with manufacturer specifications, prevent expensive consequential damage, and strengthen their customers’ trust in the quality of their service.
LILIAN is therefore an indispensable tool for future-proof heating water management.
