Imagine you’re sitting at the customer’s kitchen table. The new building is almost finished, the heat pump is gleaming in the boiler room – and the manufacturer’s documents are lying on the table. Suddenly, the big question arises: “Do we now have to follow the VDI 2035 or the ÖNORM?” And you think: “So, which […]
During installation, filling, and maintenance of heating systems, standards such as VDI 2035, ÖNORM H 5195-1, and SWKI BT 102-01 are of central importance. Heating water comes into contact with almost all components of the system and can cause significant damage – from oxygen ingress to sludge and lime deposits, up to corrosion. Proper treatment […]
Measurement accuracy. Standard safety. Operational guarantee. For HVAC professionals, accurate heating water analysis is essential: VDI 2035, ÖNORM H 5195-1, and SWKI BT 102-01 set clear requirements for pH value, conductivity, and other parameters such as oxygen.
