The heating systems have become in recent years more compact; smaller heat exchange surfaces can offer today much higher performance than before. This makes them however more subject to malfunction. If the heating system operates with inadequate water quality the consequences are: corrosion, lime deposits, sludge and air in the system.
For this reason heating systems are to be filled and shall work with soft water, according to the VDI 2035 regulations.
Thanks to a mixture of selected ion exchange resins and a pH stabilizer in the first filling operation, the water is largely demineralized (>0,5°dH) and alkalized to pH values between 8.2 to 8.7.
As the corrosive ions, such as chloride and sulfate, are also removed, a better protection against corrosion is provided without the help of chemical inhibitors. At the same time water conductivity is reduced.
