NOTE
●
For detailed information refer, among
other things, to the VDI Guidelines
2035 “Vermeidung von Schäden in
Warmwasserheizanlagen” (preventing
damage in hot water heating systems).
●
Required pH value: 8.2 … 10
●
for aluminium materials:
pH value: 8.2 … 8.5
►
Fill the system with deionised heating water
(VE water) or with water corresponding to VDI
2035 only (low-salt operation of the system).
Advantages of low-salt operation:
●
Low corrosion-promoting properties
●
No formation of mineral scale
●
Ideal for closed heating circuits
