7.2 Heating water quality

NOTE
● For detailed information refer, among
other things, to the VDI Guidelines

Warmwasserheizanlagen"
damage in hot water heating systems).
● Required pH value: 8,2 ... 10
● for aluminium
8,2 ... 8.5
► Fill the system with deionised heating water
(VE water) 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
● ideal pH value due to self-alkalinisation after
filling the system
● If necessary, simple alkalinisation to pH value
8.2 by adding chemicals
7.3 Fill, flush and vent heat source
Water and the following antifreeze products are
approved for filling the brine circuit:
● Monopropylene glycol
● Monoethylene glycol
● Ethanol
● Methanol
► For operation of the heat source with water or
water-antifreeze mixture, ensure that the water
fulfils the quality specifications of the heating
water side.
► Check that frost protection to –13 °C is ensured.
► Ensure that the antifreeze is compatible with the
pipe, seal and other component materials used
on site.
Drain pipe of the safety valve is connected.
