Unsuitable quality of the fill and make-up
water in the heating circuit
The efficiency of the system and the life of the heat
generator and the heating components depend
decisively on the quality of the heating water.
If the system is filled with untreated domestic water,
calcium precipitates as scale. Limescale deposits
form on the heat transfer surfaces of the heating. The
efficiency drops and energy costs rise. In extreme
cases the heat exchangers are damaged.
►
Fill the system with deionised heating water
(VE water) or with water corresponding to VDI
2035 only (low-salt operation of the system).
Unsuitable quality of the water-antifreeze
mixture in the heat source
►
Use of pure water in the heat source is not permit-
ted
►
For operation of the heat source with a water-
antifreeze mixture, ensure that the water used
fulfils the quality specifications of the heating
water side.
