2.4.6 Requirements for the heating water
Observe the current technological regulations to
prevent corrosion products and deposits.
Minimum requirements regarding the quality
of filling and supplementary water:
– Water hardness (calcium and magnesium,
calculated as calcium carbonate):
3 mmol/l
– Conductivity: 1500 (ideal 100) ȝS/cm
– Chloride: 250 mg/l
– Sulphate: 250 mg/l
– pH value (heating water): 6,5 - 8,5
Using filling water and top-up water which does
not meet the stated quality requirements can
cause a considerably reduced service life of the
equipment. The responsibility for this is entirely
that of the operator.
