5.2.5
Filling the heating system with water
Water hardness must correspond to CSN 07 7401 and it is essential, in case the water hardness does not comply, treat water in
accordance with the Chap. 4.1.
Heating systems with the open expansion tank allow direct contact of the heating water with atmosphere. During the heating season
the water expanding in the tank absorbs oxygen, which increases the corrosive effects while there is a considerable evaporation of
water. To refill, only water treated according to CSN 07 7401 may be used.
The heating system must be thoroughly flushed in order to wash out all impurities.
During the heating season it is necessary to keep a constant volume of water in the heating system. When refilling the heating system with
water it must be ensured that no air is sucked into the system. Water from the boiler and the heating system must never be discharged or taken
for usage except for the emergency cases like repairs etc. Water discharge and filling with new water increases the danger of corrosion and
scale development. If it is necessary to refill water in the heating system, refill water only into the cold boiler in order to prevent
cracking of the sections.
After filling the boiler and the heating system, all connections tightness should be checked.
When using the two-way safety valve DBV 1 - 02, the cooling water is refilled gradually into the return water.
The assembly completion and heating test execution must be recorded in the "Warranty card".
