5. INSTALLATION AND INSPECTION OF THE PIPING
5.1. Heating Radiator Water (Water Quality and Related Operations):
Installation water shall be evaluated in the following subjects during the commissioning of the boiler:
1. That the water is suitable for the installation
2.
Operating pressure of the system
3. Flow rate
of the water circulating inside the boilers and the system
5.1.1. Conditioning of the Water: Precautions shall be taken for hardness of water (lime that is
soluble in water) and for particles that form sediments.
Hardness: Lime, which is soluble in water, settles quickly on hot surfaces when water is heated,
and forms an insulating layer and prevents the transfer of heat. As a result, the fins of the
heat exchanger overheat and crack at this point after a while. The water channels in the
sections where condensation takes place are narrow in the fins of the boiler. Therefore, the
boilers are sensitive to calcification (forming of scab).
Calcified boilers are not covered by the warranty.
To prevent calcification, water used in the installations shall be softened. While there are
various methods for this purpose, the most applicable one is to install a resin softening
system to the installation.
