4.3.7 Boiler Water Specifications
Properties that should be in boiler water; EN 12953-10 “ Shell boilers- Part 10:
Requirements for feedwater and boiler water quality ” must comply with the
standard. In the boiler and heating system, water in quality of drink water
should be used in order to prevent damage caused by corrosion. Aggressive
water should not be used for chemical additives because of corrosion. The
water content to be filled in the boiler and the installation must not contain
residues, dirt and undesirable solid particles. These deposits and dirt are
extremely harmful to the circulation pump. If you are suspected that the water
is not clean, necessary precautions should be taken.
Calcified water used in the system forms a lime and mud layer on the heating
surfaces of the boiler. This lime and mud layer prevents water circulation and
heat transfer and deforms the boiler. This is not covered by the warranty.
