HEATER CLEANING AND ANODE ROD EXCHANGE
Repetitive
water heating causes limestone sediment on both the enamelled tank walls and chiefly the
flange lid. The sedimentation depends on the hardness of water heated, its temperature, and amount of
hot water consumed.
We recommend checking and cleaning the tank from scale and eventual replacement of
the anode rod after two years of operation.
T
he anode life is theoretically calculated for two years of operation; however, it changes with water
hardness and chemical composition in the place of use.
Based on such an inspection, the next term of
anode rod exchange may be determined.
Have the company in charge of service affairs clean and exchange
the anode.
When discharging water from the heater, the mixing valve of the hot water tap must be open in
order to avoid creating underpressure that would prevent water discharge.
To prevent formation of bacteria (e.g. Legionella pneumophila) within stack heating it is
recommended, if absolutely necessary, to increase the temperature of HSW periodically
for a transitional period of time to at least 70°C. It is also possible to make use of another
way of HSW disinfecting.
