Maintenance
To extend its service life and ensure that the water heater always works very eiciently,
professionals can maintain the electric water heater in the following ways:
1. Clean the heating elements regularly (depending on local water quality) and remove
limescale deposits stuck to the heating elements; In areas with a lot of limescale,
users can install anti-limescale equipment at the front of the inlet (cooling) pipe
themselves.
2. Check the magnesium rod installed on the heating element regularly (depending on
local water quality). Replace it in time when it is exhausted.
