Put the heating tube in a pot or kettle, fill it with water, add a little baking soda, and boil it. After a few minutes, the
scale will automatically fall off. Cleaning the heating tube with clean water multiple times will completely clean it.

Various chemical anti-sealants, such as chelates, phosphates or phosphonates (organophosphates),
polycarbonates, and components of polymers, have been developed to inhibit or reduce the formation of inorganic
scales.
Result: Thus, service & repair geyser, demonstrate replacing heating element of geyser, locate the faults in
geyser and solve faults has been completed successfully.
