Water Heater Anode

Electrical water heater may leak water and electricity after using for a while, this is mostly for the reason that the magnesium rod is consumed but not replaced in time, the water heater tank become corrosion and perforation. In general, electric water heaters magnesium rod must be replaced every two years or less. Because of the water quality differences, some water heater may run out of use less than one year. Short life span, frequent replacement makes the cost increase. The principle reason of water heater tank corrosion is Cl- corrosion in water. The water quality all over China is different and it is difficult to find an efficient protection method.

The Mixed Metal Oxide (MMO) titanium electrode provided by Elade as auxiliary anode, water heater works as cathode, they forms a protection system in the water of water heater which also service as conducting medium. When electricity pass through electrode, the Cl- in water moves towards anode and concentrate there, the Cl- in the cathode side will become dilution. The water heater tank as cathode in reductive environment, this can shorten the corrosion speed of tank and expand its life span.

Compare with traditional magnesium anode rod, this MMO water heater anode is of these advantages: 

Longer operating life: 5-20 years, while magnesium anode is about 2 years; 

Light weight than magnesium anode; 

Solving the rotten-egg odor, while sacrificial anode can not; 

Easy to maintain than  magnesium anode.
