Abstract: At present, storage-type electric water heaters have a large quantity in urban households in our country. Maintenance, component life, and corrosion resistance of the inner tank and heater will affect the service life of the water heater. Corrosion of the inner tank may cause water leakage, electric leakage, and explosion. Such problems endanger the personal and property safety of users. Compares the application of anti-corrosion measures such as heating tube anti-corrosion, magnesium rod anode and electronic anode in water storage electric water heaters, regard electronic anode as future development direction.

Key words: Storage water electric heater, Electronic anode, Magnesium anode, Corrosion protection
