The role of magnesium rods placed in water heaters is to absorb ions present in the water heater water and protect the water heater's inner tank and heating tube. In water heaters, magnesium rods are installed in the middle of the metal cladding. When the enamel coating on the surface of the metal coating is intact, the enamel protects the metal coating, the insulation resistance between the magnesium rod and the metal coating can reach more than 2MΩ, and the output current of the The magnesium anode (rod) is almost zero.
When a local crack occurs in the enamel coating, a small resistance is formed between the magnesium anode and the metal coating through the water, and the magnesium anode begins to produce current, which flows to the exposed metal coating to produce a polarized film, repairs damaged enamel, isolates the coating from the gold domain toavoid corrosion.

Precautions when using water heaters:
1. The water used contains impurities and various metallic substances. Long-term use will cause oxidation reactions and. corrosion of internal components. The coating is the heart of the electric water heater. Once the coating is corroded or damaged, water will leak out. It is difficult to repair and the only option is to replace it.
2. The cost of replacing a new liner is the same as purchasing a new water heater. Magnesium rods placed in the water heater will absorb ions present in the water and protect the liner and heating tubes.
3. Depending on water quality, the magnesium rod in the enameled water heater should be replaced every one to two years. Otherwise, once the stemWhen magnesium is exhausted, the water heater will quickly corrode and leak.
4. The cost of replacing the magnesium rod should also be noted. The replacement of the magnesium rod is free during the warranty period, but after the warranty period, you need to pay the material charges.

< p>It's free.
But it should be noted that if the magnesium heating rod is broken, there is actually no replacement cost if it is not broken, but the heating effect is not good Due to scale buildup, this situation is not considered a machine breakdown and is not included. It is covered by warranty, so it is not free.
At the same time, the guarantee will not be provided in the following situations:
1 Impossibility of producing theVoucher of the Three Guarantees;
2. Three warranty vouchers (including invoice) ) The model does not match the model of the repaired product or has been modified
3. Consumers cause losses due to misuse, poor maintenance and storage;
4. Self-repair without the authorization of our company or losses caused by disassembly by those who are not responsible for the repair of the three guarantees;
5. After the validity period of the three warranties expires, it can still be used after repair;
6. Damage caused by force majeure;
7. Damage caused by disassembly by non-Haier service providers.
Detailed information:
1. Judgment based on purchase date of invoice. No other warranty certificate is required during the warranty period. The energySolar purchased in September 2010 requires purchase invoice, warranty card and product manual to receive extended warranty service for designated major components.
After September 30, 2010, you can enjoy the extended warranty service for main parts with the purchase invoice and product manual. Determine the required certificate based on the purchase time on the invoice and the description of the warranty period on the manual.
2. If there is no invoice, search for the product number and the product production date will be extended by three months from the date of purchase;
3. If two elements are missing, the user will not benefit from the product. Free warranty service, subject to billing guide price;

Of course, it is at the inside the water tank, open and under pressure. All can be usedespecially those with stainless steel coatings. Chloride ions in water will corrode stainless steel welds after high temperature, resulting in water leakage. The anode magnesium rod is used to let the chloride ions corrode the magnesium rod first. victim. The magnesium rod lasts 3 years. It must be replaced.
Jiangsu Guangguang Group enamel coating is also equipped with magnesium anode rods. The enamel itself has no welds. After installation, it can be said that it is double assurance, and the water quality is clean and non-corrosive.
