In recent years, electric water heaters have been favored by consumers because of their convenience and safety. Many users do not know that electric water heaters also need regular maintenance, otherwise there will be big problems.
Recently, the electric water heater of Mr. Wang's home in Ruyi Community was not well discharged. After looking for the repair of the appliance repair personnel, a lot of scale was removed from the water heater. It was the scale that blocked the water outlet of the water heater, which caused the water to be poor. How can there be so much scale in the water heater? According to the maintenance personnel, the water heater will add a magnesium rod to the inner tank in order to prevent scale. The magnesium rod can play a role in slowing the corrosion of the water tank liner by the water alkali and scale in the water storage type electric water heater. However, once the magnesium rod is consumed, if it is not replaced in time, it will easily cause scale, and it may cause corrosion of the liner or corrosion of the heating tube, which may cause electric leakage and cause personal injury. Our city is located in the northern part of China. The tap water we usually use contains a certain amount of calcium bicarbonate. When it is heated, it will decompose into calcium carbonate and precipitate on the bottom of the water heater. Anyone who has used an electric kettle in general knows that the electric kettle has been used for a long time, and a thick layer of scale is formed on the wall. In fact, the principle of the water heater is the same. Mr. Wang’s electric water heater has been used for nearly ten years. It is never known that the maintenance of the magnesium rod is due to the fact that the magnesium rod has been exhausted and the scale is rapidly accumulated, and the water heater is not well discharged.
Remind consumers that the water heater should also contact the relevant after-sales service department to check and repair the magnesium rod after several years of use to ensure the safe use of the electric water heater. If the water flow rate of the water heater is getting smaller and smaller, the consumer should check whether the water tank's inner tank contains scale and whether the magnesium rod is corroded by water.
