The water heater should be washed once a year.

The range hood should be cleaned after a certain period of time. This common sense is known to many people. Do you know that the water heater liner also needs to be "bathed" regularly? Recently, Ms. Wang of Dalian City, Liaoning Province reported to the newspaper that she used 3 Because the electric water heater of the year is not as efficient as before, please come to the after-sales service personnel to clean it, and even discharge 2 large basins of sewage, which is shocking.

Ms. Wang told reporters that her home's water heater has a capacity of 45 liters and has been used for 3 years and has not been cleaned. Recently, she felt that the water heater was not as good as it used to be. I asked the master who installed the repair service center to clean it. I didn't expect to wash out 2 large basins of sewage.

Usually the water in the bath is quite clean, how can there be so much dirt? Originally, inside the water heater, the hot water nozzle is at a high place, about 2 cm from the top, and the cold water pipe is at a low point. The bottom of the gallbladder is about 3 cm. When the water heater is used normally, the cold water pipe is always in the water. The hot water is squeezed to the top by the cold water, and the water is discharged along the hot water pipe. The scale is deposited on the bottom of the inner tank and will not be discharged through the hot water pipe. If it is not cleaned for a long time, scale will adhere to the heating rod, resulting in slow heating.

Master Liu, who is engaged in the maintenance of water heaters, told reporters that the water stored in the electric water heater does not flow for a long time and is easy to precipitate in the inner bladder, which will not only cause the water quality to drop, but also prolong the heating time and consume electricity. He also told reporters that the electric water heater is equipped with a sewage outlet, which can be discharged according to the instructions. If there is no sewage outlet, ask a professional to clean it. “The electric water heater can be cleaned once a year. The scale of the inner tank provides a breeding ground for the bacteria, which may cause skin redness, allergies and other symptoms, which not only consumes electricity but also harms health.”
