In the hot summer, many people like to take a shower and feel clean and refreshed. But are you really cleaned every day? The citizen Wang heard that “the water heater does not clean for three years, it is equivalent to taking a bath with sewage†because the tank is not cleaned for a long time. There will be serious scale and rust, is this true? The reporter conducted a survey.
Water heater does not wash out half a basin of scale for 3 years
"The water heater is used every day. There should not be so much dirt left. My water heater has been used for almost five years, but it has been repaired and there is no internal cleaning." Ms. Feng said. The reporter learned through random interviews that many people do not understand whether the water heater needs cleaning.
Master Zhao, who has been engaged in electrical maintenance for many years, believes that the water heater does need cleaning. He introduced that he had cleaned the water heater for three years, cut off the power supply, and removed the heating rod to find the scale on it. Next, close the triangular valve, unscrew the nut of the cold water port and the hot water port, and connect a hose to the cold water port of the water heater. The water in the water heater slowly flows out through the pipe. “The water from the water heater will slowly turn grayish black, accompanied by yellow dirt deposits, which can have more than half a basin. This is just the sewage at the bottom of the water heater tank.â€
After the water in the liner is cleaned, it is necessary to start cleaning the liner, and it will become clear after washing at least five times. The water heater used for three years is already dirty enough. Master Zhao said that this is actually nothing. It also cleaned up the half basin of scale. He once washed a water heater that had not been cleaned for five years, and only the scale was full. Full of pots. “There are very few customers requesting to clean the water heater. Generally, when the water heater is broken, it will be cleaned after a large amount of scale is found during maintenance.â€
Scale damage can not accumulate a lot of hidden dangers
Why is it that the scale is equal to the sewage bath? Originally, the water tank hot water outlet of the pressure-type electric water heater is at the top of the liner, and the inlet of the cold water is at the bottom of the liner. Therefore, the water used in the bath is the relatively clean water at the top, and the scale will precipitate near the bottom. However, if there is too much accumulation, it will bring out some dirty things every time you take a shower. The shower shower takes a long time and gradually gets out of water. It is because the scale is blocked by the scale. If you look carefully, you can see it. Scale on the shower.
"The first problem is impurities, which can easily lead to skin allergies." Xu Xuelu, secretary general of the Jiangsu Household Appliances Maintenance Association, said that long-term precipitation and accumulation have caused the harmful substances in the water to increase, and the slime, microorganisms and bacteria have been continuously updated and alternated for a long time. A lot of harmful substances have also been generated. In addition, it will increase the energy consumption. If a large amount of scale is attached to the heating rod of the electric water heater, the heating efficiency will be greatly affected. Generally, as long as it burns for 45 minutes, the scale must be burned for 60 minutes, and it is felt that "the hot water is not hot." ".
The most dangerous thing is to affect the safe operation. If the scale is thick, the liner will overheat and deform, bulge and even rupture. If it is very dirty, even the scale inside the water pipe will completely block the pipeline, destroy the water circulation, and cause a pipe burst accident in severe cases.
The water heater can be cleaned once in a year or two.
"Under normal conditions, the water heater should be thoroughly cleaned every three years." Xu Xuelu said that because deep cleaning requires opening the maintenance port, it is best to ask a professional repairman. "If you have tools, you can understand some mechanical and electrical principles, you can also clean them yourself, but you are afraid that some consumers will not be able to remove them, especially if the seal is not easy to leak." Everyone can usually go every one or two months. Perform water discharge maintenance to reduce the accumulation of scale. If there is a pipe attached to the water heater, it can be connected to prevent dirty water from splashing everywhere. The public can call the manufacturer hotline to request home cleaning, or through the association WeChat "home appliances 315" to query the regular manufacturer phone. At present, the water heater is cleaned once, and the price ranges from 80 yuan to 120 yuan depending on the brand.
In fact, in addition to the water heater, the washing machine will also taint dirt, and need to "bath" regularly. “The interlayers in some washing machines are easy to absorb dirt. These dirt mainly come from scale in tap water, free detergents, cellulose in clothes, organic matter in the human body and dust and bacteria brought in by clothes.†Xu Xuelu suggested that the public should be inside the washing machine. It is best to clean the tube once every six months or so, and use a professional washing machine inner tube cleaner, which is relatively simple.
