CCTV Finance ("Is it Real") Hot summer is the season when bathing is most frequent. Recently, an article claimed that electric water heaters that have not been cleaned for many years can easily accumulate harmful substances or have the risk of causing various skin diseases. Is there any basis for this statement? With a deeper understanding, the reporter found that many netizens had exposed the scale existing in their water heaters. Is there really so much scale in the electric water heater? In order to verify the truth, reporters from the "Is It Real" column of CCTV Finance and Master Yin, a professional cleaning water heater, worked together to clean the electric water heater that had been used in the user's home for six years and had never been cleaned.
After the power is cut off and the water is released, Master Yin will take out the heating rod of the water heater. How much scale will there be in this electric water heater that has been used for six years and has never been cleaned?
Master Yin: There is so much scale on the heating rod that I can’t even pull it out. I’ve never had to pull the heating rod so hard. What I usually see is that there are layers of crusty scale on it. This one has been smeared. full.
Even Master Yin has rarely encountered heating rods covered with so much scale. Then the reporter used his mobile phone to take pictures of the water pipes inside the water heater's inner tank. There was also a large amount of scale attached to the water pipes, and scale remained at the bottom of the tank. Next, Master Yin poured out the scale at the bottom of the tank. Along with the scale, there was also yellow sewage. In the end, half of the basin of sewage and the scale on the bottom of the basin were cleaned out of this electric water heater that had been used for six years.
Next, Master Yin cleaned an electric water heater that had been used for about two years. Does it mean there is no scale due to its age? Judging from the cleaning results, electric water heaters that have only been used for two years also have scale and sewage. Why does scale or even turbid sewage appear in water heaters?
Master Yin, a senior household appliance cleaning practitioner: We all know that water contains a lot of minerals, and water will produce some precipitation after being heated in a water heater. Over time, the scale we see will form. Some turbid sewage will also be deposited at the bottom of the water heater.

The sewage in the water heater is produced with the increase of scale. But why is the water seen when taking a shower clean?
Master Yin: When taking a shower at the hot water outlet of the water heater, the water flowing out of the shower head is relatively clean water from the top. Only after we clean it can we find the turbid sewage. Therefore, we recommend that you clean your water heater every one to two years.
So if the electric water heater has not been cleaned for a long time and produces a lot of scale, will there be any health risks when taking a shower? The reporter interviewed Cao Mei, deputy chief physician of the Department of Dermatology at Beijing Chaoyang Hospital.
Cao Mei, deputy chief physician of the Department of Dermatology, Beijing Chaoyang Hospital: Storage-type water heaters are what attract the most attention, because part of the water always remains at the bottom and cannot flow, so it is inevitable that some bacteria will breed. One of the most common cases is a woman who has recurring urinary infections. Every time she connected the electric water heater to the bathtub, she had to clean her perineum. This was because the water was chronically irritated by the bacteria, which caused her to have repeated urinary infections. So from this point of view, the use of our electric water heater still requires our attention.
