As people's quality of life improves, bathing has become more and more convenient. Electric water heaters have become one of the essential appliances in the home. However, in recent years, electric water heaters have frequently encountered electric shock accidents, and bathing has become " Deadly Bathing "! Should you cut off the power while taking a shower? How to use a water heater safely? Come on, follow the passers-by and listen to the passers-by.

electric water heater

my country first used water heater in the 1970s. The water heater that was just beginning was a gas-type water heater, which was mainly heated by gas combustion. Electric water heaters entered our country in the 1990s. Due to their convenience of use and small size, they quickly became popular among people. With the development of society, there are more and more types of water heaters.

gas-type water heater

Currently there are three types of electric water heaters on the market, one is water storage . This kind of water heater is usually common. It contains heating rod . It can be heated directly by plugging it in, and the inner liner can store hot water. The advantage is that the water outlet is stable and can be used without power. It has high safety performance, but the heating time is relatively long. If there are too many people at home, the waiting time will be longer.

The second and three types are instant-heat and speed hot . The common characteristics of these two are that heat is fast, fast as few seconds, and slow as many as you want, hot water will be available in a few minutes. If you open it, use it without needing to use it, it will be more cost-effective. However, this kind of power is relatively large. The water storage type is usually between 1.5-2KW, while the instant-heat type is around 5-8KW, which requires a high power supply.

Why does taking a bath become a "deadly bath"?

In recent years, there have been many casualties caused by water heaters, and most of the reasons are caused by electricity leakage. According to the "China Household Electricity Environment Survey Report" released by the Chinese Consumer Association , about thousands of people suffer casualties due to leakage of water heaters during bathing every year. On average, three people in have dangerous when taking a bath every day.

"Fatal Bath" incident in my country in recent years :

In February 2016, a water heater in a rental house in Baiyun District, Guangzhou leaked, and two women were electrocuted and died. It is understood that one of the tenants leaked while taking a bath at the time of the incident, and the other woman was also electrocuted and killed by electric shock during the rescue.

In June 2017, a woman in Shenzhen was electrocuted while taking a shower and died after failed rescue on the scene.

In December 2020, a man in Zhengzhou was unfortunately electrocuted while taking a bath in a rental house.

In September 2021, a 12-year-old boy in Puyang, Henan Province was unfortunately electrocuted while taking a shower.

Why does the water heater leak? There are usually three reasons why water heaters leak electricity. is the quality problem. There are many types of water heaters on the market and the quality is uneven. For example, some miscellaneous water heaters are unqualified in order to reduce costs, or fail to pass the national standard "three-no products", which can easily lead to leakage during use.

The second is wiring problem . Some qualified water heaters will also have leakage if they are not wired correctly, such as ground wire failure, use of inferior sockets, wrong wire connections, etc. Previously, consumer associations in various parts of my country and quality supervision departments conducted a sampling survey on residents' electricity wiring in more than 20 cities across the country. The results showed that among the 2,386 households, only 576 households fully met the standards, with an unqualified rate of up to 75.9%. The main problems include the ground wire location not meeting the standards, the unreasonable layout of the lines and sockets, etc.

. The use time is , and electrical appliances have a certain lifespan. The safe service life of the water heater is 8 years . After the use time is too long, internal parts or lines will have aging problems, and safety hazards are easily present during use. In addition, the water heater must be regularly maintained and repaired during the circuit to effectively avoid safety hazards.

Should the water heater be powered off when used?

Many people believe that unplugging the power supply when using a water heater is definitely the safest. This is true, but it is limited to water-storage water heaters. After unplugging the power supply, there is still hot water. If you use an instant hot type at home, you cannot unplug the power supply. So for safety reasons, should you turn off the power when using the water heater?

Although "deadly bathing" incidents occur from time to time, the water heater is not as unsafe as everyone thinks. As for the power outage during use, it can be determined by the following points: First, choose a water heater of a big brand , and the quality is guaranteed; Second, install , check the relevant certificates of the master during installation and confirm that it is a professional. In order to save costs, some merchants will cooperate with some electricians who are randomly looking for. is to wire , and you must connect to the ground wire, so that even if the leakage is leaked, it can be controlled within the safe range to avoid casualties. If there is no problem with

or above, it is okay to turn off the power when using the water heater. It can be determined based on the frequency of use. If it is used every day, it can be powered on continuously. If it is not used for more than 3 days, it can be powered off and plugged in again when using it.

What should I do if I encounter someone’s electric shock?

Note, don’t pull it directly with your hands! Because it is very likely that both of them will be electrocuted. In August 2019, a pregnant woman in Shenzhen accidentally got electrocuted while taking a shower. Her husband was also electrocuted when she was rescued. In the end, both of them were electrocuted and died. If someone accidentally gets electric, the power is cut off first, such as pulling the switch. If it cannot be found, you can use an insulator to remove the electric shock from the electric shock position before rescue.

Who should I ask for compensation for an electric shock accident? In July 2016, a woman in Daxing, Beijing was electrocuted due to electric leakage in a water heater while taking a bath in a rental house. It is understood that the water heater used in the house has been used for 9 years, exceeding the safety period, so the landlord should bear the main responsibility, and the landlord was finally ruled to compensate 739,000 yuan.

Also, in April 2019, a girl in Changde, Hunan was electrocuted while taking a shower. After investigation, it was found that it was a leakage caused by installation problems. The merchant was finally determined to compensate 850,000 yuan.

Nothing is a trivial matter! During the use of electric water heaters, you must pay attention to their service life, and also need to be inspected and maintained regularly. If you don’t understand, you can find a professional to check it out.
