electric water heaters has changed people's bathing habits. The price of these products is not high, and you can buy cost-effective products for about 1,000 yuan. However, if the product price is far below 1,000 yuan and there is no 3C certification, then consumers will have to think more about it when buying.
Recently, there are media reports that the relevant domestic appliance association commissioned a third-party testing agency to conduct a sample survey of ultra-low-priced electric water heater products within the unreasonable price range of the e-commerce platform. The results are not optimistic. Among the 27 brands surveyed, there are 28 sets of prototypes of different models, 21 production units, the lowest unit price is 148 yuan, the highest is 368 yuan, and the average price is 253 yuan. After the third-party inspection, the pass rate is only 7.1%.

reported that there are a lot of problems with the 3C certification of the 28 sampled products. Among them, 6 products had problems with the appearance of 3C certification certificates, 4 products had 3C certification certificates revoked or suspended, one had no 3C information at all, and the other had no record information. It seems that buying home appliances in e-commerce companies really can't just be cheap. As ordinary consumers, what issues should we pay attention to when purchasing electric water heaters, and what advantages do reliable electric water heaters need to have? Next, the author will explain for you one by one.
What are the characteristics of a reliable electric water heater?
Before talking about the features of reliable electric water heaters, let's first understand the little common sense related to electric water heaters. At present, the mainstream electric water heaters on the market are divided into two categories : instant electric water heaters and storage electric water heaters . instant electric water heater has faster heating speed, but there are problems such as high price, unstable temperature, and wiring installation requirements. At present, when many household users buy electric water heaters, most of them choose storage electric water heaters.
storage-type electric water heater is mainly composed of inner tank and heating tube . Compared with instant electric water heaters, storage electric water heaters have the advantages of simple installation, large output of hot water, stable temperature, and low price. The disadvantage is that the heating speed is relatively slow and the waiting time after the hot water is used up is longer. long.
So, what kind of electric water heater is more reliable? The author has consulted industry insiders and learned that reliable or easy-to-use electric water heater has three characteristics. First, it has technical advantages and excellent product quality. electric water heater looks simple, but it involves a certain technical threshold for hydropower. For example, in order to enhance the safety of water and electricity, some home appliance companies have used anti-electric wall technology on electric water heaters to make the user's bathing water safer.

span technology is equivalent to adding a 1span 2 span between the hot water heater and the human body resistance wall
The voltage that the human body can withstand is lower than 12V, which becomes a safe voltage and protects personal safety, which solves the problem of electric water heaters themselves.second,The inner material of a good electric water heater is better. At present, most electric water heaters are enamel inner tanks, which are divided into three parts: steel plate layer, sealing layer and enamel layer. For an easy-to-use electric water heater, the steel plate will basically be made of titanium steel , which is not easy to leak water and has excellent pressure resistance.
Among them, the quality of the coating also determines the durability of the enamel liner (anti-corrosion and anti-rust). This is one of the reasons why they sell well but sell well.

Compared with the storage electric water heater, the instant electric water heater has a shorter heating time, and the flow rate can be adjusted to save electric energy. Public data shows that instant electric water heaters save more than 30% of electricity than storage electric water heaters. In comparison, instant water heater saves water and electricity.
On the whole, an easy-to-use and reliable electric water heater must not only be equipped with advanced technology,The body is made of environmentally friendly materials and has to be energy-saving and power-saving.
In addition to the price, what should you pay attention to when buying an electric water heater
Electric water heaters are easy to use, but many friends do not know how to choose. In order to save money and effort when purchasing electric water heaters, most people choose "high cost-effective" products. However, the author thinks that electric water heaters are related to the safety of water and electricity. When purchasing electric water heaters, you should not just look at the price, but also pay attention to the following points: Products with safety technology are preferred, such as electric leakage protection, temperature control insurance and other technical functions. This is also why many netizens worry about leakage when purchasing electric water heaters.

2. Brand issues
A good brand is more secure in terms of product strength, technology and after-sales. At present, the hot-selling electric water heater brands of e-commerce are Midea, Haier, Wanhe, Casa Di, Four Seasons Muge, Sakura, Bosch, Manga AO Smith and Ariston etc.,Products from RMB 1299 to RMB 1999 are the best-selling products with high cost performance, and the performance of products under big brands is more stable.
3. Capacity
The capacity is determined according to the number of family members and the frequency of hot water usage. For example, for a family of 3, about 40L-60L is enough; for a family of 3-4, about 60L-80L is enough; for a family of 6, using 80L-100L to meet the bathing needs .
4. Heating efficiency
Electric water heaters consume a lot of power. From the perspective of power saving and energy saving, many people will regard heating efficiency as the point of purchase of electric water heaters. However, different brands of water heaters are subject to the level of technology, which determines the heating efficiency. From the point of view of heating speed and energy saving, it is more appropriate to start with an instant electric water heater, and it is more suitable to turn off the power after bathing, so as to save the power loss of continuous heat preservation.
5. Humanized functions
In order to bring a better bathing experience, many manufacturers have also developed functions such as healthy sterilization, intelligent control, no-cleaning of the inner tank, and water purification technology. Application, of course, the more features, the higher the price of products, we can choose products according to our own needs. For example, water purification technology. Electric water heaters equipped with this function can not only effectively remove iron filings, residual chlorine and other impurities in the water, reduce water hardness, but also inhibit the formation of scale, thereby reducing skin irritation and damage, and ensuring the cleanliness of bathing water , Allowing users to take a healthy bath. Consumers can choose the functional products they need according to their needs.
