As the weather gets hotter, the use of water heaters has also entered a peak period. As a scientific and technological product promoted by the state in recent years, the water storage test water heater has quickly occupied the market and entered thousands of households with its advantages. However, the reporter found in the interview that in the current water heater market, the problem of bacterial growth in the water storage tank is a chronic disease that is difficult to overcome by traditional storage water heaters.
[Shocking] The water tank becomes a breeding ground for bacteria According to the survey by authoritative organizations, 20% to 30% of the water in the storage water heater is dead, and there is a phenomenon of repeated heating hundreds of times a day. The continuous heating of hot water for a long time not only wastes energy, but also provides favorable conditions for the growth of microorganisms and bacteria in the water storage tank and pipeline, producing a large number of bacteria such as Escherichia coli, Salmonella and nitrite, which make the water in the water heater. severely polluted. Li Guoxing from the Marketing Department of Zhejiang Zhengli Biotechnology said that since the water return in the storage water heater is not very good, and it is impossible for residents to use up all the water at one time, this means that there must be leftover water in the water heater. Since the inner tank of the storage water heater is kept at 40℃~60℃ for a long time, this temperature value is suitable for the mass reproduction of bacteria. A breeding ground for bacteria. There are various pathogenic bacteria in water, including anaerobic bacteria and aerobic bacteria, such as Escherichia coli, Streptococcus, Bacillus, Salmonella, flagellates, typhi, etc.
"It's not just water storage water heaters, air energy and solar water heaters are actually facing bacterial problems." Li Guoxing said that the current leading products in the water heater industry are water storage products, and water storage electric water heaters generally have the problem of "stagnant water". Dead water refers to the water stored in the electric water heater, the use interval is slightly longer, and the water quality has secondary pollution. Because the water that does not flow for a long time is easy to hide dirt and bacteria in the dead corners of the inner gallbladder. In this case, can the water boiled by the water heater still be used? Does it mean that the quality of the bath water we use is unqualified?
Li Guoxing said that there is no specific standard and quantitative index for bathing water in China, and there is no way to judge, "There is no problem with bathing, but it is best not to use the water in the water heater for cooking, washing dishes, washing fruits, or even cooking. "
[Consumer Reminder] It is best to take a shower every two months. In order to solve the problem of "bacteria", many electric water heater manufacturers have successively launched storage-type electric water heaters with sterilization function, such as using silver ion antibacterial technology to inhibit water Escherichia coli, Salmonella and other bacteria and viruses that endanger health. "These water heaters with sterilization function can alleviate the bacterial problem to a certain extent, but they cannot be cured." Li Guoxing pointed out, "When bathing with hot water, the pores on the body are open, if the water contains rust, impurities and heavy metal ions, etc., Long-term use can cause damage to the skin, resulting in dandruff, acne, eczema and other skin diseases.”
According to home appliance expert Luo Qingqi, now, the emergence of the instantaneous electric water heater is expected to solve this problem. The water heater has no inner tank, the water flows directly, does not store water, does not repeat heating, and does not produce scale, which completely solves the problem of water pollution. To achieve zero pollution of healthy hot water. Moreover, the rapid magnetic heat conduction technology is used to convert water into magnetically active small-molecule water, which makes it easier for the human body to absorb various mineral nutrients. Long-term use can enhance human immunity and meet consumers' requirements for healthy hot water. The service life of the water heater is about 10 years, and it should be overhauled when the service is overdue. At the same time, it is best for the public to clean the water heater once every 2 months. Experts from Henan Provincial People's Hospital pointed out, "The cleaning method is very simple. First cut off the power supply and close the water inlet valve, then unscrew the water outlet valve to drain the water and sediment in the water heater. Finally, rinse the water heater with tap water. After completion, restore the drain switch to its original position, and pay attention to power on after it is full of water.”
