Usually, it is burned from the electric energy-saving water heater in the boiling water room. These waters, known as "thousand boiling water" due to repeated boiling, can produce carcinogenic substances such as nitrite. The so-called "thousand boiling water" is actually a type of "aging water". In addition to containing harmful substances, drinking it can also affect normal metabolism in the human body. Experts suggest that it is better to drink purified water. Of course, it is also important to drink fresh purified water from the water dispenser, as it should not be consumed if left for too long.

Traditional electric water heaters do have "thousand boiling water" due to structural issues, which is the water repeatedly boiled in the electric water heater. Due to prolonged boiling, the content of non-volatile substances such as heavy metals such as calcium and magnesium, as well as nitrite, is very high in "thousand boiling water". Drinking this type of water for a long time can interfere with a person's gastrointestinal function, leading to temporary diarrhea and bloating. Or it can cause hypoxia in the body, resulting in symptoms such as dizziness, breast tightness, and nausea. If it is the elderly, children, pregnant women, weak and sickly individuals, long-term consumption of this water may cause greater harm.

In addition to boiling water, ordinary floating ball electric energy-saving water heaters also have "yin and yang water". The so-called yin-yang water refers to the water that is mixed with boiled water, and the other is the water that is reheated after being mixed, also known as reheated water. When the water in the energy-saving water heater is insufficient, it will automatically add water. At this point, if the person receiving the boiled water is not paying attention or is in a hurry to drink, the electric water heater will discharge yin and yang water. Yin Yang water may contain various pathogenic microorganisms, so drinking Yin Yang water may lead to various intestinal infectious diseases. However, the content of nitrite in the returned water is relatively high.

The emergence of step by step direct water dispensers not only prevents this kind of "thousand boiling water" and "yin-yang water", but also prevents scaling, ensures fresh water quality, and eliminates secondary pollution.
