1. The working principle of an electric water heater: turn on the heating, do not do insulation, and cannot completely separate raw water from drinking water. There is a float switch on the top right side. Turn on the faucet to drink water, and the float at the top will drop. The switch valve will then open, and the raw water outside will flow directly into the water tank. Fill the water tank to keep the float at the top. Mixing raw water and boiling water can easily form "yin-yang water". People who drink water will permanently drink "semi raw and semi cooked" yin-yang water.

2. The harm of yin and yang water: if people drink "yin and yang water" for a long time, it will harm their health, and the possibility of suffering from bladder cancer cancer and rectal cancer will increase by 21% -38%.

3. The Composition of Thousand Boiling Water: When heating is turned on, insulation is not applied, and the temperature is announced quickly, the water temperature inside the water heater will drop when the water is not used for a long time. When the water temperature drops to a certain temperature, the equipment will continue to heat to form Thousand Boiling Water

4. Drinking "Thousand Boiling Water" for a long time can interfere with the gastrointestinal function of people, causing the nitrite content in the water to exceed the standard, which is harmful to human health and prone to temporary diarrhea. Over time, it can also cause cancer.

5. Unhealthy, electric water heaters do not undergo purification treatment before use. Although boiling water can kill viruses, impurities still enter the body together with water. Turning on the heating can cause secondary pollution of water during equipment operation, making it unhealthy.

6. Inconvenient, high temperature hot water, no water temperature regulation system, unable to handle the problem of students having difficulty drinking water for ten minutes during break time. Unsafe: No self-control system, no leakage protection device, prone to electric shock risk, high temperature boiling water is prone to scalding, and there is an unsafe risk.

7. Not energy-saving; Heating turned on, no energy-saving function, no insulation done, high work cost.
