No, the water tank of the solar water heater is equivalent to a small water storage facility, and the water stored in the solar water heater is secondary water storage. However, the safety of solar hot water transmission and distribution equipment, protective materials and water treatment materials has not been tested in accordance with the “Water Monitoring and Administration Measures drinking water” and “Health standards for living drinking water”. the water tank has poor health protection and cannot be cleaned and cleaned regularly. Disinfection does not meet the conditions of secondary water supply. At the same time, when the water in the solar bucket is between 40 and 60 degrees Celsius, since the bucket is not a pure vacuum environment, it will provide a breeding ground for microorganisms in the water , as well as for coliforms and the shortest heatants. resistant coliforms in the body of water will also multiply over time. At present, drinking solar water with excessive microbial content will affect human health.
Can the water from the water heater be used for cooking?
It cannot be used for cooking.
Whether it's a solar water heater, gas water heater or electric water heater, most manufacturers will indicate "not intended for consumption". in their product manuals. Although the water entering the water heater is clean tap water, the materials of the water heater's supporting components (such as metal pipes, etc.) can often contain harmful poisons such as lead , cadmium, manganese and arsenic.
In addition, the temperature of the heated water is generally between 40°C and 70°C, which is conducive to the reproduction of bacteria and viruses. Additionally, water heaters with storage functionswater ge have a water storage tank. Over time, bacteria will breed and previously heated water will become contaminated. The water from the water heater is therefore not drinkable!
1. When using a gas water heater in winter, the water temperature may be low. At this time, the water volume should be reduced. After using the water heater, the gas source should be turned off to avoid accidents caused by gas leakage. Check from time to time whether the gas pipeline joints are leaking, whether the rubber hose is intact and whether there are cracks due to aging. Once detected, they should be treated and replaced in time. Replace the battery regularly, usually once every 4 months. However, it depends on the durability of the battery and try to choose a large capacity battery.
2. Before use, the position of each function button should be determined in accordance with the operating instructions.ization. After opening the water tap, the water heater will automatically turn on and discharge hot water. If the water heater cannot turn on automatically after opening the water tap, we should immediately close the water tap and check whether the air source is open, water pressure. , if the pulse igniter works and the battery is discharged, this will also affect the ignition of gas water heaters.
3. Avoid improper operation that causes the water heater to produce only cold water, especially water heaters with hot and cold water conversion features. Once the water heater is paused during use and then turned back on within approximately 10 minutes, the hot water flowing out may be scalding. At this point, you should first drain the hot water accumulated in the water heater for a few seconds before bathing. otherwise, it is easy to burn the skin.
WaterIs hot water from solar water heater harmful to human body when used for cooking?
Cannot be used for cooking.
Whether it's a solar water heater, gas water heater, or electric water heater, most manufacturers will list this in their product manuals .Warning “Not intended for consumption”. Although the water entering the water heater is clean tap water, the materials of the water heater's supporting components (such as metal pipes, etc.) can often contain harmful poisons such as lead , cadmium, manganese and arsenic.
In addition, the temperature of the heated water is generally between 40°C and 70°C, which is conducive to the reproduction of bacteria and viruses. Additionally, water heaters with water storage features have a water storage tank. Over time, bacteria will reproduce and previously heated water willra contaminated. The water from the water heater is therefore not drinkable!
The water in the water heater is constantly flowing in and out, and in order to prevent the water heater from burning dry, the water inside cannot be discharged at the same time. We all know that there is water there. that has been boiled repeatedly cannot be drunk because water that has been boiled repeatedly will produce nitrite and is not good for cooking.
Detailed information
Usually, after each use of the electric water heater, a certain amount of water will remain at the bottom of the tank, which can be reused . Due to water quality problems, the heated water scales on the inner wall of the electric water heater and around the electric heating rod, resulting in microorganisms and impurities in the water a place to breed and again pollutes the water quality in the machine.
There is in factand health risks when people use such water for bathing, especially children, the elderly or people with relatively weak resistance, or people with skin diseases themselves, who will experience itching obvious skin spots and red spots. and other phenomena. Some people also have the habit of using water from water heaters to brush their teeth and rinse their mouths, which is even more harmful.
In addition, when the electric water heater generates scale, it will affect the use effect, slow heating, high power consumption and shorten the service life.
Since the electric water heater is so dirty, why is the water still leaking? Lu Jianguo said that the mouth of the hot water pipe is at the top of the machine and the mouth of the cold water pipe is at the bottom. When used, the cold water hose continues to flow and the waterhot is pressed upwards. cold water. Water flows along the hot water pipe and scale is precipitated on the bottom of the coating.
It is best to clean the electric water heater every 3 to 6 months. It is best to ask a professional to come and thoroughly clean the scale inside the water tank every 1 to 2 years.

I personally object to the poster who drinks the water from the 'solar energy. There are three main reasons:
< p>1. The water storage tank is not up to standard. Heavy metals in stainless steel will leach into water, causing heavy metal safety concerns.2 Since the material eThe foam used around the water tank contains dangerous ingredients, if the seal does not meet the requirements it may enter the water.
3 Microorganisms, bacteria and viruses in water reproduce more quickly at a certain temperature, assuming it is between 50 and 70 degrees, and water in the solar water heater is in this temperature range for a long time. waterEven after boiling, isn't it good for the human body?
