It is best not to use it for cooking. In theory, solar water tanks are made from food-grade stainless steel and can be used as long as the water supply source is clean. However, if solar energy is used for a long time. time, there will be a lot of sediment inside, i.e. scale. I have seen some very dirty ones. Another point is that the water inside is retained for a long time and cannot be completely discharged. exported. The water can It is completely empty, and we cannot see the steel actually used. Even if we see it, we don't know if it is harmless to the body! ! !
Can the water from solar water heater be used for boiling water and cooking?
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 the most common coliforms and heat. resistant coliforms in the body of water will also multiply over time. At present, drinking solar water with excessive microbial content will affect health humaine.
It is generally not recommended to use it for boiling water or cooking, but it is still possible to use the water inside for bathing.
It is best not to use the water from solar energy as drinking water, but only for bathing and washing, because although most of today's water tank barrels are made of of imported food grade stainless steel plates, there is no guarantee that the connected water pipes can achieve food grade performance.
Especially when the connected water pipe encounter hot water at a higher temperature, the harmful substances in the water pipe wall will be dissolved in the water, so it is recommended not to use solar energy water to cook or drink. What's more, when you use it, you don't refill it every day after using it,but you refill it immediately after using it each day. This way there is always water left for a long time. in solar energy. This type of water is repeatedly exposed to the sun, which is very harmful to the body.
