What chemicals have been added to the heated water?

Hot water contains potassium ions, chemicals for descaling and deoxidizing, and preservatives (such as caustic soda, tannin extract and sodium phosphate), and cannot be used for washing clothes.

The water in heating boilers and heaters is not ordinary tap water, but chemically treated softened water. Tap water is exchanged with sodium ions to obtain water. With the constant exchange of sodium ions, softened water is produced. When sodium ion fails, it needs to be washed with salt water and then with tap water until it is qualified, so that sodium ion can recover its performance. It is so repeated that softened water is always used in boilers.

Demineralized water is not salt water in the general sense. It is not salty, contains neither iodine nor trace elements such as calcium and magnesium needed by human body, and can never be drunk.

Moreover, the heating water also contains preservatives, such as caustic soda, tannin extract and sodium phosphate. These are harmful to the human body. Washing vegetables and clothes with such water is very harmful to people's skin and health.

Hazards of using hot water:

1, the water in the radiator contains chemicals that are easy to harm the skin. The water of radiator belongs to industrial water, which is softened water specially treated by the heating company and added with many chemicals. Washing feet with radiator water is easy to damage the skin, and if there is trauma, it is easy to cause wound infection.

2. The water in the radiator is closed and circulates for a long time. Water contains a lot of germs and chemicals, so it must not be used for washing vegetables, let alone drinking.

3, private water, easy to lead to water pressure drop, affect the radiator heat dissipation. The heating company sets the heating water pressure according to the building height and other factors. Under normal circumstances, the heating water pressure will not be adjusted. If the water in the radiator is released privately for a long time, it will not only affect the heating of high-rise residents, but even affect the heating of their own homes.
