Can water from a water heater soak noodles

It is generally not recommended to use water from a water heater directly for making noodles, as it may pose a hygiene hazard. Long term storage of water in water heaters may breed bacteria or accumulate scale, and direct consumption may affect health. The water temperature of a home water heater is usually maintained at 40-60 degrees Celsius, which cannot effectively kill bacteria and microorganisms in the water. The inner tank of a storage water heater may accumulate impurities such as scale and rust, and repeated heating can also lead to an increase in nitrite content. When brewing instant noodles with this type of water, high temperature contact with plastic packaging may also release harmful substances. Although some instant gas water heaters can quickly produce high-temperature water, there is still a risk of contamination when the pipelines are not cleaned for a long time. If the central hot water system in commercial premises is not regularly disinfected, it is even more difficult to ensure water quality safety. In special circumstances, when using a water heater to soak the surface, it is recommended to boil the water for 1-2 minutes to sterilize it, and avoid using hot water stored for more than 24 hours.

It is recommended to use fresh boiled drinking water for daily instant noodles, which can ensure food safety and make the noodles easier to steep. If you need hot water to brew food for a long time, you can equip it with a dedicated electric kettle and regularly clean it. Pay attention to the water heater manual, as some products will clearly indicate that they cannot be used as a drinking water source. If discomfort symptoms such as diarrhea occur, seek medical attention promptly.
