Principle of Haier electric wall-hung boiler

Haier electric wall-hung boiler principle: permanent resistance is formed inside the electric water heater, thus reducing the current value passing through the human body under abnormal conditions. The common standard voltage in China is 220V, and the maximum voltage borne by human body after electric wall treatment is equivalent to 12V, which is lower than safe voltage's 36V, ensuring human safety. Because of the long pipeline, the resistance of the electric wall-hung boiler is relatively large, and the partial pressure above it is quite high, and the partial pressure after reaching the human body is relatively low, which is equal to 12V after calculation, thus ensuring human safety. The answer is applicable to Haier EC600 1-GC and Haier ES60H-HC3(E) brand water heater models.
