What is the highest temperature of electric water heater stipulated by the state?

At present, there is no national regulation, only industry (enterprise) standards. The industry standard is: electric water heater does not exceed 75 degrees, and gas water heater is 65 degrees.

The instant electric water heater is "running water" because cold water directly passes through the heating element and then is heated, so the scale is not easy to stay, and the temperature of hot water is generally not higher than 55℃ when bathing, so the scale is not easy to form in the internal pipeline of the water heater. Moreover, during the heating process of the hot electric water heater, the temperature rise of the machine heating is not very high.
