When using a water-storage electric water heater, first fill the water heater with water, then turn on the power supply, and use it after preheating. If the pressure of the water source drops or the water is cut off, it is best to turn off the power. When the water heater is on the water, the water outlet should be opened at the same time, and the air in the water heater inner tank should be cleared before checking whether the water is full. On the temperature regulator of the electric water heater, there are generally signs and scales for the water temperature, which are used to indicate the low, medium and high adjustment positions of the water temperature. As long as the knob of the temperature adjustment is pointed to a certain scale, the water temperature of the water heater will remain in the current temperature range for a long time when it is working. Of course, it is best to test the water temperature before using it.
