Do you need to power off the electric water heater? The electric water heater is powered off.

Some people use electric water heaters at home. After using the electric water heater to turn off the switch, some people will still have doubts about whether or not the power supply is completely cut off. Does the electric water heater run out of power? Some people think it is necessary to use the electric water heater. Power off, so that there is no leakage, what should you pay attention to when the electric water heater is powered off?

First, do you need to power off the electric water heater?

need.

1. Instant electric water heater

Instant electric water heaters usually have a power of 5-8KW, and require at least 4 square meters of power cord, but with automatic frequency conversion thermostat function, bathing does not need to wait for hot water, ready to use, unlimited supply of hot water, anti-scaling, how long How much water and electricity should be used to avoid unnecessary waste of water and electricity; when turned on, turn it off when not in use.

The instant electric water heater uses a honeycomb heating body and a partition wall. By extending the water inlet and outlet, the tap water itself has the physical properties of the resistor to increase the electric resistance and reduce the current to an acceptable safety value. Instant electric water heaters have zero-sequence mutual inductance coil components. When leakage occurs, the currents in and out are not equal, and the leakage protection function will be triggered immediately. The water heater will stop working immediately. The location of the inlet and outlet of the electric water heater is connected to the ground wire. When installing the instant electric water heater, the ground wire of the power line should be connected reliably. If there is leakage, the current will flow through the ground. Earth, to ensure the safety of users.

2, storage type electric water heater

The storage type electric water heaters are conventionally equipped with 40L, 80L, 60L, 100L, 120L, etc., and need to store water for 1-2 hours before bathing. The waiting time is long, it is easy to scale, and the cleaning and maintenance troubles. It can be used by several people for a short time, but it needs to be re-storage water after the hot water is used up.

When taking a bath with a water storage type electric water heater, you can disconnect the power supply and then take a shower. In the winter, if hot water is frequently needed, it needs to be plugged in for a long time, and the water storage type water heater has the function of automatic heating. As long as the temperature inside the water heater is lower than a certain value, it will be automatically energized and heated, so the heating is repeated until The maximum temperature causes a waste of electricity.

Second, what should pay attention to when the electric water heater is powered off

1. The water storage type electric water heater is the safest after powering off the water. The safety of the electric water heater is mainly referred to as the safety of electricity consumption, that is, whether leakage will cause harm to the human body. After that, there will be no leakage problem, it is safe, but after taking a shower and then taking a shower, the water heater manufacturer's added functions like “speed heating capacity” cannot be used.

2, the current water heater with the continuous improvement of the technical level, the use of leakage protection or anti-electric wall design, basically can ensure that the possibility of personal injury caused by leakage can be avoided, it can be used normally.

Do you need to power off the electric water heater? If the electric water heater is used up, it is better to power off, which is also a way to save resources. What should you pay attention to when the electric water heater is powered off? When the power is off, remember to keep your hands dry. Do not touch the power-off protection device when the hand is wet.
