Regarding the problem of electric water heaters, the use of electric water heaters is misunderstood

I have a Haier electric water heater at home, and the quality is very good for many years. Two people can buy about 50 liters, and the safest way to use an electric water heater is to unplug it when taking a shower.

You can consider solar water heaters, which have the advantages of saving electricity, and the temperature of the water is uniform, making it very comfortable to take a bath.

If you are far away from the top floor (you live on a lower floor), you can connect the water pipe to the inside of the wall through the ventilation hole in the bathroom.

Two old people can use 30 or 40 liters. The volume is large, the space occupied is also large, and it also costs electricity.

Solar water heaters are recommended (at the same time, with electric heating function; can be turned on or off as needed).

Its safety and temperature are superior to electric water heaters and gas water heaters. Wash vegetables and bathe throughout the winter, and there is hot water throughout the day.

I am in Wuhan, and the atmospheric temperature is 30 degrees Celsius according to the weather forecast, and the temperature of the solar water heater is 99 degrees Celsius every day (which is the highest display temperature). In winter, the temperature is generally in the 60s (electric heating is rarely required).

The newly produced water heater is not very safe due to design defects in both electricity and gas, but now the hidden dangers in safety have been solved. You can buy with confidence. It's really convenient to have such a thing in the home machine.

The filial piety to the old man is very admirable.

Although electric water heaters are commonly used appliances in the home, they should not be used indiscriminately, as the wrong way to use them may cause malfunctions. Let's take a look at the misunderstandings of electric water heaters!

Myth 1: Using a qualified electric water heater is foolproof

Many people think that buying a qualified electric water heater is once and for all, and they don't need to pay too much attention. In fact, this is not the case, even a qualified electric water heater may be buried with the risk of leakage. This is because the cause of leakage may be the aging of internal parts, damage to the insulator of the power line, etc.

So, don't take it lightly and get regular check-ups.

Myth 2: The use of leakage protector is to completely ensure the safety of bathing

When the electric water heater heats cold water, if there is leakage, the leakage protector will cut off the power supply within seconds to ensure the personal safety of people. However, one of the power cords of the electric water heater is not grounded, mainly used to ensure the safety of electricity, if this power cord is damaged, the current will not pass through the leakage protector and directly enter the inside of the water heater, so it is difficult to avoid not hurting people with electricity. Therefore, the use of leakage protector cannot completely eliminate the occurrence of electric shock accidents.

Myth 3: Unplugging the power means that the bath is safe

If you buy a storage type electric water heater, you should heat the water before bathing and store it in the water tank. Some people will unplug the power plug before taking a bath, because the water in the water heater tank can already meet the shower's needs. But this does not mean that electric shock accidents will not occur, because the water heater is connected to the water pipe in addition to the electrical circuit.

If a household's water heater leaks, then the water pipes of the entire building will also become electrified. Therefore, when taking a bath, it is best not to touch the water pipe, so as not to be electrocuted by the current introduced by the water pipe.

1. When the water heater is heated, should the hot water valve be closed or opened?

The hot water valve can be opened and closed when heating, and it must be fully open when in use.

2. The pointer of the thermometer rotates slowly, rotates the temperature adjustment button to about 60 degrees, and after heating for an hour, the pointer reaches the middle position of L and H, is this normal?

It takes hours for the water heater to heat 50 liters of 1500 watts to a maximum of 75 degrees, which of course seems slow. The mechanical temperature control display is approximate and inaccurate, so you feel like it's 60 degrees, maybe it's 70 degrees. So heating for 1 hour is normal for the hands to the middle position.

Maybe it's the middle of the heat.

3. Does heating for one hour use 1 and a half kilowatt-hours of electricity?

Constant heating is the loss of electricity per hour.

4. After the power is unplugged, will the temperature of the hot water become cold by itself?

Because of the temperature difference, the temperature in the water heater will gradually cool down, but it is very slow, generally a good brand water heater can reach 72 hours of hot water, that is, after heating to 75 degrees, it will not heat or use water for 3 days, and it can still release water higher than body temperature.

Unplugging or turning off the power just makes the water heater stop heating automatically.

1. Is the hot water valve you mentioned a drain valve, if so, of course it should be closed.

2. It depends on whether it is winter or summer, heating is faster in summer, and whether water is used during heating, if it is water, it should be normal.

3. Depending on the temperature you set, the low and high temperature settings are not the same, if you continue to heat for an hour, it is 1 and a half degrees.

4. After the power is unplugged, the temperature of the hot water will become cold if it is not heated for a long time, and it should be able to be maintained for about two days.
