At present, the payment of electricity bills in mainland China is still a "tiered" charge.
The more electricity you use, the higher the unit price of electricity.
As long as the electricity consumption is reasonably controlled, it can completely save a lot of electricity bills.
But many people only know that "use less electrical appliances", but they don't know that "unplugging" is also one of the key parts of power saving.
The meter checker reminded me:
These 5 kinds of household appliances at home must be unplugged when they are used up.
If you don't pull the plug, the electricity bill will "double"!
1. Air conditioning
The meter checker told me,
If you don't use the "energy-saving and power-saving" air conditioner at home, if you don't pull out the power plug, it will consume one kilowatt-hour of electricity for almost 8 days after standby, and if it is 0.5 yuan per kilowatt-hour, it will cost you 2 yuan more a month.
And it not only consumes electricity, but also shortens the life of the air conditioner.
For example, in the old community, if the voltage is unstable, it will be easy to burn the air conditioner, resulting in problems with the transformer or controller.
Therefore, if the air conditioner is not used at home for a long time, we must unplug it as soon as possible and turn off the power to prevent "ineffective consumption" for a long time.
Moreover, in the process of using air conditioners, it is also necessary to develop a good habit of "regular cleaning" to reduce air conditioning losses as low as possible and reduce unnecessary electrical energy consumption.
If you turn on the air conditioner for a long time, you should adjust the temperature from time to time to adjust it to a more suitable temperature range, such as adjusting it to 23-28 degrees Celsius, and you can save 10% of your electricity bill for every degree of temperature rise.
Refuse to "turn on and off the air conditioner frequently" to prevent the air conditioner from causing irreversible damage to the air conditioner and shorten the service life of the air conditioner.
2. Electric water heater
Summer is so hot that almost everyone has to take a shower every day.
However, the water heater has the function of keeping warm, so we can choose to "turn on the electric water heater 24 hours a day" or "temporarily use it temporarily" according to our habits.
However, no matter which option you choose, if you want to save electricity, it is best to pull the plug when not in use, not only because the standby mode will consume electricity, but also because after we set the electric water heater to a certain temperature, once the water temperature drops, the energized electric water heater will automatically heat up and heat the water to the set temperature.
To this end, I recommend that you do the following:
If you are traveling, traveling, or using less water, you should cut off the power as soon as possible and pull out the plug, which can save the consumption of electrical energy to the greatest extent, and can also reduce the pressure on the circuit and reduce the chance of accidents.
In addition, if there is a lot of water in summer and it is not suitable to cut off the power and pull the plug, we will adjust the temperature of the electric water heater to a more suitable range, such as around 40-45 degrees Celsius, which is not only energy-saving but also environmentally friendly and hygienic.
3. Refrigerator
The main function of a refrigerator is to keep it fresh and refrigerated.
In winter, this function is almost useless, so in many households, the refrigerator only works in July and August, when it is the hottest, and most of the time it is idle.
So, should I turn on the power when I am idle?
Many people feel that it is good to be energized and can prevent malfunctions.
But there are also people who hold the opposite opinion, such as netizen @小王's cat, she said:
Never mind! Unplugging to save power is "really useful"!
I would like to advise you to:
If you don't use it or have too few refrigerated items, unplug the refrigerator as soon as possible, so that it is not a problem to save hundreds of yuan in electricity bills a year.
4. TV set-top box
Small size, no power consumption?
This is the biggest misconception everyone has about TV set-top boxes.
Although it is inconspicuous, it is a veritable "electricity thief" and is ignored by many people.
According to the statistics:
In standby mode, the average TV set-top box consumes about 1-5 watts of electricity per day, and when watching programs, it will rise to about 10-20 watts.
In other words:
Even if the TV set-top box is "hibernating", the TV connected to it will still run at low power at a low power level so that it can respond quickly when it is turned on again.
As long as the TV set-top box is not plugged, it will always consume power and consume a lot of electricity.
On the other hand, we don't have to pay hundreds of dollars more for electricity every year only by turning off the power and unplugging it when we don't use it as soon as possible.
5. Rice cooker
We all use a rice cooker for three meals a day.
Many people think that such small household appliances definitely do not consume electricity.
But I don't know that even if I don't use it, the rice cooker still consumes about 50W of electricity.
This is because the rice cooker has an "auto-keep" setting, and when the temperature drops below 70 degrees Celsius, the rice cooker will automatically heat up.
And for a long time, it will not only consume electricity and money, but also accelerate the aging of the rice cooker line and shorten the service life of the rice cooker.
Of course, because of the high frequency of use of the rice cooker, if we keep pulling out the plug, it will inevitably accelerate the aging of the plug and take time, so you can try to change to the "plug with its own switch", and press the switch on the plug every time you don't need to use the rice cooker to cut off the power of the rice cooker.
Write at the end,
In addition to the above 4 kinds of household appliances, if other household appliances at home are not used often, it is best to unplug them, not only to save electricity and money, but also for the sake of safety, after all, the more household appliances, the greater the burden on the wires, and the easier it is to cause wire short circuits, trips, fires, etc.
