Recently, I suddenly found that the electricity bill at home is more than 300 yuan a month, which is very abnormal.
After all, most people have the impression that a family's electricity bill is only more than 100 yuan. My first reaction is whether something is broken? So we found the power meter and planned to conduct a round of test on the main electrical consumers. Through the test, we found the reason for the monthly electricity charge of more than 300 yuan. At the same time, we also shared some power saving tips.
Electric water heater: 24 hours, 4 kilowatt hours, 60 yuan per month
The electric water heater can be said to be a major power consumer at home. I personally conducted a one-day test, and the power consumption was about 4 degrees. It took 15 minutes to heat the 3000W electric water heater to 75 degrees, which is equivalent to heating 8 barrels of 60L water every day. In fact, most families use only 60L of hot water every day. So it is meaningful to choose an intelligent and power saving electric water heater for power saving.
Bedroom air conditioner 1: 8 hours, 4 kilowatt hours, 60 yuan per month
The air conditioner in the master bedroom should be on for at least 8 hours every day. According to the actual test results, the monthly cost should exceed 60 yuan. I think you can choose the air conditioner according to your own actual situation. There is no need to deliberately adjust the number of degrees, which is of little significance.
If you want to save electricity, the first is to choose a new level of energy efficiency products, the second is to open fewer windows and enhance the closeness of the room, so that you can save a lot of money.
600L refrigerator: 0.7 kilowatt hour electricity for 24 hours, 21 yuan per month
What surprised me was that the 600L refrigerator actually saved more electricity than the small refrigerator at home. According to the measured results, the refrigerator with Level 1 energy efficiency really saved more electricity.
As for the power saving skills of the refrigerator, I think the main thing is to choose the products with first-class energy efficiency, and the second thing is not to switch the refrigerator on and off too frequently.
300L refrigerator: one kilowatt hour for 24 hours, 30 yuan per month
The 300L refrigerator has been bought for a long time, and consumes about 1 kilowatt hour of electricity every day. Therefore, whether there is a relationship between power saving and capacity or not, from the measured results, it does not matter much for household products.
Bedroom air conditioner: 2 hours, 1 kilowatt hour, 30 yuan per month
The air conditioners in bedroom 2 and bedroom 1 are the same model, but they are rarely turned on. According to the estimate of 1 kilowatt hour per day, 30 yuan is needed per month.
Air conditioning in the living room: 6 kilowatt hours per 10 hours, 90 yuan per month
The air switch directly used by the living room air conditioner can not be directly connected to the tester for testing. It is open for about 10 hours every day. Compared with the bedroom air conditioner, the living room air conditioner has more power, so a conservative estimate was made. The monthly cost is 90 yuan based on the calculation of 6 degrees per 10 hours.
Electric lights, steam ovens, electric kettles, etc.: one kilowatt hour per 24 hours, 30 yuan per month
For other power consuming products, due to low power consumption and uncertain service time, it is estimated that 30 yuan will be charged per month based on one kilowatt hour per day.
Conclusion: It's not unfair to spend more than 300 yuan a month on electricity
From the actual test, it is really reasonable to spend more than 300 yuan a month on electricity. From the overall electricity consumption, the first thing that can be done to save electricity is to replace all household appliances with first-class energy efficiency products, which is expected to save more than 10% of the cost.
Secondly, if space allows, the two refrigerators can be replaced by a single large capacity refrigerator, which is expected to save about 5% of the electricity cost.
The other is to turn off the lights, turn on the air conditioner and close the windows. It is estimated that 5% of the electricity cost can be saved. It is estimated that about 60 yuan can be saved in one month.
