Hot and cold water heater
The hot and cold water heater is one of the electrical appliances that is used daily, and its power can reach up to 3000w. Due to its high frequency of use, if the heater is left on all day, it can consume about 20 times the amount of electricity.
In the summer, you may not need hot water, but don’t forget to turn off the switch when not in use. When you need to use it, just turn it on 30 minutes before taking a shower. When the temperature on the indicator reaches the appropriate temperature, turn it off. This can save a lot of electricity.
Air conditioner
The air conditioner is not the device with the largest power in the household, but it consumes the most electricity due to its high usage, especially during hot weather. Many families have a habit of keeping the air conditioner on almost all year round. On extremely cold days, they switch from cool mode to warm mode. To save electricity, regular maintenance is needed for the air conditioner and ensure good insulation for the house, maintaining a reasonable temperature and minimizing opening and closing doors when the air conditioner is on…
Cooling fan
A regular cooling fan has a power of 80 – 200W. If you turn it on for 6 hours a day, it will consume about 0.48 kWh to 1.2 kWh.
A regular electric fan has a power of about 40W. If you turn it on for 5 hours a day at the highest speed, you will have to pay for 2 additional electricity units per month compared to running the fan at the lowest level.
Television
Many people think that the electricity consumption of a television is not much because its power is quite small. However, in reality, a 32-inch television has a power of about 40W. If it is continuously turned on day and night, it can consume a lot of electricity. Even when the TV is not in use but still plugged in, it can cost your family an additional 500,000 VND in electricity bills per year.
Computer
Computers (both desktop and laptop) still operate in the background even when you have turned them off. These devices consume about 96W per day. So, every month, you will spend 3 additional electricity units for each computer. If you have a habit of keeping the computer in the “sleep” mode, this number will increase several times.
To save electricity, turn off the power and unplug the computer when you are not using it.
Rice cooker
This appliance does not consume much electricity, but the way it is used makes it contribute to an increase in electricity bills. Many people start cooking rice early and leave it for a few hours, even after finishing the meal, they keep it plugged in to keep it warm. This is a wasteful habit because a 1.2-liter rice cooker usually has a power of 350-400W. If it operates for two hours, it will consume about 0.75 kWh of electricity.
Devices that are not unplugged
There are devices silently consuming electricity in the house, eating up a significant portion of the family’s budget without you noticing.
Normally, you spend most of your time at work and not frequently at home. During that time, all electrical devices in the house are turned off, but why is the electricity bill still high?
For frequently used electrical devices, we usually just turn off the switch, but we don’t know that turning off the switch only puts the device into standby mode. If the plug is not unplugged, the device will still run. From there, they will silently consume a lot of electricity, gradually increasing your electricity bill.
These are energy-consuming devices even when they are turned off thanks to “phantom power”. For example, washing machines, dryers, desktop computers, Wi-Fi routers, and televisions.
Limit this energy consumption by unplugging the devices from the power outlet. Another convenient way is to plug these devices into a shared power strip so that you can turn off all connected outlets with just one plug.
