Modern households often opt for hot/cold water dispensers instead of instant water heaters because they conveniently provide hot water in winter and cold water in summer. They’re especially beneficial for those who enjoy tea, coffee, or instant noodles.
To maintain the desired water temperature, these dispensers typically operate at a power range of 700 – 1,200 W, depending on the manufacturer and capacity. If left plugged in continuously and used to heat around 6 – 8 liters of water per day, they can consume about 40–100 kWh each month. Unplugging your water dispenser at night not only saves energy but also reduces fire hazards.
4. Clothes Dryers
During the cold winter months and particularly in the humid rainy season in Northern Vietnam, most households rely on clothes dryers to keep laundry fresh and dry. However, these devices are energy-intensive.
For common models – whether vented or condenser types with an 8 kg capacity operating for 1 – 2 hours per use – the monthly consumption can range from 75–140 kWh if used daily. More advanced heat pump dryers, on the other hand, consume significantly less power.
5. Desktop Computers
Computers, including laptops and desktop PCs, are commonplace in many homes. Typical power consumption ranges from 35 to 450 W, while high-performance desktop setups can draw up to 1,000 W. According to Vietnam Electricity (EVN), the average desktop computer can consume over 70 kWh per month. To cut down on wasted energy, always unplug your computer when it’s not in use.
6. Televisions
Televisions are a staple in most households – typically one in the living room and sometimes additional units in bedrooms for convenience. However, because TVs often run 24 hours a day, they can contribute significantly to your electricity bill.
When you’re not watching TV, unplug it to conserve energy and improve safety.
By being mindful of these energy-consuming devices and making a habit of unplugging them after use, you can significantly reduce your electricity consumption and lower your monthly bills while also enhancing home safety.
