6 Energy-Guzzling Appliances That Out-Consume Air Conditioners: Unplug Them After Use or Face Skyrocketing Bills

1. Induction Cookers & Electric Stoves

In today’s modern era, induction cookers or electric stoves are indispensable in every household. However, despite being safer than gas stoves—which carry a higher risk of fire and explosion—they are notorious for their high electricity consumption.

For safety and energy savings, always unplug your induction cooker or electric stove after use. Experts warn that if you leave an induction cooker continuously plugged in—even when it’s not actively in use—a single-burner model can consume about 85–95 kWh per month, while a double-burner model can reach 170–190 kWh. The exact consumption depends on the power rating and type of cooker. Unplugging after use is a simple way to cut unnecessary energy costs.

2. Water Heaters

Water heaters are essential during the coldest days, especially in winter. In Northern Vietnam, many families use 30-liter water heaters—sufficient for 2–4 people daily—but these appliances consume a significant amount of electricity, often even more than air conditioners.

For households that operate the water heater only when needed (around one hour a day), the consumption is roughly 70–80 kWh per month. However, for those that leave it running continuously or use it heavily, consumption can soar to 230–340 kWh monthly. To ensure safety and reduce costs, remember to switch off the circuit (or power) and unplug the water heater after use.

3. Hot/Cold Water Dispensers

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.
