Induction Cooker

The induction cooker is becoming increasingly popular as a replacement for traditional gas stoves. There are single hobs available, mainly used for hot pot dishes, while dual or triple hobs are fixed in the kitchen.

On average, a single hob consumes 85-95 units of electricity per month, while a dual hob consumes 170-190 units. The actual consumption depends on the power usage and the type of cooker.

Induction Cookers Consume a Significant Amount of Electricity

Electric Water Heater

Electric water heaters are commonly used in the northern provinces due to the climate. Most families use a 20-liter heater, which is sufficient for 2-4 people on a daily basis. For those who only turn it on before use, the average daily consumption is about 70-80 units. For families that keep it on continuously and use it frequently, the consumption can increase up to 230-340 units, according to EVN statistics.

Refrigerator

This can be considered the largest electricity-consuming appliance in households. It is constantly running, which is why even though the power capacity is not too high, it consumes the most electricity.

A small refrigerator with a capacity of 150 liters and a power capacity of 100-150W consumes about 4-5 kWh per day. Larger refrigerators consume even more electricity, about 6 kWh per day. This is a considerable power consumption for a household appliance.

Opening and closing the refrigerator multiple times a day causes it to run more, resulting in increased electricity consumption.

Rice Cooker

Rice Cookers Also Consume a Significant Amount of Electricity

Rice cookers are very popular appliances in households and are used daily. Many homemakers plug in the rice cooker early in the morning because they don’t have time to cook rice later.

This may seem simple, but it actually consumes more electricity than an air conditioner. The longer it is plugged in, the more electricity it consumes to heat up the rice. This can lead to wasted energy.

A rice cooker with a capacity of about 1.2 liters has a power capacity of 350-400W. If it is used for two hours, it will consume about 0.75 kWh. Larger rice cookers will consume even more electricity.

Desktop and Laptop Computers

Desktop and laptop computers still run in the background even when you have turned them off. On average, these devices consume about 96W per day.

That means each computer in the house consumes about 3 units of electricity per month for no reason. This number can increase up to 15 times if you have the habit of putting your computer to sleep mode.

Clothes Dryer

Clothes dryers are becoming more popular in Vietnam due to their time-saving and convenience, especially on rainy or humid days. The most common type is the air vented or condenser dryer with an 8kg capacity. The drying time varies from 1-2 hours, depending on the mode, and consumes 75-140 units of electricity per month if used daily. With more advanced heat pump dryers, the energy consumption will be much lower.

Frequently asked questions

The electricity consumption of an induction cooker varies depending on the number of hobs and usage. A single hob typically consumes 85-95 units of electricity per month, while a dual hob can use up to 170-190 units. The more hobs and the higher the power usage, the greater the electricity consumption.

While induction cookers are known for their efficiency, electric water heaters and rice cookers are also energy-intensive appliances. The climate in the northern provinces often dictates the use of electric water heaters, with a 20-liter heater being sufficient for daily use. Rice cookers, despite their small size, can consume more energy than an air conditioner if left plugged in for extended periods.

Refrigerators are the largest electricity consumers in households due to their constant operation. A small refrigerator with a capacity of 150 liters can consume about 4-5 kWh per day, while larger models use up to 6 kWh. To reduce consumption, avoid opening and closing the refrigerator frequently, as this increases running time and electricity usage.

Rice cookers, desktop and laptop computers, and clothes dryers are all notable energy consumers. Rice cookers with a capacity of 1.2 liters can have a power capacity of 350-400W, resulting in significant energy usage if used for extended periods. Computers, even when turned off, consume an average of 96W per day, and this can increase if they are left in sleep mode. Clothes dryers, especially the air vented or condenser type, can use up to 140 units of electricity per month.
