To calculate the cost of electricity for an induction stove, the direct basis is the power consumption of the induction stove, the higher the power, the higher the consumption. We usually know that electricity consumption is measured in kW/h (kilowatts, kilowatt-hours) and this is the parameter to calculate monthly electricity bills.
First, you need to understand the power consumption index of the stove (the parameters about the stove brand are clearly stated on the stove label, packaging when purchasing) and the actual cooking time on the stove in 1 month.
For example: a simple double induction stove with 2 cooking zones, each zone has a power of 2000W, the total power of the stove is 4000W, you cook 2 main meals a day with a total cooking time of 45 minutes and use both cooking zones at the highest power level.
Then, your cooking time in 1 month will be calculated as: 45 x 30 = 1350 minutes, equivalent to 22.5 hours, from which the electricity consumption of the stove is 22.5 x 4 = 90 kWh (or 90 kilowatt-hours), calculated at the highest price of the electricity supplier is 2,000 VND/1 kWh, we have 90 x 2 = 180 thousand VND.
This is the average level for a 4-person family with the highest electricity consumption in the electricity bill. So compared to a gas stove, it is definitely much cheaper because on average a 4-person family uses 1 gas cylinder per month – 350,000-400,000 VND. These are all qualitative actual data that families will certainly have changes.
Should you use an induction stove?
Are you wondering whether to buy an induction stove or not? With the increasingly modern life and modern technology electrical appliances bring convenience to users and are chosen by many people. Let’s analyze the advantages and disadvantages of induction stoves and the benefits of using induction stoves to make your own decision.
Advantages of induction stoves
Induction stoves work on the principle that when the stove starts operating, the current flows through the copper coil placed under the stove’s glass surface and generates a magnetic field within a few millimeters on the stove surface, thereby heating the pot with an induction base to cook the food.
- Time-saving cooking and power consumption
– Induction stoves have high power, they work on the principle of direct heating of cooking utensils without spreading heat energy to the surroundings, achieving efficiency of up to 90% so they have the ability to cook food quickly. The stove works well in air-conditioned rooms or places with strong winds, without being affected by the temperature. High efficiency consumes less so the stove will help you save energy.
– After a long working day, taking care of the family, you will have less time to take care of yourself and rest, but you can shorten the cooking time with an induction stove. With a high power, the principle of direct heating of the cooking utensils makes the cooking process faster, helping you save cooking time.
- High safety
– Induction stoves use a magnetic field based on the operating principle of the Foucault current to heat the cookware and then heat the food inside. Compared to other types of stoves like gas stoves, charcoal stoves, induction stoves are absolutely safe and good for health because they do not emit heat to the surrounding environment, do not cause fire or explosion, do not burn oxygen and do not release toxic gases CO and CO2 into the kitchen space.
– In addition, induction stoves do not affect the health of users… The electromagnetic waves emitted from the induction stove are very weak, ranging from 20kHz to 23kHz for heating. This wavelength is compared to the 2.4 GHz microwave wavelength. The stove surface almost does not have radiation because the intensity of the electromagnetic wave radiation emitted is very low. Therefore, the health of users and even pregnant women and the development of the fetus are not affected.
– Unlike gas stoves, induction stoves use tempered glass surfaces, usually imported induction stove brands use Schott Ceran glass, a type of completely insulated ceramic glass that can withstand heat well even during cooking, water spills on the surface of the stove, users can use a dry towel to wipe off the water on the surface without worrying about electric shock. And you no longer have to worry about gas leaks leading to explosions.
- Diverse in models and types
Accompanied by the current trend of induction stoves on the market with many different origins such as Germany, Spain, Italy, Malaysia, Vietnam… the diversity in origin, design and type, with cooking stoves, three-burner stoves, four-burner stoves and prices are very affordable with high, medium and low ranges to suit all families. You can easily choose a suitable induction stove for your family.
- Clean and easy to clean
Induction stove surfaces are made of materials such as Schott glass or Ceramic… they are durable, heat-resistant and easy to clean. You just need to use a warm cloth to gently wipe the stove surface to easily remove grease stains.
Disadvantages of induction stoves
– Induction stoves use electricity to operate. Therefore, to ensure good stove performance and long life, you must ensure stable power supply, low voltage can make it difficult to use.
Selective cookware: Induction stoves are quite selective with cookware, many cases where the induction stove does not recognize the pot, you will need to use suitable cookware. The stove can only be used with pots that have a magnetic induction base. When using the stove, you need to buy new pots with an induction base or heat transfer tools. So the living expenses of the family will increase, causing inconvenience to users.
Cooking interruption when power outage: This is something that users are concerned about when using induction stoves. If there is a power outage, the induction stove cannot be replaced by any other fuel. Unless your family has a generator. However, if the amount of electricity from the generator is too low to supply the induction stove, you will be interrupted in your cooking process.
Relatively high cost: Induction stoves have different price ranges. There are stoves that cost a few million VND, but there are also products that cost tens of million VND per unit. This is also one of the disadvantages of induction stoves that make many consumers worry when buying.
Above are some advantages and disadvantages of induction stoves. Depending on your usage needs and budget, you can choose an induction stove that suits you.
User reviews after using induction stoves
Child lock function
Ms. Mai: “Since the gas price went up, my family has switched from using gas stoves to induction stoves. On average, my monthly electricity bill is about 500,000 VND, including TV, refrigerator, air conditioner, washing machine, water pump, induction stove, lights, iron.
Previously, I used 1 gas cylinder for about 1.5 months, costing about 300,000-350,000 VND, but now using an induction stove costs only 100,000 VND in electricity bills, saving more than half of the money when using gas.”
Mr. Quang (Dong Lang, Hanoi) also highly appreciates the effectiveness of induction stoves: “My family uses a double induction stove and my wife said it’s also energy-saving, the electricity is 3,000 VND/kWh and the electricity bill is about 100-150,000 VND/month. It seems to save, and it doesn’t cause harm, fire, or explosion. I’m just worried about… power outages.”
Ms. Oanh – Dong Da – Hanoi: We bought a Dann IB626 BK induction stove from Bep Viet to use, the stove is very energy-efficient thanks to the inverter technology. Previously, I used a regular gas cylinder for about 1 month with a price of 350 thousand VND, but now I switch to using an induction stove and find that the electricity bill differs by 200 thousand VND compared to the months when I used a gas stove. The investment in an induction stove is not expensive at all and I enjoy cooking because I can turn on the fan and cook at the same time, I am very satisfied.
Tips to save electricity for induction stoves
When choosing to buy an induction stove, you should choose stoves with excellent power-saving technologies such as IC5 power tracking system, superior inverter technology… Typically exist in the stove brands: Bosch, Hafele, Chefs, Spelier, Cata, Abbka, TeKa…
Use suitable pots for induction stoves with flat and thick bases, do not use old pots with a convex or concave bottom because it will reduce the cooking efficiency of the induction stove.
Boil a reasonable amount of water in the pot to avoid wasting energy and remember to cover the pot to speed up the cooking process.
