What is an induction heating stove?
The induction hob design is significantly different from conventional gas or electric hobs. The difference lies in the operation of the heating elements. A special feature of the device is the absence of a spiral, which was heated by the passage of electrical or thermal energy.
The induction hob design is significantly different from conventional gas or electric hobs.
Heating occurs through the formation of a powerful bunch of electromagnetic waves, which propagate through the metal and stimulate heating processes. The resulting heat is transferred to the dishes and food. This approach allows you to intelligently use energy for its intended purpose, which allows you to save significantly.

Heating Induction Cooker
An induction cooker for cooking is a device that has a completely different heating principle. It does not contain a heating coil. Instead, it uses a high-frequency magnetic field to excite induced currents in the metal surface. The flow of these currents is already doing useful work, heating the dishes, and with it the food. Therefore, the induction cooker uses power for its intended purpose.
Not all cookware is suitable for use on induction cookers. It must have magnetic permeability and a certain resistivity value, otherwise the oven simply will not work. Steel is most suitable for these purposes.
Design and principle of operation
To understand how much electricity an induction cooker consumes, you need to understand its structure and operating principles. Due to the special heating method, the device gained popularity in the market in a fairly short time. The heating process occurs by transmitting magnetic pulses generated by an electromagnetic field. It, in turn, arises through the passage of electric current.
To understand how much electricity an induction cooker consumes, you need to understand its structure and operating principles.
Traditionally, the heating surface of such a device consists of the following structural elements:
- control panels;
- main part (body);
- power plants;
- temperature sensor.
The peculiarity of this design is that the heating pulse is directed. This means that energy is not dissipated, but only heats the food in the pan. The surrounding objects remain cold.
Additional Information. This is a great option if you have a small child. Now he will not get burned by accident if he touches the surface of the stove. You no longer need to keep dangerous matches in your house.
Note! If you use an induction cooker, you will have to purchase new cookware. They must have the required magnetic penetration coefficient. The best option is ferromagnetic products.
Another innovative solution is that there is no need to install a heating coil. This approach reduced the amount of energy and increased system reliability.

The tile is a cooking surface in the form of a transformer. The induction coil is located immediately below it. The second element for the operation of the electromagnetic field will be the dishes that you place on the surface.
The second element for the operation of the electromagnetic field will be the dishes that you place on the surface.
The device is constantly connected to the network. Heating occurs only at the moment when the corresponding container is placed on the burner. The principle of operation is as follows - alternating current passes through the coil and forms an electromagnetic field, which is transmitted to the bottom of the dish. Under its influence, the surface begins to heat up to the desired temperature. Food is cooked using heat currents that are spread by a heating magnetic field.
Food is cooked using heat currents that are spread by a heating magnetic field.
This method is characterized by low energy consumption. All heat is directed exclusively to the target container, allowing you to cook food much faster. At the same time, the power of induction cookers in kW is 3.5, which is much lower than that of conventional gas or electric appliances.

Why is an induction cooker energy efficient?
Firstly, an induction cooker does not require 20-30 minutes of heating, like a classic electric cooker. Calculate how many precious watts you will thus save per year in the departmental canteen.
Secondly, the efficiency of an induction cooker is more than one and a half times higher than that of an electric cooker. The first converts electrical energy into heat with an efficiency of 90 percent, and the second with an efficiency of 55 percent!
Thirdly, an induction cooker consumes electricity discretely. That is, if necessary, the “gluttony” of the equipment is reduced, as are your electricity bills. Not a single classic electric stove can boast of this, since it turns on in the morning, works throughout the day and turns off only at the end of work, consuming a very large amount of electricity.
Fourthly, you can cook dishes on an induction stove faster than on a regular electric one. For example, under all equal conditions, 2 liters of water boil on an induction stove in 5.5 minutes, and on a classic electric stove - in 30 minutes, including heating the stove itself.
Fifthly, with an induction cooker you will reduce the cost of additional air conditioning in the kitchen. This stove hardly heats the air, unlike a regular one, so the temperature in the “induction kitchen” is quite comfortable.
Sixth, according to reviews from restaurant owners, after switching to induction cookers, their electricity costs decreased by 20-30% .
Energy consumption and power of an induction hob
Knowing the principle of operation, you can determine how much electricity an induction cooker consumes. This indicator depends on the design features of each manufacturer’s devices. If we name the average indicator, then it should not exceed two kW per hour for one burner. To many, this figure may seem quite large. Moreover, most stoves have from two to four burners. That is, electricity consumption, at first glance, is quite high. Let's figure out how you can save money with such a device.
Knowing the principle of operation, you can determine how much electricity an induction cooker consumes.
In terms of productivity, the efficiency of an induction cooker reaches ninety percent. This result can be achieved by directed heating of the surface of the cookware. This makes it possible to heat food or water much faster than on other types of stoves, which indicates high energy levels.
This makes it possible to heat food or water much faster than on other types of stoves, which indicates high energy levels.
For example, if you heat water on an induction stove, you will spend six minutes on it, but on a regular stove it will take up to thirty. This is a significant difference. Now you can evaluate how beneficial it is to use induction panels. They allow you to reduce cooking time by almost five times. If you know how much energy your induction cooker uses, you can save a lot of money on your energy bills.

How much energy does the stove use?
@youtube.com “Work not Work”
Consumption depends primarily on the manufacturer of household appliances; different manufacturers supply their products with different indicator sizes. On average, one burner consumes up to 2 kW per hour. Due to the induction method, electricity consumption is several times lower than analogues using a different method.
Example! It took 5 minutes to boil 2 liters of water, the electricity consumption was 0.35 kW/hour, which is five times more efficient than an electric stove
The more burners on the stove are used, the higher the consumption. With high power, the cooking process takes less time than on an electric or gas stove.
A convenient feature of this type of panel is the display of the power expended after the end of cooking. If you keep track of your consumption expenses, this feature comes in handy.
Advantages and disadvantages of induction hobs
Based on the above, we can highlight the following advantages of induction cookers:
- high cooking speed;
- the panel can be built into the design of a regular table;
- characterized by a high heating rate of the working surface;
- the presence of dishes on the surface is determined automatically due to sensors built into the device;
- heating is directed exclusively at the dishes and contents - all other objects nearby remain cold;
- any model of induction cooker is characterized by high efficiency, so you should not look at the power indicators of equipment from different manufacturers;
- a wide range of different functions, which allows you to significantly simplify the cooking process and realize many culinary ideas;
- ease of maintenance - the surface is very easy to clean with special products;
- safety - you definitely won’t get burned or injured, there is no chance of a fire;
- modern and simple design that will fit into any interior and become its decoration;
- power increases or decreases smoothly in automatic mode, which occurs thanks to installed sensors.
Despite the fact that induction cookers are innovative equipment with many advantages, you should be aware of some of their disadvantages:
- You can only use special utensils made of ferromagnetic materials;
- The cooling system makes a lot of noise during operation, which can be disturbing.

Ways to save costs
Despite the high energy consumption of this equipment, the consumer has several ways to save costs:
- cook dishes in dishes with a flat bottom, increasing the area of contact with the burner;
- use pots and other containers that do not extend beyond the burners;
- to prepare dishes that require a long time, use a pressure cooker;
- cover the pans with a lid, which reduces the boiling time of the liquid;
- turn off the stove shortly before the end of cooking in order to use the heating of the burner without power supply;
- replace the heating element model with a more modern one. Halogen ones consume up to 20 percent less, due to increased efficiency and reduced time for heating dishes. You can save 40 percent when using an induction model, but in this case you will need special cookware made of a ferromagnetic steel alloy.
We recommend: Electric meter plugs
As you can see, an electric stove is not the most economical consumer of energy resources. But the user can reduce consumption using the specified equipment.
Differences between induction and electric cooker
Let's figure out how different the equipment is. The main difference between the devices is the principle of their operation. The electric stove first heats up, after which the dishes and food are heated. An induction cooker only heats the cookware, but remains cold.
An induction cooker only heats the cookware, but remains cold.
For an electric device, the type of cookware does not matter, but for an induction panel you will have to use special kitchen utensils. In this case, the second option is safer, since the surface remains completely cold. Also, the induction cooker heats up exactly as much as necessary so as not to overuse energy. This is a more economical solution with many advantages.

Disadvantages of induction cookers:
Only special utensils with magnetic properties are used. These are dishes made of stainless steel, aluminum with a ferromagnetic bottom, cast iron cookware. But utensils made of copper, brass, aluminum, heat-resistant glass and other non-magnetic materials are not suitable for such a stove. As a rule, accessories suitable for “induction” are marked with a special pictogram. But progress cannot be stopped. There are already induction cookers that can use any metal cookware, and devices are also appearing that allow you to cook a product in copper and aluminum cookware on an induction cooker. When working on induction equipment, careful handling of the glass-ceramic surface is necessary. Although it has high strength, it is afraid of a sharp point blow. This dictates a certain work culture. Induction cookers are high-tech equipment with built-in electronic components. Therefore, it is necessary to prevent water and contaminated air from entering the housing.
Electricity consumption of electric stove burners
Depending on the size, the cooking mode and energy consumption differ:
- small – power does not exceed 1 kW, which is suitable for slow cooking;
- medium – power reaches 2 kW, which allows you to prepare soups and other dishes;
- powerful - power reaches 3 kW, intended for large containers.

Energy consumption of electric stoves
The power of the stove (the number of kilowatts consumed per hour) is:
- for burners - depending on the diameter, from 1 to 2 kW;
- for ovens - about 1.8 kW (with upper and lower heating elements). If there is a grill, the figure doubles.
Consumption of different types of stoves
Consider an electric stove with the power:
- 1.5 kW for burners with a diameter of 180 mm;
- 0.8 and 1 kW for the lower and upper heating elements of the oven, respectively.
The volume of electrical energy consumption will be:
For one hour: with simultaneous operation of two burners - 3 kW-h and oven - 1.8 kW-h;
We recommend: Until what date should meter readings be submitted?
Per day when using the unit in the above mode for two hours: up to 9.6 kWh;
Per month: up to 288 kWh.
Taking in the above calculation the average cost of one kilowatt-hour of 3 rubles, the amount for the month will be: 864 rubles.
The cost of tariffs for one kilowatt-hour of electricity varies by region. But for apartments equipped with electric stoves, prices are approximately 20% lower than for gasified housing.
