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.

Standard power parameters
A hob equipped with a pair of cast iron heating components usually has this parameter - 2000 W. How much in technology for a large family? The 4-burner version has a rating of 5000 W. If this version has induction operation, then the parameter can reach 10400 W.
The more heating components and other functional options a stove has, the more energy it consumes.
When choosing equipment, you should take into account that the power of the stove is affected by the heating dynamics of the burners.
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.

Types of stoves and calculation of their energy consumption
The degree of energy consumption of such a device is directly determined by its type. Today, two categories of slabs are common:
- Classic. In it, the surface is heated by conventional heating elements.
- Induction. Heating here is carried out due to the induction of vortex flows, which are formed by a high-frequency magnetic field. Its range: 20 – 100 kHz.
There are also combined versions. In them, some burners are equipped with heating elements, while others operate using the induction method.
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.

Energy consumption categories
Every manufacturing company wants to be competitive and produce devices that consume less electricity. And stoves, like other appliances, belong to certain classes of electricity absorption. Categories are designated by the letters A, B, C ... G. They start from the highest designation. Today the following variations are often found: A++ and even A+++. This indicates that consumption parameters exceed category A.
The category is affected by the amount of electricity absorbed when the specified temperatures are reached. The largest volumes are consumed when the oven is operating. But if this compartment is well insulated, heat loss can be reduced, and this will result in significant savings.
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.

Induction modifications
A separate position among stoves is occupied by models with induction heaters. They have serious power, and accordingly, the price. When used correctly, you can save on electricity costs. The reasons for this are the following:
- High heating rate.
- Automatically switches off the heating when the cookware is removed from the burner.
- Utensils are used that eliminate heat loss.
Induction devices operate using innovative technology - it is not the burner itself that heats up, but the bottom of the cookware placed on it. It heats up the work area, but to a maximum of 60 degrees. In this case, the culinary process occurs much faster. Heat losses are minimal, and the glass-ceramic surface does not transfer heat to the air in the room. As already noted, with proper operation, induction modification can become very economical. But in general it consumes large amounts of energy.
And if it has four burners, the cost is about 7 kilowatts of electricity. But this is a waste only when all burners are turned on at the same time, and only if they work at maximum. This phenomenon occurs very rarely. Typically, this need arises when you need to quickly prepare very large amounts of food.
Typically, users do not turn the burner to maximum; values from 6 to 8 are quite enough. And for simple heating, 3-5 is enough. For this reason, electricity consumption is much more modest. The induction device also heats up water and food twice as fast, similar to a conventional model. The faster the heating, the greater the savings.
The indicators for the burners are as follows:
Two have a diameter of 16 cm. Each consumes 1500 W. The diameter of the middle burner is 18 cm. It absorbs 2000 W per month. The diameter of the large burner is 3 cm larger than that of the medium one. She also eats 2000 W. The total is 7 kW.
Typically, users use a couple of small burners. Before designing the electrical system and making connections in your home, consider the maximum electricity consumption of the induction device.
Such plates are in great demand today. Many people like their technology and benefits. However, there are also skeptics. They are guided by the following prejudices:
- Serious harm to health from the magnetic field. According to the study, the field voltage of the stove is 90 times lower than that of an ordinary hair dryer.
- For induction modification, you need to purchase special cookware for a lot of money. In practice this is not the case. And many already outdated pans, coated with enamel and made of aluminum, have ferromagnetic qualities, which only has a positive effect on the induction process and energy saving. As a test, you can just place a magnet at the bottom of the container. If it sticks, then it's good.
- All metal objects become hot on the glass-ceramic surface. In reality, there are a number of technologies that protect against this. The main principle here is this: without cookware, there is no induction.
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.

Which stove is more economical?
Everything is simple here: induction models are characterized by instant heating and similar cooling - if the current is turned off, the induction coils do not produce a magnetic flux, and there is no heating of the bottom of the pan. When the user adjusts the temperature, its change occurs instantly - there is no need to wait until the burner warms up or cools down, since it is the cookware that is heated, and not the surface of the burner, which is limited to red on the panel.
Therefore, the conclusion is quite simple: electrical energy is consumed more rationally by induction panels, so paying bills is much lower. These models are considered much more economical; for comparison, electric ones use 1.5 times more energy.
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.

Criteria for choosing an economical stove
When starting to choose an induction electric furnace, they begin by determining the number of burners. Some approximate calculations will help you get your bearings:
- for a family of 5 people or more, models with 4 burners are suitable; the total power of such an electric hob is about 7 kW;
- for a family of 3-4 people it is convenient to use 3 burners;
- For a couple without children or one person, a stove with 2 burners is enough.
When choosing, pay attention to the functional equipment of the device, because each additional option increases energy consumption. Therefore, before purchasing, it is important to consider whether a touch screen, PowerBoost express heating and other additional features will be needed.
It is better to choose a device with energy-saving modes and protection against electric shock.
