The number of induction burners in the design of the hob.

A feature of such a burner is that it does not heat up by itself but transfers energy to the dishes using electromagnetic radiation. This radiation is safe for humans, and at the bottom of the dishes, it creates currents, providing heating. This format of operation provides several advantages over traditional heaters. Firstly, the burner instantly responds to a change in the operating mode — in this respect, induction heaters are similar to gas ones. Secondly, the surface of the hob (usually glass or glass-ceramic) practically does not heat up — except that part of the heat is transferred from the heated dishes; this has a positive effect on safety. Thirdly, induction burners are quite economical in terms of energy consumption. Among the disadvantages of induction heating, in addition to the high cost, we can mention that it only works with dishes made of thick steel or cast iron. Other metals on such a burner will heat up weakly, and glass, ceramics and other non-magnetic materials will not heat up at all. However, a lot of modern cookware is created specifically for compatibility with induction, which often has a corresponding designation on the bottom.

Special zones on the surface of the hob suggesting the possibility of using dishes of non-standard shapes and sizes. The FlexZone consists of several induction heating zones under a single glass-ceramic substrate, which are activated depending on the size of the installed cookware. Hobs with an adaptive zone automatically recognize the presence of objects, and the simultaneous use of different types of dishes in this zone is also allowed.

A function that allows you to combine two (or more) adjacent electric hotplates into one burner. Often, this mode is found in induction hobs, less often in Hi-Light, and is not used in gas hobs. Often the "bridge" looks like one continuous heater of an elongated shape, the individual parts of which can be turned on independently and are separate burners. Anyway, the bridge mode (Bridge) can be useful primarily for working with elongated utensils — for example, goose roasters. In addition, the design may provide various additional functions — for example, the ability to set different power settings for different parts of the "bridge" and move the dishes between them depending on the readiness of the dish. At the same time, unlike conventional burners, the heating will turn on automatically, according to the presence of dishes on the burner.

The type of control used in the hob. The options might be:

— Rotary knobs. Control based on classic rotary knobs. Sometimes buttons are also provided in the design but they are only responsible for the additional functions of the device. It is the knobs that control the switching on and power of the burners (and the combination of knobs and youch controls is indicated separately — see below). This type of control is known for its simplicity, convenience, reliability and low cost, which make it extremely popular — it is used in most modern hobs of an independent type (see above).

— Touch controls. touch controls can control almost all functions of the hob, while the set of such functions can be very extensive. Among the advantages of touch sensors, one can note a stylish appearance, ease of cleaning due to the absence of protruding parts, and the touch controls do not need to be pressed — a light touch is enough. The main disadvantage of this type of control is its high cost, but it is mainly used in high-end hobs, where the price of touch controls is almost invisible compared to the cost of the entire device.

— Rotary knobs + touch controls. Combination of rotary knobs (see above) with touch controls. Note that only rotary knobs are enough for basic control of the burners, and buttons can also be used for additional functions — they are cheaper than touch controls. Therefore, t...his type of control usually means that we have a rather expensive model with an abundance of additional functions. Among the advantages of touch controls, one can note a neat and stylish appearance, as well as ease of cleaning — they, unlike buttons, do not have slots and protruding parts where dirt can accumulate. And some models with similar controls have a rather unusual design — for example, only one rotary knob, the purpose of which is changed by commands from the touch controls.

— Touch + magnetic disk. Touch controls (see above), supplemented by a special rotary control — a magnetic disk. This disc is somewhat similar to rotary knobs, but it is called magnetic because of the fastening — with a permanent magnet, which allows you to remove the control. Most often, there is one disc for all burners; less often there are models with their disc for each burner. However, such a regulator has two key differences from rotary knobs. Firstly, the magnetic disk controls not only the power but most of the other functions of the hob. Secondly, the discs look neater and are more comfortable to use: they spin easily, and the detachable design makes them easy to clean and keeps children out of the way. However, it makes sense to use this control method mainly in high-end hobs with an abundance of functions.

— On the oven. As the name implies, such hobs do not have their control — it is carried out from the oven control panel to which the device is connected. This variant, by definition, only occurs in dependent models (see "Type").

— Slider. A kind of touch controls. Often they are elongated in a slender line; less often they are made in the shape of a circle. To adjust the heating intensity of the burners or quickly access other settings of the hob, slide your finger along the corresponding touch scale to the selected value. The convenience of slider control is that you can immediately set the required heating power by clicking on a certain area of the scale.

— Separate. Control using sensors or sliders (see the corresponding paragraphs), which implies the ability to fine-tune the operation of the burners individually - each of them has its own power adjustment scale. Separate control allows you to set the required heating level for a specific zone without having to first select a specific burner by tapping on the panel. It is more intuitive and gives you more flexibility when preparing different dishes overnight.

The number of temperature settings of the burner. The more power levels, the more accurately you can set the required temperature for cooking a particular dish. However, in most cases, nine levels are enough for home use. But, if you are a gourmet and often cook unusual dishes that require strict adherence to the recipe, then you simply need more temperature settings.

— Boil detection. A system based on a sensor that monitors the state of the product being cooked (usually by the temperature of the dishes): before the water boils, the burner operates at maximum, and after boiling, the sensor reduces the intensity of work to a certain value. The point of this adjustment is that much less heat is needed to maintain the boil than to heat it up to the boiling point; moreover, if you do not reduce the heat, the liquid can spill. Accordingly, automatic boiling allows not only to save energy but also to avoid such troubles. This function is found in electric models (see Product type).

— Keep warm function. The keep warm function keeps food warm until served. It will come in handy in cases where dinner is already cooked and the guests have not yet arrived. The maximum time for keeping heat usually does not exceed 1-2 hours.

— Melting. Special mode for low-temperature thawing of small portions of frozen food, melting butter or chocolate. The function allows you to carefully melt the necessary ingredients into a mass of a homogeneous structure without fear that they will burn or overheat.

— Auto fry function. The pre-set automatic frying mode, which ensures that the temperature of the bottom of the dishes is maintained at the optimum temperature, preventing it from cooling down or over...heating. An auto fry programme usually provides several cooking modes for different tasks.

— Additional. Several specific auto-programmes used in individual hobs and not covered by the list above.

The input power of the hob is the maximum electric power consumed during its operation. This parameter is indicated only for models that are equipped with at least one electric hotplate. It is electric burners that are the highest consumption in terms of energy consumption. Additional functions such as auto-ignition require little energy, and a regular outlet is enough for them.

First of all, the requirements for the power mains depend on this parameter: it must be able to provide such power without overloads. It is worth noting that for household sockets the power limit is about 3 – 3.5 kW, with more power, you need to connect the hob to 230 V mains according to special rules. An alternative is to use a three-phase 400 V mains: most modern hobs with electric burners allow connection to both 230 V and 400 V mains.
