Controls that are directly responsible for adjusting the power of the burners. At the same time, other control elements can be provided in the design. For example, rotary knobs are often combined with buttons, to which additional functions are designated.

— Rotary knobs. The traditional, most common option, found in hobs of all types — both gas and electric — and price categories. Rotary knobs are quite convenient and functional while being simple in design and inexpensive.

— Pop out knobs. A variation on the rotary knobs described above, in which the control knobs can be recessed into the control panel. The specific design may be different: in some models, the handle is recessed during operation; in others, it remains recessed until the corresponding burner is in use and pops out from the panel during operation. This design gives the hob a neat appearance, reduces the number of places where dirt can accumulate, and makes the front panel easier to clean. Unlike rotary knobs, pop out knobs are mainly used in electrical models.

— Touch controls. Touch controls are found only in electric hobs. This option has several advantages. First, the touch controls look neat and have no protruding parts, making them easy to clean. Secondly, the control is carried out with light touches and req...uires minimal effort. Thirdly, touch controls give the stove a stylish and technological appearance. On the other hand, such stoves are quite expensive and may be inconvenient for some users who are accustomed to traditional rotary knobs. Therefore, relatively few touch control models are produced. Usually, it is compact hobs for 1 – 2 burners without an oven, where rotary knobs would not be very appropriate.

— Slider. A kind of touch control represented by sensitive tracks. 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 also lies in the fact that you can immediately set the required heating power by clicking on a certain area of the scale.


— Push-buttons. Control, carried out exclusively with the help of buttons, is used very rarely in modern stoves. Most models with such controls are compact portable stoves for one or two burners: it is not always convenient to equip such devices with rotary knobs, but the buttons fit well into the design. They are also cheaper than touch controls. On the other hand, the price difference is not so great, and the buttons are somewhat less convenient to use and clean — mainly for this reason they are noticeably less common.

— Enamel. Enamel coating is inexpensive and relatively easy to clean. In addition, enamel can have different colours, which allows you to give the stoves an original appearance (although the most popular is still the classic white colour). On the other hand, cracks, chips and scratches may appear on such a surface. As a result, such a coating is typical for relatively inexpensive boards.

— Stainless steel. Steel hobs are highly durable and attractive. But, it will take a lot of effort to keep such a stove clean: even slight dirt is noticeable on a steel surface (especially polished). And it is more difficult to clean them than enamel. In addition, such surfaces are somewhat more expensive than enamelled ones, and there are, in fact, two design options for them - matte and polished.

- Glass-ceramic. A material is found predominantly in electric stoves; rarely used in gas models, mainly for aesthetic reasons. The main advantages of glass ceramic are resistance to heat and high permeability to heat and electromagnetic radiation. Schott Ceram and EuroKera, manufacturers of this very glass-ceramic, which manufacturers of household appliances install in their models, were especially successful in this. It allows electric burners (regardless of type) to be placed directly under such a surface. The re...sult is a flat top with no protrusions, making cleaning easier and providing a neat appearance. The main disadvantages of this material are high cost and sensitivity to impacts.

- Tempered glass. A material similar to the glass-ceramics described above: the glass surfaces have an attractive appearance, usually with a glossy finish. Another common feature is the ease of cleaning: most of the contaminants are easily removed. However, this material is not as strong as glass-ceramic: it is much more sensitive to impacts and tolerates heat much worse, which makes it poorly suited for installation above burners. As a result, tempered glass is used mainly in gas stoves, where the burners are located above the work surface and tempered glass heats up relatively weakly. Another category of stoves with such a surface is electric models with induction hobs, where the dishes and not the surface are mainly heated (see below for more details).

— Plastic. Working surface made of special heat-resistant plastic. A rather specific option is found mainly among portable single-burner electric stoves with induction heaters (see below). There are several reasons for this. One of them is that, despite the heat resistance, even fairly advanced plastic does not tolerate heating on gas or a classic electric burner. But with an induction burner, this material works without problems, especially since it is well permeable to electromagnetic radiation. Plastic is cheaper than tempered glass or glass-ceramic, and it also weighs less - the latter is important for a stove that is planned to be moved frequently from place to place. At the same time, all these advantages cannot be called critical. As a result, this option, even in its niche, has not received much popularity.

The number of solid plates in the design of the stove.

Solid plate hobs are the simplest type of electric hobs (see Hob type). Such a burner has the appearance of a "pancake" raised above the hob. The main advantages of such burners are the simplicity of design and low cost. On the other hand, they heat up slowly and have high thermal inertia — they react with a great delay in heating power adjustment. Another disadvantage is that solid plates can deform over time. After 2-3 years such a burner may need to be replaced. As a result, solid plate burners are typical for low-cost electric stoves, as well as, combined models, where the electric heater is a spare. But the variety can include both 1-burner stoves and 2-burner stoves.

The number of induction burners in the stove design.

Induction burners work due to electromagnetic radiation, which creates special currents in the bottom of the cookware — these currents provide heating. At the same time, the burners do not heat up — they are heated only by the heat from the dishes, so this type of heater is the safest. Another advantage is that the burners react instantly to a change in heating power — as in gas stoves. On the other hand, induction heaters are quite expensive and have specific requirements for cookware: for effective heating, it must have a thick metal bottom. However, a lot of dishes these days are being produced and created based on the possibility of working with such burners. And the variety of stoves starts with models with 1 burner(portable devices without an oven).

Rated burner power. This parameter allows you to estimate how much electricity the burner will spend when operating at maximum heating intensity. At the same time, the heat transfer power of different burners can be different, and the actual heating efficiency will also greatly depend on the specs of the dishes. As a result, it hardly makes sense to evaluate the operating capabilities of the stove by the power of the burners. It is quite possible to proceed from the fact that the burner will be enough for a dish of the same diameter.

The type of automatic switch-off provided in the design of the stove.

Auto-off can be provided for the hob(hob), for the oven, or for both at once, regardless of whether the hob and oven are gas or electric. This function is implemented through a timer, after which the device turns off.

A display on the stove control panel. Usually, it is a very simple one-colour display : 3-4 digits plus a few additional characters (for example, a thermometer icon and a clock icon). However, even on such a display, almost all important information related to the stove operation can be displayed: heating temperature, clock, timer settings, and other relevant data. Thus, the display significantly simplifies the management of the stove and makes it more convenient.

For technical reasons, this function is mainly used in electric stoves; there are also gas models with displays, but they are extremely few.

The connected load of the stove is the maximum electrical power consumed during operation. This parameter is indicated only for models that are equipped with at least one electric heater — burner (burners), oven or grill. It is the burners that are the highest consumption in terms of energy consumption; Features such as auto-ignition or oven lighting require little energy, a ordinary socket is enough for them.

First of all, the requirements for the power grid depend on this indicator: it must be able to provide such power without overload. 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 stove to a 230 V network according to special rules. An alternative is a three-phase 400 V mains: most modern stoves with electric heaters allow connection to both 230 V and 400 V.
