Hob type
The type of hob provided in the stove.
The hob is the main working part of the stove, its top part, where the burners are located. The type of such a hob depends on the type of burners:
— Gas.
Gas burners are convenient, first of all, with an instant reaction to turning the power regulator knob. In addition, dishes made of any materials and with any shape of the bottom are suitable for them — provided that they normally tolerate heat and stand stably on the grates. In addition, in operation, such stoves are cheaper than electric ones. Their main disadvantage is the need to connect gas. Firstly, gas pipelines are far from being everywhere; and using interchangeable gas cylinders is a rather troublesome business. Secondly, the connection requires carefulness — it must be carried out by a gas specialist. Also, note that gas burners are more demanding on compliance with safety rules than electric ones.

Electric. Electric hobs are safe and easy to use: there are no open flames that need to be ignited and can go out, causing a gas leak. In such devices, it is easier to implement various additional functions than in gas stoves. In addition, electricity is available in any home, unlike gas. And the connection procedure is quite simple (although it may also require the participation of a specialist). On the other hand, electric hobs have high energy consumption. Therefore, they requir
...e high-quality wiring and are more expensive to operate than gas stoves. Another drawback is significant thermal inertia. However, in some advanced types of burners ( Hi-Light, induction — see below), this drawback is minimized. Also, note that all electric burners are demanding on the shape of the dishes: they must have a flat bottom for tight contact with the burner, and induction heaters are also limited in materials.
— Combined. A hob that combines gas and electric burners. The most popular format of such models is “3 + 1”, 3 gas burners and 1 electric. So we are talking about gas stoves, supplemented by an electric burner. The most notable advantage of such hobs is the ability to work even if one of the energy sources is not available. In addition, the combination of different burners allows the user to choose the optimal type of heating for a given situation. At the same time, such versatility is rarely necessary, and when connected, combined hobs combine all the complexities of gas and electric ones: they require gas supply, the participation of a specialist, and high-quality wiring. As a result, there are relatively few such models produced, and they are designed mainly for those who want to have an option in case of problems with gas supply.Door closer
Such a device is responsible for pulling the door when closing and, in some models when opening. The idea is that the user does not need to close/open the door completely — pull it to the right place, and then the door will be "picked up" by the
door closer and smoothly brought to a fully open or closed state. Such a system eliminates the risk of leaving the oven not completely closed and prolongs the life span of the device.
Hob material
— 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.Number of gas burners
The number of traditional gas burners in the stove design (excluding turbo burners, see below). The classic option for a household stove with an oven (regardless of the type of hob) is
4 burners — it provides good multi-tasking and, at the same time, allows you to keep the dimensions of the device within reasonable limits.
Number of Hi-Light burners
The number of Hi-Light burners in the stove design.
Hi-Light is an improved kind of electric burner in comparison with the solid plate ones described above (see "Hob type"). In such burners, the tubular heating element is replaced by a thin metal strip, and the working surface is usually made of glass-ceramic (see "Hob material"). Due to this, the heating and cooling rate of such burners is much higher than that of solid plate ones (although it does not reach the instantaneous reaction of gas stoves).
Dual-circuit burner
Dual-circuit burners are burners with the possibility of increasing the diameter.
Dual-circuit burners are only electric burners of the Hi-Light type or induction. Such a burner looks like several circles of different diameters with a common centre; each circle corresponds to one of the options for the working diameter that can be selected for the burner. The number of these options is usually 2 or 3. And if there is more than one dual-circuit burner, they may differ in the number of diameters available.
This feature allows you to optimally select the working size of the burner for the diameter of the dishes. This feature should not be confused with the oval dual zone (see below): the oval dual zone gives the burner an elongated shape, and the dual circuit burner remains round regardless of the selected size.
Residual heat indicator
The residual heat indicator is is used in electric stoves. It allows you to determine the presence of hot burners when the power is off, thus reducing the risk of burning yourself on a burner that has not had time to cool down. In addition, the presence of such an indicator helps to save energy.
Burner power
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.
Burner diameter
The heating power, the performance of the device and the speed of cooking depend on the diameter of the burners. The larger the burner, the more heat dissipation it has. Also, the diameter of the burner allows you to determine what sizes of dishes are suitable for use on the hob. Indeed, for induction models, this value is critical for high-quality heating. Burners can have the following diameter:
- small — about 145 mm, power within 1200 W;
- medium — about 180 mm, power within 1700 W;
- large — about 220 mm and more, power within 2000 W.
Some hobs use dual-circuit burners that allow you to adjust the diameter of the heating zone. If it is indicated that the diameter of the burner is 180, 200, 220 mm, then the heating zone on a particular burner can be narrowed and/or expanded, depending on the size of the dishes used.
