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.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.
Connected load
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.
