Dual-circuit burner

The presence on the hob of one or more dual-circuit burners — heaters with the possibility of increasing the diameter.

Only Hi-Light or induction hotplates can be dual-circuit burners (see "burner type"). Such a heater looks like several circles of different diameters with a common centre; each circle corresponds to one of the options of 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.

Anyway, this feature allows you to select the working size of the burner for the diameter of the dishes. This function 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.

Oval dual zone

The presence of an oval-shaped heating zone on the hob. Such a heater is useful for working with appropriate elongated dishes (for example, goose roasters). In models with electric heaters (see "Burner type") the desired shape is provided by an additional segment installed close to the burner; the burner in normal mode works like a regular round one, and when the segment is connected, it turns into an oval. In gas models, a separate elongated burner is installed.

A similar effect can be achieved using the bridge mode (see "Features"). However, the bridge and the oval zone are still different functions: the first involves combining two burners, and the second is implemented strictly on one burner.

Input power

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.

Frame

The presence of a metal frame in the design of the hob. Such a frame can be located both around the entire perimeter of the device (in most classic models) and only on one side (usually in domino hobs, see "Design" for more details). The frame plays an aesthetic role, allowing you to optimally fit the hob into the overall design of the kitchen. However, it can also perform a very practical function: to retain liquids spilt onto the surface. On the other hand, such protection also has disadvantages: it can be quite difficult to clean dirt near the frame, and the liquid retained on the hob can burn, making cleaning even more difficult. So in terms of cleaning, models without a frame are more convenient.

Dimensions (WxD)

General dimensions of the device in width and depth. Depth, in this case, refers to the distance from the leading edge to the trailing edge (when viewed from the user's side). Note that the external dimensions of the hobs are often larger than the dimensions for embedding (see below).

Cut-out dimensions (WxD)

The size of the opening that needs to be made in the kitchen countertop for the normal embedding of the hob. By default, the width and depth are indicated — the size of the opening along the front and side sides, respectively (when viewed from the user's side). Note that the dimensions of the hob itself are usually larger than the dimensions for embedding: when installed in an opening, the upper part of the surface rests on its edges, so that the device does not fall into the countertop.
