Oven capacity
It is the volume of the oven provided in the stove. It s the maximum volume of products that can be placed in it without compromising work efficiency. Accordingly, a
larger oven is useful for large volumes of cooking; on the other hand, such a capacity will significantly affect the price and dimensions of the stove.
If you buy a regular household stove with 4 burners and do not plan to cook a lot in the oven, you can not pay much attention to this parameter. The capacity of the oven is usually enough for most simple tasks like cooking a pie or baking chicken. But for more serious tasks, a larger oven may be required. Detailed recommendations on volumes can be found in special sources.
If there is an additional chamber (see below), this paragraph usually indicates only the volume of the main oven.
Max. temperature
The highest temperature that the oven can reach during normal operation. The minimum value in modern models is 230 °C. However, even this low temperature is considered sufficient for most simple dishes. The average indicator can be called 240 – 250 °C. Such heating is provided by most modern ovens. And the most advanced models can heat up to 300 °C or more. Such capabilities will be useful for some specific recipes that require high temperatures.
Power
Rated power of the oven installed in the stove. Specified only for electric ovens (see above). When determining this parameter, the power of all heaters and other devices installed in the oven (grill, convector, motorized spit, etc.) is taken into account; in other words, this item indicates the maximum power consumption.
This data is useful primarily for assessing electricity consumption, as well as the connected load during operation. But only ovens with similar functionality can be compared with each other in terms of power — for example, two models with convection. Otherwise, the comparison may be incorrect.
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.
Energy class
The energy class describes the overall efficiency of the cooker in terms of energy consumption. Note that we are not talking about actual consumption (see "Connected load" for details), but about the efficiency of the stove, about the efficiency of using the energy that it consumes.
This indicator is especially important for models with at least one electric burner or electric oven/grill. But, if we are talking about a purely gas stove, you can not pay much attention to the energy consumption class. Electricity in such models is spent only on additional functions like auto-ignition or oven lighting,
Initially, the classes were marked in Latin letters from
A(the most economical) and then alphabetically in order of decreasing efficiency — B, C, D ... Later, improved classes
A+,
A++ appeared; the more pluses, the higher the efficiency. Today, energy consumption in class A can be called medium, and in a lower class — high. The maximum indicator found in modern stoves is A++; if we are talking about a model with an electric burner, such a stove is usually expensive, but it pays off by saving electricity during use.
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.
