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.
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.
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.
