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.
Minimum temperature
The lowest temperature the oven can provide. Usually, it is in the range of +30 to +50 ˚C. So, for example, the minimum heating temperature at +30 ˚C allows you to defrost products. Models with a minimum of 40 ˚C and 50 ˚C allow you to heat ready meals, heat tableware (before serving), dry rusk, etc.
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.
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.
