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.
Oven cleaning
It is the method of cleaning the inner surface provided in the design of the oven. In addition to traditional and more advanced
steam cleaning, there are
catalytic and
pyrolytic cleaning. More about them:
— Traditional. This option assumes the absence of any devices that facilitate cleaning: you have to wash the oven manually, using ordinary detergents and cleaning products. Such a procedure can be quite troublesome and time-consuming, but such ovens are much cheaper than similar models with more advanced types of cleaning.
— Pyrolytic. Cleaning with high temperature. Dirt on the interior surfaces of the oven is burned to ash, which can then be easily removed without using detergents. At the same time, pyrolytic cleaning equally effectively handles all types of dirt, both new and old. The disadvantages of such a system are the duration of cleaning (sometimes up to several hours), high cost, and significant consumption of resources (electricity or gas, depending on the type of oven). In addition, during the operation of the cleaning system, unpleasant odours often arise, generated by the combustion of contaminants in the oven.
— Catalytic. Ovens with this type of cleaning have a special coating on the inner surface that breaks down grease on the oven walls. Fat disintegration is accelerated at high temperatures; the oven is thus self-cleaning t
...o a certain extent. However, the efficiency of catalytic cleaning is lower than that of pyrolytic cleaning. It is unable to cope with the entire amount of fat on the walls. Therefore, such an oven should be washed from time to time. On the other hand, ovens with catalytic cleaning are cheaper than ones with pyrolytic cleaning. And the cleaning itself does not require additional electricity/gas costs, nor is time-consuming (except for washing/wiping).
— Steam cleaning. Cleaning the oven with heated steam. A certain volume of water is poured into a baking sheet or another container, the container is placed in the oven and the cleaning mode is turned on. Due to heating, the water evaporates, and the heated steam softens the dirt on the walls and partially disintegrates the fat. After the end of the programme, it is enough to wipe the oven with a damp cloth. Such a cleaning requires less time and resources than pyrolysis and often turns out to be more effective than catalytic — steam can soften even old dried-up contaminants. At the same time, these ovens are relatively inexpensive. At the same time, this mode does not guarantee to cope with any contamination. It is possible that after the end of the steam cleaning, the oven will have to be washed traditionally.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.
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.
