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.
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.Guides
Type of tray guides provided in the oven.
— Frame. The simplest guides are made in the form of a fixed grid, and sometimes in the form of slots in the walls of the oven. They are quite practical and inexpensive, due to which they are used in the vast majority of ovens. The main disadvantage of the lattice guides can be called the fact that the baking sheet moves rather tightly in them, especially if the oven has not been cleaned for some time and the guides are dirty.
—
Telescopic. Guides in the form of retractable tray support based on telescopic rails. When removing the baking sheet, the mechanism moves apart, and the stand, rolling on a special roller, “leaves” the oven. The main advantage of the "telescopic rails over the classic frame guides is that you do not need to make much effort to install and remove the baking sheet — it will move very easily. On the other hand, such devices are more expensive and more complicated than classic frame guides; as they get dirty, their efficiency drops noticeably, and dirt can completely disable the mechanism. In light of all this, manufacturers most often use telescopic rails not as the main option but as an addition to the frame guides described above. If telescopic guides are initially indicated in the specs of the stove, this usually means that the oven with traditional frame guides is additionally equipped with removable telescopic guides. These advanced telescopic rails ca
...n be easily set at the desired level and removed for cleaning.
Many ovens, initially equipped only with frame guides, can be equipped with telescopic rails, purchased separately.Number of glass in door
It is the number of layers of glass installed in the oven door. The larger it is, the less heat goes out, and the less the outer surface heats up. The minimum amount required for effective thermal insulation is 2 glasses, and this option is considered the most popular.
Ovens with 3 glasses are noticeably less common, mainly middle and high-end models. The maximum number of glasses is 4; such thermal insulation is the most effective. However, it is not cheap and is used extremely rarely, mainly in top-class stoves.
Oval dual zone
The presence of an
oval dual zone on the hob. Such a heater is useful for working with appropriate elongated dishes (for example, oval roasting pots). 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 additional segment is connected, it turns into an oval. In gas models, a burner with an oval flame is installed, or two small burners located close to each other.
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.
