Cooking temperature
The cooking temperature range allows you to understand which special tasks are subject to the oven. The lower temperature from which the oven starts heating, usually, 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 crackers, etc.
Number of door glasses
The number of layers of glass in the viewing window of the oven door.
Modern models, usually, have from 2 to 4 glasses. The
more glasses, the less heat loss and the more economical the oven, but this parameter also affects the cost.
Guides
Type of guides for installing baking sheets that are used in the oven.
—
Frame. Classic guides have the form of slots with protrusions in the side walls of the oven. This design is simple and inexpensive. However, it is not very convenient — when removing baking sheets, you have to pull your hand into a heated oven, which means you will need a mitten or potholder. And the extraction itself may require effort, especially if the guides are dirty and the trays go tight in them.
—
Telescopic. Retractable guides on which the baking sheet “leaves” the oven, usually, immediately when the door is opened. Such devices are more convenient than frame ones, but they are more expensive and not suitable for all situations (for example, sometimes to check a dish you only need to open the lid without pulling it out). Therefore, in most models,
telescopic guides are only on one level. But
telescopic guides on two levels or even
three levels already classifies the device as a top segment.
Dimensions (HxWxD)
In the case of ovens, the dimensions determine not only the sizes, but also the conditional form factor and the possibility of installing models. Dividing by height, the devices can be
compact(low) for installation in hanging cabinets and
full-sized — classic ovens for installation under the countertop. As for the width, in addition to
standard models of 60 cm, there are
narrow (45 cm) and
wide (90 cm) models to interact with similar wide hobs.
