Comparison Bosch HBG 73B530 vs Bosch HBG 33B520

The working capacity of the oven. The amount of food that can be cooked in the device and the amount of space required for embedding depends on this parameter.

A capacity of about 50 – 60 litres is considered quite sufficient for a family of 2 – 3 people. It is the capacity that most modern built-in ovens have. However, there are other options — modest models of 20 – 30 litres, similar in capacity to microwave ovens, large in capacity for home baking and large cabinets of 100 litres or more, designed more for cafes and restaurants than for home use.

The number of cooking modes provided in the design of the oven. In this case, the cooking mode means the general opertaion mode — for example, “heating”, “heating + convection”, etc. Accordingly, this indicator strongly depends on additional equipment (see "Features"). However, even in similar models, the number of modes may be different. In general, the more cooking modes, the more cooking options, the easier it will be to choose the optimal mode for a specific situation.

The type of inner cleaning provided in the oven. Note that pollution has to be removed with a rag or sponge, but modern ovens often provide various tricks that facilitate the process. The options might be:

— Catalytic. A special wall coating is used in ovens with this cleaning method: it breaks down fats and other stubborn dirt into constituent elements that can be easily removed. The effectiveness of such a coating decreases over time, but it is enough for at least several years of full use. It should be noted that the catalytic coating can be implemented by applying it to special removable plates that are installed on the back or side walls of the oven chamber.

— Steam cleaning. Cleaning with hot steam, which softens dried-on dirt and partially breaks down fats. In some models, there is a built-in steam generator for this, in others it is enough to put a container of water in the working chamber and turn on the cleaning program.

— Pyrolytic. Cleaning by heating the chamber to a very high temperature — about 500 ° C. At this temperature, most of the contaminants are incinerated into ash, which can then be easily removed. Pyrolytic cleaning is considered the most effective, but ovens with this function are expensive, time consuming, require significant electricity/gas consumption, and can lead to unpleasant odors.

This indicator characterizes how economically the oven consumes electricity. Initially, classes were marked in Latin letters from A(highest) and further down as they went down. Later improved classes A +, A ++, etc. appeared (the more pluses, the better). More energy-efficient models are more expensive but can pay for themselves in the process of use, especially if you have to cook often and in large quantities.

The electrical power consumed by the oven during operation, in other words, the power that must be supplied to the oven so that it can work normally. This parameter determines not only the total energy consumption (and, accordingly, the amount of electricity bills) but also the specifics of the power supply: with a power consumption of several kilowatts, a conventional outlet may not be suitable, and the wiring must be quite reliable.

Note that it is customary to indicate the connection power only for electric models (see "Oven"), as well as for gas devices with electric grills.
