The type of auto-ignition provided in the stove.
Auto-ignition systems are used only for gas burners and ovens. They work based on an electric spark, from which the gas ignites, and greatly simplifies the ignition of the stove, eliminating the need for matches, lighters and other sources of fire. Auto ignition can be provided
for a hob(hob),
for an oven, or both. In all these cases, it is assumed that the ignition is activated automatically when the knob is turned. There is also another option for electric ignition — a special button. Such systems are somewhat simpler and cheaper, while they usually cover all gas heaters available in the stove (therefore, the location is not indicated for push-button electric ignition).
Anyway, the stove requires mains for this function to work.
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.
