Sales of cooktop have steadily increased over the past 15 years, to the detriment of cooks.

The cooktop last for the cooking plates, the induction table. The wind in its stern and now represents more than one cooktop out of two. Why do induction tables appeal? Our buying guide decrypts the market to help you make the best choice.


4, 3 or 2 zones

Historically equipped with 4 zones, like their gas congeners. The induction tables have been able to play the innovation card. This 3 e area is usually very wide (greater than 28 cm). It allows the use of large containers such as bowls jam, pans of large diameter. But the 3 cheaper zones are most often equipped with 3 conventional fireplaces. That is equivalent to a 4 zone table to which a zone has been removed.

Coock-topThe most generous induction plates can have up to 5 cooking zones. That does not require a few installation and electrical connections. There remain the “dominoes”, these very narrow cooktops that consist only of 2 cooking zones, or even a single one. They are particularly appreciated in urban areas. Also, can replace the traditional domino of 2 electric plates in cast iron that equips the kitchenettes.

Mixed induction cooktops

As with the 3 + 1 mixed tables, there are mixed induction cooktops. The most often combine 2 induction zones with 2 gas fireplaces. More rarely, with 2 radiant fireplaces.

Advantage: by combining two technologies, one disregards to choose the most adapted to its container or its recipe.

Note that induction-gas mixed tables will always operate in the absence of electricity. with that the exception of the electric igniter. A good choice for those who live in areas where power cuts are common.

Expandable induction zones or modular zones

The tables with the expandable or modular area are the novelty of the last decade. With dimensions of approximately 40 × 20 cm.

  • Cook separately two dishes, with two distinct powers. Each disposing on one-half of the zone.
  • Cook a single large dish, placing the utensil over the entire area.

In 2011, models appeared with a single zone 100% modular. The power and cooking time are adjustable via a touch screen. This technology should become more widespread and democratic in the years to come.

Diameters of fireplaces and power

The operation of induction tables can be disruptive to many new users. And may become a source of questions and/or dissatisfaction. In general, the induction zones “adapt” to the diameter. The bottom of the container used, up to a certain limit. Containers of too small a diameter will not necessarily work on induction.

Similarly, if you want to exploit the full power of an induction heater. It is imperative to use a container whose bottom is of diameter equal to the focus in question. The efficiency of the induction zone is related to the diameter of the container. If it is smaller than the recommended minimum diameter. It will receive only a part of the maximum power of the area in question.

We recommend using a container whose diameter is as close as possible to the diameter of the induction zone.


We are referring to the diameter of the bottom and not to the diameter of the container. This difference is particularly important for frying pans. A 26 cm diameter pan has a much smaller diameter base.
