If you’re thinking of switching to induction, first test the base of each pan with a magnet, then check the compatible diameters for the hob you’re considering. If you use lots of non-compatible cookware and want to keep it, compare ceramic hobs instead. A mixed induction and gas hob is only an option if your kitchen already has a suitable gas supply. Whatever the technology, check the model’s instructions against your kitchen’s worktop cut-out, clearance requirements and electrical supply.
Test the base of your pans with a magnet. Then compare their diameters with those accepted by the zones on your new hob. Electrolux France explains that compatible diameters vary by model.
If some of your cookware doesn’t have a ferromagnetic base, it’s worth comparing a ceramic hob with an induction one. Also check that the bases are suitable for your chosen hob, and follow its instructions for use.
The visible width alone won’t confirm that it will fit. Measure the worktop cut-out and the space beneath the hob, then have the electrical connection checked against the instructions for the model.
Consider it: if the cookware you want to keep has a base that attracts a magnet and is the right diameter for the zones.
The trade-off: cookware without a suitable ferromagnetic base will need to be used for something else or replaced.
Consider it: if keeping cookware without a ferromagnetic base matters more to you than switching to induction.
The trade-off: according to a comparison published by Bosch Home Appliances France, induction heats more quickly and directly.
Consider it: if you already have a suitable gas supply and want to use both induction-compatible cookware and other types of cookware.
The trade-off: you’ll need to check the requirements for the induction zones, as well as the gas installation and connection. Creating or modifying a gas supply requires a separate assessment.
Make a list of the cookware you want to keep, then check the installation requirements for your chosen technology.
| Priority | What to check | Your needs |
|---|---|---|
| Cookware compatibility | For induction, test whether a magnet sticks to the underside of each pan. Also check that the base is flat and that its diameter is accepted, as stated in the hob’s instructions. | I want to know which pans I can keep using before choosing an induction hob. |
| Cooking method | Understand the difference between induction, which requires a suitable ferromagnetic base, and radiant or halogen ceramic zones. In its comparison of the two technologies, Bosch Home Appliances France describes induction as quicker and more direct. | I’m interested in faster heating, but I need to decide whether it’s worth replacing some of my cookware. |
| Fitting and power supply | Compare the actual cut-out and required clearances with the diagram for the exact model. Have its connection rating and compatibility with your existing electrical circuit checked. | My new hob needs to fit and connect properly in my kitchen, not just have the same visible width as the old one. |
| Cookware not compatible with induction | Compare a ceramic hob and, only if your kitchen already supports it, a mixed induction and gas hob. For a mixed hob, check the requirements for the induction zones and gas separately. | I want to keep using some cookware without a ferromagnetic base, without assuming it will work on an induction zone. |
Stainless steel cookware doesn’t necessarily have a base that’s suitable for induction. A base that attracts a magnet is the first thing to check; the zone must also accept its diameter.
Test the cookware you want to keep, and measure the bases of your smallest pans in particular before choosing your cooking zones.
If you choose a fully induction hob, you may need to replace any cookware that isn’t compatible.
Two hobs with a similar visible width may need different cut-outs, clearances or connections. For example, the installation dimensions listed by Whirlpool France are specific to each model.
Measure the opening and the space beneath the worktop, then compare them with the installation diagram and electrical specifications for the model you’re considering.
An unsuitable cut-out or power supply may mean modifying the cabinetry or arranging electrical work.
A mixed hob combines zones with different requirements: cookware must be suitable for the induction zones, while the burners need a suitable gas installation.
Only consider this option if you already have a suitable gas supply. Any plans to create or modify a gas connection should be assessed separately.
The cut-out and clearance requirements must match the exact model you’re buying, even if another hob looks a similar size.
Check the instructions and installation diagram for the exact model before confirming your choice.
The ranges below give you models to look at, but specifications shouldn’t be assumed to apply across different models.
Electrolux France offers a range that includes induction, ceramic and mixed hobs.
Bosch Home Appliances France provides information to help you compare induction with ceramic hobs and plan an installation.
Whirlpool France lists induction, ceramic and gas hobs.
These models represent two ways to replace your hob: choose ceramic to avoid induction’s requirement for a ferromagnetic base, or choose induction if your cookware and installation are suitable. For each model, check the instructions against your kitchen before ordering.

An option to consider if you want to keep cookware without a ferromagnetic base suitable for induction. Check the instructions for this model against your kitchen’s cut-out, clearances and electrical circuit.

Worth considering if you’re planning to switch to induction with your current cookware. Test the bases with a magnet, check the diameters accepted in the instructions and compare the installation requirements with your kitchen.

Another ceramic option if you want to avoid the requirement for a ferromagnetic base. The product name lists touch controls, a child lock and a residual heat indicator. Check the power rating in the instructions before having the electrical circuit assessed.

This induction model has a Bridge function, as stated in its name. Before choosing it, check the bases and diameters of your cookware, then compare the cut-out diagram and ventilation requirements with your intended location.

Worth comparing if your cookware meets the requirements for induction. The product name lists a Boost function, a timer and a residual heat indicator. Check the instructions for accepted diameters, installation and connection requirements.
Place a magnet against the base of each pan. According to Electrolux France, it should stick as a first indication. Then check the condition of the base and the diameters accepted by the zones on the hob you’re considering. The material name alone isn’t enough to tell you.
It doesn’t require the ferromagnetic base needed for induction, so it’s worth considering if you want to keep this cookware. However, check that it’s suitable for the use described in the instructions. Bosch Home Appliances France describes induction as quicker and more direct than ceramic.
Don’t assume it will. Measure the actual opening in the worktop and the space beneath the hob, then compare them with the installation diagram for the exact model. Check the specified clearances and ventilation requirements before ordering too.
Ask a suitably qualified professional to compare the hob’s power rating and connection diagram with your existing circuit. In France, Promotelec cites NF C 15-100 as the standard for new, fully renovated, modified or extended installations. You can’t determine whether your installation is compliant and suitable from the new hob’s product details alone.
It may have an induction zone for suitable cookware and gas burners for other types, but the layout varies by model. For example, Electrolux France says its KDI641723K combines one induction zone with three gas burners. Check the instructions and your existing gas installation. Any plans to create or modify a gas supply must be assessed separately.
