Choose induction if your cookware is compatible and your electrical circuit can support the hob you have in mind. A ceramic hob lets you keep using pans that don’t work on induction, while a dual-fuel hob is a good option if you want to retain gas burners, provided you also check the connection and ventilation. Before replacing your hob, compare the existing cut-out with the installation requirements in the manual for your chosen model.
If you use a range of cookware, check the pans you use most often before switching to induction. Electrolux recommends testing the base with a magnet. You should also check the compatible diameters in the manual for the hob you’re considering.
To keep your worktop as it is, measure the cut-out and the space beneath the hob, then compare them with the installation diagram for your chosen model. The number of cooking zones and electrical requirements matter just as much as the stated width.
A dual-fuel hob lets you have gas burners and an induction zone in the same appliance. Check the available space, electrical connection and gas supply. GRDF reminds users that gas cooking appliances need suitable ventilation.
Worth considering if: your main pans are suitable for induction and your electrical installation can support the hob.
The trade-off: you may need to replace some cookware if its base isn’t compatible.
Worth considering if: keeping non-magnetic pans is a priority when replacing your hob.
Bear in mind: the ADEME’s reference energy consumption is higher for an average ceramic hob than for the induction hob included in its comparison. These figures are not measurements for every model.
Worth considering if: you want to keep cooking with gas while also using induction with compatible pans.
The trade-off: your plans need to meet the requirements for space, electricity, gas connection and ventilation.
Once you’ve chosen a technology, compare each model with your cookware, existing cut-out and the way you use your cooking zones.
| Priority | What to check | What I need |
|---|---|---|
| Cookware | For each induction zone, test the base of your pans with a magnet. Also check the compatible diameters in the model’s manual. | I want to keep using my usual saucepans and frying pans, without finding out after installation that an induction zone doesn’t recognise them. |
| Electricity consumption | In the ADEME table, based on 409 cycles a year, the figure is 200 kWh/year for an average ceramic hob and 115 kWh/year for the induction hob used in this comparison. These figures are not measurements for the models featured here. | I’m interested in reducing the electricity I use for cooking, but I’ll compare hobs without treating these reference figures as a prediction of my future consumption. |
| Installation and connection | Compare the cut-out, space beneath the worktop and connection diagram for the exact model. For induction, Enedis specifies, among other things, a dedicated circuit and a 30 mA Type A residual current device. With gas, also check ventilation requirements for your home’s layout. | I’m replacing a built-in hob and want to know whether the new one will fit in my kitchen before I order it. |
| Cooking zone layout | Count the zones you’ll actually have and check their dimensions. On a dual-fuel hob, identify which zones are gas and which are induction. Only factor in a flexible zone if the model you’re considering has one. | I need a layout that suits the way I cook, whether I’m using several pans or a large dish. |
If a magnet won’t stick to the base of a pan, you may not be able to use it on an induction zone. The compatible diameter also depends on the hob.
Test the saucepans and frying pans you use every day, then check the manual for the requirements of each zone.
You’ll need to replace any incompatible pans if you want to keep using them for those dishes.
Bosch product specifications show models with similar external widths but different heights and numbers of cooking zones. The stated width is no substitute for the installation diagram.
Measure the existing opening and the space beneath the worktop, then check the clearance required for the exact model.
An unsuitable cut-out or insufficient clearance may mean modifying the worktop or arranging installation work.
The ADEME comparison is based on its reference conditions. It doesn’t describe the energy consumption of a specific model in your kitchen.
Use it to compare technologies, then look at the model you’re considering and your cooking habits. Don’t treat it as a guaranteed result.
Induction zones still need compatible cookware, while gas burners require a suitable connection and ventilation.
Before choosing a dual-fuel hob, have the gas and ventilation arrangements checked, along with the space and electrical connection required.
Bosch offers built-in induction and ceramic hobs. Its product specifications let you compare specific models rather than relying on the stated width alone.
Electrolux offers induction hobs, as well as models that combine induction and gas.
Whirlpool’s range in France includes hobs with different technologies, including induction and gas.
This selection includes one ceramic hob and four induction hobs, one of which has an integrated extractor. First choose the technology that suits the way you cook, then check the installation requirements for each model.

A four-zone option if you want to keep using pans that aren’t compatible with induction. Before replacing a built-in hob, compare the cut-out and electrical connection with the AKT 801-NE’s installation instructions.

Its four zones are suited to cooking several dishes at once, provided you use induction-compatible cookware. Check the installation dimensions, electrical circuit and cable configuration before installation.

This four-zone model has nine power levels and could suit an induction replacement if your cookware is compatible. Compare its cut-out and electrical requirements with your installation before choosing.

This model combines four induction cooking zones with an integrated extractor, making it an option if your replacement plans include extraction. Check the installation and ventilation space, electrical compatibility and the CBEHKIT installation accessories, which need to be purchased separately.

Its three zones are worth considering if they meet your everyday cooking needs. Use induction-compatible cookware and have the cut-out, clearances and dedicated circuit required for this model checked.
Test the base with a magnet: Electrolux says it should stick. Then check the hob’s manual to see which pan diameters are suitable for the zones you’ll use.
Not necessarily. Enedis says that an induction hob needs, among other things, a dedicated circuit and a 30 mA Type A residual current device. Have the connection checked, then compare the cut-out and clearances with the new model’s manual.
No. You need to be able to install the necessary connections and provide suitable ventilation for gas cooking appliances, as GRDF reminds users. Check the width and cut-out of the dual-fuel hob you’re considering before buying.
That can’t be guaranteed for every model and every use. Based on 409 cycles a year, the ADEME table gives figures of 200 kWh/year for an average ceramic hob and 115 kWh/year for the induction hob in its comparison. Your consumption will depend on the hob and how you use it.
The stated width alone isn’t enough to tell. Specifications for several Bosch hobs list their external dimensions, but you’ll need to compare the installation diagram for your chosen model with the measured opening and the space available beneath the worktop.
