What is induction cooking?
An induction hob uses electricity and a magnetic field to heat a compatible pan directly. A conventional ceramic hob heats its cooking zone first, while a gas hob heats cookware with a flame. Induction can respond quickly when you change the power setting, but the result depends on the pan, the hob and the food being cooked. Bosch's explanation of induction cooking describes the coils and magnetic cookware that make this possible.
The pan becomes hot and can transfer heat back to the glass. Do not treat an induction surface as safe to touch during or immediately after cooking. Check the residual-heat indicator and follow the instructions for your particular hob.
How does an induction hob work?
Coils beneath the glass create a changing magnetic field. With a suitable pan in place, energy is transferred to its base, which heats the food. The hob detects suitable cookware on a cooking zone; features and zone sizes vary by model. Heating the pan directly can reduce some heat lost around the cooking zone, but it does not mean that no heat or electricity is wasted.
Induction and ceramic hobs can look similar, so check the product description before buying. A ceramic hob uses a heating element beneath the glass and generally accepts a wider range of cookware. Gas offers a visible flame but needs the correct connection and ventilation. Compare the actual models and installation requirements rather than assuming every hob of one type behaves the same way.
Which pans work?
The base of the pan must be suitable for induction. A magnet that attaches firmly to the base is a useful first check, but you should also look for the maker's induction symbol and check that the base fits the cooking zone. Cast iron, enamelled steel and some stainless-steel pans can work. Ordinary aluminium, copper and glass pans generally do not work unless they have a suitable magnetic base. Bosch's cookware guidance explains the material and size requirements.
Test the pans you own before budgeting for a new hob. You may need to replace only a few, rather than a complete set. Do not heat an empty pan: it can become very hot quickly and may damage the pan or hob. Follow the cookware and hob makers' safety instructions.
Speed, energy and running costs
Directly heating a suitable pan can make induction quick to respond and convenient for boiling or simmering. That does not guarantee that every meal takes less time or costs less than using gas or another electric hob. Pan size, cooking method, power setting, energy tariff and the efficiency of the particular hob all affect the outcome. Faster heating alone does not prove lower household bills or a specific environmental saving.
When comparing products, check the rated power, useful features, dimensions and total installed cost. For wider kitchen energy decisions, read our practical energy-use guide. Use the real specifications of the models you are considering rather than a blanket saving claim.
Safety and installation
Induction removes an open flame and many models include pan detection, child locks and residual-heat indicators. These features can help, but they do not remove the risk from hot cookware, hot food or a zone warmed by a pan. Bosch's residual-heat advice explicitly warns that the cooking zone can remain hot after use. Keep children away from hot pans and wait for the zone to cool before cleaning it.
Check the electrical requirements and cut-out dimensions of the exact hob, and arrange suitable installation where needed. If you use a pacemaker or another implanted medical device, follow the device maker's advice and the hob maker's instructions rather than relying on a general reassurance about electromagnetic fields.
Is it right for your kitchen?
Induction may suit you if you want responsive electric cooking and already own suitable pans, or are willing to replace those that are not compatible. Before choosing, compare the available space, zone layout, controls, pan detection, installation quote and total cost with a ceramic or gas alternative. A small magnet test and a careful look at the product manual can prevent an expensive mismatch.
