Anyone planning to buy a new hob will soon find themselves wondering about the difference between Ceran® and induction. Both technologies use glass-ceramics, but they work in different ways from a technical point of view. Find out how different hobs compare, what advantages they offer, and which heating method suits modern cooking habits.
Many people wonder what the difference is between Ceran® and induction hobs, and how this affects everyday life in the kitchen. Ceran® is widely used in everyday language, but strictly speaking it refers only to the manufacturer of the glass-ceramic surface. The key factor is the type of heating element used beneath the glass-ceramic hob.
Ceran® is a glass-ceramic product manufactured by Schott. It is particularly heat-resistant and forms the sturdy surface that defines the look of the hob. However, the glass-ceramic itself does not generate any heat. The key factor is how the hob underneath is heated. What is commonly referred to as a Ceran® hob is usually a radiant-heated electric hob, in which a heating coil beneath the glass-ceramic surface transfers heat to the surface. This, in turn, transfers the heat to the cookware.
This technique works with almost all pots and pans and offers great flexibility. However, the interface is sluggish: Heat builds up gradually and residual heat remains after the appliance is switched off. Its energy efficiency is relatively low, as heat is lost through the glass-ceramic hob and into the surrounding area.
In an induction hob, an induction coil operates beneath the glass-ceramic surface. As soon as the hob is switched on, the coil generates a magnetic field which immediately generates heat in the base of the cookware. The glass-ceramic surface is therefore only heated indirectly. The result is rapid and very precise heat build-up.
To use an induction hob, you need cookware with a magnetic base. Stainless steel with a magnetic base, enamelled steel or cast iron are particularly suitable. Direct energy transfer ensures that heat is available immediately and can be precisely controlled. It also improves safety, as the surface stays cooler and the hob switches off automatically if no pan is placed on it.
In everyday life, the question often arises as to which technology is best suited to one’s own cooking needs. The following table highlights the key differences.
| Criterion | Ceran® (radiant heating) | Induction hob |
|---|---|---|
| How it works | Heating coil generates radiant heat | A magnetic field heats the base of the pan directly |
| Speed | slower | very fast |
| Heating area | Entire heating coil, regardless of the size of the cookware | Limited to the size of the cookware |
| Energy efficiency | rather low, high heat loss | high, minimal energy loss |
| Safety | higher surface temperature | lower surface temperature |
| Cookware | almost any type can be used | magnetisable cookware required |
As well as the technology, convenience features and practical aspects are also relevant.
| Type | Ceran® (radiant heating) | Induction |
|---|---|---|
| Cleaning | The surface gets hotter, so dirt burns on more quickly | Less heat makes cleaning easier afterwards |
| Cooking convenience | even heat, but slow response | very precise, fast response |
| Noise level | silent | may produce a faint hum |
| Heat radiation | high | low |
| Purchase cost | Standard option; also available in budget versions | More complex technology, therefore slightly more expensive to buy; possible additional purchase costs for new cookware |

To install a high-performance induction or radiant hob, a three-phase high-voltage connection (3N, 400V) is usually required in order to utilise the technology to its full potential. Whilst the existing wiring is often sufficient for a simple switch from Ceran® to induction hobs, modernising an older kitchen may require modifications to the electrical installation or a higher fuse rating. Always have the installation checked and supervised by a professional to ensure maximum safety when cooking.
For both options, it is also important to ensure the correct installation dimensions and adequate ventilation in the base unit.
Anyone who frequently uses large pans, values traditional heat build-up or already has a lot of cookware will find a radiant hob a good choice. These hobs are reliable and cater for a wide range of cooking methods.
For amateur cooks who value maximum convenience, precise heat control and energy efficiency, an induction hob is the better choice. Direct heat transfer saves time and energy, which is particularly noticeable in everyday cooking. Cleaning is also easier, as the surface does not get as hot.
When choosing the right hob, you should take your cooking habits and the level of ease of use you require into account. Induction is now regarded as a particularly modern solution that combines efficiency and precision.
How do induction hobs and Ceran® hobs differ in terms of durability and lifespan?
Both induction and Ceran® hobs feature a robust glass-ceramic surface which, if properly looked after, can last for 10 to 15 years.
Induction hobs are generally safe for most people to use. Anyone with a pacemaker or implanted medical device should follow the manufacturer's instructions for the implant and the hob and seek medical advice if in doubt – especially if there is uncertainty or warnings are mentioned in the manual.
Not necessarily. The decisive factor is whether the base of the pot or pan can be magnetised. Older pots and pans made of cast iron or enamel are also suitable. There are often symbols stamped on the outside of the pot base that indicate which types of heat the pot is suitable for.
A simple test: if a magnet sticks to the base, the cookware is usually suitable for induction hobs. Many households can continue to use their existing pots and pans and only need to add a few new items.
A slight humming or buzzing noise may occur, depending on the power setting and cookware (base structure, material mix). High-quality, flat bases often reduce noise significantly. Radiant hobs, on the other hand, are usually silent.
The most reliable way to identify your hob type is to check the model number in the manual or on the type plate (usually on the underside).
A quick practical check: if the hob becomes noticeably warm or even red without a pan on it, it is usually radiant heating. With induction, nothing happens without suitable cookware.
