Buying an induction hob: what matters when choosing, installing and using one

An induction hob can be a practical solution for fast-paced everyday cooking – from a portable single hob in student accommodation to a built-in hob with four zones. The choice ranges from an induction hot plate and double induction hot plate to a standalone built-in appliance. However, differences in power, connection and pan compatibility often only become apparent after purchase.

Common pitfalls when buying an induction hob

1. Wattage alone does not tell you much

A high total power rating sounds convincing at first. However, on an induction hob with several plates, the available power is distributed between the cooking zones depending on the model. A 4-zone hob with 7,200 watts offers different capacity from a 2-zone model with 3,000 or 3,500 watts. The key question is whether you want to boil water, heat a frying pan and keep a sauce warm at the same time.

With a portable induction hob rated at 2,000 watts, the power is generally available to just one zone. This is often enough for a saucepan or frying pan; for preparing several dishes at once, an induction hob with 4 plates is more suitable.

2. Induction is confused with a ceramic hob

A ceramic hob, or conventional electric hot plate, heats the glass surface first and then the cookware. With induction, the magnetic field is generated directly in the suitable base of the pan. This does not mean the surface stays cold: heat from the hot pan can make it noticeably warm during use.

A common cause of a wrong purchase is that existing pans are not magnetic. Hold a magnet against the underside. If it does not stick firmly enough, the cookware is not suitable for many induction appliances. You should also check the information on pan size and the permitted base shape in the relevant product description and instruction manual.

3. Built-in dimensions and connections are overlooked

A built-in induction hob must fit the worktop precisely. The key measurements are not just the external dimensions, but above all the cut-out dimensions, installation height and space required for ventilation. For a 60-cm hob, typical cut-outs are approximately 56 × 49 cm, for example – but the specifications for the particular model are always definitive.

The electrical connection also varies. Portable hot plates are usually operated via a plug. Some built-in appliances, on the other hand, do not have a plug and require a proper connection to the mains. For high connection loads, installation should be carried out by a qualified electrician.

Important buying criteria explained clearly

Cooking zones and power

  • One zone: Suitable for offices, camping, small flats or as an additional cooking point.
  • Two zones: A good compromise for smaller households and preparing two dishes at the same time.
  • Three to four zones: Ideal for families, frequent cooking and using several pans at once.
  • Power boost function: Temporarily increases the power of one zone. Check whether this limits the power available to other zones.
  • Power levels: Nine to 17 levels allow more precise adjustment than simple temperature controls.

Controls and timer

A touch-control hob is easy to wipe clean, but it does not always respond reliably to wet or greasy fingers. Clearly visible displays and separate controls for each cooking zone are useful features.

An induction hob with a timer can switch off a zone automatically after the set time. Check whether the timer is available separately for each zone and what range it covers, such as 1 to 99 minutes or up to 180 minutes on certain portable appliances.

Safety features

Look for clearly explained functions such as:

  • Pan detection, which prevents or stops operation without suitable cookware
  • Overheating protection and automatic switch-off
  • Residual heat indicator, as the glass surface may remain hot after cooking
  • Child lock, which prevents accidental inputs
  • Overflow protection or shut-off when cookware is empty, where available

These features reduce certain operating risks, but they do not replace supervision while cooking. Metal objects should not be left on the active surface. Anyone with a pacemaker should read the appliance manufacturer's guidance and, where necessary, seek medical advice before use.

Portable hot plate or built-in hob?

A portable induction hot plate is a sensible choice if you want to remain flexible or are not planning any structural changes. It can be stored in a cupboard and used when needed on a stable, heat-resistant surface. Make sure there is sufficient ventilation and clear space around the ventilation openings.

A built-in 2-plate induction hob is a good fit for small kitchens and one-person households. A 3- or 4-zone model provides more space, but requires a suitable worktop cut-out and often a fixed electrical connection.

If you do not own induction-compatible pans, you can alternatively choose a conventional electric hot plate or ceramic hob. These appliances are generally less selective when it comes to cookware, but use a different heating technology and respond differently to changes in temperature.

Induction hob FAQ

Which pans work on an induction hob?

Pans and frying pans with a magnetic base are suitable, including those made from cast iron or magnetic stainless steel. A magnet test on the underside provides an initial indication. The instructions for the particular hob and cookware remain decisive.

How much does it cost to run an induction hob?

The cost depends on the power rating, usage time, electricity tariff and cooking method. For a rough estimate, multiply the power in kilowatts by the operating time in hours and your electricity price. A 2,000-watt hot plate running at full power for one hour uses 2 kilowatt-hours in theory. In everyday use, the highest setting is rarely used continuously.

How long does an induction hob last?

Its lifespan depends, among other things, on how intensively it is used, ventilation, cleaning and correct operation. Avoid using empty pans, blocking the ventilation openings, harsh cleaning products and heavy impacts on the glass surface. For a built-in appliance, repairs and electrical work should only be carried out in accordance with the manufacturer's instructions and by suitably qualified professionals.
