Induction hobs claim to offer the best of both worlds compared with gas and electric, combining the responsive heating of gas hobs with the easy cleaning of electric hobs.
They’ve taken domestic and professional kitchens by storm in recent years and induction hobs are an increasing favourite with chefs and home cooks alike.
We’ve highlighted five characteristics of induction hobs that you should know about before you make your choice.
Find out how 14 newly tested hobs, from the likes of AEG, Bosch and Neff, performed in our reviews of the best hobs – and discover which six induction hobs made it as Which? Best Buys.
1) Induction hobs heat up quickly
The best induction hobs are great for simmering stews slowly, they have responsive touchscreen control and are a breeze to clean. But speed is the main area where induction hobs have cut through the competition from gas and traditional electric ceramic hobs.
The chart below shows how quickly the fastest hob we’ve tested from each category boils a pan of water.
The best induction hob we’ve tested takes just three and a half minutes to boil a big pan of water – as fast as some kettles – compared with the best gas model’s toe-tapping eight minutes. Induction wins hands down.
If you’re a time-pressured or impatient cook, head to the fastest hobs we’ve found.
2) You need induction-compatible pans
You don’t necessarily need special ‘induction’ pans – but you will need pans that are made of, or contain, iron.
When you power up an induction hob, metal coils under the hob’s glass surface create a magnetic field. This interacts with the iron in a pan’s base. An electric current is generated that transfers energy into the pan, creating heat.
Some or all of the pans you already own might work, but it’s best to check. If a fridge magnet sticks firmly to the base, that’s a good sign.
If not, it’s easy to find induction-ready pans these days, though you’ll need to build the cost of new pans into your budget.
3) Induction can mean bigger cooking zones
Gone are the days of four standard-sized cooking zones on every hob.
Induction hobs have paved the way to joined-up cooking zones. These can create extended cooking areas variously called flexi, link or bridge zones. They let you cook using larger pots or dishes, which would extend beyond a standard heating zone.
To give you an idea, here’s a a couple of flexi-zone hobs from our latest hob reviews.
4) Induction hobs can affect pacemakers
Most common household electrical appliances are not a problem for pacemaker users, but the British Heart Foundation advises that you should keep a distance of at least 60cm from an induction hob while it is on.
Practically, this means induction hobs are probably best avoided in favour of electric or gas hobs if you have a pacemaker.
5) Induction hobs can come with handy extras
You can pick up a Which? Best Buy induction hob for less than £250, but if you fancy pushing the boat out, look out for these features:
- Hob to hood wireless communication Your cooker hood detects what is being produced from the hob below and adjusts its fan speed accordingly.
- Integrated extractor An extractor fan is built into the hob itself, meaning you won’t need a hood.
- Gas and induction in one If you can’t say goodbye to gas, some induction hobs also include a gas burner.
- Induction wok zone This is where the hob has a curved indentation to accommodate a wok.
