Ceramic vs Induction Hobs – What’s The Difference?
I often have clients ask me this question: what is the difference between a ceramic and an induction hob? And I can see why – they look almost the same. It’s easy to get confused between the two and not know the main differences.
In this post, I’ll talk about the similarities and differences between ceramic and induction hobs, as well as the pros and cons of each.
Armed with this information, you’ll know which type of hob is right for you!
First things first, quick and simple, what are ceramic and induction hobs?
What Is A Ceramic Hob?
A ceramic hob is a cooker with a glass-topped heating element powered by electricity. It operates by heating through the glass and pot or pans that you are using, transferring heat into your food.
What Is An Induction Hob?
An induction hob is more complicated than a ceramic hob, using electromagnetism rather than gas or an electric heating element to heat up and cook food.
A high frequency alternating magnetic field is used to cook your food, activated through a tightly wound copper coil that is activated when electricity is turned on.
Rather than transferring heat directly, the current is what is passed to your pan for heating. This is then the heat that cooks your food.

The Similarities Between Ceramic And Induction Hobs
It’s the similarities between ceramic and induction hobs that cause the most confusion. Many similarities can make the two seem almost the same.
Ceramic and induction hobs can look almost identical.
They both have smooth, flat surfaces that are often made from toughened glass.
On this surface, there are usually circular zones marked out with a white line. These show the areas you can place your pans to heat them.
Ceramic and induction hobs are most often controlled with touch dials on the front edge of the appliance.
Most models of both hobs will also come with a lock and heat indicator features.
The lock is a child-safe feature that means the hob can’t be operated without first unlocking it.
The heat indicator is an alert that shows if a particular zone is still hot after use. This is so you know not to put anything on it – including hands!
Both ceramic and induction hobs are powered by electricity. Most models of both hobs will need a larger dedicated power supply.
However, if an additional power supply isn’t an option for you, there are a few ‘plug and play’ 13 amp options if you need them.

The Differences Between Ceramic And Induction Hobs
As ceramic hobs work by having a heating element underneath each zone, the whole area is heated. This means that heat is lost and wasted, making them less energy efficient than induction.
Due to this heat loss and the method of heating with an element, ceramic hobs are also slow to heat up and slow to cool down.
This makes temperature adjustments a challenge. It’s like with coals in a barbecue: once they’re hot, they’re hot for a long time.
On the other hand, induction hobs only heat the part of the surface that comes into contact with your pot or pan. It is much faster – even faster than gas.
This also means that induction is very safe. Because there is no heat leakage, you can put your hand next to a pan and you wouldn’t burn yourself.
Induction hobs also cool down much faster, as it is only the residual heat trapped in the glass that needs to cool, rather than an entire heating element.
Think of it like a lightbulb – even after you turn off the light, the bulb remains hot. That same kind of residual heat will remain in your induction hob surface.
Ceramic hobs are rapidly becoming, if they aren’t already, a thing of the past. As such, the features you find on ceramic hobs are minimal.
Induction hobs, on the other hand, are always being developed, with new features available on a regular basis.
From flexi or bridging zones to having a full-colour built-in display, if you’re looking for tech, induction’s the best bet.
Below are some of the more common features you can get with induction hobs.
Flexi-zone – The hob can combine two or more zones to create a larger cooking zone for bigger pans, baking dishes or griddles.
Hob to hood – Some induction hob models can pair with the same brand cooker hood and talk to one another. When you start cooking, the hood will automatically turn on and will adjust its power setting depending on how many zones are running and at what power level. Very cool.
Powerslide – This function creates different power settings across two zones of the hob. A higher (hotter) zone at one end which then gradually turns into a low (cooler) zone at the other, with a medium section in between. This is perfect for more nuanced cooking that requires precise temperatures.
With induction hobs, you need to use a magnetic pan to generate the electromagnetic reaction that will cook the food.
Pans that are made of or with ferrous metals, such as cast iron or magnetic stainless steel, will work. Any pans that don’t have this simply won’t work.
In contrast, any pan will work on a ceramic hob. So, if you have a lovely expensive set of pans that aren’t induction friendly, it can feel like a waste and be a costly exercise to replace them.
On the whole, induction hobs are more expensive than ceramic hobs. The additional features, economic design and built-in safety elements all make induction hobs a hot ticket item.
In contrast, ceramic hobs are on the out and often at the lower end of the market.
The price will, of course, depend on the brand and model/spec of the hob you buy.

As you can see, induction hobs tend to have more pros over their ceramic counterpart. It’s a newer product with better technology, which manufacturers are focusing on developing more these days.
So, should you never buy a ceramic hob? If you can, you should always go for induction over ceramic. However, if you are looking for a cheap hob that gets the job done, then a ceramic hob is an option.
Remember, induction is here to stay and will continue developing. This will help to bring the price down further over time.
