Induction cooking: what is it & how does it work?

Induction Cooktops have made a huge entrance into the world of kitchen appliances. Having gained popularity for its quick cooking times, energy efficiency, and safety, it’s pretty much the best of everything.

How does induction cooking work? Should you consider making the cooktop change? With all the big brands, from Asko and Bosch to Miele and Smeg coming up with new and improved technological advancements in induction cooking, here’s what you need to know if you’re thinking of making the switch. Read on for all the ins and outs of induction cooktops and why they could be the perfect match for your household.

What is induction cooking?

Traditional gas or electric cooktops rely on thermal conduction – creating an open flame or heating an element, which then heats your pan. Induction cooking completely eliminates the middleman. By using copper coils beneath the ceramic glass, it creates powerful electromagnetism that heats your compatible cookware directly.

What are the benefits of induction cooking?

Sceptical about cooking with magnets? Don’t be, says Tania Grillinzoni, The Good Guys Buyer – Cooking.

“Because the technology heats the pan directly rather than the cooktop, the heat-up speed of induction cooktops is unmatched,” says Tania. “You can boil water in record time and drop from a fierce sear to a delicate melt instantly – giving you absolute precision control.

“And the daily practical benefits are the real winner for busy households. Induction cooking can help with energy efficiency – and because the cooktop glass stays cool, it’s completely safe for little hands. Best of all? Spills don’t bake or burn onto the surface, so you just wipe and go.”

What cookware works on an induction cooktop?

Thinking of making the switch? You’ll have to check if your existing cookware is compatible with an induction cooktop. Anything with a ferrous base (for example iron, cast iron, magnetic stainless steel and enamelled cast iron) is typically compatible. 

“One of the biggest hesitations people have about upgrading to induction is the fear of having to buy all new pots and pans,” says Tania.

 “But in reality, many Aussies already own compatible cookware without even realising it. My top tip before you shop? Just raid your fridge for a magnet and take it to your kitchen drawers. Place the magnet on the base of your pan or pot and if it sticks, your cookware is suitable for induction.”

Here’s a quick breakdown of what works and what doesn’t:

^{*Note: Aluminium and copper pans will only work on induction if the manufacturer has specifically added a bonded magnetic steel plate to the bottom of the pan.}

Do I need an electrician to install an induction cooktop?

Yes, you will need a licensed electrician to hardwire and install almost all built-in induction cooktops. This is because induction cooktops deliver immense speed, and many models require a dedicated, high-amperage electrical circuit. 

However, if you want to avoid an electrical upgrade during your kitchen renovation, perhaps consider one of these alternatives:

• Both the Haier 500 Series 60cm Induction Cooktop and the Haier 300 Series 90cm Induction Cooktop are low current, which means these powerhouses might work with your existing wiring.**

• Similarly, the Westinghouse Powerlite induction cooktop range is designed with low input power that shouldn’t require rewiring for installation.**

• Try a portable induction cooktop. The Good Guys stocks a range of induction cooktops that plug directly into your wall and sit on your benchtop – perfect for a quick upgrade in your rental or for camping!

FAQs

Are induction cooktops safe, and how does the magnetic field affect you? 

Induction cooktops are exceptionally safe. The magnetic field is strictly concentrated directly above the copper coil and drops off dramatically just a few centimetres away. However, if you have a pacemaker, Australian health authorities such as Energy Victoria recommend consulting your cardiologist before making the switch to induction.

Do induction cooktops use more or less electricity than electric cooktops?

Induction cooktops use significantly less electricity than standard radiant electric models. Because the electromagnetic field heats the pan directly, most of the energy generated goes straight into cooking your food. 

How should I clean my induction cooktop?

Cleaning an induction cooktop is incredibly easy. Because the glass surface stays relatively cool during cooking, rogue oil splatters and spills won’t bake or crust onto the hob. Simply wait for the zones to turn off, then wipe the surface clean with a damp microfibre cloth and gentle glass spray.

What should I look for when choosing an induction cooktop for my small kitchen?

For a compact kitchen, prioritise a 30cm, 60cm or portable induction cooktop to maximise limited bench space.
