How to Choose the Right Induction Cooktop

Why Induction Is the Fastest, Safest, and Most Efficient Cooktop Technology

Induction cooktops have become the premium choice in Australian kitchen renovations for good reason. They heat faster than gas or ceramic, use less energy, are the safest cooktop surface available, and are by far the easiest to clean. This guide covers what to look for when choosing an induction cooktop for your kitchen.

How Induction Works

Induction cooktops use electromagnetic coils beneath the glass surface to generate a magnetic field. When magnetic cookware is placed on the zone, an electrical current is induced directly in the base of the pan, generating heat inside the cookware itself. The cooktop glass surface does not heat up significantly — only the pan and its contents do. This makes induction the fastest and most energy-efficient cooktop technology available, with around 85 to 90 percent of energy going directly into the food.

Cookware Compatibility

Induction cooktops only work with cookware that has a magnetic base. To check your existing cookware, hold a fridge magnet to the base of each pot or pan — if it sticks firmly, the cookware is induction compatible. Cast iron, magnetic stainless steel, and cookware labelled induction-compatible all work. Aluminium, copper, glass, and non-magnetic stainless steel do not. If you need to replace cookware, factor this cost into your budget.

Key Features to Look For

Number of Zones

Standard 60 cm induction cooktops have four cooking zones. 90 cm models typically have five zones. The zone configuration matters as much as the number — a good layout includes a large zone (240 mm or more) for woks and large pots, medium zones for everyday pots and pans, and a small zone for saucepans. Some models include a flexible zone or bridge zone that combines two adjacent zones into one large cooking area for griddle pans and fish kettles.

Power Output per Zone

Induction zone output is measured in watts. Higher output means faster heating. Look for at least one zone with 3,000 to 3,700 watts or a boost function that delivers maximum output for fast boiling. Boost mode on a large induction zone can boil 2 litres of water in under 4 minutes.

Power Management

Many induction cooktops share power across zones — when multiple zones are on at high power simultaneously, the total draw is managed by cycling power between zones. Some premium models include a power management system that maintains full power to all active zones simultaneously. Check the total cooktop power draw (typically 7,200 to 9,000 watts) and confirm your kitchen's electrical circuit can support it. Larger cooktops typically require a dedicated 32-amp or 40-amp circuit installed by a licensed electrician.

Touch Controls

All induction cooktops use touch controls on the glass surface. Look for clear, intuitive controls with a lock function to prevent accidental changes during cooking. Slider or dial-style controls that allow quick, smooth power level adjustments are more convenient for experienced cooks than tap-to-step controls.

Safety Features

• Residual heat indicators: Display H on the zone when the glass is still hot after use, even though induction doesn't heat the glass significantly — important for safety awareness.
• Auto shut-off: Automatically turns off a zone if no cookware is detected for a set period.
• Child lock: Disables all controls to prevent accidental activation.
• Boil-over detection: Some models detect a boil-over event and pause the zone automatically.

Cleaning

The smooth glass surface wipes clean with a damp cloth. Spills don't bake onto the cool surface during cooking. Use an induction-specific glass cleaner and a soft cloth — avoid abrasive scrubbers that can scratch the surface.

What to Expect at Different Price Points

Mid-Range ($500 to $1,200)

Mid-range induction cooktops deliver reliable performance, good zone output, boost modes, and practical safety features. Most households will find an excellent model in this range.

Premium ($1,200 and Above)

Premium induction cooktops deliver the highest zone outputs, flexible bridge zones, full power management across all zones simultaneously, the most intuitive controls, and refined glass finishes.

Frequently Asked Questions

Is induction safe to use near a pacemaker?

People with pacemakers should consult their cardiologist before using an induction cooktop. The electromagnetic field produced by induction cooktops can in some circumstances affect older pacemaker models. Modern pacemakers are generally well shielded, but medical advice should be sought on an individual basis.

Does induction work with a cast iron pan?

Yes. Cast iron is one of the best materials for induction cooking. It has a naturally magnetic base and retains heat exceptionally well, making it ideal for searing, grilling, and slow cooking on induction zones.
