Induction vs Gas Cooking: Why Perth Chefs Are Making the Switch

Gas has been the default cooktop for decades. That's changing. Induction technology has caught up and, on most measures, passed gas entirely.

How Induction Cooking Works

Unlike gas or electric coil cooktops, induction uses electromagnetic fields to heat cookware directly. A copper coil beneath the glass surface creates a magnetic field that induces electric currents in compatible pots and pans, generating heat.

The Result?

• Instant heat: Water boils in half the time
• Precise control: Temperature changes happen immediately
• Cool surface: The cooktop itself stays relatively cool
• No wasted energy: Heat goes directly into the pan

The Health Argument

This is where gas has the most to answer for. Recent research shows real health impacts from burning gas indoors.

What Gas Cooking Releases Into Your Home

Every time you cook with gas, your kitchen fills with:

| Pollutant | Health Impact | Gas vs Induction | |-----------|---------------|------------------| | Nitrogen Dioxide (NO2) | Respiratory irritation, asthma triggers | Gas produces significant NO2; induction produces none | | Carbon Monoxide (CO) | Headaches, dizziness, dangerous at high levels | Gas produces CO; induction produces none | | Formaldehyde | Carcinogen, irritant | Gas produces formaldehyde; induction produces none | | Fine Particles (PM2.5) | Deep lung penetration, cardiovascular effects | Gas produces particles; induction produces none |

The Asthma Connection

A landmark Australian study found that 12% of childhood asthma cases could be attributed to gas cooking. Children in homes with gas stoves are 42% more likely to have asthma symptoms than those in homes without.

For a household with kids, switching to induction removes these pollutants from your kitchen entirely.

The Cooking Performance Comparison

Speed Test: Boiling 2 Litres of Water

• Gas: 8-10 minutes
• Electric coil: 10-12 minutes
• Induction: 4-5 minutes

Induction is nearly twice as fast as gas for this common cooking task.

Temperature Control

| Feature | Gas | Induction | |---------|-----|-----------| | Minimum heat | Low simmer difficult | Precise low simmer | | Maximum heat | Very high | Higher than gas | | Response time | 5-10 seconds | Instant | | Temperature precision | Approximate | Exact degree control |

More professional chefs now prefer induction for its precision. Melting chocolate, simmering sauces, and controlling caramelisation are easier with exact temperature control.

Safety Features

Induction cooktops offer safety advantages that gas simply can't match:

• No open flame: Reduced fire risk
• Cool surface: Won't burn if touched (heat is in the pan)
• Auto shut-off: Turns off if no pan detected
• Pan detection: Only heats when compatible cookware is present
• Timer integration: Automatic turn-off after set time

The Cost Comparison

Upfront Costs

| Item | Cost Range | |------|------------| | Basic induction cooktop | $300-800 | | Mid-range induction | $800-1,500 | | Premium induction | $1,500-4,000 | | New cookware (if needed) | $200-500 |

Running Costs (Annual)

For a household cooking 1-2 hours daily:

Gas Cooking:

• Gas usage: $150-250/year
• Gas supply charge: $350/year
• Total: $500-600/year

Induction Cooking:

• Electricity: $50-100/year
• No supply charge: $0
• Total: $50-100/year

Annual Savings with Induction: $400-550

When combined with solar panels, induction cooking becomes essentially free during daylight hours.

Common Concerns About Induction

"I'll need all new cookware"

Not necessarily. Induction works with any cookware that a magnet sticks to. This includes:

• Cast iron: Works perfectly
• Stainless steel: Most works (check with a magnet)
• Enameled cast iron: Works great
• Carbon steel: Excellent choice

You'll only need to replace:

• Aluminum pans
• Copper pans (unless they have a magnetic base)
• Some stainless steel (non-magnetic grades)

Most households can keep 60-80% of their existing cookware.

"I won't be able to char capsicums or use a wok"

Modern solutions exist:

• Charring: Use a kitchen torch or oven grill
• Wok cooking: Induction-compatible woks and wok adaptors are available
• Flat-bottom woks: Work perfectly on induction and are now standard in many commercial kitchens

"What about during blackouts?"

This is a legitimate consideration. Options include:

• Keep a small camping stove for emergencies
• Install a battery backup system
• Use a portable gas burner stored for emergencies

Most households experience only a few hours of blackouts per year, making this a minor inconvenience compared to the daily benefits.

"I love cooking with flame"

This is often more about familiarity than necessity. Most people who switch to induction find they prefer it within a few weeks. The instant response and precise control become intuitive quickly.

Making the Switch in WA

DIY-Friendly Options

If you have an existing electric cooktop:

• Simply swap it for an induction unit
• May require an electrician to verify circuit capacity
• Usually a half-day job

If You're Currently on Gas

You'll need:

1. Electrical circuit: An electrician to run a new circuit ($300-600)
2. Gas disconnection: Optional but recommended ($0-200)
3. New cooktop: The induction unit itself

Total installation cost: $400-1,000 beyond the cooktop price.

Rebates and Incentives

While there are currently no direct rebates for induction cooktops in WA, the savings come from:

• Eliminating gas supply charges
• Reduced energy costs (especially with solar)
• Potential to disconnect gas entirely and save $350+ annually

Portable Induction: Try Before You Buy

Not ready to commit? Try a portable induction hob first:

• Cost: $100-300
• Plugs into standard outlet
• Great for testing if you like induction cooking
• Useful as extra burner later

This lets you experience induction cooking without any permanent changes to your kitchen.

The Verdict

For most WA households, the switch from gas to induction makes financial and health sense:

| Factor | Winner | |--------|--------| | Cooking speed | Induction | | Temperature control | Induction | | Running costs | Induction | | Health/air quality | Induction | | Safety | Induction | | Works in blackouts | Gas | | Initial familiarity | Gas |

Most people adjust within a couple of weeks. Pair it with solar panels and induction cooking costs you almost nothing to run.
