Gas vs Induction Wok Burner: Which for Your Kitchen? | 2026

Wok cooking asks more of an appliance than almost anything else in a commercial kitchen. Wok hei — the seared, faintly smoky character of a properly cooked stir-fry — depends on getting a carbon-steel wok extremely hot and keeping it there while cold ingredients hit it in quick succession. A standard gas cooktop burner cannot do it. A domestic burner is not remotely close.

This guide covers how to choose a commercial wok burner for an Australian kitchen: why wok burners are a distinct category, the gas versus induction decision that is genuinely live in 2026, sizing by ring configuration and kW, and the ventilation and compliance requirements that make wok installation more demanding than any other cooking appliance.

Gas vs induction wok burner — which should you choose?

Gas remains the default for traditional high-volume Asian cooking: very high output, instant visible control, flame contact up the wok walls, and it works with any wok. The costs are enormous radiant heat in the kitchen, a heavy extraction load and gas compliance obligations.

Induction has become a genuine alternative rather than a compromise. Energy goes directly into the wok, so far less waste heat reaches the room and the extraction requirement drops substantially. It needs a ferrous wok matched to the unit's bowl and a serious electrical supply, often three-phase — but on sites with no gas, or kitchens where heat load is a real problem, it is frequently the better answer.

Why a wok burner is not just a big burner

Three things distinguish a proper wok burner:

• Heat output. Commercial wok burners deliver far higher gas input than standard cooktop burners, concentrated into a small area. That intensity is what lets a wok recover temperature the instant cold protein or vegetables land in it.
• Ring geometry. A wok burner uses concentric jet rings that direct flame up and around the curved base of the wok rather than at a flat pan bottom. The flame pattern matches the vessel — which is why a wok on a flat burner heats only a small central spot.
• The wok well. A recessed ring the wok sits into, holding it stable and close to the flame while the burner heats the sides as well as the base.

Put a wok on a standard four-burner cooktop and you get a hot centre and cool walls — which means ingredients steam rather than sear. That is the whole difference.

Gas vs induction wok

This decision has changed materially in the last few years, and both options are now credible.

Gas wok burners remain the traditional choice:

• Very high output with instant, visible control.
• Flame contact up the wok walls, which many chefs consider essential to genuine wok character.
• Works with any wok, in any material, regardless of base.
• Trade-offs: enormous radiant heat into the kitchen, heavy ventilation demand, gas compliance obligations, and lower energy efficiency — a large proportion of the heat goes past the wok, not into it.

Induction woks have become a serious alternative:

• Energy transfers directly into the wok, so far less waste heat radiates into the kitchen — a genuine difference to working conditions in an Asian kitchen, which is often the hottest room in hospitality.
• Dramatically lower extraction load, because you are removing cooking vapour rather than vapour plus a wall of burner heat.
• Precise, repeatable power control and instant response.
• Viable where gas is unavailable or not permitted — increasingly common in new tenancies and shopping-centre fit-outs.
• Trade-offs: requires an induction-compatible (ferrous) wok with a base matched to the unit's bowl, generally higher purchase cost, and substantial electrical supply — commonly three-phase.

Commercial Kitchen Appliances stocks both: gas wok burners and ranges from brands including Jasper, Gasmax, Benchstar and Complete, alongside dedicated IWOK induction wok units in single and double configurations.

The honest guidance: if you have gas and your extraction is engineered for it, gas remains the default for traditional high-volume Asian cooking. If you are fitting out a site with no gas, a tenancy that prohibits it, or a kitchen where heat load and staff comfort are real problems, induction is now a genuine answer rather than a compromise. Our broader induction cooking range covers the wider category.

Sizing — burners, rings and kW

Wok ranges are specified by number of wok positions and output per position.

• Single-hole ranges suit small kitchens, secondary stations and venues where wok cooking supports rather than drives the menu.
• Two-hole ranges are the common workhorse for Asian restaurants — one chef can run two woks, or two chefs work side by side at peak.
• Three- and four-hole ranges serve high-volume operations where multiple woks run continuously through service.

Ring configuration within each position matters as much as the headline figure. Burners are commonly built as multiple concentric rings — a centre ring plus one or more outer rings — sometimes with independent control so a chef can run gentle heat for a sauce or full output for searing from the same position.

Size to simultaneous woks at peak. A kitchen that needs three woks running at 7:30pm on a Friday needs three positions; there is no way to time-share a wok station during a rush.

Wok well diameter and wok compatibility

Match the well to the woks you actually use. A wok too small for the well sits low and unstable; a wok too large sits high above the flame and never reaches temperature properly. Check the stated well diameter against your wok sizes before ordering, and remember that a kitchen typically runs more than one wok size.

For induction units the requirement is stricter — the wok must be ferrous and its curvature must match the induction bowl for efficient coupling. Many induction wok units are supplied with, or specify, a matching wok; the IWOK range includes matched wok vessels for this reason.

Water-cooled rims, waste and plumbing

Traditional gas wok ranges are frequently built as water-cooled units. A continuous trickle of water runs across the top deck around the wok wells, which:

• Keeps the deck surface cool enough to work on and touch safely.
• Continuously washes spills, oil and debris off the deck into a waste channel.
• Makes end-of-service cleaning far quicker.

Water-cooled ranges need a water supply and a waste connection, usually with a swirl tap or swivel tap over each well for rinsing woks between dishes. That means plumbing in the fit-out — factor it in early, because retrofitting a drain to a wok range position is expensive.

Dry-deck ranges avoid the plumbing but the deck gets very hot and cleaning is more work. For a busy Asian kitchen, water-cooled is generally worth the installation complexity.

Ventilation — the biggest extraction load in the kitchen

A gas wok range is typically the single highest heat- and vapour-load appliance in any commercial kitchen. High-output burners, open flame around a curved vessel, and rapid oil vaporisation produce enormous quantities of hot, grease-laden air.

What follows from that:

• Extraction must be engineered for the wok range specifically. A canopy adequate for a standard cookline will not necessarily cope with a wok range added beneath it.
• Make-up air matters. Extracting large volumes without adequate replacement air causes negative pressure — which shows up as doors that are hard to open, burners that don't draw properly and extraction that underperforms.
• Filters load fast. Wok cooking deposits grease heavily. Filter cleaning needs to be frequent and scheduled, and it is a fire-safety matter as much as a hygiene one.

Our commercial kitchen ventilation guide covers the compliance framework, the exhaust canopy buying guide covers specifying the canopy, and commercial kitchen fire safety covers the risk side. Have extraction assessed by a qualified person before you commit to a wok range.

Gas type and installation

Wok burners are configured for natural gas or LPG and are not interchangeable as supplied. Confirm your gas type when ordering.

Because of their high input rating, wok ranges also demand a gas supply capable of delivering that volume alongside everything else in the kitchen. An undersized supply line means every gas appliance underperforms once the kitchen is fully firing — a frustrating and expensive problem to diagnose after fit-out. Installation must be by a licensed gas fitter; see our commercial gas installation guide.

Induction wok units need a substantial electrical supply, frequently three-phase. Have a licensed electrician confirm capacity before ordering.

Which setup for which kitchen

• Chinese restaurant, high volume. Two- or three-hole water-cooled gas wok range with high output per position and engineered extraction. The core of the kitchen.
• Thai, Vietnamese or Malaysian kitchen. Two-hole gas range, with an adjacent burner for stocks and curries.
• Food court or shopping-centre tenancy. Check gas availability first — many tenancies restrict it. Induction wok units are frequently the practical answer, with the added benefit of much lower extraction demand.
• Pub, bistro or hotel adding an Asian line. Single-hole gas or a benchtop induction wok, sized to a supporting menu rather than a primary one.
• Kitchen with heat-load or staff-comfort problems. Induction is worth serious costing — the reduction in radiant heat is substantial.

Ready to choose your wok burner?

Settle gas versus induction against your site's gas availability and extraction capacity first — that decision drives everything else. Size on simultaneous woks at peak, match well diameter to your actual woks, and budget for plumbing if you want a water-cooled deck. Above all, get extraction assessed before you order.

Frequently asked questions

Why can't I use a normal gas cooktop burner for wok cooking?

A standard cooktop burner produces a flat flame pattern designed for flat-bottomed pans, and much lower output than a wok burner. On a curved wok it heats only a small area of the base, leaving the walls comparatively cool, so ingredients steam rather than sear. A wok burner uses concentric jet rings that direct high-output flame up around the curved surface, plus a recessed well that holds the wok close to the heat.

Is an induction wok as good as a gas wok burner?

For most purposes it is now genuinely competitive. Induction transfers energy directly into the wok, giving precise control, instant response and far less waste heat in the kitchen — which also substantially reduces extraction load. Gas still offers flame contact up the wok walls that many chefs prefer for traditional wok character, and works with any wok. Induction requires a ferrous wok matched to the unit's bowl and a substantial electrical supply, often three-phase.

What is a water-cooled wok range?

A water-cooled wok range runs a continuous trickle of water across the top deck around the wok wells. This keeps the working surface cool enough to touch, continuously washes oil and debris into a waste channel, and makes end-of-service cleaning much faster. It requires a water supply and waste connection, so the plumbing needs to be planned into the fit-out rather than retrofitted.

How many wok positions do I need?

Size to the number of woks running simultaneously at your busiest point, since a wok station cannot be time-shared during a rush. Single-hole ranges suit small kitchens and supporting menus; two-hole ranges are the common workhorse for Asian restaurants; three- and four-hole ranges suit high-volume operations with multiple chefs on the line.

Does a wok range need special ventilation?

Yes — a gas wok range is typically the highest heat- and grease-load appliance in a commercial kitchen, and extraction must be engineered specifically for it. A canopy adequate for a standard cookline will not necessarily cope. Make-up air must be adequate too, or negative pressure will undermine both extraction and burner performance. Have a qualified person assess extraction before committing to a wok range.

Can a wok burner run on LPG?

Yes — wok burners are supplied configured for either natural gas or LPG, and you specify which when ordering. The two are not interchangeable as delivered. Because wok burners have high input ratings, also confirm that the supply can deliver adequate volume alongside the rest of the kitchen's gas appliances. Installation must be carried out by a licensed gas fitter.
