Savings and Research Tips Commercial woks & burners · energy & conservation · advisory only Click or tap here to expandClick here or ✕ to collapse

Why woks belong in energy monitoring. Wok lines combine high instantaneous power, frequent idle gaps, and heavy ventilation loads. The Greenways dashboard helps you see whether spikes reflect real covers or preventable flame-on / standby waste—before you commit to capex.

The efficiency gap (why bills diverge)

Fuel → food, not → kitchen air

Open-flame gas wok burners typically convert only about 30–35% of purchased gas energy into heat that actually cooks food; the rest heats the room and drives extraction demand. That gap is the main “free lunch” for operational fixes and equipment upgrades. Third-party comparisons often cite induction utilisation in the 90%+ range at the hob—still validate against your tariff, menu, and duty cycle.

Woks & burners — quick orientation

Professional kitchens pair woks with burners shaped for the pan: high output, often multi-hole or ring / jet / duck style heads on dedicated ranges. Round-bottom woks suit traditional cup-style burners; flat-bottom woks sit on a wider set of surfaces, including many induction units—always confirm cookware compatibility. Buyer guides typically distinguish low-pressure vs high-pressure gas burners (wide BTU spans), stockpot burners, integrated wok ranges, and waterless designs that reduce energy spent cooling with water decks. Historical context from traditional charcoal through gas to modern efficiency-led equipment also supports this transition framing.

Design details such as the black steel containment ring around the wok well can support efficiency by keeping more hot gases focused around the pan envelope, instead of spilling rapidly into ambient room air. In practical terms, this supports faster heat transfer to the cookware and can reduce avoidable burner-on time at service peaks—especially when combined with disciplined flame settings and strong maintenance.

Fuel pathways at a glance

Path	Heating model	Indicative efficiency (literature)	Energy / ops note
Gas wok (open flame)	Flame → air + pan	~30–35% to food (often quoted)	Strong hood & make-up air; idle flame expensive.
Electric (element / hotplate)	Element → plate → pan	~50–55% (typical teaching range)	Slower response than gas/induction for some menus.
Induction wok	EM field → pan directly	~90–95% (vendor / trade articles)	Requires ferrous woks; pan detection can trim idle draw.

Numbers are industry ballparks for planning—meter your own line and normalise for service intensity.

Sustainable accessory alternatives (for non-oven wok lines)

Because Greenways does not currently sell full wok ovens, this deep-dive comparison focuses on practical accessories and burner components that can improve gas and water efficiency while extending the life of your existing line.

Wok ring or flame concentrator accessory

Wok ring / flame concentrator

Focuses flame toward the wok base to reduce side-wall heat loss. This improves heat transfer efficiency and usually cuts burner-on time.

Typical gas saving: ~10–25%

High-efficiency wok burner assembly

Improved burner head geometry and airflow mixing keep usable heat wrapped around the pan for stronger combustion and less wasted flame.

Typical gas saving: ~15–30%

Pressure regulation & control kit

Helps keep flame output stable and appliances operating inside target pressure ranges. Better control supports consistent combustion and avoids over-firing.

Typical gas saving: ~5–12%

High-efficiency wok bowl / jet setup

Modern bowl and jet designs improve thermal containment and can reduce unnecessary cooling or rinse demand around the station.

Gas + water efficiency uplift (site dependent)

Combined upgrades are often where the strongest results appear. In many kitchens, pairing a focused flame ring with an efficient burner design can deliver ~20–40% total gas reduction, plus faster response and better control.

Conserve energy on the line (no capex)

Low-cost discipline improvements often deliver the fastest savings before any equipment upgrade.

Flame / power discipline: avoid leaving burners active when no pan is cooking.
Match burner to wok: right-size heat input to reduce overspill losses.
Batch & thaw: align prep to reduce heat spent defrosting on-line.
Jet & drain maintenance: keep injectors clean to avoid longer cycles.
Pilots & ignition: standing pilots can add a constant baseline cost.

Ventilation & HVAC (secondary savings)

After reducing open-flame intensity, ventilation optimisation can unlock additional electricity savings.

Review hood airflow: check whether extraction can be right-sized safely.
Check make-up air balance: avoid unnecessary fan and comfort penalties.
Recommission after changes: confirm settings under real service conditions.
Track post-change trends: verify sustained savings against pre-change baseline.

Priority summary

Window	Action	Typical cost	Impact (guide)

Savings and Research Tips HVAC & ventilation · Aeroseal duct sealing · advisory only Click or tap here to expandClick here or ✕ to collapse

Aeroseal duct sealing — what you should know

What it is. Aeroseal is an automated duct-sealing approach used in residential and commercial buildings. A certified technician pressurises the duct network and introduces a specialised, low-toxicity aerosol sealant. Sealant particles are carried to leakage paths and accumulate at the edges of gaps, forming a lasting seal from the inside — without coating the entire duct surface.

In practical terms for your team: instead of patching obvious leaks only, the process targets leakage across the tested system more systematically.

Why it can matter for your restaurant

Commercial kitchens often run extraction and ventilation for many hours each day — sometimes alongside comfort cooling or heating. Industry studies commonly cite substantial duct leakage in commercial buildings (order-of-magnitude ~30% of conditioned or moved air in some inventories). Hidden leakage means fans and plant work harder, comfort can drift, and energy spend rises even when hoods “look” correctly sized.

If you operate high-duty extraction (including gas-flame-intensive lines such as traditional wok cooking), reducing duct leakage may help extraction and HVAC interact more efficiently. Your savings will depend on your current leakage, airflow design, tariff, controls, and how much of the leakage is reachable and testable.

Sealed duct paths can trim fan-energy waste and unrelated heating/cooling burdens where leaks were forcing oversized airflow or conditioning. Any gas heating savings are site-specific.

How the process typically works

Technicians isolate and pressurise the duct sections included in scope.
A fine aerosol travels through the ducts; polymer particles adhere first at leakage edges rather than uniformly lining the duct.
For many commercial scopes, onsite work commonly completes within a compact window — your contractor should clarify shutdowns or access arrangements.

Outcomes operators often cite (sanity-check with modelling)

In European benchmarking material, leakage rates have reportedly been reduced by very large percentages in studied projects — your facility may differ sharply. Contractors and regional studies may quote wide ranges (roughly 20–40% savings on HVAC or fan-energy components in some retrofit narratives). Treat every figure below as a planning guide; validate with blower-door / duct-testing baselines before and after, and reconcile against your metering.

The Netherlands — is Aeroseal available?

Yes, Aeroseal has been marketed in European markets since the mid‑2010s. Documented sealing projects span many countries across the region.

To identify a contractor for your postcode, review the distributor’s locator on aeroseal.com/europe (typically “Find a Pro” style search by country).

Complementary actions (alongside Aeroseal)

Equipment door seals: Have your crew routinely inspect oven doors, refrigerators, steamers and hot-hold chambers — softened gaskets inflate electrical and thermal bills.
Kitchen hood filters: Grease-loaded filters increase static pressure — fans escalate kWh demand. Maintain a disciplined clean/replace rhythm consistent with manufacturers and fire-safety regimes.
Fresh-air and air-handling filters: Follow service intervals where appropriate; clogged media adds fan load across the broader plant.

At-a-glance summary

Measure	What it targets	Indicative impact (guides only)
Aeroseal (duct scope)	Systematic sealing of leaky duct seams and joints where included in programme	Contractors often cite ≈20–40% HVAC or fan-energy reduction potential — meter to verify
Gaskets & appliance doors	Stem thermal bleed from cooking and refrigeration openings	Typical housekeeping gains on the order of a few percentage points for affected equipment cohorts — varies widely
Filter maintenance	Hold down fan watts by reducing needless pressure drops	Commonly referenced ≈5–10% band on marginal fan-energy where filters were overdue — inspect your trend data

Figures summarise industry marketing and tertiary studies — they are not a guarantee for your site. Commission a leakage survey, agree scope with a certified Aeroseal partner, then compare half-hourly or daily energy before versus after normalization for weather covers.

If you would like support finding a Netherlands-based certified installer, scoping leakage testing, or building a concise payback appendix for landlords or investors, ask your usual Greenways contact and we will line up next steps.
