What's the difference between Sterno wick and gel fuel?

Wick fuel burns at a lower, steadier temperature for longer service periods and is resealable. Gel fuel ignites faster, burns hotter initially, and is better suited to shorter, high-heat applications. Wick is generally preferred for extended buffet service; gel for quick-setup stations.

How long does Sterno chafing fuel burn?

Sterno gel cans range from approximately 45 minutes (2-oz / 56.70 g) to 2 hours (6.84-oz / 193.91 g). Wick cans range from 2 hours to over 6 hours, depending on the formulation and can size. Check the product label for the specific burn-time rating.

How do you safely put out Sterno fuel?

Smother the flame by sliding the metal cap or a flat snuffer directly over the can's opening. Do not blow out the flame; this can scatter hot fuel. Allow the can to cool before handling or storing.

How many cans of Sterno go under a chafing dish?

Full-size (12″ × 20″ / 30.48 cm × 50.80 cm) chafing dishes typically use two fuel cans, one per fuel holder position on the chafer stand. Half-size chafers generally use one can. The number may vary by chafer model; check the manufacturer's recommendation for the specific unit in use.

Is Sterno SpeedHeat really flameless?

Yes. SpeedHeat generates heat through a flameless exothermic chemical reaction with no combustion, no open flame, and no water pan required.

Are Sterno candle lamps and flameless candles safe for use on the table?

Yes. Liquid-wax candle lamps use a non-toxic, low-flash-point fuel that burns cleanly and produces minimal soot, making them safe for enclosed dining rooms. Flameless rechargeable LED candles produce no heat, no flame, and no combustion byproducts, making them suitable for indoor or outdoor settings, including high-traffic areas and venues with strict fire codes.

Can you reuse or relight Sterno chafing fuel?

Wick fuel canisters can be extinguished by replacing the cap and relit for subsequent use, provided fuel remains in the can. But never attempt to refill any Sterno canister after it is spent.

Sterno: Chafing Fuel, Flameless Warming & Table Lighting for Foodservice

Sterno is the inventor of portable heating solutions and has been associated with canned fuels for more than a century. First developed by S. Sternau & Co. in 1914, the company is now a worldwide brand that keeps buffet food safely hot, dining tables beautifully lit, and outdoor operations smooth. Sterno fuels offer comfortable buffet sets and table-lighting programs with flameless use and SpeedHeat warming for caterers, banquet halls, hotels, restaurants, and event venues, helping them run a polished buffet service from setup to the last plate.

Chef's Deal carries Sterno's full range of chafing fuel, SpeedHeat flameless warming systems, chafing dishes and buffet sets, WindGuards and accessories, table lighting, insulated catering bags, butane stoves, kitchen torches, and EcoChoice hand sanitizer.

Why Sterno is the Catering Standard?

Sterno fuels enable food service operators to meet the temperature requirements for holding hot foods at 135 °F / 57 °C or above the danger zone for up to 6 hours, and its flameless SpeedHeat technology provides a reliable solution for locations that prohibit open flames.

Sterno Chafing Fuel & Food Warming

Sterno's food-warming lineup includes the wick and gel fuels, the flameless SpeedHeat system, perfect for drop-off catering and delivery, along with the stands, pans, and protective accessories needed to keep your buffet running smoothly and safely.

Wick Chafing Fuel

Sterno wick fuel features liquid fuel and a fiberglass or cotton wick that draws methanol or ethanol-blend fuel from a sealed steel or aluminum canister. This produces a steady, controllable flame that maintains chafing-dish water-pan temperatures throughout a service window. Sterno wick canisters are available in 2-hour, 4-hour, 5-hour, and 6-hour configurations, with 0.23-0.65 lb (0.10-0.29 kg) cans. The flame height on wick fuel is lower and more consistent than gel, making it preferable.

Gel (Ethanol) Chafing Fuel

Sterno gel fuel is made with a thickened ethanol or diethylene glycol base that ignites quickly and burns hot, making it the right choice for rapid heat-up and shorter service windows, typically 45 minutes to 2.25 hours. The gel format requires no wick and is available in 2.05-oz (58.12 g) and 6.84-oz (193.91 g) cans, with the smaller sizes suited to individual portion warmers and the larger to standard chafer stands. A 13-oz (368.54 g) can is available in bulk. Because gel burns at a higher initial temperature than Wick, it is well-suited for action stations and quick-turn banquet lines where food must reach serving temperature fast.

SpeedHeat Flameless Food Warming System

Sterno SpeedHeat is a flameless warming solution that generates heat through a controlled exothermic chemical reaction. A SpeedHeat kit consists of a warming tray with a reservoir and single-use heat packets (available in configurations rated for approximately 45 minutes to 2 hours of holding). You can start the heating process by placing the pack in the reservoir and filling it with water. SpeedHeat is ideal for use in delivery orders, prepacked sales, and catering applications. The SpeedHeat base can be used repeatedly until it wears out, but the heat pack requires refills.

Chafing Dishes, Chafer Stands & Buffet Sets

Sterno's product portfolio includes foldable wire and chalkboard chafer stands and chafer pans with lids, designed to work in direct pairing with its fuel line and featuring suitable Sterno slots. Wire chafing stands accept standard 12″ × 20″ (30.48 cm × 50.80 cm) (nominal) hotel pans with a depth of 4″ (10.16 cm) or 6″ (15.24 cm) and are available in foldable, stackable stainless steel finishes. Chalkboard chafer stands accommodate 12″ × 10″ (30.48 cm × 25.40 cm) and 12″ × 6.75″ (30.48 cm × 17.15 cm) inserts, respectively, for smaller buffet stations or portion-control service.

Chafer buffet sets are available in 22-wire chafer stands or 4 foldable stands with pans and lids.

Chafing Accessories – WindGuards, Lids & Fuel Holders

WindGuards are wood or steel panels that surround the fuel can and the gap between the chafer frame and the water pan, shielding the flame from cross-drafts that can reduce heat output or extinguish the fuel entirely. Sterno WindGuards measure 10.75 x 20 x 75 inches (27.31 x 50.80 x 190.50 cm) and are especially useful for outdoor events, tented receptions, and rooftop venues.

Sterno chafer lids are available in domed and flat models to retain heat in the food pan between service cycles, improving fuel efficiency. Domed models feature large openings to enable easy access for guests, facilitating service while preventing dust and other contaminants from entering. Dedicated fuel holders clip or slide into chafer frames to keep cans centered and stable beneath the water pan, preventing tipping during service.

Sterno Table Lighting & Ambiance

Sterno has a comprehensive table-lighting product collection with more than 100 styles of candle lamps, flameless and rechargeable candles, and liquid candle systems.

Candle Lamps & Holders

Sterno candle lamps use liquid-wax candles and are ideal for tabletop use in restaurants, hotels, and event venues. They are available in multiple forms, including cylinder, tulip, fluted, and globe, in heights ranging from approximately 3.25″ (8.26 cm) to 11″ (27.94 cm), with clear, white, amber, red, mosaic, or frosted chimney options. Burn times for liquid-wax candle lamps range from 8 to 100 hours, depending on the fuel cell capacity, making them economical for high-turnover dining rooms.

Flameless & Rechargeable Candles

Sterno's flameless candles include battery-powered and rechargeable LED tealights and pillar-style flameless candles that replicate the warm flicker of real candlelight without heat, wax drips, or fire risk. LED tealights are commonly sold in sets of 4 or 12, with individual units measuring approximately 1.5″ (3.81 cm) in diameter and 1.75″ (4.45 cm) in height. 12-pack sets include charging bases that accommodate 4, 6, or 12 units simultaneously. Programmable timers with 4-hour on/20-hour off or 6-hour on/18-hour off cycles allow venues to automate table lighting across dining shifts without staff intervention.

Liquid Candles & Fuel Cells

Liquid candle fuel cells are the consumable insert that powers Sterno's candle lamps. Sterno liquid candles offer 8- to 100-hour Softlight, making them perfect for hotels and restaurants that prefer monthly restocking over daily lamp maintenance.

Sterno Catering, Delivery & Hygiene

Sterno has insulated catering and delivery bags, portable butane stoves and kitchen torches, and Ecochoice hand sanitizer and dispensers.

Insulated Catering & Delivery Bags

Sterno insulated catering bags are engineered to maintain hot food above 135 °F (57 °C) and cold food below 41 °F (5 °C) during transport. Sterno bags are available in 15" x 23" (38.10 x 58.42 cm) and 16 "x 24" (40.64 x 60.96 cm) sizes to hold 3 to 6 full-size pans. They feature antimicrobial and leak-free construction to meet school nutrition carrier requirements.

Portable Butane Stoves & Kitchen Torches

Sterno portable butane stoves are compact single-burner units designed for tableside cooking, action stations, and catering setups where a fixed gas line is unavailable. Standard models accept 8-oz (226.80 g) butane canisters to deliver 10,000 to 15,000 BTUs, sufficient for 2-4 hours of tableside flambé, sauté, and crepe service.

Kitchen torches use the same butane canister format and are used for crème brûlée finishing, cheese toasting, meat searing, and meringue browning.

EcoChoice Hand Sanitizer & Dispensers

Sterno's EcoChoice hand sanitizer and dispenser lineup covers front- and back-of-house hygiene with 70% ethyl alcohol hand sanitizer in 8-oz (236.59 ml), 16-oz (473.18 ml), and 1-gallon (3.79 l) refill sizes, plus wall-mounted, countertop, and floor-standing dispenser stations compatible with both gel and foam formulations.

Consideration for Choosing Sterno Chafing Fuel

To choose the correct Sterno chafing fuel, consider the fuel type (gel vs. Wick), burn time, and flameless requirement.

Wick vs. Gel: Which Sterno Fuel to Use

Choose wick fuel when the service window exceeds two hours, when consistent temperature without attention is the priority, or when outdoor conditions make a resealable can preferable.
Choose gel fuel when setup speed is the priority, when the service window is 45 minutes to two hours, or when a high initial temperature is needed to quickly bring cold food up to a safe holding range.
Choose SpeedHeat for venues with no-open-flame rules, water-flooring restrictions, or remote-delivery catering where carrying lit fuel is impractical.

Matching Burn Time to Event Length

Sterno's fuel range covers service windows from approximately 45 minutes (small gel cans, 2.05-oz / 58.12 g) up to 6-plus hours (large wick cans, 7-oz / 198.45 g long-burn).

Fuel Type	Duration	Event/Service Type	Positioning Requirement
Small Gel Can (2.05-oz / 58.12 g)	~45 mins	Short Buffets / Tasting Stations	1 can per fuel holder position
Standard 2-hour Wick / Mid-size Gel Can	1.5–2 hours	Breakfast & Lunch Buffets	1 can per fuel holder position
4-hour Wick Can	3–4 hours	Standard Dinner Service	1 can per fuel holder position
6-hour Wick Can / Resealable Canisters	6+ hours	Extended Receptions / All-Day Corporate Events	1 can per fuel holder position

When to Choose Flameless SpeedHeat Instead

SpeedHeat is the correct choice when the venue prohibits open flames or when the accumulation of combustion products is dangerous (hospitals, schools, aircraft catering, event spaces with sprinkler-proximity rules).

Sterno Fuel Safety & Handling Basics

Sterno chafing fuels are flammable products that require standard operator precautions. Hence,

Always use chafing fuel in a well-ventilated area.
Never attempt to refuel a lit or hot canister.
Extinguish the flame first and allow the can to cool before handling.
To extinguish wick fuel, replace the metal cap or use a snuffer; never blow out the flame.
Gel fuel cans should be capped immediately after service.
Dispose of spent canisters according to local municipal waste guidelines and in accordance with the product Safety Data Sheet (SDS), available from Sterno's official website.
Store fuel cans in a cool, dry location away from heat sources and open flames.
