Standard vs Extra Large Gravity Feed Smoker: Which One Suits Your Commercial Kitchen?

If you're running a catering business, a restaurant kitchen or a butcher shop and looking to add low-and-slow smoked meat to what you offer, you've probably already landed on a gravity feed smoker as the answer. It's the setup that lets you load up, set your temperature and walk away, instead of babysitting a fire through a six-hour service. Whether you've been comparing commercial smokers Australia-wide or you've already decided on Flaming Coals, the real question is which size actually fits what you're running: the standard Gravity Feed Smoker, or the bigger Extra Large version built for genuinely high-volume work. Here's what actually changes between the two, plus the one accessory that makes either of them far easier to run.

What Makes a Gravity Feed Smoker Worth the Switch

A gravity feed smoker works by feeding charcoal down a vertical chute into the firebox as it burns, so you're not opening the lid every hour to add fuel or chase temperature swings. For a kitchen, that's the whole appeal: less staff time tied to the fire, more consistent results, and one less thing to go wrong mid-service. Both the standard and Extra Large Flaming Coals units run on this same gravity-fed principle, and both are built as a genuine commercial smoker rather than a backyard unit wearing a commercial price tag. Have a look at the full range of Flaming Coals gravity feed smokers if you want to see them side by side before reading on. The gap between the two comes down to scale.

The Standard Gravity Feed Smoker: Solid Capacity Without the Commercial Price Tag

The standard model gives you 170 litres of cooking space across four heavy-duty racks, expandable to seven if you need more room later. That's enough for eight large briskets or twelve shoulders in one cook, and on a single load of charcoal it'll hold temperature for up to 24 hours, so an overnight cook is genuinely hands-off. It's built from stainless steel, sits on oversized caster wheels so you can shift it around a kitchen or load it onto a trailer for an offsite event, and comes with the usual practical touches: an ash drawer for quick cleanup, an oversized water pan for moisture, and a side shelf for prep space.

As the lower-cost entry point into commercial-grade gravity feed cooking, the standard model is the one worth starting with if you're adding smoked product to the menu for the first time, running a smaller catering operation, or you're a serious enthusiast who wants commercial-grade build quality without paying for volume you won't use. This unit can sometimes be in stock, but it may also need to be specially ordered in. Therefore, allow some lead time and always plan ahead. 

The Extra Large Gravity Fed Smoker: Built for Volume

Step up to the Extra Large and you're looking at 340 litres of cooking space, five stainless steel racks across 20 adjustable positions, and room for up to 16 full-size briskets or 30 racks of ribs once you add the extra racks. It comes with the Flaming Coals Temp Master Pro built in, so temperature regulation is automated from the start rather than something you add on later.

One thing worth knowing before you commit: a full load only holds for around 6 hours, noticeably less than the standard unit's 24-hour run, so a busy all-day service means planning your refuelling rather than setting and forgetting overnight.

The build reflects the step up too: 1.5mm steel walls with 25mm insulation throughout, a 3-year warranty, and oversized casters despite the extra weight. It's special order only, and the extra capacity, insulation and warranty come at a higher cost than the standard model. The Extra Large is built for a commercial kitchen smoker that needs to move real volume, not for testing the waters.

Who actually buys the XL? Le Bistró de route, a busy commercial kitchen in Italy, chose the Extra Large specifically for its capacity to cook a lot more in a single load. When volume is the whole point, capacity matters more than the outlay.

Side by Side: What Actually Changes

The Accessory That Matters for Either One: Automatic Temperature Control

Whichever size you land on, there's one accessory worth adding on day one. An automatic smoker temperature control unit like the Tempmaster Pro reads the ambient temperature inside your smoker through a probe and adjusts fan speed automatically to hold your set point, with 3-stage fan control that slows down as you approach temperature instead of overshooting and spiking. For a kitchen running the smoker unattended through a service or overnight, that's the difference between checking in every hour and actually walking away.

The BSP Adapter version is built specifically to suit the female 2-inch BSP fitting on the standard Gravity Feed Smoker, so it's a straightforward add for that unit. The Extra Large already ships with its Temp Master Pro built in, so you won't need to buy this separately for that one. It's a small spend relative to the smoker itself, and it's the upgrade most owners say they should have bought from day one.

Rounding Out the Setup

A few smaller accessories are worth having ready before your first commercial cook:

• Grill rack: adds a direct-grilling surface to the smoker, handy for searing off items to order alongside your low-and-slow cooks.
• Side shelf: extra bench space right at the smoker, useful when you're plating or resting meat mid-service.
• Smoker cover: protects the unit if it lives outside or gets wheeled in and out of a loading dock.

None of these points above change the cooking capacity, but they make the day-to-day running of either smoker easier once it's earning its keep.

Common Questions About the Flaming Coals Gravity Feed Smoker Range

Can I run either smoker unattended overnight?

The standard Gravity Feed Smoker holds temperature for up to 24 hours on one load of charcoal, so an overnight cook is realistic. The Extra Large runs up to 6 hours per load, so overnight service means planning a refuel rather than a full set-and-forget. It is still common practice to check it every so often, to ensure nothing has gone wrong during that time. 

Does the Tempmaster Pro work with both models?

Yes. The Tempmaster Pro's BSP Adapter is built to suit the standard model's 2-inch BSP fitting. The Extra Large already comes with its own Temp Master Pro built in, so it doesn't need the separate unit.

What's the real difference in capacity between the two?

The standard model cooks up to 8 large briskets or 12 shoulders in a 170-litre chamber. The Extra Large steps up to 340 litres, handling up to 16 full-size briskets or 30 racks of ribs once you add the extra racks.

So Which One's Right for Your Kitchen?

If you're adding smoked meat to the menu for the first time, running a smaller catering operation, or want commercial-grade build quality without paying for volume you won't use, the standard Gravity Feed Smoker is the sensible starting point. If you're running a restaurant, high-volume catering business or butchery that needs to move serious weight through the smoker every service, the Extra Large is built for exactly that, and the built-in Temp Master Pro means you're not adding automation as an afterthought.

Either way, pair it with the TempMaster Pro (if you go standard) and the accessories above, and you've got a setup that can genuinely carry a commercial kitchen rather than just look the part.

Wrapping Up

Both these smokers do the same basic job: hands-off, consistent, low-and-slow cooking without a staff member babysitting a fire all day. Which one earns its spot in your kitchen comes down to how much volume you actually need to move, and for how long you need it to run unattended. Get that right and the rest of the decision makes itself.

Frequently Asked Questions About Gravity Feed Smokers

What Is the Difference Between the Flaming Coals Standard and Extra Large Gravity Feed Smokers?

The main difference is cooking capacity. The standard Flaming Coals Gravity Feed Smoker has a 170 litre cooking chamber and can cook up to 8 large briskets or 12 pork shoulders. The Extra Large Gravity Feed Smoker doubles the cooking space to 340 litres and can handle up to 16 full size briskets or around 30 racks of ribs with additional racks fitted.

Which Gravity Feed Smoker Is Best for a Commercial Kitchen?

The right gravity feed smoker depends mainly on how much food you need to cook at once. The standard model is well suited to smaller restaurants, caterers, butchers and businesses introducing smoked meat to their menu. The Extra Large model is designed for higher volume commercial kitchens that regularly need to cook large quantities of brisket, ribs, pork or other smoked meats.

How Long Does a Gravity Feed Smoker Run on One Load of Charcoal?

The standard Flaming Coals Gravity Feed Smoker can run for up to 24 hours on a single load of charcoal, depending on cooking temperature and conditions. The Extra Large Gravity Feed Smoker runs for up to approximately 6 hours per charcoal load, so longer commercial cooks may require refuelling.

Can You Leave a Gravity Feed Smoker Cooking Overnight?

Yes. Gravity feed smokers are designed to maintain a consistent cooking temperature while charcoal feeds gradually into the firebox. The standard Flaming Coals model can run for up to 24 hours per charcoal load, making it particularly suitable for overnight brisket, pork shoulder and low and slow cooks. An automatic temperature controller can provide additional temperature management.

Do Gravity Feed Smokers Need an Automatic Temperature Controller?

A gravity feed smoker can operate without an automatic controller, but a temperature controller makes maintaining your target cooking temperature easier. The Flaming Coals Temp Master Pro monitors the smoker temperature and automatically adjusts airflow through a fan. The standard smoker can be paired with a compatible Temp Master Pro, while the Extra Large model already includes one.

What Can You Cook in a Commercial Gravity Feed Smoker?

Commercial gravity feed smokers can be used for brisket, pork shoulder, ribs, pulled pork, chicken, sausages and other low and slow BBQ meats. Their large cooking chambers and steady charcoal fuel supply make them particularly useful for restaurants, caterers, butcher shops and food businesses that need to produce consistent smoked meat in larger quantities.

Is a Gravity Feed Smoker Good for Catering?

Yes. Gravity feed smokers are well suited to catering because they provide large cooking capacity without requiring constant fire management. The standard Flaming Coals model is easier to move and provides capacity for smaller catering operations, while the Extra Large model is better suited to businesses regularly catering for larger events or producing high volumes of smoked meat.
