How It Works
Three Steps to Start Cooking
Most charcoal cookers require manual airflow management and mid-cook refuelling. The Gravity Series 1150 removes both. Load once, set your temperature, and cook without interruption.
1
Load the hopper
Fill the GravityFed hopper with lump charcoal or briquettes. The hopper holds up to 5.5 kg of lump charcoal or 8 kg of briquettes and feeds fuel down to the firebox continuously as it burns.
2
Light and set your temperature
Insert a pure paraffin fire starter for a clean light with no lighter fluid. Set your target temperature on the digital panel or the Masterbuilt app. The 1150 reaches 105°C in approximately 9 minutes and 370°C in approximately 15 minutes.
3
Cook without babysitting
The DigitalFan adjusts airflow automatically to hold your set temperature. No vent adjustment, no reloading mid-cook, no constant monitoring. Monitor up to 4 meat probes via the app from anywhere.
Cooking Capacity
Built for Large Gatherings
With 1,150 square inches of total cooking space across the main grate and two porcelain-coated warming racks, the 1150 handles serious volume without compromise.

What can I cook on the Gravity Series 1150? Everything from low-and-slow smoked brisket at 107°C through to high-heat searing at 371°C. Roast whole chickens, smoke ribs for 6 hours, bake with the lid closed, or sear steaks over direct heat. Add the Pizza Oven insert to expand further.

Key Features
What Makes the 1150 Work
GravityFed Charcoal Hopper
Holds up to 5.5 kg of lump charcoal or 8 kg of briquettes. As charcoal burns from the bottom, gravity feeds fresh fuel down from the hopper above. Up to 15 hours of cooking without reloading.
DigitalFan Temperature Control
A digitally controlled fan manages airflow from the hopper through to the cooking chamber. Set your temperature and the system maintains it automatically across the full 107°C to 371°C range.
Reversible Cast Iron Smoke and Sear Grates
One side optimised for high-heat searing, the other for low-and-slow where moisture retention matters. Cast iron holds and radiates heat evenly and is the preferred surface for serious charcoal cooking.
FuelSaver Dual-Wall Insulation
Dual-wall construction with porcelain-coated interior retains heat, smoke, and moisture inside the cooking chamber. Uses charcoal more efficiently and produces more consistent results across long cooks.
Masterbuilt App Control
Wi-Fi connected. Set temperature, adjust cook time, monitor up to 4 meat probes simultaneously, receive alerts, and access recipes from your phone. Manage the entire cook from inside the house.
Two Porcelain-Coated Warming Racks
Sit above the main grate for holding cooked food at temperature, running indirect cooks, or staging items during a larger cook.
Easy Cleanup
Removable ash bucket below the firebox. Front-access grease cup below the cooking chamber. Both remove and empty quickly after the cook.
Model Comparison
Gravity Series 600 vs 1150
Both models use the same GravityFed hopper system, cover the same temperature range, and include app control. The difference is cooking space and who you are cooking for.
| Specification | Gravity Series 600 | Gravity Series 1150 (this model) |
|---|---|---|
| Cooking space | 600 sq in | 1,150 sq in |
| Capacity | 5 racks ribs, 10 chickens | 12 racks ribs, 19 chickens |
| Max burn time | Up to 18 hours | Up to 15 hours |
| Reaches 105°C in | About 7 minutes | About 9 minutes |
| Temperature range | 107°C to 371°C | 107°C to 371°C |
| App control | Yes, up to 4 probes | Yes, up to 4 probes |
| Warranty | 1 year | 1 year |
| Model number | MB20041423 | MB20041625 |
| Best for | Smaller households | Regular entertaining and larger groups |
The 600 is the right choice for most regular backyard cooks. The 1150 makes sense when you regularly cook for larger groups or want to run the grill at full capacity without compromise. Both are available to view at our Wetherill Park showroom.
Model Comparison
Gravity Series 1150 vs XT
The Gravity Series XT is the step up from the 1150. Both use the GravityFed hopper and DigitalFan, cover 107°C to 371°C and include app control. The XT adds more cooking space, a longer quoted burn time, faster heat-up, stainless steel grates, racks and shelves, and a longer warranty.
| Specification | Gravity Series 1150 (this model) | Gravity Series XT |
|---|---|---|
| Cooking space | 1,150 sq in (0.74 m²) | 1,260 sq in (0.81 m²) |
| Capacity | 12 racks ribs, 19 chickens | 16 racks ribs, 20 chickens |
| Hopper | Up to 5.5 kg lump or 8 kg briquettes | Up to 5.5 kg lump or 8.2 kg briquettes |
| Max burn time | Up to 15 hours | Up to 24 hours |
| Heat-up | About 9 minutes to 105°C, 15 minutes to 370°C | About 7 minutes to 105°C, 11 minutes to 370°C |
| Cooking grates | Reversible cast iron | Reversible stainless steel |
| Warming racks | Two porcelain-coated racks | Up to three stainless steel racks |
| Grease management | Front-access grease cup | Full-body grease tray |
| Body | Dual-wall insulation with porcelain interior | FuelSaver single-piece body, dual-wall insulation, fibreglass mesh gasket |
| Size (W x L x H) | 138 x 67 x 132 cm | 155 x 84 x 132.5 cm |
| Warranty | 1 year | 3 years |
| Model number | MB20041625 | MB20043024 |
The 1150 suits regular entertaining when you want plenty of grate space in a more compact footprint. The XT makes sense if you want the longest unattended cooks, stainless steel cooking surfaces and a 3-year warranty. Figures are from Masterbuilt.

Care and Maintenance
Keeping It in Good Condition
- Remove ash from the bucket after each cook
- Empty the front-access grease cup regularly
- Brush the cast iron grates clean after use while still warm
- Use the shutdown slides to cut airflow and save unused charcoal at the end of a cook
- Use a cover when the unit is not in use, particularly for outdoor storage
- Re-season the cast iron grates periodically with a light coat of cooking oil
- Do not use harsh chemicals on the exterior or interior surfaces
1150 Questions
Masterbuilt 1150: Common Questions
How is the Gravity Series 1150 different from the 1050?
Going by Masterbuilt's own figures, the 1150 has 1,150 sq in of cooking space against 1,050 sq in on the 1050. The 1150 hopper holds up to 5.5 kg of lump charcoal or 8 kg of briquettes for up to 15 hours of cooking, while Masterbuilt quotes up to 4.5 kg of lump or 7.25 kg of briquettes and up to 10 hours for the 1050. Both cover 107°C to 371°C, use the GravityFed hopper and app control, and take the same Large cover. We sell the 1150, not the 1050. Compare the current models in our Gravity Series buyer's guide.
Is the Masterbuilt Gravity Series 1150 worth it?
It is worth it if you want real charcoal flavour with set-and-forget temperature control and you regularly cook for a crowd. Masterbuilt rates its 1,150 sq in for 12 racks of ribs or 19 chickens, with up to 15 hours per hopper load and a 107°C to 371°C range for smoking through to searing. If you mostly cook for four or fewer, the Gravity Series 600 is the better fit. If you want the longest burn time and stainless steel grates, look at the Gravity Series XT.
How much charcoal does the 1150 use per cook?
Masterbuilt does not publish a per-cook figure. It quotes a hopper that holds up to 5.5 kg of lump charcoal or 8 kg of briquettes for up to 15 hours of cooking. Masterbuilt recommends lump charcoal or briquettes, such as our Masterbuilt lumpwood charcoal. Charcoal use depends on your set temperature, the weather and how long you cook, and hotter cooks burn through charcoal faster. Insert the shutdown slides when you finish and any unused charcoal is saved for your next cook.
What cover fits the Gravity Series 1150?
The Masterbuilt Large Digital Charcoal Grill and Smoker Cover (MB20081220). Masterbuilt Australia lists it as fitting the Gravity Series 1150, XT and 1050, so one cover suits all three.
