If you are shopping for a six-burner range with two ovens, you are likely planning serious cooking for a large family or a busy kitchen. The real question is not just how many burners you get, but whether the heat is powerful enough for wok-level stir-fries and whether both ovens can actually hold a holiday feast at the same time.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
6 burner gas stove with double oven models vary wildly in BTU output, oven size, and build weight, so here is how to match one to your cooking style.
Our Picks at a Glance
How To Choose The Best 6 Burner Gas Stove With Double Oven
The right range balances total BTU output, dual-oven capacity, and the physical dimensions of your kitchen cutout. Before you fall for a beautiful finish, measure your cutout and confirm whether your home runs on natural gas or liquid propane.
Check the Total BTU Output
Total BTU (British Thermal Units) tells you the combined heat of all burners at full power. A higher total means faster boiling and better wok action, but it also demands a stronger gas line, so confirm your supply can keep up before you commit.
Weigh Oven Capacity and Features
Double ovens are not always equal, so compare each cavity’s cubic feet and convection features. Compare the cubic feet of each cavity and look for convection fans that circulate heat for even bakes. A temperature probe and multiple rack positions make a real difference when you are roasting a turkey and baking sides at once.
Consider Weight and Installation
These are heavy appliances, so plan for delivery and installation logistics. A 148-pound unit is manageable for a standard delivery crew, but a 323-pound slide-in model may require extra hands and careful planning for doorways and floors. Always confirm the fuel type and any needed conversion kit before delivery day.

In‑Depth Reviews
1. AAOBOSI 48 Inch Professional Freestanding Double Gas Range Ovens
The home-kitchen powerhouse that pairs dual ovens with restaurant-grade cast iron grates.
This 48-inch freestanding range brings serious cooking power to a home setup, starting with a 93,000 BTU total output spread across six burners. You get five 12,000 BTU burners for everyday simmering, one 15,000 BTU burner for faster boils, and a single 18,000 BTU burner that handles high-heat wok tossing. The sealed burners include automatic flame failure protection, so the gas shuts off if a flame goes out, which helps prevent leaks.
The double ovens are the real story here, with a 2.8 cu. ft. cavity and a larger 5 cu. ft. cavity giving you 7 cubic feet of total baking space. Convection fans circulate heat for even bakes, and a temperature probe means you can monitor a roast without opening the door. Owners love that “the oven door seals shut and no heat escapes,” which keeps the kitchen cooler and the baking consistent. The triple insulated glass door and cool-touch handle also make it safer when you are checking on dinner.
It is built for flexibility. The range runs on propane from the start, but a gas converter lets you switch to natural gas, and it is CSA certified for safety. The removable cast iron grates are dishwasher-safe, which makes cleanup after a big cook far less painful. At 148 pounds, it is also far easier to install than the 323-pound slide-in COSMO model, making it a smarter fit for most home kitchens.
What wins people over
- Double ovens with convection fans and a temperature probe for even baking
- Dishwasher-safe cast iron grates simplify cleanup
- Converts between propane and natural gas with included kit
What to watch for
- Propane conversion kit must be confirmed in the box before delivery crew leaves
- Most powerful burner at 18,000 BTU is a step below true commercial output
Ideal for: Home cooks who want dual-oven convenience and strong burner heat without a commercial footprint.
Check before buying: Confirm the conversion kit is included if you run natural gas, as one shipment arrived incomplete.
2. Kratos 6 Burner 60″ Gas Range with 24″ Griddle
A tank-like 60-inch commercial beast that turns out high-volume cooking without flinching.
If you are running a busy kitchen, the Kratos is built for exactly that. It delivers a staggering 180,000 total BTU output across six burners, with each burner pushing 30,000 BTU — that is roughly double the per-burner power of the AAOBOSI’s top burner. The heavy-duty stainless steel body and six removable cast iron grates are designed to take constant daily abuse.
The 24-inch-wide griddle is a standout feature that the other two picks lack. Its 3/4-inch-thick stainless steel plate holds heat evenly across a wide surface, so you can run a full breakfast service of eggs, pancakes, and bacon all at once. “The six burners deliver strong, consistent heat,” as owners phrase it, making it easy to manage multiple pans through a dinner rush without hotspots.
Each of the two full-size ovens outputs 30,000 BTU and holds a temperature range from 250°F to 550°F, which gives you real flexibility for both slow roasts and high-heat bakes. This range runs on liquid propane only, with a 3/4-inch gas connection, so it is aimed squarely at commercial settings like restaurants, diners, and banquet halls. It is a serious commitment — the 60-inch width and 60.4-inch height make it the largest unit here by a wide margin compared to the AAOBOSI’s more compact 45-inch footprint.
Built for volume: The 180,000 total BTU and griddle make this the clear choice for high-volume service, while the AAOBOSI suits home flexibility.
Consider first: Liquid propane hookup with a 3/4-inch connection means this is not a drop-in residential swap.
Reach for this if: You run a commercial kitchen that needs relentless heat and a griddle for breakfast service.
Look elsewhere if: You want a home-friendly dual-fuel conversion or a compact footprint for a residential kitchen.
3. COSMO Haven 48 in. 7 cu ft 6 Burner Double Oven Gas Range
A slide-in showpiece with convection ovens and a 323-pound build that screams pro-grade.
The COSMO Haven is the premium statement piece of this lineup, with a slide-in design and a massive 323-pound weight that gives it a tank-like presence. It delivers 7 cubic feet of total oven capacity across a spacious 4.8 cu. ft. primary oven and a secondary cavity. Both ovens use a fan-assisted convection heating element, which moves hot air around the food to eliminate cold spots and bake more evenly.
The primary oven is a true workhorse, pairing a 22,000 BTU bake burner with a 14,000 BTU broil burner, while the secondary cavity brings its own 14,000 BTU bake burner. That means you can broil a steak while baking a casserole in the other oven at the same time. Safety is clearly a priority here — you get an oven cavity cooling ventilation system, overheating protection, triple-thick oven glass, and a cool-to-touch handle that helps prevent burns.
Owners consistently praise the build quality and appearance, calling it well-constructed and noting the cool blue accent lights on the knobs. However, there is an honest caveat: the burner reliability gets mixed feedback, with some owners reporting igniters that failed — one even replaced six igniters over roughly five years. At 323 pounds, it is also significantly heavier than the 148-pound AAOBOSI, so delivery and placement need serious planning.
Best in show: The convection ovens and cool-touch handle make this the most feature-rich pick for a serious home chef.
The trade-off: Burner reliability is the recurring gripe, and the hefty weight demands careful installation planning.
Choose this for: A luxury slide-in look with convection baking and a cool-touch handle in a spacious kitchen.
Think twice if: You want the lightest installation or the most bulletproof burner track record in this group.
Understanding the Specs
Total BTU Output
BTU, or British Thermal Units, measures the heat a burner produces. A higher total means faster boiling, better searing, and stronger wok heat. The AAOBOSI delivers 93,000 total BTU for home use, while the Kratos jumps to 180,000 total BTU for commercial demand.
Oven Capacity and Convection
Oven capacity is measured in cubic feet, with the AAOBOSI and COSMO each offering 7 cubic feet across two cavities. Convection fans circulate hot air for even baking, and a temperature probe lets you monitor doneness without opening the door.
Fuel Type and Conversion
Ranges can run on natural gas or liquid propane, and the two are not always interchangeable without a kit. The AAOBOSI includes its own gas converter, while the Kratos is strictly liquid propane with a 3/4-inch connection, so check your home supply before buying.
Weight and Installation
Weight matters more than you might think — the slide-in COSMO weighs 323 pounds, over twice the 148-pound AAOBOSI. Heavier units are more stable but harder to move through doorways and onto your floor, so measure your path carefully.
