Stellar vs Nebula Range Specs

Fuel type

Edge: Tie

The COSMO 30-Inch Electric Convection Range uses electric power. It requires a 240V connection with either a 3-wire or 4-wire setup. You must ensure your home has the correct electrical outlet before installation. In contrast, the COSMO 30-Inch 5-Burner Gas Convection Range runs on gas. It includes a 120V/60Hz plug for ignition and controls. The Nebula model also supports liquid propane, though the conversion kit is sold separately. Your choice depends entirely on your existing kitchen infrastructure. You cannot swap fuel types without significant utility modifications. This is a fundamental difference that dictates compatibility with your home.

Number of burners

Edge: COSMO 30-Inch 5-Burner Gas Convection Range

The Stellar model features four burners on its glass cooktop. This includes two dual-element burners and two single-element burners. The dual elements offer variable heat zones within a single burner. The Nebula model provides five sealed gas burners. This extra burner gives you more simultaneous cooking options. You can use all five spots at once without crowding. The Stellar range limits you to four items on the cooktop. For large families or frequent entertainers, the additional burner on the Nebula model offers practical flexibility. The Stellar design focuses on dual-element versatility rather than raw count.

Burner type

Edge: Tie

The Stellar range uses dual-element and single-element electric burners. The dual elements combine a 2500W/2200W outer ring with a 1200W/1000W inner ring. This allows for precise heat control on a glass surface. The Nebula range uses sealed gas burners. These range from 3,500 BTU for simmering to 18,000 BTU for high-heat boiling. Sealed burners are easier to clean because spills cannot fall underneath. Gas burners provide immediate visual feedback and instant heat adjustment. Electric elements take longer to heat up and cool down. Your cooking style determines which burner type suits your needs better.

Oven capacity

Edge: COSMO 30-Inch 5-Burner Gas Convection Range

The Stellar model offers a 4.9 cubic foot oven cavity. This is a spacious interior suitable for most standard roasts and baking sheets. The Nebula model provides a slightly larger 5.0 cubic foot capacity. While the difference is only 0.1 cubic foot, it can accommodate slightly larger items or more trays. Both ovens feature convection fans for even heat distribution. The Nebula oven includes a 15,000 BTU bake burner and a 7,500 BTU broil burner. The Stellar oven relies on electric heating elements. The extra space in the Nebula model is a minor but measurable advantage for large batches.

Build material

Edge: Tie

The Stellar range features a matte black finish with a glass cooktop. It includes heavy-duty knobs and a matching oven door handle. The glass surface is easy to wipe clean but requires specific care to avoid scratches. The Nebula range is constructed from corrosion-resistant stainless steel. This material is durable and blends with other modern appliances. It also includes heavy-duty cast iron grates for heat retention. Stainless steel is generally more resistant to staining and discoloration over time. The Stellar model offers a distinct aesthetic choice with its black design. The Nebula model provides a classic stainless steel look that fits most kitchens.
