Choose COSMO 30-Inch Electric Convection Range if
- You need extra oven space for large roasts or multiple dishes

Verdict: The 30-inch model offers significantly more oven capacity and convection features for serious home cooks.

30-Inch vs 24-Inch Range Specs
Width and footprint
The COSMO model measures 30 inches wide, specifically 29.9 inches in width, with a depth of 27.6 inches and a height of 37.1 inches. It weighs 148 pounds. The Avanti unit is 24 inches wide, with actual dimensions of 23.4 inches in width, 24.6 inches in length, and 40.7 inches in height. It weighs 116 pounds. The 30-inch range offers a wider cooking surface and a shorter, deeper profile. The 24-inch range is narrower but taller, fitting into smaller kitchen footprints while requiring more vertical clearance. You must check your cabinet space carefully for both dimensions.
Oven capacity
The COSMO electric range provides a spacious 4.9 cubic foot oven cavity. This larger volume accommodates big roasts, large casseroles, or multiple baking sheets simultaneously. The Avanti range offers a smaller 2.66 cubic foot oven. This capacity is suitable for smaller families or everyday meals but limits the size of dishes you can cook at once. The difference is nearly two cubic feet. If you frequently cook large meals or entertain guests, the larger oven in the 30-inch model is more practical. For solo cooking or small households, the smaller oven suffices.
Cooking features
The COSMO range includes a convection oven, which uses a fan to distribute heat evenly. This feature eliminates cold spots, allowing food to cook more evenly and often at lower temperatures. The Avanti range relies on standard bake and broil elements without convection. It lacks the forced air circulation that improves browning and cooking consistency. The COSMO also features dual-element burners for flexible heat control. The Avanti uses standard radiant elements. Convection is a significant advantage for versatile cooking, making the COSMO more capable for baking and roasting tasks.
Burner power
The COSMO 30-inch range features four burners with high power outputs. It includes two dual-element burners totaling 3700W and 3200W respectively, plus two 1200W single elements. This setup provides intense heat for boiling and searing. The Avanti 24-inch range has four radiant elements: two 1800W elements and two 1200W elements. While the COSMO offers higher peak wattage for rapid heating, the Avanti provides consistent radiant heat. The COSMO burners are more powerful, which is beneficial for quick boiling or high-heat searing. The Avanti burners are adequate for standard cooking tasks.
Safety and controls
The COSMO range features heavy-duty knobs and a cooling ventilation system for safe heat dissipation. It includes triple-thick oven glass and a cool-to-touch handle to prevent burns. The Avanti range uses a mechanical 60-minute kitchen timer with an audible bell. It includes a hot-surface indicator light and a removable storage drawer. The COSMO focuses on physical safety features like cool handles and ventilation. The Avanti emphasizes convenience with a timer and indicator light. Both designs address safety, but the COSMO offers more robust physical protection features for households with children.
Which range fits your needs
Large family cooks needing high capacity
The COSMO model offers a 4.9 cubic foot oven, providing ample space for large roasts and multiple dishes. Its dual-element burners deliver up to 3700 watts for rapid heating. You get convection cooking for even heat distribution. The 30-inch width accommodates bigger cookware, making it ideal for households preparing substantial meals regularly.
Apartment dwellers with limited counter space
The Avanti range measures just 24 inches wide, fitting snugly into smaller kitchens, condos, or ADUs. It weighs 116 pounds, making it lighter and easier to maneuver. The ceramic glass cooktop wipes clean easily. This compact footprint preserves valuable floor space while still delivering full electric cooking capabilities for daily use.
Users preferring simple mechanical controls
Avanti features a mechanical timer with an audible bell, offering straightforward operation without digital interfaces. The controls are easy to use for those who dislike complex electronics. The white finish and simple design suit minimalist decor. You get reliable bake and broil functions with temperatures up to 550°F, controlled via basic mechanical knobs.
Cookers wanting heavy-duty build quality
The COSMO range is built for durability with heavy-duty knobs and a matte black finish. It includes safety features like triple-thick oven glass and a cool-to-touch handle. The 148-pound weight suggests a sturdier construction. You benefit from an oven cavity cooling ventilation system and ETL listing for peace of mind during intense cooking sessions.

Frequently asked questions
Can a 24-inch range fit in a standard 30-inch space?
No, a 24-inch range will not fit in a standard 30-inch space. The Avanti unit measures 23.4 inches wide, leaving significant gaps on either side. This mismatch creates an unstable installation and exposes adjacent cabinetry to heat. You need a cutout that matches the appliance width exactly for safe operation.
Which size offers more oven capacity?
The 30-inch COSMO model provides more oven capacity. It features a 4.9 cubic foot interior, which accommodates large roasts and multiple dishes simultaneously. The 24-inch Avanti unit is designed for smaller spaces and lower volume cooking. If you frequently prepare large meals, the wider unit is the practical choice.
Do both ranges include convection baking?
The COSMO 30-inch range includes convection baking as a standard cooking feature. This function circulates hot air for even cooking. The provided data for the Avanti 24-inch range does not list convection capabilities. You should verify this specific feature in the Avanti manual or product sheet before purchasing.
How much weight do these units add to the floor?
The COSMO 30-inch range weighs 148 pounds. The Avanti 24-inch model weighs 116 pounds. The heavier COSMO unit requires a sturdy floor surface to support its mass. Ensure your flooring can handle the additional load, especially if it is a laminate or vinyl surface.
Are both models freestanding?
The Avanti 24-inch range is explicitly listed as a freestanding installation type. The COSMO 30-inch model is also designed for freestanding use in standard kitchen layouts. Both units sit independently on the floor. You do not need to build them into cabinetry for proper installation.
What burner options are available on the 30-inch model?
The COSMO 30-inch range features four burners. It includes dual-element burners that deliver up to 3700 watts for rapid heating. This setup allows for versatile stovetop cooking. The 24-inch Avanti model has fewer burners to match its smaller footprint.
Is a glass cooktop standard on both models?
The Avanti 24-inch range includes a glass cooktop, which aids in easy cleaning. The COSMO 30-inch model is described as an electric convection range, but the data does not specify the cooktop material. You should check the COSMO specifications to confirm if it also features a glass surface.
