Stellar vs Haven Range Specs
Oven capacity
The COSMO 30-Inch Haven Electric Convection Range offers 4.8 cubic feet of interior space. The COSMO Stellar Collection model provides 4.9 cubic feet. This half-cubic-foot difference allows the Stellar to accommodate slightly larger roasts or multiple baking sheets at once. Both ovens use a convection fan to distribute heat evenly, which helps eliminate cold spots. This feature ensures food cooks more uniformly and often at lower temperatures than standard ovens. For most home cooks, both capacities are generous. However, if you frequently prepare large holiday meals or need extra room for big turkey roasts, the Stellar’s extra volume provides a practical advantage for stacking or fitting bulky items.
Burner power
The Stellar Collection features significantly more powerful dual-element burners. Its main burner delivers 3700 watts total, with a 2500-watt 8.75-inch element and a 1200-watt 5.5-inch element. The second dual burner provides 3200 watts, split between 2200 watts and 1000 watts. In contrast, the Haven’s main dual burner totals 3000 watts, using two 1500-watt elements. The Haven’s other two burners are 1200 watts each. Higher wattage means faster boiling and quicker searing. If you often boil water rapidly or sear steaks at high heat, the Stellar’s burners offer more immediate thermal output. The Haven’s burners are adequate but less intense.
Cooktop surface
The Haven uses a ceramic glass cooktop, while the Stellar uses a black glass surface. Both materials provide a smooth, flat cooking area that is easy to wipe clean. The Haven’s stainless steel exterior matches its ceramic top, creating a uniform look. The Stellar’s matte black finish contrasts with its black glass top for a sleek, modern aesthetic. Ceramic glass is known for durability and scratch resistance. Black glass can show white residue or dust more easily but hides food splatters better. Your choice here depends on whether you prefer the classic stainless look of the Haven or the contemporary matte black style of the Stellar. Both surfaces function identically for daily cooking.
Physical dimensions
The Haven measures 29.9 inches wide, 27 inches deep, and 36.1 inches high. The Stellar is slightly wider in depth at 27.6 inches and taller at 37.1 inches. Both are 30 inches wide, fitting standard kitchen cutouts. The Stellar’s extra depth and height may affect clearance under overhead cabinets or with adjacent appliances. The Haven’s lower profile and shallower depth might fit better in tighter kitchens. If your kitchen has limited vertical space or shallow counters, the Haven’s smaller footprint is advantageous. Always measure your available space carefully, as the Stellar’s increased height and depth require more room around the unit for proper ventilation and door opening.
Weight and build
The Haven weighs 190 pounds, while the Stellar weighs 148 pounds. The Haven’s higher weight suggests a heavier internal construction or more substantial materials in its body. Both ranges feature heavy-duty knobs and matching oven door handles. The Haven is described as having corrosion-resistant stainless steel construction. The Stellar uses a matte black finish. Heavier appliances may feel more solid and stable during use. The lighter Stellar is easier to move during installation or cleaning. Both models include triple-thick oven glass and cool-to-touch handles for safety. If you prioritize a robust, heavy-duty feel, the Haven’s weight indicates sturdier build quality. The Stellar is lighter but still built for daily use.
Which COSMO 30-Inch Range Is Right For You
You want maximum oven capacity
The Stellar Collection offers 4.9 cubic feet of oven space, which is slightly larger than the Haven’s 4.8 cubic feet. This extra half-cubic-foot volume helps when you need to roast larger cuts of meat or bake multiple trays of cookies at once. The additional interior room provides more flexibility for bulky cookware and larger meal preparations.
You prefer a stainless steel finish
The Haven Collection features a stainless steel exterior that complements traditional kitchen designs. It uses a ceramic glass cooktop with a 3000W total dual element burner and two 1200W burners. This model weighs 190 pounds, suggesting a sturdy build. The stainless steel finish offers a classic look that resists corrosion and matches other stainless appliances.
You want faster cooktop heating
The Stellar Collection includes two dual-element burners with higher wattage: a 3700W burner and a 3200W burner. These provide more power than the Haven’s 3000W dual element. The larger 8.75-inch elements heat up faster and handle high-heat tasks more effectively. If you frequently sear meats or boil water quickly, these higher wattage burners offer a practical advantage.
