Our verdict

A wide gas range with a large convection oven and heavy cast iron grates for busy home kitchens. Burner heat output is not listed, so serious searing needs are hard to judge before buying.

Overview

A home cook who wants a wide gas cooktop and a large oven gets a row of sealed burners over a convection cavity with a built-in fan. Heavy cast iron grates span the top, and knob controls run each burner and the oven.

Cooking room is what this Cosmo offers: a broad burner layout and a large fan convection oven in one stainless body. Burner heat ratings are missing from the listing. The listing also calls it both slide-in and freestanding, so confirm the cutout and gas line plan before ordering.

Who it's for

Large households that cook several pots at once get the most from the wide burner layout and big oven. Cooks who need published burner heat ratings, or kitchens without a gas supply, should look elsewhere.

Pros and cons

Pros
  • Six sealed burners on a wide cooktop
  • Large fan convection oven
  • Heavy cast iron grates included
  • Three chrome plate oven racks
Cons
  • Burner BTU ratings not listed
  • Only a one year limited warranty
  • Slide-in versus freestanding fit unclear in listing
  • Heavy unit, hard to move into place

Performance notes

Even baking depends on the convection fan moving hot air through the cavity, which reduces hot spots and shortens cooking times. Sealed burners trap spills on the cooktop surface instead of letting them drop below. Cast iron grates spread pan support across the top so heavy pots stay stable.

Frequently asked questions

Is the Cosmo COS-GRC366KB a slide-in or freestanding range?

The listing names slide-in as both form factor and installation type, while the mounting type reads freestanding. Check the side panels and backguard in the product photos and confirm your cutout before ordering.

Does the Cosmo Lumin gas range have a convection oven?

Yes. A built-in fan circulates heat through the oven, which the seller says reduces cooking times.
