Overview
Cosmo builds the Haven range around a wide sealed-burner gas cooktop with a mix of high, medium and low output burners. The convection oven uses fans to move hot air, and a removable backsplash lets it stand alone or slide in between cabinets.
Burner variety drives the case for it, with high output burners for searing beside low ones for delicate sauces, plus a large convection cavity for batch baking. Its wide footprint and heavy frame limit where it can go. Warranty coverage is short.
Who it's for
Home cooks with a wide cutout and a habit of running several pots at once get the most from the burner spread and oven size. Small kitchens, or anyone replacing a narrower range without remodeling, should look elsewhere.
Pros and cons
- Burner outputs span searing to delicate sauces
- Convection fans circulate oven air
- Removable backsplash allows slide-in installation
- LED-lit control knobs
- Wide unit needs a large cutout
- Heavy frame complicates delivery and install
- Short limited warranty term
- Not smart home compatible
Performance notes
Burner output decides how fast a pot boils and how low a sauce can simmer, and the mix here covers both ends. In the oven, convection fans push hot air around the food, which speeds cooking and evens browning across racks.
