Thermador gas ranges, rangetops and cooktops that feature the patented "Star Burner" are sold in stores throughout the country, searchable by city and state or ZIP code via a dealer locator on the company website. These units are also available for purchase from appliance retail websites like AJMadison and Amazon.
Thermador's unique star-shaped burner features 35 natural gas ports spread out over 16.75 inches of perimeter, significantly more than the usual 28 ports on a 10.75 inch perimeter round range burner. The shape of the "Star Burner" reduces the area of the cold spot typically found in the center of the top of gas burners. Thermador's design delivers heat faster and more evenly across a variety of cookware sizes.
The "Star Burner" also has features like the "ExtraLow" system, which provides a lower possible burner temperature than many competitors. It functions by cycling the "Star Burner" on and off to maintain cooktop temperatures near 100 degrees Fahrenheit, ideal for low-heat simmering applications. The burners are a raised pedestal design, backed by a porcelain surface that is easily cleaned.
The "22K Power Burner," a variant of the "Star Burner," is featured on the Thermador Pro Grand Steam Range. It delivers 22,000 British thermal units of cooking power for quick boiling and better searing performance.
