A Thermador kitchen is more luxurious, more efficient and more beautiful than any other kitchen. Because for seven decades, Thermador has been at the forefront of fusing the art and science of design and ingenuity. From introducing the first built-in oven almost 50 years ago to revolutionizing gas cooktops with the patented Star Burner; and from designing the first retractable downdraft ventilation system to advancing speed cooking technology; Thermador has helped transform the American kitchen.

Thermador's electric cooktops offer today's most advanced features and the largest line of styles and element configurations for today's kitchen enthusiast. Choose from a variety of control types, including conventional knob designs and advanced mono-control interfaces. Element styles include ZoneSmart, which actually senses when cookware is placed on the element, and bridge elements to accommodate odd-sized or oblong pans - giving you more choices to match your cooking style.
