Thermador range terminology
Understanding Thermador range terminology helps you make informed decisions about purchase, use, and repair. This glossary covers the most important terms specific to Thermador ranges.
Burner and cooktop terms
- Star Burner: Thermador’s patented five-pointed gas burner design delivering 56% more flame coverage than round burners. The star shape eliminates cold spots.
- ExtraLow: Star Burner simmer capability down to approximately 100°F — precise enough to melt chocolate without scorching.
- BTU (British Thermal Unit): Measures burner heat output. Thermador Star Burners range from 6,000 BTU (simmer) to 22,000 BTU (power wok burner).
- Wok burner: High-output central burner (22,000 BTU on Professional models) designed for high-heat stir-frying with a wok ring accessory.
- Sealed burner: Burner design where the flame ports are sealed against the cooktop surface, preventing spills from reaching internal components.
Oven terms
- True Convection: Convection system with a dedicated third heating element (ring element) behind the fan, providing even heat without rack rotation.
- Dual fuel: Range with gas cooktop burners and electric convection oven — combining gas responsiveness with electric oven precision.
- Self-clean: High-temperature oven cycle (800-900°F) that incinerates food residue to ash. Use sparingly — no more than 3-4 times per year.
Collection terms
- Professional: Bold commercial-inspired design with heavy-duty knobs and 10″ backguard requirement.
- Pro Harmony: Flush-mount design sitting level with standard 36″ countertops — no backguard modification needed.
- Pro Grand: Flagship 48″ and 60″ ranges with griddle, steam oven, warming drawer, and up to 8 Star Burners.
