Have a look between a Thermador 5 burner induction and a pro gas range top. Induction is magnetic heat, and Professional is high output gas.
Which one is better?
Boil: Induction is faster to a boil than Pro.
Simmer: Although the Thermador has the extra low intermittent simmer at only 150 BTU (average for gas is 500), induction is still better as it provides even lower and instantaneous simmering.
Efficiency: Induction is 90% efficient, and gas is 60%. 40% of all gas escapes through the sides of the burner. This creates more heat and requires more venting.
Curb Appeal: The impressive looking gas unit.
