Basically instantly? How do induction hobs defy the laws of physics? If the massive difference is the pan type, why isn't it almost instant with gas? Or do gas hobs output way way less energy than an induction hob? How many kilowatts is yours? |

On an induction hob, the heat is generated by the pan itself. That’s the instant part. The pan itself heats more or less quickly depending mostly on its mass and what it’s made of.
A gas hob is much less efficient in the way heat is transmitted to the pan: the flame irradiates everywhere, not only on the pan, and the air around the flame and the pan moves, carrying heat by convection.

A steel pan heats quickly because it’s light and thin. A cast iron pan heats slowly because it’s thick and heavy (kind of material also plays a role, but steel and cast iron are not too different in that respect).

Off the top of my head I think they are comparable. It’s just that most of this heat is wasted.
