Plenty of appliance reviewers have compared gas to induction by measuring the time it takes each to boil the same amount of water. Induction wins every time. That doesn't prove it's better, just that it provides plenty of heat.
1W=3.41 BTU/hr. So a 3,700w induction burner is equivalent to a 12,700 BTU/hr burner. Sure, you can buy a range with a 15,000 or even 18,000 BTU/hr burner. But where is that heat energy going? Gas burners are about 50% efficient, while induction is about 90% efficient. So that 3,700W induction burner can heat water about as fast as a 22K BTU/hr gas burner.
Yep - just test that out.
The induction also beats out my old electric range.
It was a tie however with the electric kettle !
