I suspect that the 12KW isn't to a single burner, but rather the total across all burners. A typical home gas range is probably totalling 17kW or so with all burners going. doing some research in the internet, the large burners on induction cook tops do about 3.5kW, with less common 11" burners getting up to 4kW or so. The large burners on a gas stove do about 17500 BTU, which is about 5kW. I could believe that the power transfers more efficiently on an induction stove as the pot itself heats up. Maybe it's enough to balance out to roughly equivalent to gas, and a 12kW induction range sounds like a nice convenience. I would bet that you aren't boiling your water as fast as you think you are relative to a gas burner though. :-)

  The operating cost is generally lower for gas as well. It's certainly true where I live, where 1 kWh is seemingly something like $0.40 after all the rates, fees and taxes. Is your gas stove in your new place nice or is it kinda cheap? I've certainly used plenty of mediocre gas burners. I would expect a high end induction stove to be a better experience than a low end gas burner. I think we can all agree that electric coil burners are terrible.

Induction ranges are ~ 2x more energy efficient than resistive, since there’s no loss of heat between the heater coil and pan. I just switched from gas to induction, and am consistently surprised at how cool the area around the pan stays vs. with natural gas. I’d guess the gas burner is wasting at least half the heat it puts off. A 5kW gas burner is definitely delivering less heat to the pan than a 4 kW induction burner. Induction has other disadvantages though. The most obvious is that the bottom of the pan has to be perfectly flat, and match the burner size (at least for most burners). Lots of specialty cookware fails that requirement (magnetic or not).

  Ah, cool. Looking up efficiencies, it looks like induction is about 80% vs. gas about 40%. So that puts output power at 2.5kW for a large induction burner vs 2kW for a large gas burner. So I suppose you could boil water slightly faster with a nice induction stove, assuming good heat transfer on both.
