What is the heating efficiency of a domestic induction heater as compared to a simple electrical heater and microwave oven? Please give comparison on the basis of Kilowatt hour consumed.

"russ_watters has just replied-Any non heat pump electric heater has an efficiency of 100%."
Let me put my problem clearly: If I heat up 1 litre of water by 4 means- induction cook top, electric resistance heater, domestic geyser and microwave oven, then what kilowatt hour will I consume?

What is the context of the question? Is this for schoolwork?
