The heating efficiency of domestic induction heaters, electric resistance heaters, domestic geysers, and microwave ovens is fundamentally based on their energy consumption measured in kilowatt-hours (kWh). According to user russ_watters, all non-heat pump electric heaters, including electric resistance heaters, operate at an efficiency of 100%. This means that for heating 1 liter of water, the energy consumed will be equivalent to the energy output, making these methods efficient in terms of energy usage.
PREREQUISITESThis discussion is beneficial for homeowners, energy efficiency advocates, and anyone interested in comparing the energy consumption of various domestic heating appliances.

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?
