Why an electric water kettle when you can use your beautiful old-fashioned stove top teakettle? Water doesn't boil differently anyhow. The argument is energy savings! The Ibis water kettle boils 50 oz of water in less than 12 minutes using a 1500 watt power heating element directly in contact with the water. That means the energy enters the water without getting lost heating up the metal body of your traditional kettle.
