The upper rim of the kettle is unheated and insulated. This reduces heat radiation and saves energy, also minimizing the risk of burn to the operator.
This design also ensures that the food does not burn in the kettle spout when the kettle is emptied, which would reduce the quality of the food and cause cleaning to take longer.
The tap makes it quick and easy to fill the kettle with water for cooking and cleaning.
The heating power is easily controlled by using the dial.
