Abstract
An ironing system () comprises an iron () with a soleplate () comprising an induction heatable material. The ironing system () further comprises a unit () that includes at least one induction coil () and a device (). The induction coil () charges the iron () whereas the device () detects the temperature of the soleplate () by sensing a change in current flowing through the induction coil () or by sensing a change in voltage across the induction coil (). The current or voltage changes as self inductance of the induction coil () changes with magnetic permeability of the soleplate () as a function of its temperature. The device () switches the induction coil () on or off depending on the detected temperature.
