An induction heater for a cooking surface. The induction heater includes an electrically insulating layer, at least one inductor defining a winding adapted to heat at least one cooking utensil, at least one sensor adapted to detect whether the at least one cooking utensil is placed above the cooking surface, and at least one magnetic flux concentrator. The at least one inductor and the at least one sensor are arranged on the electrically insulating layer. That layer is interposed between the at least one inductor and the at least one magnetic flux concentrator.

Induction heater for a cooktop

A method and device for detecting the amount of limescale that accumulates in liquid heating devices, in particular for heating water. The method is capable of establishing, through simple temperature measurements, if the amount of limescale deposited on the heater element of a device for heating liquids is such as to jeopardize the correct operation thereof and provides the user with information on the need to clean the aforesaid heater.

Method and device for detecting the amount of limescale in liquid heating devices

An induction heater for a cook top comprising: —a first electrically insulating sheet (); —a second electrically insulating sheet (); —one or more inductors () arranged on a same plane between the first sheet () and the second sheet (), each inductor () comprising a single electrically conductive track defining a flat spiral coil; —at least one magnetic flux concentrator () arranged on a plane under the second sheet (); —a metallic heat sink plate () arranged under the at least one magnetic flux concentrator (), adapted to dissipate the heat produced by the one or more inductors ().

Induction heater for a cooking surface

An electric heater including a metal body, in which a first pipe and a second pipe are provided in the metal body. The first pipe and second pipe are mutually distinct so as to be crossed by two distinct flows of fluid to be heated. A first heating stretch, a second heating stretch and a third heating stretch are arranged in the metal body. The first pipe and the second pipe are arranged between the first heating stretch and the second heating stretch. The third heating stretch is proximal to the second pipe and distal from the first pipe. The second pipe is arranged between the first pipe and the third heating stretch.
