Abstract: A heating system having: i) at least one resistive heat element; ii) at least two terminals for receiving a grid voltage from a power grid, and iii) a controller for being connected to the terminals for receiving the grid voltage, the controller connected to the at least one resistive heat element and being configured for controlling a load current through the at least one resistive heat element, wherein the controller is configured controlling the load current though the at least one resistive heat element. The controller comprises an FCFO-bidirectional power switch connected in series with the at least one resistive element for controlling the load current that is received from the power grid. A method is for controlling the load current through the at least one resistive element, which applies a certain algorithm to avoid inrush current, shortens the length of a cold start and solves problems such as EML.

Abstract: A heat module for a flooring. The heat module has a stepping plate having a first side and a second side, at least one heat element arranged along the first side of the stepping plate, and a water impermeable insulator at the first side of the stepping plate. The at least one heat element is attached to the first side of the stepping plate so that emitted heat is directly conducted to the stepping plate.
