<p>Disclosed is an electric heating device comprising an electric radiator (10) heating the air which penetrates said radiator. The radiator is provided with a housing (12), at least one resistive element that is mounted in the housing and is formed by at least one zigzag-shaped metal ribbon (22) which is disposed such that said metal ribbon is directly exposed to the air penetrating the housing, and a circuit (30) controlling the electric power supplied to the resistive element(s) which is/are connected to a source of power. The electric radiator (10) comprises a set of individual heating modules (20) which are disposed parallel to each other inside the housing (12) and in such a way that said heating modules (20) are directly exposed to the air penetrating the housing. Each heating module (20) is provided with a folded or undular metal ribbon (22) and an electronic interrupter which is controlled by the control circuit (30) selectively blocking the supply of electric power to the metal ribbon (22).</p> |
