Abstract

The invention relates to a self-regulating heating circuit comprising at least one resistive element (43) having a substantially temperature independent resistance (R) and at least one PTC element (44) having a temperature dependent resistance (R). These elements (43, 44) are arranged in heat transfer relationship with a flowing medium of a heat circuit. The characteristics of the PTC element(s) (44) are selected such that when the temperature of the flowing medium reaches a predetermined value, the resistance of the PTC element(s) (R) has reached a level such that the voltage across the resistive element(s) drops. The resistive and PTC elements (43, 44) are coupled to each other in a configuration such that the combined power delivered by the resistive element(s) and PTC element(s) (43, 44) is reduced when the resistance of the PTC element(s) (R) has reached said level.
