The present invention relates to a heating system having a self-regulating heating element, wherein the temperature can be accurately controlled within a particular temperature range and be uniformly maintained with the self-regulating heating element which can temporally self-regulate power and temperature, and the power usage can be significantly reduced as the water temperature can be sustained with only a minimum of power supply when the water has heated beyond a set boiling point. The heating system comprises: a casing having an air inlet and an air outlet through which the outside air enters and exits, respectively; a self-regulating heating element (SR heating element), which is disposed in the interior of the casing, formed from a hardened paste mixture of an electrical resistance material, an insulation binder and a temperature control material, generates heat with supplied power, and self-regulates the temperature so that the temperature is uniformly maintained within a defined range; a controller for controlling the temperature of the generated heat by controlling the power applied to the SR heating element; and a discharge means, which is disposed near the SR heating element, for sucking in the air through the air inlet, and after bringing the sucked-in air into contact with the SR heating element, and discharging the heated air through the air outlet. |
