Positive temperature coefficient (ptc) heater

A positive temperature coefficient (PTC) heater comprising a housing and at least one PTC heating element arranged within the housing, the at least one PTC heating element including:

• two electrode plates configured to be coupled to the housing such that heat is transferable therebetween and the two electrode plates are electrically insulated from the housing;
• a plurality of heating layers of a PTC material arranged between and electrically contacting the two electrode plates;
• and
• at least one electrically insulated heat conducting layer alternating arranged with the plurality of heating layers, the at least one heat conducting layer coupled to the plurality of heating layers in a heat transferring manner.
