PTC (Positive Temperature Coefficient) heaters are a type of electrical heating device that use the principle of positive temperature coefficient thermistors to generate heat. These devices are becoming increasingly popular in a variety of applications due to their efficiency, safety, and environmental benefits. In this article, we will explore the working principle of PTC heaters, their advantages, applications, and the reasons why they are a great choice for both residential and industrial heating needs.

    What is a PTC Heater?

    A PTC heater is a self-regulating heating element made from a ceramic material that increases its resistance as the temperature rises. The key feature of a PTC heater is its use of Positive Temperature Coefficient thermistors, which means that as the temperature of the device increases, its electrical resistance also increases. This unique characteristic helps to prevent overheating and provides the heater with the ability to maintain a consistent temperature without the need for a thermostat.
