How to Choose Based on the Characteristics of the Heater?


An electric heating element is a device specifically designed to convert electrical energy into heat. They are widely used in many fields, including industrial, household, medical and automotive. The working principle of the heater element is to convert electrical energy into thermal energy and dissipate heat through the surface of the heater to achieve the heating effect. This unique energy conversion method makes the electric heating element flexible, efficient and controllable, suitable for a variety of different application scenarios. Below I will give you detailed recommendations on several cost-effective heaters for heating elements.

What are the electric heating elements?

Polyimide Heater: Polyimide heater is one of the most common electrical heating elements in applications. It is composed of flexible materials and metal conductors for heating resistance wires, such as nickel-chromium alloy, iron-chromium-aluminum alloy, etc. When electric current passes through a conductor, resistance will be generated inside the conductor, and the resistance will generate heat inside the conductor, thus achieving the heating effect and converting electrical energy into thermal energy.

Transparent heater: The transparent heater is made of PET material and is 80% transparent unlike other heaters. However, the heating temperature of the transparent heater is slightly lower than the other two types, and it is mainly used in automobile glass and automobile mirrors. The surface of the product can be quickly heated by electric heating. The appropriate heater material can be selected according to the light transmittance requirements of your product.

Silicone rubber heater: Silicone rubber heaters are usually made of materials with good thermal conductivity. Silicone rubber has high temperature resistance. This heater is a sheet-like device composed of an external metal conductor and insulating material. When electric current passes through the conductor, the silicone rubber heater generates heat and transfers the heat to the product, which does not affect the heating effect even in harsh environments.

What are the characteristics of heater elements?

Efficiency: The heater element only converts electrical energy directly into heat energy during use, so the energy of the heater has a very high utilization rate. The above heaters are more efficient than other traditional heating methods.

Controllability: The temperature of the heater can be adjusted by installing a temperature control device to prevent damage to the product caused by continuous heating by the heater. This controllability gives the heater great flexibility in various applications and can meet different heating needs.

Uniform heating: The heater adopts evenly distributed heating circuits or surface heating methods, so it can achieve a more uniform heating effect.

Fast response: Heaters respond very quickly and when current is passed through, they produce heat almost instantly.

What are the common applications of electric heating elements?

Electric heating elements are widely used in various fields. Here are some common application areas:

Industrial Heating: Heater elements play an important role in many industrial heating processes. The continuous heating function of the heater is used in heating and dissolving furnaces, drying equipment, heat treatment devices and presses. Because heater elements utilize high energy and can meet precise temperature requirements, they are very popular in industrial equipment.

Home Heating: Heater elements in home heating applications. Heaters are used in electric kettles, induction cookers and floor heating systems. Provides a comfortable environment thanks to the quick response and controllability of the heater element, with smaller size and lower maintenance costs.

Medical field: Heater elements are also widely used in medical equipment. They are used in infusion pumps and light wave therapy. Electric heating elements can quickly and accurately control temperature in applications, providing therapeutic benefits to patients.

Automotive Industry: Heater elements are also widely used in the automotive industry. They are used in car seat heaters, window defrosters, engine preheaters and coolant heaters, among others. The heater element generates heat quickly, keeping the car operational even in harsh environments.


As a common heating element, heater has a wide range of application prospects.
