The PTC heater is a self-regulating heating element, characterized by high efficiency, safety and durability. PTC heaters are used in many industries and devices. Find out how exactly a PTC heater works, what heating efficiency it has and how to create the most compact and efficient heat source based on it.

How does a PTC heater work?
Heaters are an extensive category of heating solutions. They belong to the heating elements of technical devices. The PTC heater is a specific type of electric heater whose operating principle is different from all other types of heaters. It contains polycrystalline ceramic material enriched with barium titanate. PTC heating elements are located in a compact, compact aluminum housing. The characteristic feature is the opposite arrangement of metallic coatings that act as electrodes.
PTC heaters operate on the principle of self-regulation, which in practice means that they automatically change the power depending on the prevailing temperature (the heat received from the surface of the PTC heating element is decisive). They don't run at maximum power all the time. As the temperature increases, the power decreases until a certain point. PTC components, thanks to their unique self-regulating property, are extremely universal in use and allow:
effectively reduce the electricity consumption of devices - the heater consumes only the amount of electricity necessary;
- better protect the natural environment by optimizing the use of resources;
- obtain a heat source with an excellent efficiency to size ratio;
- avoid using devices responsible for temperature regulation (although sometimes
- the use of an additional thermostat may be advisable).
The PTC heater is widely used as a heat source, among others. In:
- refrigeration equipment,
- recuperators,
- control cabinets (prevent moisture accumulation),
- air curtains,
- bathroom radiators,
- fluid and air heaters in vehicles,
Depending on the purpose, the PTC heater can operate in air or water. In the latter case, special design solutions prevent it from moving and heating up in the tank.
What is the heating efficiency of a PTC heater?
In the technical specifications of each PTC heater you can find information about its power. This parameter has a significant impact on the heating efficiency (efficiency/efficiency) of the device. You can choose from PTC heaters with different heating power. At the Onninen electrical wholesaler you will find heaters equipped with a PTC heating element with a heating power at 20°C:
-
10W, - 20W,
- 60W,
- 100W,
- 150W,
- 250 W
Choosing a PTC heater with the appropriate power allows you to fully use its potential, but this parameter must correspond to the efficiency of the heating device to ensure operational efficiency and safety. The power of the heater with the PTC self-regulating element cannot exceed the power of the equipment!
Individual heater models also differ in size, type of voltage, operating voltage, operating temperature range and additional equipment.
