The primary function of air conditioning is heating. Heating systems get installed in all automobiles. An extra electric heating device known as PTC gets put on the system in some transitory phases. So you’re probably wondering What is a PTC Heater In A Car.
Quick Answer: Positive temperature coefficient heaters get abbreviated as PTC. The heating element within a PTC heater has a positive temperature coefficient, and its resistance increases as the temperature rises. It brings efficiency and safety to electric vehicle heating systems.

What is a PTC Heater In A Car and Why Do You Need It?
PTC heaters feature self-regulating heaters that come in a variety of printed designs. They employ conductive inks placed on polymer-based surfaces instead of circuitry, wires, or carbon fiber components seen in conventional heaters.
This technology uniformly heats the object’s whole area and self-regulates to a specified temperature. It removes the danger of overheating. PTC innovation gets required for safer, faster, or more uniform heating applications.
How Does The PTC Heater Work?
Heating and electric vehicle’s cabin may be problematic because, unlike typical internal combustion engines, the amount of waste heat available is limited. As a result, electric car interior warmers with high voltage are necessary.
A high-speed Control Channel (CAN) protocol gets used to control PTC cabin heaters. It boosts the heat from the blower’s heat stream as a component of the warming, ventilating, and air conditioning (HVAC) system.
Ceramic PTC components have low resistance at room temperature, allowing direct current flow and extreme heat transfer. At high temperatures, the process gets inverted due to the increasing resistance of the ceramics stones, and substantially less heat is released by turning off the flow of current. It provides more control and a necessary safety measure to protect you from burning.
One of the extra safety precautions is a shielded heater pole for improved protection against high voltages. The fin shape of an air heater gives a little pressure loss when used alone with an encased heater rod.
It enables the blower to function at lower speeds, lowering air velocity and disturbance for the passengers. That is what a PTC heater in a vehicle is!
Features Of A PTC Heater
- It is possible to have many heating steps. Single-stage mini-heaters for dispersed heating areas get easily manufactured as strong four- or five-stage heaters using the electronic control.
- Double the thermal protection and twice the service life. In all high-output variations, the switching parts and PC boards get thermally isolated from one another, and the PTC electronics feature an excessive temperature cut-out.
- Reduced tooling manufacture time and shorter development timelines for customer-specific applications
- Tolerates external electric shock.
Which Vehicle Uses The PTC Heater?
A PTC heater, which is appropriate to each car’s safety and packaging criteria, offers a source of heat in an EV or PHEV where no exhaust fumes heat is available.
Benefits Of A PTC Heater
PTC heaters avoid all defects and challenges associated with wires, etching aluminum foil, or carbon fiber heaters. Overheating gets avoided because the PTC material serves as a sensor.
Each region on the heated surface retains its temperature. Because of the equal heat distribution, there are no cold or hot spots. PTC heaters are unharmed by folding, except with wire heaters, so do not overheat.
PTC heaters can survive mechanical abuses such as folding, creasing, and cutting. They’re also water-resistant, so they’ll endure for a long time. PTC heaters may well get built in any shape or size, with such an unlimited number of spots and cuts.
They can get joined in parallel to provide large-area heating demands. They can also get tailored to function with various ranges of temperature and power levels.
Types Of PTC Heater
- The warmth of the ceramic discs is communicated to the air all around the device using only a PTC air heating Extruded aluminum fins get widely used to transmit heat. PTC Fin Heaters are the popular name for this kind of air heater.
- A PTC fan heater employs an extruded fin with a hexagon pattern and merely a fan to improve the heat transfer rate. Forced air might also get sent through ducts or to another location, and fan heaters get used when heat needs to get supplied to several places or outlets.
Different uses of PTC Heater Other Than Used In A Car
Transportation: PTC heaters provide several advantages to the automobile and aerospace sectors. These devices offer a small, lightweight way to heat the cabins of planes and automobiles. PTC heaters are likely to be used in seats and steering wheel heaters to aircraft de-icers. air heaters PTC
Healthcare: Due to the excellent safety records of PTC heaters, medical workers routinely employ them for a range of purposes. PTC heaters are particularly effective under-body heaters for operating stations, gurneys, and beds.
Outdoor apparel producers can incorporate PTC heaters into various designs. Jackets, belts, socks, and gloves may all integrate PTC heaters due to their capability to run open-loopÂ
Food & beverage: PTC heaters may maintain stable temperatures in meals and fluids while they get transported or kept for later use. PTC heaters get used in various phases of the food processing and handling industry, including processing companies, food transportation, and restaurants.
Does the PTC Heater Burn Oxygen?
Heaters with modern PTC technology that is entirely safe for the consumers’ health don’t burn oxygen. Thus they are harmless for the users’ health.
Final Thought
It might be unpleasant to deal with unsafe and unreliable heaters. In short, When utilized in combination with the heater core, PTCs appear to self-regulate electrical heaters. They are employed in temperature control to compensate for a heat shortfall on high-efficiency engines.
They are often located just after the heater core or even in ducts. PTC heaters expand on earlier heater designs to deliver safe, power heating systems for big and small applications. These are long-lasting heaters that perform efficiently and are simple to maintain.
