Does Using the Heater in Winter Consume More Fuel?

[Teagan]

Using the car's heater in winter does not consume additional fuel. The warm air from the car's heating system comes from the heat generated by the engine during operation, which is essentially waste heat recycling. The working principle of the car's heater is as follows: After the engine's cooling system dissipates heat from the engine, a fan directs this waste heat into the cabin to provide warm air. The functions of the car's air conditioning system include: 1. Regulating and maintaining optimal temperature, humidity, air cleanliness, and airflow within the vehicle cabin. 2. Providing a comfortable environment for passengers, reducing travel fatigue. 3. Creating favorable working conditions for the driver to ensure safe driving.
