Does Car Heater Consume Fuel?

[StellaFitz]

Car heater does not consume fuel. Related introduction: 1. Working principle: When the engine coolant temperature is high, the coolant flows through the heat exchanger in the heating system (commonly known as the heater core), where it exchanges heat with the air delivered by the blower. The heated air is then blown into the car through various outlets by the blower. Therefore, using the heater does not consume fuel. 2. Knowledge expansion: In cold winters (even late autumn and early spring), the car heating system can provide warmth to the car interior, increasing the temperature inside. In winter, spring, and autumn, when the air humidity is high and there is a significant temperature difference between the inside and outside of the car, frost or fog may form on the window glass, affecting the driver's visibility and compromising driving safety. In such cases, turning on the heating system can help remove the frost or fog from the window glass.
