A typical car heater is "free" in the sense that the heat is generated using the engine coolant. An ICE-powered car as a small heat exchanger called the heater box in the passenger cabin. When the heater is on, a door opens and directs air through the heater box before being blown back into the cabin. As long as the car is running and the engine is hot, you get heat.
