The operation of a modern heating system in a vehicle

The heat inside the machine comes from the running motor. The movement of air along the entire heating system is due to the presence of a special pump. Antifreeze with an increased heating temperature gets into the radiator of a car stove. Heated air passes through antifreeze and enters the car interior at the required temperature. Antifreeze returns from the stove to the power unit.
