How Does A Car Heater Work?
Heat Generated by the Engine
After the car is started, the engine will gradually warm up as it runs, generating a large amount of heat energy.
Coolant Absorbs Engine Heat
The coolant (also called antifreeze) inside the engine circulates under the drive of a water pump, which absorbs the heat generated by the engine and prevents it from overheating.
Hot coolant flows through the heater tank
The heat in the coolant is conducted to the heater core, a small radiator mounted inside the car.
The blower blows air through the heater core and into the cabin
The air blown by the blower passes through the heated heater core, thus becoming warm, and is then sent through the air vents into the vehicle to heat the interior.
FAQs For Car Heater
Why doesn't the heater produce hot air when the car first starts?
This is because car heaters rely on the heat of the engine coolant to heat the air. When you first start up, the engine temperature is still low and the coolant has not yet warmed up, so the heater cannot blow hot air immediately. It usually takes a few minutes of driving before it starts to warm up.
Does using a heater increase fuel consumption?
In conventional fuel vehicles, the interior heater mainly utilises the waste heat from engine operation, so it does not consume additional fuel and basically does not affect fuel consumption. However, electric vehicles or plug-in hybrids use an electric heating or heat pump system, which consumes electricity and may slightly affect range.
Do I need to run the heater on ‘internal’ or ‘external’ in the winter?
When you first start the car, we recommend using the ‘external circulation’ to bring in fresh dry air and speed up the defogging process.
After the cabin is warmed up, it is recommended to switch to ‘internal circulation’, which can keep the heat faster and save energy.
However, the two modes can be used alternately to prevent the air inside the car from being too dry or cloudy.
