Things to know about car heating in cold weather
In the cold of 9 - 12 degrees Celsius in the North, turning on the heating mode in the car is necessary. However, not everyone knows how to use this function properly.
Many people think that when the car door is closed, the temperature in the car is warm enough and there is no need for a heating system. They think that not turning on the heating system will help the car save fuel. However, this is a misconception. So, how to use the heating system in the car properly?
How does car air conditioning work?
Many people think that car air conditioners are two-way air conditioners like those in homes. They can adjust the temperature to cool or heat as they like. However, that is a misconception. Car air conditioners actually only have one cooling direction.

The heating system operates independently of the evaporator (only the fan is shared). The heating system will collect heat from the radiator after running through the engine. At this time, the temperature will be collected in the water, flowing through the pipe near the dashboard. At this time, the fan will blow the air heated from the water into the cabin to heat.
Turn on the heater when the car starts, the fan will not blow hot air immediately. Only when the car engine is hot enough (usually a few minutes after the car starts), the temperature will gradually increase.
High-end cars all have heating systems integrated in the seats, steering wheel, door handles... This system runs on electricity so in theory it does not consume much fuel.
When in heating mode is the A/C button on?
In fact, many car users still mistakenly think that turning on the heating mode still has to start from the A/C button. However, this is a mistake. The air conditioner in the car only has one cooling direction, not two-way air conditioning like the air conditioner in the family.
The heating system operates independently of the air conditioning (only the fan is shared). Therefore, when the heating mode is on, there is no need to turn on the A/C.
How to unfog car windows
In cold weather or in humid rainy conditions, the amount of water vapor in the car often condenses on the glass, causing the glass to fog up. De-fogging the glass also means releasing all the water vapor in the car.

Many people wonder whether to turn on the air conditioner or start the heating system. In fact, both of these methods can dry the glass. However, to dry the glass quickly, when starting the car, turn on the air conditioner in fan mode to blow all over the glass. After about 1 minute, the glass will be dry.
After the glass is dry, switch the air mode to the cabin. At this point, turning on the hot or cold mode depends on each person's needs.
Note when turning on the heating mode in the car
When turning on the heater, drivers should be careful not to let the temperature get much warmer than the outside temperature. According to health experts, just make sure the people in the car do not feel cold.
Before getting out of the car, turn off the heater to allow your body to adjust to the outside temperature. If the temperature inside the car is much higher than the outside temperature, it can lead to heat shock when you get out of the car.
