Things to know about car heating in cold weather

Many people think that when the car doors are closed, the temperature inside 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 air conditioning work in a car?

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 the heating mode is on, is the A/C button turned on?

In fact, many car users still mistakenly believe 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 stop car windows from fogging up

In cold weather or in humid conditions, the amount of water vapor in the car often condenses on the glass, causing the glass to fog up. To clear the fogging 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 set the temperature too much warmer than outside. According to health experts, it is enough to keep the people in the car from feeling 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 getting out of the car.
