Do you need to wait for the water temperature to turn on the air conditioner for heating in winter?

In winter, the car needs to wait until the water temperature rises to normal temperature when the air conditioner is turned on for heating. In winter, the temperature of the water tank is low, and the warm air is turned on as soon as the engine is started, which will inevitably increase the burden on the engine and delay the rise of water temperature. And even if the warm wind is turned on, the cold wind will blow out, and the body feels uncomfortable.

The correct way is to use warm air when the water temperature pointer reaches the middle position or the blue indicator light goes out. It is suggested to turn on the external circulation to discharge the cold air in the car first, and then turn to the internal circulation after a few minutes to let the warm air blow in.

Extended data:

Car heaters and air conditioners use completely different working principles. Car warm air mainly comes from the heat of the water tank. It uses the circulating water of the engine to generate heat, and then the hot air is blown out by the blower, which does not consume oil at all. Even if the warm air is not turned on during driving, the heat will be discharged from the car and wasted. So you can turn on the warm air in winter, regardless of fuel consumption.

When turning on the warm air, do not press the AC button, because this button is the compressor start button. The correct way is to blow out warm air just by adjusting the air volume and temperature.
