What is the most suitable temperature for car heating?

[ErinLee]

The most comfortable temperature for humans is between 20℃ and 25℃. Here are the relevant details: 1. Temperatures above 28℃ will make people feel hot, while temperatures below 14℃ will make people feel 'cold.' Therefore, it is best to control the temperature inside the car between 18℃ and 25℃. Generally, the temperature difference between the inside and outside of the car should be within 10℃. 2. When driving in the morning during winter, do not turn on the heating immediately after starting the car, as the engine is still cold and will not produce warm air. Instead, warm up the car first and wait until the engine reaches a certain temperature or the water temperature rises before turning on the heating. 3. Another important point is not to press the A/C button when using the heating in winter, as this controls the car's air conditioning compressor. The heating system utilizes the residual heat from the engine's cooling system to function and does not require the compressor to produce warm air. Pressing the A/C button while using the heating will only increase fuel consumption.
