How should the ambient temperature be determined for electric heat tracing calculations?

When performing calculations for electric heat tracing, how should the ambient temperature be determined? Should the heating temperature be calculated based on outdoor conditions? Average temperature of the coldest month? Or based on the extreme minimum temperature?
When performing calculations for electric heat tracing, the value of the ambient temperature should generally be based on the worst-case scenario, that is, the extreme minimum temperature. This ensures that the electric heating system can still function effectively under the harshest environmental conditions, preventing pipe freezing or other problems caused by low temperatures. .
Choose the coldest temperature; in Shanghai, I chose -10 degrees
