About the resistance wire power calculation:
Voltage × voltage ÷ (line length × resistance) = total power
For example: 12V with 12V, select 0.6 ohm heating wire
12V × 12V ÷ (0.6 ohm / m × 5 meters) = 48 watts 5 meters = 48 watts maximum temperature within 60-80 degrees
For example: 220V for 10 meters, select 74 ohm heating wire
220V × 220V ÷ (74 ohm / m × 10 m) = 65W
For example: 220V for 8 meters, select 74 ohm heating wire
220V × 220V ÷ (74 ohm / m × 8 m) = 91W
This heating line can heat the air, heat the water and other places where the heating temperature is not high, the line and the line can not cross, the line is not less than 2 meters and 220V (different resistance, the length is not the same), just press the above formula Calculating a power of less than 20W per meter is a safe range!
