Power per square millimetre of coil surface (mW/mm²). The WINDBAR coil wrapping calculator paints a typical 120–350 mW/mm² band. Not a flavor guarantee.
Rebuildable users watch heat flux when a wrap feels harsh or slow. If the band reads hot, lower wattage or change wire mass before you assume the liquid is the problem.
At 25 W on a coil with 80 mm² surface, heat flux is about 310 mW/mm² — inside many builders’ balanced band.
