Although the inductance is probably not enough to worry about, the cold
resistance of the element will be less than the resistance at operating
temperature. This means that the initial current at switch-on will be
higher than the normal operating current.

Yup, I was aware of that and measured the current draw under warmed-up
running conditions.

what you need to know is cold resistance.
