    Jj I'm hesitant to make a recommendation, as 300 to nearly 400w for a door heater is so far off from what we're using.

    Does that Kolpak unit have metal strips that cover the heater, that perhaps...

    Jj I don't know the door dimensions, but common ones have about 18ft circumference.

    If so, your installed 2.5A heater would be pushing near 17w/ft @120vac, no?
