Whilst not being able to answer the question outright, the heated front screen Ford harness is in 30 amp wire and the switch includes a timer for ~7 min operation so obviously Mr Ford decided that the current draw was too much for continuous use. My screen melts a 2-3 mm covering of ice outside and ~ 1 mm covering inside within 30 secs (which is really useful) but leaves the screen covered in water and the central area untouched hence the earlier comments.. I do not have either an amp-eater (difficult with an alternator other than very old moving iron type) or any voltage indication fitted so cannot comment further.

I did wonder if an MX 5 glass rear screen (or similar) could be made to zip into a replacement hood for the 2+2? I understand you need air blowers for de-misting on a car with a full screen for SVA/MOT. Does the heated element front screen overcome that requirement? I wonder what the Amp draw in those are? I find that on the frosty days you still need to warm the screen to stop it misting up, even with the top down. Though I do drive hood down on any good day through the year. My favourite times are hot summer evenings after the sun has gone down and the cold winter days in the sun. Can't beat it.
