No MBs have electrically heated windscreens AFAIK.
Early R230 up to 2004 had the option for a heated front windscreen but only in the wiper parked area.
One could also get a fully heated windscreen on the W211 or W220 but only with SA code 979 "Special Protection Vehicle"
On the 211 both the windscreen and front side windows are heated. The 220 only got the front screen. Power consumption is 42A for the screen and 10.5A each the side windows. The windows are heated when the defrost button is pressed and the engine running. Time on is dependent on engine speed, from 6min at standstill to 11min at 100kph.
I can't find any info regarding current models though
