Before you consider a heated front screen, note that with some angles of the Sun the thin wires show up inside the windscreen, and can be rather off-putting, as your eyes zero in on them.
I had that on one car (not Ford) and did not like it. Never had it since.
The Ecosport using A/C , firing with vents to windscreen, with recirc on, does the same job and quite quickly.
I use it in winter a lot. Anyway you must use your A/C every week, winter and summer, as if you don't, the seals dry out and gas is lost, then you end up with a re-gassing bill quicker than you thought.
