No worries. If you get utterly stuck, like I say I can try and sort one out for you, but I just don't want to promise you one if I'm literally unable to get to scrappy/spares car - all that time you're left hanging on my word.
Certainly I'd just get whatever bonnet mounted nozzle(s) you can find, as a 'get you back on the road' kind of thing - and look at one with a heater element later - or indeed, get a couple of nozzles, and hack your old one to bits and install in a spare new one.
To be honest the heater element is perhaps a little bit of a gimmick, most cars don't have them, and if it's so cold as to have iced up the window your screenwash won't do much, you'll be outside with de-icer anyway. (or sitting in the drivers seat with the engine and blowers on, waiting for the screen vents to melt the ice, again, still no need to use the screenwash)
