they defiantly freeze up, i had undiluted concentrated screen wash in and it still froze at the nozzles and on the windscreen wipers and windscreen, although once i put the blowers on just the windscreen it no longer froze on the windscreen but still froze at the nozzles and wouldn't spray
it was minus 9c (cold for england but warmer than some places)

How old is your washer antifreeze? And what is it rated at?
The better brands in North America are rated down to -35*C.
If the antifreeze is old, the alcohol may have evaporated off. That is also the problem with heated nozzles as the heat would evaporate the alcohol while sitting in the jet and nearby hose.

I bought it that day.
I have just checked and it is only rated to minus 5 deg c, it says to mix 25% to water summer
and 50% to water in winter
or use undiluted in severe conditions.
The minus -5c must be undiluted.
I got it from asda/wallmart
I'll read the label more carefully in future. Doh !!! and look for some with a lower freezing point.

-5*C for "severe weather"?
That's a cruel joke on their part. What if someone didn't know, and pumped some on the windshield while at speed on a motorway?
At least now you know where the problem lies.
BTW, if at all possible, wait until a clear stretch and get your bearings before cleaning the windshield. That way if it freezes over or smears, you have an easier time maintaining your path of travel while you do whatever is necessary to clear the windshield.

Comma :: Products Guide :: Screenwash
Widely available from Motor Factors, surprisingly Halfords currently sell it at £3.99 per litre.
It's spec is down to -65 deg C when used at 100%.

I would have to question the functionality of heated washer nozzels. How would this keep the fluid in the rest of the system from freezing?
Living here in the frozen north, almost all our fluid is rated for -30*C or lower and is sold by every corner store in 4L jugs. Cheap too.

While heated nozzles might be fine at just below freezing, they would actually work against you at colder temperatures. Elevating the temperature above ambient "boils" the alcohol out of the mix which raises the freezing point. Then it hits a windshield that is at a colder ambient than the raised freezing point leading to instant ice formation. What you actually want is a liquid that stays liquid at ambient. And that is better quality antifreeze.
In your situation, if you get some of the antifreeze recommended by GGG and siphon off half of what you already have, you can replace that half with the better antifreeze and end up with about -30*C antifreeze. You can either dump the old stuff or mix it into the remaining good stuff for a second jug of -30*C antifreeze.

The only heated systems I'm familiar with here in the colonies had the intent of squirting a single shot of warm fluid on a cold windscreen to help melt an accumulated film of frost or ice. The drawback was needing to wait 5 minutes or so after engine start for the fluid to heat. There was no intent to keep the 4L of fluid from freezing in the reservoir, the lines or the pump. Given the location of the reservoir, I can't imagine engine heat doing much.
Does your windscreen have the fine wires visible in the glass? If no, you don't have the heated version. By your description of peering through a small clear patch, I'm guessing not.
