When snow is forecast in USA (and Canada), they close the roads. The "plows" go out in force and the snow is shoved on the side walks. But their weather is more predictable so it's worth having the permanent systems needed to keep the roads clear.

UK has such unpredictable weather we never know when or if it's going to snow.

Re: where does the heat come from in electric cars?

Electric car charging will be a serious problem if we allow the likes of Ionity to take the micky on costs. They recently went to a subscription system that charges non members about £0.60 a unit.

Quote
Frequent drivers in the transit tariff (17.95 euros per month) receive a preferential price of 0.31 euros per kWh at ionity columns. Customers in the city tariff (4.95 Euro per month) must continue to pay the full price of 0.79 Euro per kWh at Ionity.

They have installation costs and electricity costs but considering domestic power will cost about 12p per kWh that's a serious margin they are expecting people to pay.

On the other hand free to use chargers are silly in the other direction. The equipment and power lines have to be installed and maintained.

Re: where does the heat come from in electric cars?

Later cars had the Eberspacher diesel powered heater but reliability was not a feature they were renowned for. My top spec (six captain seat) Mk1 Sharan 1.9 had no block heater.

If they had modern battery tech back then I could have seen it selling well assuming a reasonable price

Its so old Dave.. that the battery and motor probably gave off plenty of heat

Pricing was probably DOUBLE what a new 903 would cost you

Nothing has changed in that respect..

Ford are credited with creating the heated screen, and initially they were very expensive as only 1 in 3 from production were fit to use.

Now most Ford cars have them as standard, but typical Ford, they are made poorly. They work well, very well, the ice and snow just melts off before you've scraped the front side windows. I had heated screens with the AA Driving School Fiestas for 8 years, but despite the benefit on cold mornings, would prefer not to have them.

On all the heated screens I have seen, not just Ford, the heating wires are visible. Very visible on Fords, often difficult to see, but still there on others. All the time with the Fords, you are squinting through these lines, makes a nonsense of keeping a clean windscreen when they have obstructions built in. When the sun drops in the sky, they become worse.

Then in the dark, every oncoming car will highlight the wires, glinting at you, reducing the visibility. Far worse in the Fords than in other makes.

I was glad to say goodbye. No heated screen in the Fabia, and does not take long to put warm air up for demist.

Re: where does the heat come from in electric cars?

My sons Focus tdci had it..
It was like having 'chicken wire' instead of glass

Although probably useful in a diesel.. as you can do half of a winters journey before any meaningful heat arrives through the vents

Re: where does the heat come from in electric cars?

A friend had a Ford Escort Convvertible XR3i - or at least thats what I think it was. It too had a heated windscreen and as has been pointed out they were very expensive.

One morning he went out to his car and found some scumbag had stolen the windscreen!
However they failed to notice the expensive leather jacket on the back seat with a well-stuffed wallet in one of the pockets

Until someone pointed out the wires in the windscreen, I never noticed them, but after that I couldnt stop myself trying to focus on them rather than the road ahead!

Aircraft have heated windscreens that get really hot - but there are no wires - instead the screen has a thin, transparent, conductive film over the surface to which a voltage is applied which evenly distributes heat over the entire panel. The window film is usually a Indium tin oxide, or gold - far better than a windscreen full of wiggly wires!

This design probably isn't used on everyday cars due to cost.

The aircraft ones probably just massive amounts of power as well as the fact there has been a lot of issue's caused by them on aircraft over the years
I'm betting something like 2-4kw those system run at will take a lot of heat flying at 500mph and 38k feet

I doubt they run at car voltages either probably 100v+

That and most cars probably don’t really have to worry about the massively low temperatures that planes experience at 40,000 feet.

I’m sure the aircraft set up is much better than the wiggle wires of your average Ford Focus lol

He had a 307 before the focus..
Much better spec. Car
The Hdi could have a diesel fuelled heater from the factory
