Drivel. As usual you are "expert" on something you have zero
knowledge and experience of.

Its simple arithmetic harry. 13A @ 240V for 8H is ~25kWh - about the
same energy content as that contained in 5L of petrol.

As the efficiency of electric cars is around six times that of ICE,.....= six liters of petrol.
Plus regeneration = yet more.

And the efficiency when you stick the heater on in winter?

As you should know electric heaters are 100% efficient.
It depends on whether it has a heat pump or a resistance heater.
I just put a fan heater in the car for 15 minutes before I set off.
Also it has heated seats which are all that's necessary in Winter.

Is that needed? I thought you could turn on the car heating using a
mobile phone app while the vehicle is still plugged into the 'shore'
supply.


You can (or might be able to) with some cars.

I thought my sister-in-law said the Nissan Leaf worked in this way.

And ten minutes down the road? U values of cars are not good.

True, but the same would apply to using a fan heater. as suggested.



The air con in my van is very nice.

It costs less to use it on a MPG basis than opening the windows of the van.

Try that with an electric Leaf:-)
