… ok, so it was 3.5 degrees when I left, and I switched on 2 heated seats - the climate control is always on front and rear. At present, it is set to 22, so it was going full tilt at the start. From below you can see that, if I turned it ALL off at that point, I could squeeze another 13 miles on range. That said, after 15 minutes and the cabin getting warmer, that had dropped to only 8 miles increase if all turned off. That’s less than 5% of the total range, for a nice toastie car at near freezing temperatures outside.
My car has a heat pump, so I guess that will be much more efficient in its running (I’ve no idea how much by), but even with your 4kw heater, it/you will only be using that to get the cabin up to a warmer temp, then consumption should drop off dramatically.
Heated seats are also of great benefit in the electric world, with less power used to get a warmer feeling direct to body
The battery itself also loses a bit of charging performance in the colder weather.
