Ik ben niet alleen lekker met kaas!
Moar nerdy numbers, especially for @gaasc since I did a similar test with my eGolf ages ago : heater efficiency/consumption when starting from very cold.
Since my car has this weird screen that shows consumption and what's using it (and because I had forgotten to turn on the scheduling that defrosts the car automagically at the time of my choosing), I was sat in a completely frozen car (temps just dipped into the negatives yesterday), looking at some numbers on my dash. All in all quite interesting :
After a couple of kms of stop/go traffic with everything on (heater/heatpump, heated seats, heated steering wheel, window defrost, mirror defrost) the consumption settled around 4 kw. Which actually sounds reasonable. The Golf (sans heatpump) used around 6kw in proper cold weather.
Of course since this meant the combination of using a LOT of electricity but not covering many miles (due to traffic, traffic lights, a railroad crossing) this meant a ridiculous consumption figure :
As you can see my guessometer knows this is bullshit and it only dropped from 390ish kms to 370ish, as it knows/assumes I won't be needing full heating at all times. Had it done that, my range would have dropped to about 140 kms (77 kwh battery / 55 kwh consumption). (FYI I actually gained range back on the way back, since it head heated up to 15ish degrees)
After a while the rear window and mirrors were completely clear so I turned those off
Still 2kw, which is mainly the heatpump I guess? I was curious to see what would happen if I turned off the buttheaters / steering wheel heaters, so I did that next
In conclusion : the heater, once the interior has fully warmed up, hardly uses anything at all. After my commute my consumption turned out to be on the high side but still nowhere near the 55 kwh it originally guessed. Total range dropped from 390 to 367, which is fair IMHO
Bonus : I wanted to plug in at work just to see what I would get, but didn't after seeing how little the next to me was getting :
