From cooling the engine.

Yes, keep going. Now where do you think the heat in the engine comes from?

The heat doesn't use anymore than the AC because it's the same system running in reverse.

Using heated seats offsets the need to heat the air.

With 150kWh/100km consumption

WTF is this, a dump truck? It's ~240wh/mi x 62 miles = <15kWh/100km

The answers to your question is already in my post and the 150 was obviously a typo, because the loss in range checks out. It should be 15. AC uses less because the temperature difference is less.
