I have discovered that in the cold days if I select HI temperature setting, the inside air will get hot, even when the engine is cold. If I keep the temp setting normal (24~28 C⁰) the car waits for the engine to open the big circuit of water cooling to start the fan for inside ventilation and then the air blown is warm. I want to ask someone who knows, if the car has electric resistive heating, or if it uses the compressor from the AC, in reverse, like modern AC units, to heat up the cabin. I own a 2021 Octavia 4, with 1.0 tsi engine, manual transmission and ambition trim.
