Power usage difference between using heater and fan ventilation.

Hi this is my first post regarding my 24 plate MG4 Trophy ER An absolutely fantastic vehicle .
I have an observation to make which is the mileage appears to drop the same amount whether I have the heater on or just the fan ventilation. Is this correct ? It just seems a bit odd .
Thank you

The GOM (guess-o-meter) just estimates a set drop in range when something is on vs off, it’s not particularly accurate but that’s just how it is I’m afraid.

Same with setting the car to eco or sport, it makes an assumptive guess as to the effect on remaining range.

It's just a nominal adjustment, seems to be a reduction of about 5% of the remaining range when you press that button, regardless of temperature or fan setting.
