Hello!
I'll start.
Heated area 200m2 (2,153 sq ft)
KfW 55 standard
Mechanical ventilation with heat recovery
Current outdoor temperature 6°C (43°F)
Heating energy consumption including hot water 35 kWh
Electricity consumption 9 kWh
COP 3.88

Especially when there is no mechanical ventilation system, this is totally normal. Where do these assumptions even come from?

Well, we shower for a total of about 10 minutes at most, and not even really hot. I already consider condensate on the lower edge of the window excessive. The bathroom is about 13m² (140 sq ft) in size. Maybe the rain shower head is really to blame, as it releases twice as much water as a standard shower head.

Maybe it's really the rain showerhead causing it, which dispenses twice as much water as a regular showerhead.

You simply have the wrong expectations about this topic, that’s it. Better use your energy for something else. 😎

It's certainly not the worst problem, that's true 😉

Why is it that only Alessandro has this problem and no one else? Not everyone has a mechanical ventilation system with heat recovery; most new buildings still don’t have one. Here in our development of 20 houses, we are the only ones with a mechanical ventilation system with heat recovery, while three others only have decentralized exhaust fans.

Others ventilate crosswise or for longer periods, or they don't care.

Sorry, that wasn’t meant as a jab, but I honestly believe that’s the case. More precisely: I think most people actually don’t care. It’s normal for the entire glass to drip after showering… with all the consequences that develop over a few years as a result.

At least you ventilate. Many don’t even do that and then wonder why they have mold.
