Good day.
We have noticed that our neighbor in the multi-family house (6 units, KfW 70 standard, built in 2016) has extremely high heating costs.
We have underfloor heating throughout (standard windows with mechanical ventilation), pellet heating.
We suspect that his heating habits may not be quite correct.
Can anyone say what might possibly be done wrong?
90 m² (970 ft²), upper floor, single household (retiree). Consumption in October was about 400 kWh for 90 m² (2 weeks quite warm, 15–10°C (59–50°F) in October, 2 weeks around 10–0°C (50–32°F) in Bavaria).
Rooms such as the living room, bathroom, hallway, and bedroom are heated to about 21°C (70°F) using room thermostats.
The office is not heated at all.
In general, he likes it warmer.
However, he does not heat the office at all.
Ventilation is done normally through the window (occasionally tilted).
Who can advise on how to properly heat with underfloor heating for a single person (retiree)?
Thank you very much.

I find 18-20 degrees quite low.
Here, in the evenings now (October 24 degrees Celsius (75°F)), I have increased the heating curve so that the heating actually turns on at an outside temperature of 10-15 degrees Celsius (50-59°F).
If you find 18 degrees Celsius (64°F) sufficient, the heating doesn’t have to work hard during the day. This might also explain the difference compared to the other apartment, especially if an additional room needs to be heated.
Warmth is very subjective. For some, it is the most important aspect of living space 24/7 and they prefer to air out cold air. Others prefer to save on heating costs and rather sit in the living room wearing a cardigan, to save a bit of money by the end of the month.

I raised the heating curve so that the heating system will turn on at outside temperatures between 10-15°C (50-59°F). A typical issue during the transition period.
To address this, the heating curve is adjusted vertically. Depending on the system, this can be controlled in different ways.
However, the heating curve itself is not changed. It is readjusted again when the weather gets colder.
