Hi everyone!
I'm coming across topics in which I have built very little knowledge so far but now have to deal with.
Basically: we have an air-to-water heat pump (Tecalor THZ 504) and underfloor heating.
Our heating installer performed a "hydraulic balancing" before handing over the house, there are documents about it and it was apparently relevant for the KFW.
Therefore, the sanitary advisor once told us that we should actually not / may not change anything on the heating system ourselves (?), because that was the basis for the KFW subsidy.
Now we do live in this house, however, and in practice we have a few minor issues with the heating.
Overall, during the cold months, the temperature in the house was pleasant. Since spring is coming, it's slightly too warm for me inside. As far as I know, you have to adjust the "curve" a bit here. Simply lowering the temperature would probably not make sense because the heat pump controls the room temperature based on the outdoor temperature, and since it was okay in winter, I assume something in that relation is not right. If I lower the temperature myself now, then I would have to turn it up again when it gets colder, which somehow doesn’t seem sensible to me.
Furthermore, the bathroom upstairs is constantly too cold (significantly), and the bedroom is too warm (a bit).
This is related to the fact that we always turn the room thermostats fully on according to agreement with the heating installer (anything else would be a waste of energy, we were also told here in the forum), plus the things would keep clicking otherwise, which is annoying (especially at night). In the bathroom, even fully turned up, simply not enough heat arrives for my feeling. In the bedroom, it quickly gets too warm, we prefer to sleep rather cool anyway.
Is there a way to adjust this so that the bathroom gets warmer and the bedroom no longer gets so warm, without turning down the thermostats? Like changing the distribution?
And are we allowed to do that even though the hydraulic balancing was carried out? (I don't really know what that means).
I also found in the documentation I received recently a planning note from the executing company for the underfloor heating stating "reduced output" for the bathroom of 49W, requiring additional heating surfaces. :/ However, we do not have those. During the selection process, we sorted out the towel radiator, with the reasoning that it wouldn't get really warm anyway with often below 30°C supply temperature.
What we didn’t consider and know at the time was that it probably would have helped us to heat the bathroom overall higher.
