Unfortunately, I have no information about that; see below for KfW55Are they actually laying "straws" there? What diameter and wall thickness do the heating coils have? KfW55 and 38 degrees somehow don't quite match.
Sounds reasonable. The outdoor temperature is assumed by the planner to be -16 degrees, and the bottleneck is currently not even the bathroom, for whatever reason.I would design the bathroom for 23 degrees (down to -10 degrees).
According to telephone information, it should be 45W/m². It should be noted that KfW55 is not owed, only communicated later because the subsidy was applied for. However, the energy consultant messed that up/submitted it too late (same engineering office). It is quite possible that it was redesigned back to the minimum standard according to the Building Energy Act.What is the total heating load of the building? For KfW55 it should not exceed 35W/m².
I would have commissioned that myself if I had had enough information. I no longer trust the MEP planner. But he was commissioned by the developer, and I have to try to get the best out of it. The lady does not want to provide me with a room-by-room heating load calculation, but the developer promised me that I can get the documents. I have now requested it through him in the hope that this will bring some more clarity.All renowned heating manufacturers now do a heating load and installation calculation.
