Protocol of hydraulic balancing

Hello,

does anyone know about hydraulic balancing? The background of the question is that my heating engineer drew up the attached protocol without asking. Unfortunately, we have of course laid a completely different floor covering. That means upstairs, in the children's rooms, we laid floating cork and in the hallway and bedroom laminate. Only in the bathroom did we actually lay tiles. Now I have the problem that in winter it is never above 21 degrees upstairs, no matter what I set on the heating. Should the heating engineer have made smaller laying distances, i.e. RA10 everywhere? I know remote diagnoses are always difficult, but I want to know whether there is already a planning error in the hydraulic balancing.

Hello,

...does anyone know about hydraulic balancing? The reason for the question is that my heating installer drew up the attached protocol without asking.

Be glad, that means errors are documented! ;-) The heat generator is probably a heat pump - right?

...Unfortunately, we of course laid a completely different floor covering...

Why? A client must know what they want! Accordingly, the sizing of the heating surfaces and hydraulics is done!
Whether it is correct here, I rather doubt! If I look at the room heat loads, VA, I suspect total nonsense!
Is there a controlled residential ventilation with/without heat recovery?

...Now I have the problem that in winter the upper floor never gets above 21 degrees, no matter what I set on the heating....

Winter? We haven't even had that yet! Retrospective fixes for neglect regarding exact planning/sizing or execution usually lead to more or less significant pains, usually higher consumption costs! ;-)
The causes are manifold: wrong HLB, insufficient consideration of controlled residential ventilation (if available), wrong heating surface sizing, wrong hydraulics, etc.......

...Should the heating installer have made smaller installation spacings, i.e., everywhere RA10?

For what reason? Uniform VA in a building are for me as an expert one of the first indications of a botched system!

...I know remote diagnoses are always difficult, ....

not always. If the planning/sizing is already botched, what else should turn out better?

best regards
