Underfloor heating air-water heat pump. House too warm when the sun shines

That's how it is. I just see that in the bedroom dressing room one heating circuit has no flow and the other has maximum flow. Even twice as much as the heating circuit in the bathroom. You should never throttle heating circuits in the hallway either, because then the hallway has to be heated by the other rooms like the bathroom, which takes heating capacity away from the other rooms, unnecessarily forcing you to raise the heating curve, wasting efficiency. This can neither be called a proper hydraulic nor optimized thermal balancing.

Could you please list in a table per floor Room - sqm - number of heating circuits - current flow Please also include rooms without heating circuits if there are any. It makes it easier for me to get an overview. Infrared thermometer available? Thanks in advance

Then I understand the house now

The exact model designation of the heat pump would still be important in order to look up the nominal volume flow rate.

Hey, well, we have the Novelan Lad9. I can't find a more precise designation. I just ordered a thermometer as you recommended.

I'll make the table: room - sqm - volumetric flow for you tomorrow or later, if I manage to finish it.

Regarding the current settings of the flow rate, is it worth optimizing or is all hope lost?
