Hello everyone,
we have been living in our newly built house (Efficiency House 55) since June 2021.
A hydraulic balancing was performed and adjusted accordingly by the plumbing company at the beginning of last week.
In the past few days, I have read up a bit on the topic and I think I have a reasonable understanding of the heat pump and underfloor heating system principle.
This morning I exported the data and hope you can give me helpful tips on how to reduce the heating a bit.
I also have the hydraulic balancing plan if that is important.
Thank you very much.

Set your forward temperature to 32°C (90°F) instead of 45°C (113°F) initially, as 45°C is too high for a heat pump. It should get cooler this way. Monitor the system for a few days to see if this setting is appropriate. If it gets too cold, increase the temperature slightly, but only in 1-2°C (2-4°F) increments, and always wait 2-3 days for the system to stabilize before making further adjustments.
