Hello everyone,
we are planning a prefabricated house using timber frame construction. It will have 180 sqm (1,937 sq ft) of living space with underfloor heating, and about 230 sqm (2,475 sq ft) of usable area.
So far, the offer included an air-to-water heat pump from Daikin (Altherma 3R, formerly Rotex HPSU compact Ultra).
Now it seems that this unit might not have enough capacity (?) and as an alternative (additional cost around 4,000) we have been offered a "Wolf heat pump CHC Monoblock 10/300-35".
The Daikin is available in the 4-9 kW version—would that really be insufficient for this size? And what do you think about this offer?
I have the energy-saving regulation heat protection certification and a renewable energy heat law document available, if any information from those is needed.
Thank you very much!
Best regards

15 cm (6 inches) would have been nonsense anyway. 10 cm (4 inches) is enough.
But why is there an empty area at the bottom left?No, I already have that kind of overlap. I had the heating load calculation done for it.That area is empty because they only just started today.

Just under no circumstances increase the supply temperature for the entire house because of the 10 square meters (108 square feet) bathroom (or in the end even reduce the pipe spacing).
The pump has nothing to do with the supply temperature either.

Hey, I had a complete detailed heating load calculation and installation planning done. I am fully aware of everything.
This has already been discussed throughout this thread. My question is about how much you can throttle the modified heating circuits and how this affects the pump head or the flow rate under pressure.
The smaller 55mm (2.2 inches) Arotherm, for example, would not have been able to provide the required flow rate for our house.
