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

Pixelsurium6 Aug 2020 22:27Hi everyone,
so far, I haven’t seen or received any calculations…
Which data from the thermal insulation certificate according to the Energy Saving Ordinance would be important? (It’s 16 pages)
I’ve attached the Renewable Energy Heat Act and the results pages from the thermal insulation certificate according to the Energy Saving Ordinance behind it (see PDF here).
Does that help?
Best regards
