kwh/a = kilowatt hours per year

No, no, the pages are useless. That is the calculation of the annual energy demand.

That is the energy (kWh/a), but we need the power (kW)

I’m not familiar with that thing.

Decisive points were mentioned. Heat load calculation, room-by-room heat demand calculation. If possible, specify flow temperatures for the underfloor heating. What is the contractual situation? GU contract, individual trades, everything already signed? If yes, what was contractually agreed?

The air-water heat pump was included in the house contract; I was now told that we have the choice between the Daikin 8 kW (however, this one would not be eligible for funding) and the air-water heat pump from Wolf with an additional cost of about 4000.

We will probably only get the heat load calculation after choosing the air-water heat pump (lol?)

Which manufacturer do you generally tend to prefer, Daikin or Wolf?

Best regards

If the Daikin 8 kW is enough, then the Wolf 07 is also enough. I would not take a heat pump without funding. The Daikin should also be eligible for funding, you have to check the Bafa list.
