KfW 55 + BAFA Funding - Costs and Subsidies

You are welcome to check with the annual performance factor calculator; all HPs that are on the list should also achieve the eligible annual performance factor.

Yep, and a large portion of all pumps in the wild don’t actually have this annual performance factor because they are poorly adjusted.

However, this is not relevant for the Bafa because:
What happens if the calculated annual performance factor in the funding application deviates from the measured annual performance factor?
For subsidized heat pump systems in new buildings, a quality check of the system must be carried out after one year of operation. In this process, the calculated annual performance factor in the funding application must be compared with the actually achieved annual performance factor in real operation.

However, besides the quality of the system, user behavior also plays a significant role in the actual annual performance factor. This can only be considered to a limited extent during the determination of the calculated annual performance factor. Deviations are therefore quite normal. The granted subsidy will not be reclaimed afterwards.

Fine, I hadn’t considered that. Even better! Nevertheless, it is of course desirable to achieve or even exceed this value.

Yes, this is the new Monoblock from Wolf, if you take it together with a [Kontrollierte-Wohnraumlüftung] from them, the [Kontrollierte-Wohnraumlüftung] can even be subsidized because there is a joint control system. This also works with heat pumps from other manufacturers.

Of course, you want to achieve the value yourself in order to save

The annual performance factor already helps with that, the supply temperature of the underfloor heating must then really be as specified there.
