BAFA innovation funding air heat pump

Since you can't achieve the 4.5 with an air-source heat pump, the probability is 0%. Inform yourself or not.

Quick question - how does the proof of the annual performance factor actually work? I applied for a wine air-to-water heat pump and received the confirmation; but we live on the alp, so probably the same temperature range

You do not need to provide proof whether it really reached the 4.5.

A calculation verification according to VDI must always be provided. The values actually achieved in practice largely depend on user behavior and are therefore irrelevant for the funding.

And how did you manipulate it? I have the most expensive inverter Novelan heat pump and achieve about 4.2 calculated. Where is the error?

The funding requires that an annual performance factor of at least 4.5 must be achieved. Until March, this could still be calculated with the old version of the VDI. From March onwards, however, it must be calculated according to the new VDI. The new calculation method is closer to practical conditions. Therefore, generally worse APFs result from it.

P.P.S Under no circumstances install a heating buffer with a heat pump.
