Eligible costs for heat pump

A quick question: I am buying a WOLF CHA from installer A and a controlled residential ventilation system from Zehnder from installer B. But then I have two invoices from different companies, can I upload both invoices to the BAFA, or does there have to be a single invoice that lists both devices?

Thank you

You can upload both in the upload area, but does the controlled residential ventilation (individually) count towards it? Why should there be funding for that?

Of course, funding is only provided in combination. The question is whether I can upload two invoices because the devices are installed by different installers but operated together.

As long as you can provide proof of joint control for both, two invoices should also be acceptable. The decisive factor is the joint control.

I believe the upload area has the option to upload various documents, that should not be a problem. Someone posted a screenshot of it somewhere here in the forum.

Hi,

Again on the point of the inspection after 1 year:

I have read up a bit on the required annual performance factor > 4.5.
It is fundamentally said that this is an ambitious target for air-to-water heat pumps.
Furthermore, the annual performance factor cannot simply be determined by device specifications. It also depends on the location of the heating system. Among other things, the required annual performance factor is more easily achieved in areas with mild winters than in areas with very harsh winters.

I am not a heating professional... can Bafa determine the actual annual performance factor after one year?
If so, they would probably legally be entitled to reclaim the subsidy if the annual performance factor is not met.

Edit:
Even after another look at the Bafa information sheet, the question is answered:
Bafa assumes deviations in practice and therefore sets the value that high as a hurdle. There is no reclaim.
