BAFA funding for air-water heat pumps in new construction - how does it work?

I played around with the annual performance factor calculator on the Rotex HP website. I can’t get it to 4.5 no matter how I turn it. So it’s settled anyway. Many thanks

We also only got up to a maximum of 4.1 with our Tecalor according to the calculator... Is it even listed among the heat pumps eligible for funding?

yes, she is listed in the list

Hello,

we have received 4500 € for our geothermal heat pump!

According to the standard, we would have had an air-water heat pump and upgraded to a brine-water heat pump; including the subsidy, is it worth it (the surcharge) ... not without it

In that case, the date on which you place the order for the heating system would also count, or even the date on which the heating system is commissioned by the heating engineer.

Is simply too late,
