Calculate your theoretical energy requirement for a heat pump with the annual performance factor (APF) calculator and have a report or a BAFA application pre-filled.

ATTENTION

In future, the bivalence point will no longer be entered manually by the user, but will be calculated from the entries of the building heating load and the output of the heat pump at standard outside temperature. Since the performance of the heat pumps for the relevant operating points [depending on standard outside and flow temperatures] can only be obtained very imprecisely from the performance curves in the operating instructions, a small tool is available here with which you can quickly and easily determine the performance of the heat pump at standard outside temperature.
