The measurements are performed on a limited number of heat pumps
which can cause variations in the results. Tolerances in the measuring
methods can also cause variations.
1) At A7W35 10K warm side.
2) At A7W35 according to EN 14511.
3) Nominal ow: heating circuit 10K.
4) At minimum outdoor temperature 0°C.
5) According to ISO 3741.
6) The values apply to a new heat pump with clean heat exchangers.
