These data characterize the size and performance of the system. For economic and energetic
considerations, additional factors such as defrosting behaviour, bivalence point and control need to be taken
into account. Abbreviations have the following meaning: e.g. A7 / W35: outside temperature 7 °C and
heating water supply temperature 35 °C.
