These data characterize the size and performance capability of the system. For economic and energetic reasons, additional
factors such as balance point and control need to be taken into consideration. Abbreviations have the following meaning, e.g. B10 /
W55: heat source temperature 10 °C and heating water supply temperature 55 °C.
