1. This data indicates the size and capacity of the system according to EN 255 or EN 14511. For an analysis of the economic and energy efficiency of the system. the bivalence point
and regulation should be taken into consideration. The specified values, e.g. B10 / W55, have the following meaning: Heat source temperature 10 °C and heating water flow
temperature 55 °C.
