1) Without solar heating or reheating; selected cylinder temperature 60 °C
2) Mixed water at the draw-off point (at 10 °C cold water temperature)
3) Distribution losses outside the buffer cylinder are not taken into account.
4) The performance factor N L=1 to DIN 4708 for 3.5 occupants, standard bath tub and kitchen sink. Temperatures: cylinder 60 °C, outlet 45 °C and cold water 10 °C. Measured
at max. heat input. The N drops with reduced heat input.
L
5) Limit to the stated value for heat sources with higher heat input.
