1) Without solar thermal heating or recharging; set cylinder temperature 60 °C.
2) Mixed water at draw-off point (at 10 °C cold water temperature).
3) Excluding distribution losses outside the cylinder.
4) The rating code N
L
=1 according to DIN 4708 for 3.5 persons, standard bath tub
and kitchen sink. Temperatures: cylinder 60 °C, DHW outlet temperature 45 °C
and cold water 10 °C. Measured at max. heat output. If the heat output is
reduced, N
L
becomes smaller.
