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) Distribution losses outside the DHW cylinder are not taken into account.
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.
5) In the case of heat generators with a higher heating capacity, limit to the stated value.
