NL thermal efficiency coefficient according to DIN 4708. The NL index, referred to the integration exchanger, indicates a num-
ber of apartments having 3.5 people that can be fully supplied, with a 140 l bathtub and two other drawing points.

Vbu (*) The non-solar usable volume indicates the quantity of water (in litres) heated directly by the thermal integration coil. It
is calculated as the volume between the upper part of the heater and the lower part of the thermal integration element
(integration coil lower turn).
Vsol (**) The usable solar volume indicates the quantity of water (in litres) heated directly by the solar coil (placed in the lower
part of the heater) minus the non-solar volume (Vbu).
