Brief description
The Stiebel Eltron DHC instantaneous
water heater is a hydraulically-controlled
pressure unit for heating cold water, with
which one or more water taps can be
supplied; see Table 2.
Installation location
The unit is suitable for the
preparation of hot water (potable
water supply), and is to be installed as
far as possible in unvented areas free of
the risk of freezing, as close as possible
to the water tap (dismantled units are to
be stored so as to be free of any risk of
freezing, since there will always be
residual water left in the unit).
The DHC unit is to be installed
vertically, in accordance with Fig. 4.
Under-sink: DHC 3 U and DHC 6 U
Over-sink: DHC 3, DHC 4, DHC 6
and DHC 8.
