Assessing the water quality
special stainless steel evaporators
(heat exchangers) are integrated
into the water | water heat pumps
with designation wPw from
stiebel eltron; the connection
between the individual plates are
also made from stainless steel. this
ensures a particularly high level of
corrosion resistance against almost
all constituents found in groundwater.
Consequently, the permissible
application range of these heat pumps
regarding the prevailing water quality
is very wide. the use, however, is
limited as follows:
only groundwater, i.e. no surface
water or saline groundwater
no constituents that might settle
iron and manganese ttl. < 0.5 mg/l
in pertinent individual cases, e.g. wells
near salt mining areas or regions with
a great prevalence of livestock, the
following water constituents need to
be taken into consideration:
Chloride (Cl
-
) < 300 mg/l
Chlorine (Cl) < 0.5 mg/l
