4-5-A-C-E: 2 heating zones and sanitary hot water + cascade via low loss header
Description
2
x R40 with low loss header
Cascade c weather
compen
sation
2 mixed heating zones
Sanitary hot water
Tips
Low loss duo headers are available
for
∆
T=15-20K (see chapter
"
Accessories
"
).
The primary circuit should be
de
signed for
∆
T=20K, this guarantees
a
high boiler efficiency.
When the sec
o
ndary circuit is
de
signed for a
∆
T smaller than 20K,
the
flow temperature in the header will
be
lower than the flow temperature of
the
boiler. This should be taken in
to
consid
eration during the design stage.
The header should be positioned
close to the boiler, to avoid a negative
influ
e
nce on the temperature control
quality.
In case of a boiler room installed on
the roof, the boiler may never be
hy
draulically connected at the highest
point of the installation.
