Tips
Complete accessory kits with plate
heat exchanger are available for
∆
T=10-20K (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 of the plate heat
exchanger will be lower than the flow
temperature of the boiler. This should
be taken in
to
consideration during the
design stage.
The plate heat exchanger should be
positioned close to the boiler, to avoid
a negative influ
e
nce on the
tempera
ture 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.
