DEAR BUYER,
Depending on their layouts,
buffer tanks can be operated
from several different energy
sources: indirectly from solar en-
ergy, or gas-based, coal-based or
other based energy carriers (i.e.
auxiliary electric heating). Paying
attention to these usage instruc-
tions, you are kindly asked to
turn to a professional technician
to perform the connection of the
appliance in the heating circuit
and to put into operation the ap-
pliance for the first time. Please
read these installation and oper-
ation instructions carefully and
follow the instructions precisely.
In this manner, you can ensure
that your unit will operate in a re-
liable way during a long time.
STRUCTURE AND OPERATION
The buffer tanks are composed of
a steel tank, foamed polystyrene
insulation, PS sheath and a cover.
The tank and the heating pipe coil
are made of St37-2 steel.
As the internal surface of
buffer tanks contain no corro-
sion protection, they can only
be filled up with heating wa-
ter. They are not adequate for
storing drinking water!
The insulation of the tanks is pol-
ystyrene (with graphite) foam of
thickness of max. 110 mm; and their
sheath is made of plastic. Both the
sheath and the insulation are mount-
able (over 500 liter capacity), so the
tank can be fixed into its operation po-
sition through their removal (as well).
Without its insulation, the largest tank
can be carried through the door of size
800 mm. Combined buffer tanks
(PT_CF) provide sanitary hot water in
an instantaneous way, heating cold
water through the wall of the flexible
pipe of stainless steel. The foamed
polystyrene surrounding the internal
tank keeps the water at given temper-
ature for a long time, without any en-
ergy intake.
Type selection:
Buffer tanks are sold in standing
forms, with volumes of 500, 750 and
1000 litres, “combined”
(PT_CF)
lay-
outs. combined tanks (PT…CF types)
contain a flexible pipe of stainless
steel to produce sanitary hot water.
The most important external and con-
nection sizes of the appliances are de-
scribed in Table 1 and in Figures 1 be-
low.
Operation target
Buffer tanks work as energy storages
for heating systems. They balance
timely discrepancies between heat
production (or available energy) and
heat need, thus ensuring conven-
iences.
