3. Connecting the serpentines (heat exchangers) with the heating
installation using alternative and renewable sources
ATTENTION! Qualified P&P spe-
cialists and technicians must per-
form all the assembly works for
connection to heat sources.
The connection of the serpentines (heat
exchangers) with the heating installation
should be done considering the marked out-
lets and inlets as described below:
IS1 (MS) – Inlet of the heat exchanger 1
OS1 (ES) – Outlet of the heat exchanger 1
4. Connecting buffers to the central heating loop
buffers for the central heating system are
intended for heat accumulation and strati-
fication with the subsequent distribution of
heat flows with different temperatures to the
specific consumers. As an example, Fig. 12
shows the high and low temperature heating
realized by the buffer. Heat demand is cov-
ered by a gas boiler and high-temperature
boilers on upper layers and solar collectors
in lower layers.

IS2 (M) – Inlet of the heat exchanger 2
OS2 (E) - Outlet of the heat exchanger 2
When filling the system with transfer fluid,
the system should be empty of air. Make
sure the system is empty of air. The pres-
ence of air may cause the incorrect function-
ing of the boiler.
The temperature of the heat exchanger
must not be above 110°C.
ATTENTION! The buffer is part of a
complete heating system that must
be designed and checked by spe-
cialized and authorized personnel!
The installation of a safety valve
with an exact release rate is obliga-
tory! The maximum designed pres-
sure of the buffer is 3 Bars!
