Boiler pump (1).
The boiler pump operates on the primary circuit return, im-
mediately downstream of the 3-way valve which is connected
to. It is part of the integrated multi-function group made out
of composite material.
The automatic vent valve (2) is also housed in the hydraulic
group casing.
Primary heat exchanger (1).
The primary heat exchanger is a lamellar water-gas heat ex-
changer with copper pipes and fins (No. 77 fins on the 24 kW,
No. 89 fins on the 28 kW version and No. 105 fins on the 32 kW
version). The NTC central heating flow probe (2) and the safety
thermostat (3) are positioned on its outlet pipe (flow).
Primary heat exchanger is assembled with four tubes connected
in series (4).
Pipes with threaded fittings connect it to the pump flow and
the primary circuit flow.
