Primary circuit (boiler circuit)
The primary circuit, with relative control and safety devices,
is started every time there is a central heating or domestic
hot water request.
Operation (see hydraulic diagram).
The heat contained in the combustion products is absorbed
by the pipes of the water-gas primary heat exchanger with
coil (13) which, then gives the heat up to the water made to
circulate inside the boiler pump (27). The water is introduced
directly into the system or can be diverted inside the storage
tank coil (2).
This depends on the position of the motorised 3-way valve

(31), which depending on request, allows flow towards the
system flow (M) and return (R) pipes or causes diversion
towards the coil (2).
Head-flow rate graphics.
The progress of the curve that represents the flow rate-head ratio
available to the system, depends on the functioning speed of the
pump and adjustment of the system by-pass which, according
to the position, allows to set greater or less head on he system.
The graphs below show the characteristic curves.
