INTRODUCTION
THE CASCADE SySTEM
The cascade system consists in the
installation of two or more modular
generators in parallel, connected to a
control system regulating its functioning
as if it was a single appliance.
The total heat output is equal to the sum
of each single generator output.
Distributing the heat output on more
than one unit brings many important
advantages:
Higher efficiency compared with
the use of a single generator of
great heat output, which would have
to work with a reduced heating load
for a good part of the heating period,
with consequent general lower
efficiency.
Less expenses thanks to the better
efficiency.
Greater safety as the subdivision
in more units allows to maintain the
heating function active even in case
of maintenance on one of the
connected appliances.
Greater flexibility with the possibility
of distributing the heating request
on all the appliances, while the
functioning sequence avoids the fast
deterioration of one boiler respect
the other.
