Greenstar Si Compact
Features and benefi ts
The Greenstar Si Compact is the successor to the Greenstar Si combi boiler.
The all new Greenstar Si Compact has a host of performance-enhancing
features, including the revolutionary WB7 heat exchanger which enables the
appliances to deliver DHW fl ow rates of 10.2 and 12.3 l/min despite their
compact size.
Similarly to the CDi Compact, particular care has been taken with the design
of the hydraulic unit. Key components are positioned to provide easy access,
whilst the Heatronic 4i control box makes commissioning simpler. This menu-
driven unit features an LCD display which shows boiler status symbols and
system and commissioning parameters as well as giving access to service and
maintenance codes and diagnostics.
Building on installer feedback, the new Greenstar Si Compact has been
designed to make installation and commissioning easier and quicker and
comes supplied with a unique wall-mounting jig which enables the installer
to quickly pre-plumb all seven pipe connections without the boiler being
on the wall.
The Greenstar Si Compact offers an A rated annual effi ciency of up to
90.5% (SEDBUK 2005 value).
