Energy-saving system technology
Highly efficient boiler systems with perfectly matched boiler house components
ensure low energy consumption and low emissions.
Save energy costs through the
firing ...
... up to 40 % by switching fuel
Switching to another fuel can often have a pay-
back period of only a few months while genera-
ting savings over decades. If multi-fuel firing is
retrofitted, peak loads can be covered by a
second fuel or own biogas can be used.
... up to 4 % by optimising the firing
Combustion control balances out changes in
operating conditions such as temperature, pres-
sure and gas quality. An intelligent system
control and a high modulation range reduce
unnecessary cold starts and pre-ventilation
losses when starting up.
... reduce the power consumption by up to
75 % through efficient electrical consumers
Conventional firing fans do not adapt their output
to the boiler load. Speed-controlled motors and a
burner control not only save you power, the boiler
will also be significantly quieter at partial load. for reducing burner starts increase the service life
Save fuel costs through heat
recovery ...
... from flue gas up to 14 %
The flue gas temperature can be reduced by
more than 100 K through the use of a flue gas
heat exchanger (economizer). A downstream
condensation heat exchanger extracts further
energy from heat and condensation.
Maximum availability of the system ...
... through remote service
On the customer’s demand a Bosch service
expert can gain direct access to the system via a
secure connection to identify e.g. false param-
eters quickly. In some cases these faults can be
eliminated remotely, or the service technician is
able to provide the correct spare part at the first
on-site visit.
... through preventive condition monitoring
The intelligent boiler control evaluates sensor signals
during operation to detect wear or the need of
maintenance at an early stage. These notifications
enable higher reliability of the system and trouble-
free operation.
... through automatic functions that reduce
wear on materials
Frequent cold starts at high load levels create
stress for boilers and their components. Auto-
matic boiler start functions and control algorithms
of the system.
... through remote monitoring
An immediate message on a cell phone in the case
of a fault makes it possible to react quickly – so
that operation remains interruption-free.
