GB312: Efficiency and Performance
Buderus knows it’s important to keep costs as low as possible yet still maintain
high efficiencies, low emissions, and exceptional performance. That’s why we
have worked hard to bring all of these qualities together in the GB312 gas fired
condensing boiler from Buderus.
Powerful, Convenient, Economical
The gas fired condensing GB312 boiler offers innovative technology in a compact,
robust form with simple, space-saving, advanced condensing technology. Features
like exemplary energy efficiency, ease of handling, optional balanced flue operation
and clean combustion make the GB312 your definitive solution.
Ease of Installation and Servicing in a Compact Design
Everything about the GB312 is designed for greater simplicity and economy,
including ease of operation and installation. Matching components and factory
settings make installation quick and easy. The modulating premix gas burner is
ready for natural gas and can be quickly removed for cleaning, easy servicing, and
maintenance. Other components are equipped with their own clean-outs. Although
the GB312 delivers a lot, it takes up remarkably little space. Its compact design
makes it an ideal choice for tight installation areas, plus it easily fits through
standard doorways.
Continuous System Monitoring and Control
The EMS (Energy Management System) uses sensors to monitor the status of the
boiler. If the system values deviate greatly from the set values, the system issues a
fault or service message. When faults occur that have impact on safety, the SAFe
control triggers either a blocking or safety shutdown.
