Servicing and maintenance
Spacious servicing - room inside the boiler for simple or thorough maintenance
All parts can be accessed from the front and the burners can be accessed without having to disturb the gas connection.
The boiler is equipped with SAFe digital ignition technology and a Bosch Energy Management System (EMS).
Performance and design
The GB312 is a high performance, compact condensing boiler which provides an efficiency of up to 108% (NCV).
Well suited to medium/large building - complementary accessories are available for cascade installations for up two boilers, however, large cascades can also be realised and intelligently controlled and sequenced.
For a powerful floor standing condensing boiler it is very compact, lightweight and easy to install.
