Bosch Commercial and Industrial has made a series of enhancements to its popular GB162 light commercial gas boiler, for improved installation, servicing and operation.
Increased flexibility
For the first time, the GB162 is available as an 85kW model, meaning the boiler is now available in outputs of 50kW, 65kW, 85kW and 100kW. With the condensing boiler’s innovative cascade design, it can cater for large heat demands of up to 1.6MW, coming into and out of operation when required to ensure even load matching.
A key feature of the new GB162 is the introduction of overpressure flues which result in reduced installation height and increased flexibility. With each flue containing a flue gas non-return valve, the need for a large cascade flue header is removed, while flue gases are prevented from re-entering cascaded boilers which aren’t firing. This results in reduced installation costs due to smaller flue diameters, and makes the solution even better suited for buildings with narrower chimneys and in plant rooms with low ceilings and restricted space, making it retrofit friendly.
Advanced commissioning and servicing
The new boiler model also features an improved syphon with a threaded connection for a secure fit, offering peace of mind to the commissioning engineer, while 360° insulation helps to reduce heat loss and energy consumption. The addition of a single sided removable cover also improves access to internal components to simplify servicing and maintenance, particularly for cascades in tight plant rooms.
The GB162 now boasts a new pump group which offers the combination of lower hydraulic resistance and more residual pump head, which is ideal for single boilers and single heating circuit installations to reduce installation 
costs and energy bills, as there is no need to run an external system pump.
State-of-the-art control
Crucially, the updated GB162 is compatible with the leading connected commercial boiler control. The Control 8000 allows for medium and large commercial heating systems to be monitored and controlled remotely via a computer or tablet, helping service engineers to know exactly what is wrong with the heating system before they come to site.
Tim Davies, Business Development Director at Bosch Commercial and Industrial, comments: “The GB162 is an extremely popular product in our commercial boiler portfolio due to its ease of installation, reliability, and high performance. By listening to feedback from heating engineers and building a number of enhancements into the model, we have been able to make it even more versatile for a wider variety of large domestic and commercial installations, from large homes to schools and care facilities.”
