La Marzocco GB5 S Espresso Machine

A La Marzocco GB5 S in two or three group configurations on 220 V single phase, with a 3.4-litre coffee boiler and 7-litre steam boiler at two groups, rising to 5 L and 11 L at three, weighing 70 kg and 91 kg respectively. The GB5 is La Marzocco's high-volume workhorse — built for sustained output rather than the profiling features of the Strada line.

Who it suits

For high-volume cafes, hotels and chains where the machine runs all day and reliability matters more than extraction theatre. Single-phase operation simplifies installation considerably for a machine of this class. A bar wanting pressure profiling should look at the Strada instead; the GB5 is built to produce consistent shots at pace.

Common questions

How does it differ from the Strada S?
The GB5 is built for sustained volume; the Strada adds pressure profiling. Both run single phase, but they suit different bar philosophies.

Does it run on single phase?
Yes, 220 V single phase, which removes the three-phase requirement that often complicates installation at this class.

How do the boiler sizes compare with the Linea Classic S?
Identical boiler capacities. The GB5 differs in build and group design rather than boiler volume.

How heavy is it?
70 kg for two groups, 91 kg for three, before water. Confirm the counter can carry it.
