    Dual boiler espresso machine tests

    Dual boiler espresso machines are characterized - as the name suggests - by two boilers. However, on this page we also list other systems that consist of a combination of boiler and thermoblock or thick-film heater. What they have in common is that both boilers are individually controllable heating systems. For example, the brew boiler operates at a solid brewing temperature of 93°C, while the steam boiler operates at 120°C. Ideally, this guarantees performance, consistency and parallel steaming while brewing. We call espresso machines with a boiler and a second, different heating unit a multi-heating system or, in the table, Combi Thermo-Boiler or Combi Thick-Film Boiler.

    The following table shows all espresso machines we have already tested in this category. Click on the machine name to go to the respective article. "To Video" takes you to the YouTube video.

    What is a Dual Boiler?

    Dual boiler espresso machines have separate boilers for heating the brewing water and for generating steam for milk frothing. By separating the boilers, the brewing water for espresso preparation can be perfectly tempered. The steam boiler is instead set to high pressure ranges and temperatures without affecting the brewing temperature.

    Dual boiler espresso machines are typically used in commercial settings. Some manufacturers also offer single-group dual boilers for home use.

    Why Do Our Tests Take So Long?

    Our comprehensive test protocol requires several weeks per machine. Additionally, we purchase all test equipment ourselves, which is why we need to balance different price segments. Quality over quantity – that's how you get honest, independent test reports.

    Single-Group Dual Boilers in Commercial Settings

    Powerful single dual boilers like the GS3 or Eagle One Prima are definitely suitable for use in commercial settings. These machines primarily use professional components that also allow for higher frequencies.

    Choosing an espresso machine with only one group can make sense, especially when it's unclear how strong the coffee interest of the clientele is. Should coffee develop into an interesting revenue field, the one machine can be supplemented with a second one.

    If there are periods in the morning or evening when fewer customers drink coffee, work can be done with one machine. This saves electricity and cleaning. One machine or group can also be cleaned and switched off in the evening. Practical.

    This list is meant to be expanded. Please comment your wishes and suggestions. Which dual boilers should we test next?
