    Dual Boiler Espresso Machine Reviews

    Dual boiler espresso machines are characterized—as the name suggests—by two boilers. On this page, however, we also list other systems that consist of a combination of a boiler and a thermoblock or thin-film heater. What they have in common is that both boilers have individually controllable heating systems. The brew boiler, for example, operates at a solid brew temperature of 93°, while the steam boiler operates at 120 degrees. This ideally guarantees performance, consistency, and parallel steaming while brewing. Espresso machines with a boiler and a second, different heating unit are called multi-heating systems or, in the table, combo thermo-boiler or combo thin-film boiler.

    The following table shows all espresso machines that we have already tested in this category. By clicking on the name of the machine, you will 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 brew water and for generating the steam to froth the milk. By separating the boilers, the brew water for espresso preparation can be perfectly tempered. The steam boiler, on the other hand, is set to high pressure ranges and temperatures without affecting the brew temperature.

    Dual boiler espresso machines are typically used in gastronomy settings. Some manufacturers also offer dual boilers with a group for home use.

    Why do our tests take so long?

    Our comprehensive test protocol requires several weeks per machine. Additionally, we purchase all test devices ourselves, which is why we must balance different price segments. Quality over quantity – that way you get honest, independent test reports.

    Single-group dual boilers in gastronomy

    Powerful single dual boilers like the GS3 or Eagle One Prima are definitely suitable for use in gastronomy. Here, mainly professional-grade components are built into the machine, which also allow for higher frequency use.

    Choosing an espresso machine with just one group can certainly make sense, especially if it's unclear how strong the coffee interest of your clientele is. Should coffee develop into an interesting revenue stream, you can add a second machine to complement the first one.

    If there are periods in the morning or evening when fewer customers drink coffee, you can work with one machine. This saves electricity and cleaning. Also, in the evening, you can clean and shut down one machine or group early. Practical.

    Two boilers give you temperature control; the rest is up to the recipe. Standard recipe, grind size, and troubleshooting in Preparing espresso.
