    Dual Boiler Espresso Machine Reviews

    As the name suggests, dual-boiler espresso machines feature two boilers. However, on this page, we also include other systems consisting of a combination of a boiler and a thermoblock or a thick film heater. What they have in common is that both are independently controllable heating systems. For example, the brew boiler runs at a steady brewing temperature of 93°C, while the steam boiler operates at 120°C. Ideally, this guarantees performance, consistency, and the ability to steam while brewing. We call espresso machines with a boiler and a second, different heating unit "multi-heating systems" or, in the table, "Combi Thermo-Boiler" or "Combi Thick Film Boiler".

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

    What is a dual boiler?

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

    Dual-boiler espresso machines are generally used in gastronomic contexts. Some manufacturers also offer dual boilers with a single group for home use.

    Why do our tests take so long?

    Our detailed test protocol requires several weeks per machine. In addition, we buy all test equipment ourselves, which is why we have to balance different price segments. Quality over quantity – in return, you get honest, independent test reports.

    Single-group dual boilers in gastronomy

    Strong single-group dual boilers like the GS3 or Eagle One Prima are definitely suitable for use in gastronomy. Professional components are used throughout the machine, which also allows for higher frequencies.

    Opting for an espresso machine with only one group can make sense, especially if it is unclear how strong the customers' interest in coffee is. If coffee develops into an interesting revenue field, the single machine can be supplemented by a second one.

    If there are phases in the morning or evening when fewer customers are drinking coffee, you can work with one machine. This saves electricity and cleaning. It is also possible to clean and switch off one machine or group in the evening. Practical.

    This list is intended as a supplement. Please comment your wishes and suggestions. Which dual boilers should we test next?
