Dual-boiler espresso machines, or "multi-heating systems," are another category of espresso machines we'll be examining over time. In addition to classic dual-boiler espresso machines, we also test "multi-heating systems," meaning espresso machines with both a boiler and a thermoblock, such as the Ascasob Baby T.
We'll cover a variety of dual- and multi-boiler espresso machines, from entry-level to high-end. In this article, we'll collect suggestions for testing dual-boiler espresso machines.
Here you can read what else we tested.

What is a dual boiler?
Dual-boiler espresso machines have separate boilers for heating the brewing water and generating the steam for frothing milk. By separating the boilers, the brewing water can be perfectly tempered for espresso. Instead, the steam boiler is set to high pressure ranges and temperatures without affecting the brewing temperature.
Dual-boiler espresso machines are typically used in restaurants. Some manufacturers also offer dual-boiler models with a single group for home use.
Single group dual boiler in the catering industry
Powerful single-dual boilers like the GS3 or Eagle One Prima are definitely suitable for use in the hospitality industry. These machines primarily use professional components that also allow for higher frequencies.
Opting for an espresso machine with only one group can certainly make sense, especially if it's unclear how much coffee your customers are interested in. Should coffee develop into an attractive sales area, the one machine can be supplemented with a second one.
If there are periods in the morning or evening when fewer people are drinking coffee, one machine can be used. This saves electricity and cleaning costs. A machine or group can also be cleaned and turned off in the evening. Practical.
This list is intended as a supplement. Please comment with your wishes and suggestions. Which dual boilers should we test?
