Espresso machines with a single boiler are good enough to make espresso, but if you want to make espresso-based drinks that involve milk such as cappuccino, latte, and so on, the process must take turns. It is better to do the extraction process first, then steaming it later. It’s because if it’s steaming first, the temperature will already drop and generally tends to be unstable for the next espresso extraction process. For your information, after doing one process, commercial espresso machine boilers generally have to neutralize the temperature first to zero before starting a new heating process.
Pros: The price of single boiler machines generally does not drain too much money. It’s suitable for those who want to open a cafe with a tight budget. This type of boiler is also mostly portable, so the engine is easy to carry anywhere.
Cons: A single boiler requires a gap of several minutes between the extraction and steaming processes. In other words, this machine will take a little time if we want to make cappuccinos and other espresso-based drinks. Therefore, this type of boiler-type espresso machine is not suitable for use in busy shops, or for those who have quite a lot of customers every day. Forcing a machine with one boiler on a busy coffee shop will usually end in fast-paced engine performance, which makes the machine reaches its limit faster.

As for the one with double boilers, it’s an espresso machine with a double boiler option, and it’s sometimes called a dual boiler. Of course, it has two separate boilers. One special boiler serves to maintain the extraction temperature (brewing), and another specifically for the steaming process. Therefore, espresso machines with this type also generally have a stable temperature. Both boilers can also be used at the same time, so the machine can work better and faster. Breville dual boilers up to all La Marzocco series are examples of coffee machines that have this feature.
