Single-Boiler Espresso Machines - a compact focus on espresso

Single-boiler machines use a central heating system for brewing coffee. In models with a steam function, the same system is used for espresso and then for steam, which means a temperature change is required between brewing and frothing milk. This makes this design particularly appealing to users who mainly drink espresso and are looking for a compact, straightforward setup.

In this collection, you will find the Profitec GO 2.0, Gaggia Classic Evo Pro e24, Lelit Anna, and Lelit Victoria, among others. The ECM Puristika takes a particularly dedicated espresso-focused approach and does not have a steam function - so it should not be described generically like a classic single-boiler machine that switches between brewing and steaming.

Single-Boiler or Heat-Exchanger?

If you mainly prepare espresso and only occasionally make milk drinks, a single-boiler machine may suit your daily routine very well. If, on the other hand, you often prepare several cappuccinos in a row, a heat-exchanger machine is more convenient because espresso and steam are available without the same temperature change.

Single-Boiler or Dual Boiler?

Dual-boiler machines offer separate heating circuits for coffee and steam, providing greater convenience and temperature control when used simultaneously. Single-boiler machines, on the other hand, are often more compact and focus more strongly on a simple espresso workflow. Which design suits you better therefore depends less on the price than on your drinks, how much you use the machine, and the level of operating convenience you want.
