Single Boiler Espresso Machines
A single boiler houses water for brewing espresso and steaming milk. It splits into two sections. The bottom section boils water, while the top section makes steam. Single boiler machines have smaller steam capacity than other types.
How a Single Boiler Works
A single boiler holds water. It heats via an element with two thermostats. One thermostat controls the brew water temperature range, while the other controls the boiling point for steam. When drawing a shot, fresh water flows directly from the boiler at a stable temperature.
Comparison: Single vs Dual Boiler
What is the difference between single and dual boiler espresso machines? Single boilers are suitable for home baristas looking for a compact, affordable espresso maker. However, they have limitations in performance and high volume coffee production. Purchase and maintenance costs are also relatively high.
Overall, the single boiler Espresso Machine GO offers great design and reliability, but minor issues exist, as with all single boiler models. Cooling the boiler after steaming can slow workflow, but the machine provides many benefits too. Shop around for deals on quality single boiler models if trying to save money.
