The Breville Barista Express uses a thermal coil heating system, while the Breville Barista Pro uses a Thermojet heating system. The key difference is that the Thermojet system is much thinner and more efficient, resulting in significantly faster heating times (3 seconds for the Pro vs. 30-45 seconds for the Express) and more consistent temperature control during espresso brewing.
This video compares the Breville Barista Express and Breville Barista Pro espresso machines. Marco, from Craft Coffee Spot, reviews both machines after four months of testing, highlighting key differences in design, espresso quality, milk frothing, grinder, display, and ease of use to help viewers decide which machine best suits their needs.
