Breville Dual Boiler vs De'Longhi Dedica Style EC685
The Dedica Style ($199) is a beginner machine for small kitchens; the Dual Boiler ($1,499) is a prosumer machine for serious espresso. Do not compare them as alternatives unless your primary constraint is a $200 budget. If you can spend $1,499 and want real extraction control, the Dual Boiler is the correct choice without qualification.

These two machines occupy completely different categories. The Dedica Style is a thermoblock entry machine with a 51mm portafilter, pressurized baskets, and no temperature adjustment. It is designed to produce acceptable espresso with minimal effort and minimal space. The Dual Boiler is a triple-PID, dual-boiler prosumer machine with programmable pre-infusion and simultaneous brew-and-steam capability. The $1,300 price gap reflects a genuine capability gap.
The Dedica's strengths are physical: under 6 inches wide, it fits kitchens where the Dual Boiler cannot. Its 40-second thermoblock heat-up and volumetric dosing make the morning routine fast and simple. For someone making one or two milk drinks per day who has no interest in learning espresso technique, it delivers adequate results at a fraction of the cost. Most users outgrow it within one to two years as their palate develops.
The Dual Boiler requires a separate grinder and a willingness to learn puck preparation. In exchange, it gives you precise thermal control across three independent PID loops, the ability to pull a shot while steaming milk simultaneously, and enough programmability to replicate most specialty cafe extraction profiles at home. The 58mm group head opens a wide accessory ecosystem that the Dedica's 51mm portafilter cannot match.
Choose the Dedica if your budget is firm at $200, your kitchen has almost no counter space, or you are genuinely unsure whether you want to invest in the espresso hobby. Choose the Dual Boiler if you are ready to commit to serious home espresso and want a machine that will not limit your skills for the next five or more years.
