Breville’s BES920XL Dual Boiler has commercial-grade features and performance in the domestic footprint. Espresso perfect requires precise temperature and pressure control always, and consistently. At the core of this espresso machine are the dual boiler heating system made of stainless steel. The espresso boiler used for shots of espresso is temperature-controlled, and a separate steam boiler provides rapid and strong steam upon demand. You can then make your espresso at the perfect temperature and get the most flavor, and simultaneously heat your milk to cafe-quality.
Furthermore, there’s an additional component in the group head to ensure that the whole system is at the same temperature. It also has an Over Pressure Valve (OPV). Dual Boiler also features an Over Pressure Valve (OPV) that limits the maximum pressure during the extraction process, thus reducing the bitter taste of the shot. The Dual Boiler also has a low-pressure pre-infusion that slowly increases the pressure to gradually expand the grinds to ensure an evenly-extracted extraction.

We’ve made it easy to use with simple features. An option for the Auto Start setting allows you to warm the appliance at a pre-programmed time. A top-fill 84 8 oz. (2.5L) storage tank for water allows for ease of access. Additionally, the designated hot water outlet helps speed up the process of heating cups and making an Americano.
