La Spaziale S1 Vivaldi II

The S1 Vivaldi II is La Spaziale's bench dual boiler with a 0.45 l coffee boiler and a 2.5 l main boiler, built for a fixed water connection ("Water connection" per the official spec sheet) as well as the tank. Preinfusion is electronic and managed at the group, with temperature shown on an LED display and built-in fault diagnosis.

An authorized retailer (Whole Latte Love) adds details absent from the official page: an E61 group, a 53 mm portafilter, a rotary pump, and a double gauge on the brew and steam circuits. As these specifics are not confirmed directly by the manufacturer, they should be treated as indicative rather than equivalent to an official spec sheet figure.

At 41.5x41.5x38.5 cm and 28 kg it shares its physical footprint with the Mini sibling, differing mainly in main boiler capacity (2.5 l versus 1.2 l) and, per the retailer, in running a rotary rather than a vibration pump. The manufacturer states two voltage variants, 230V or 110V, both at 50/60Hz, drawing 2200W. The manufacturer does not state operating pressure, heat-up time, or whether a PID control is fitted.
