At ease in both the home and the cafe, The La Spaziale Vivaldi II is a triumph of both design and function. The wood panels shown below are exotic Bubinga wood.
The Vivaldi II features two boilers, a rotary pump, programmable preinfusion, and must be directly connected to a water source. With its impressive steaming power and 2.5 L boiler, you'll have enough steam to make cappuccinos for the entire neighborhood.
Shot dosing is volumetric and programmable, so you can store your shot times for consistent results. A programmable temperature controller also allows you to set the group boiler temperature to really fine tune your extraction.
Double boiler espresso machines have one boiler each for steam and espresso. You can steam and pull shots simultaneously. Additionally, the steam boiler has a dedicated power switch, which gives the user the option to provide power only to the group head boiler if milk steaming won’t be necessary. Double boilers typically control the temperature digitally for the most consistent temperature. If you want the best, consider a double boiler.

PID Temperature Control:
A PID (Proportional Integral Derivative) controller closely monitors and electronically regulates the water temperature at the brew group. A PID sends short bursts of power to your boiler, keeping the temperature within a very narrow range. With a machine like the Izzo Duetto, you can control the temperature to within 1 degree of accuracy. Heat exchangers cannot be used with a PID, and instead rely on a mechanical pressurestat to regulate temperature. Single boilers can have PID control, and are an upgrade option on machines like the Quick Mill Alexia.
PIDs are not required for a good espresso shot, but they do allow you to precisely dial in your brew temperature. This is especially important for single origin espressos and straight shot enthusiasts.
Rotary pumps are typically found on espresso machines with a direct water connection. The main advantage of a rotary over a vibratory pump is quieter operation when powered. They also have the added benefit of an immediate ramp up to brew pressure when engaged. Vibratory pumps generally require 3-5 seconds to achieve extraction pressure. Rotary pumps may be found on all commercial machines due to their ability to keep up with volume.
No other independent testing programs require companies to comply with the strict standards imposed by NSF and its product certification programs. From extensive product testing and material analyses to unannounced plant inspections, NSF is the only third-party testing organization to undertake a complete evaluation of every aspect of a product's development before it can earn a certification.
A Product that is certified or listed means that NSF:
- Reviewed the Product, most often through a sampling of the Product and its components, materials, and compounds.
- Determined at the time of the review that the Product complies with the relevant NSF consensus standard and/or protocol ("Standard"); and
- Conducted or will conduct periodic audits to review whether the Product continues to comply with the Standard.
A product bearing the ETL Listed Mark is determined to have met the requirements of prescribed product safety standards. Moreover, the mark indicates that the manufacturer's production site conforms to a range of compliance measures and is subject to periodic follow-up inspections to verify continued conformance.
PID Temperature Control
- A closed loop temperature controler gives the user remakable control over espresso extraction and steam.
- When paired with a PID, isolated boilers provide superior temperature precision and predictability.
- An efficient and pulse free design that provides consistent pressure across the entire duration of extraction.
- Dual boiler:
- Dedicated boilers for steam and espresso mean that recovery time is rapid and temperature stability is excellent.
- Programmable shot dosing:
- With the ability to pre-program shot times, it's easy to get consistently good espresso.
- Temperature control:
- It's simple to adjust the temperature in the group boiler with a front-access touch pad.
- Programmable pre-infusion:
- You may program in a pre-infusion time that works best with your coffee and technique.
- Plastic Side Panels:
- The stock side panels are black plastic. If this bothers you, consider our custom wood side panel upgrades.
- Short shot drop distance:
- The distance between the portafilter spouts and the drip tray grate is very short, making it hard to pull shots directly into a cup. Consider a bottomless portafilter to solve this.
- 53 mm portafilter:
- While it doesn't affect the shot quality, 53mm portafilters are an unusual size and it's slightly more difficult to find accessories.
