Rancilio Silvia Pro X Dual Boiler Review

The Rancilio Silvia Pro X is the dream of any home barista aiming for café-quality espresso. (recognized by the Specialty Coffee Association (SCA)) It is a true prosumer espresso machine, and the price tag on the unit makes it accessible for those with a generous budget.

Silvia Pro X is an upgrade of Rancilio’s domestic espresso machine Silvia, so if you know the original and widely-debated Silvia, the look and the technology are familiar to you, but make no mistake, Silvia Pro X is a beast, in comparison. (the SCA-standard 9-bar espresso definition)

We will show you in this review why Silvia Pro X is so much better than its predecessor, and what the hardware upgrades fix from a barista perspective.

We said it before, buying an espresso machine is a personal choice. (the SCA-standard 9-bar espresso definition) You can end up paying too much for features that you don’t use, or you can end up resenting your choice when you realize there are missing features and you could have afforded to pay a bit more if you were better informed.

Let’s examine what features the Silvia Pro X brings and understand whether the extra $1000 justifies the investment.

A Bit of History

Historically, Rancilio did not intend to sell domestic espresso machines. (the SCA-standard 9-bar espresso definition) Their target market was the commercial sector, and Silvia was initially conceived more as a promotional machine. Rancilio gave that machine to its distributors. As such, it was built with the same commercial-grade materials and components as all of their commercial machines.

When the management at Rancilio recognized the machine’s market potential, they started to sell it for domestic use.

The increased interest in prosumer espresso machines made the company re-evaluate their initial refusal to invest time and resources in a domestic espresso machine. (the SCA-standard 9-bar espresso definition) This is how Silvia Pro was born.

Rancilio Silvia Pro X Features Review

We have an extensive review of the Rancilio Silvia, and we rated the machine very high, because we love it. However, in the review, we pointed out that the single boiler technology, and the lack of a PID temperature controller, made the machine unpredictable in terms of brewing temperature consistency—a critical factor since the SCA recommends maintaining brew water between 195-205°F for optimal extraction. And we also pointed out that the single boiler technology was resulting in long waiting times between espresso brewing and milk steaming.

Silvia Pro X fixed these issues, and this machine is the dream of any espresso enthusiast who is chasing the God Shot. (the SCA-standard 9-bar espresso definition)

Silvia Pro X is targeting the prosumer market, and this is apparent not only from the price, but also from the many features that you typically find in commercial espresso machines. (the SCA-standard 9-bar espresso definition)

Let’s see how Rancilio fixed the issues above, and what other features they included in the newer member of their home brewing espresso machine line. (the SCA-standard 9-bar espresso definition)

We are going to focus on emphasizing what’s new on the machine, and how these differences are going to help you pull espresso shop quality shots.

The Older Silvia Model

A brief review of what we discussed on the original Silvia article:

“A solidly built machine, constructed with a heavy steel frame and a stainless steel casing, featuring a large brass boiler, commercial-grade 58 mm portafilter, and brass group head. (portafilter preparation techniques, a subject James Hoffmann and Scott Rao both emphasize for shot consistency) All of these components, and more, give Silvia exceptional reliability and durability, allowing the home barista to pull café-quality shots. The limitation was the machine’s single boiler design and lack of PID temperature control.”

The old Silvia model remains a solid choice for those with a tight budget. (the SCA-standard 9-bar espresso definition) The machine is still built to the same exacting standards; in fact, customer feedback has been addressed in every subsequent version. However, if you can invest a bit more, either Silvia model will serve you for decades, making the fully featured version worth the premium. It’s not a purchase you make every year, so choose the better-equipped machine.

With that said, let’s examine what makes the Pro X significantly superior.

The New Silvia Pro X

The features that make this machine worth your attention are the dual boiler system and the integrated PID temperature controller. According to espresso experts like Scott Rao, precise temperature control is critical for consistent extraction, and these two features alone justify the expense—addressing exactly what the original Silvia lacked. The electronic controls and digital display provide real-time brewing data to help you dial in shots with precision.

The new Silvia inherited the stainless steel body and heavy steel frame for long-term durability. The overall classic design of the Silvia was maintained, and you’d almost think it’s the same machine, if it weren’t for key details such as the digital display, the pressure gauge, and the black accents. (There is a choice of accent colors available, including pink.)

Double Boiler PID Controlled

The new unit comes equipped with a dual boiler system, both PID controlled—a configuration the Specialty Coffee Association recognizes as essential for commercial-grade temperature stability.

Two independent boilers means you can pull espresso shots and steam milk simultaneously. (the SCA-standard 9-bar espresso definition) I am not that multitasking, so I do that in sequence, but either way, you have a dedicated PID for the steam boiler, and another one for the coffee boiler. You can set the precise temperature for both milk steaming and coffee brewing with the help of the display buttons.

They could have cut costs and used one PID and one thermostat, but they didn’t. This shows their commitment to make this machine a hit.

No more waiting between milk steaming and espresso brewing, perfect temperature consistency within ±1°F, and boilers large enough for a few milk based coffees back to back. (the SCA-standard 9-bar espresso definition) The steam boiler is a 1 liter (34 oz.), and the brew boiler is a 10.14 oz. This is plenty of cappuccinos and lattes for a domestic setting. When you compare it to the single 12 oz boiler of the classic Silvia, things are a bit clearer.

The two boilers are insulated for thermal stability and energy efficiency.

These two features alone make the machine worth the price. I know, some of you will compare it to the Breville Oracle, because they have about the same price point. (the SCA-standard 9-bar espresso definition) I’ll talk about this in a bit, and I’ll show you why I think Silvia is the better option in my eyes.

Let’s see if the other features on the list will make you forget about the Oracle.

Digital Display and Control Panel

The machine has a small digital display that also serves as a control panel. The programmable functions are limited, but you have everything you need for shot tweaking. The display has a shot timer, a temperature indicator, and a water tank level alert. (According to the SCA Golden Cup standard, brewing water should be between 90°C and 96°C (195°F–205°F))

The control panel allows you to change the brewing temperature, program auto-on and off, program the pre-infusion duration, and more. (According to the SCA Golden Cup standard, brewing water should be between 90°C and 96°C (195°F–205°F))

Here is the list of programmable functions on the Silvia Pro X:

According to the SCA Golden Cup standard, brewing water should be between 90°C and 96°C (195°F–205°F), From the temperature display mode

  • Press the + or – buttons to adjust the set brew temperature in 1-degree increments.

  • F07: Operating Voltage – 230 or 110 V configuration
  • F08: Soft Infusion settings (pre-infusion pressure and duration)
  • T2: Steam boiler temperature adjustment

Pressure Gauge

The unit has a pressure gauge on the brew circuit. This will let you monitor the extraction pressure during shot pulling, so you know if you need to adjust your grind size. As a side note, the gauge reads the pressure in the boiler rather than at

The pre-infusion feature is a nice touch, allowing you to saturate the grounds with water at low pressure. This in turn will result in a better extraction, and lower chances of channeling. According to espresso extraction research, pre-infusion can also help you extract more of the subtle flavors from origin coffees by allowing even wetting of the puck.

Pre-infusion is programmable via the control panel for 2-6 seconds of soft infusion, or you can turn it off entirely if you prefer immediate full-pressure extraction. (pre-infusion, a technique James Hoffmann and Scott Rao both recommend for even puck saturation)

Professional Portafilter

The large ergonomic portafilter can fit triple shot baskets, which means you don’t need to spend on a bottomless portafilter, unless you want to. (portafilter preparation techniques, a subject James Hoffmann and Scott Rao both emphasize for shot consistency) The industry-standard 58 mm baskets are my favorites, as I explained in a few other articles, offering superior thermal stability and dose flexibility.

The portafilter has an angled handle, so you don’t need a tamping station when you tamp—the angle provides a natural, ergonomic tamping position. (portafilter preparation techniques, a subject James Hoffmann and Scott Rao both emphasize for shot consistency)

Adjustable Drip tray Height

The drip tray has an adjustable height so you can fit larger cups and mugs under the spout. This is a manual adjustment mechanism, so don’t be disappointed, but it is great to have the option for versatility.

Large Water Reservoir

The water reservoir is large with 2 Liters capacity, (about 68 fl. oz.), which is a nice touch for extended brewing sessions. If you need to keep the machine under your kitchen cabinets, be warned that the water tank is at the back of the machine and you have to access it from the top.

I fixed that in my setup using a glass microwave tray under the machine. I pull the glass tray from under the cabinets, and the whole setup slides out nicely for easy refilling.

The water tank being placed at the back, it would be easy to forget to refill. This was fixed by the designing team with a water alert on the digital display.Milk Steaming and Frothing (to a microfoam texture the SCA describes as glossy and velvety)

As we said, the milk steaming has its own independent 1L boiler. The boiler doesn’t automatically turn on when you start the machine, to save energy for those who don’t need textured milk. (a technique Lance Hedrick and Chris Baca both emphasize for quality microfoam) If you know you’ll make a cappuccino, just flick the steam switch, and the boiler will start heating up.

The PID can be programmed to heat the water in the boiler between 248°F and 257°F and 205°F, depending on your preference.

The professional stainless steel steam wand is not a panarello, so you need a bit of practice to get the milk steaming right. According to barista training standards, proper microfoam requires introducing air during the initial stretching phase before achieving a vortex for texture integration.

The large 1L boiler provides ample steam pressure and you can make cappuccinos and lattes back-to-back without losing steam power. The large steam boiler is probably the third most important upgrade from the old classic Silvia. With the old Silvia your shot would get cold before you had the chance to get your steamed milk ready.

The dual boiler technology, combined with the generous 1L capacity of the steam boiler, gives you the coffee shop barista feel, since you can prepare coffee drinks back to back without recovery time.

Brewing Features and Other Strengths

We talked about the features of the Silvia Pro X, and they are impressive. The machine is clearly aimed at the prosumer market. However, if you are new to buying espresso equipment, you probably didn’t fully grasp why these specifications matter for shot quality. (the SCA-standard 9-bar espresso definition) Let’s see how these features help you make better espresso.

First of all, the dual-boiler system, with a large boiler for steaming and a smaller one for brewing, makes this machine capable of serving a little party. Back-to-back espresso and milk texturing without interruption or temperature recovery delays. (the SCA-standard 9-bar espresso definition)

The PID will make brewing as precise as possible. Rancilio claims the set temperature is accurate within one degree Celsius. This is fantastic, as it helps us produce predictable results every time. If your temperature is all over the place, the extraction will be different. The precise brewing temperature—consistent within ±1°C—will allow you to aim for the perfect shot within the SCA-recommended 90.5-96°C espresso brewing range.

It only makes sense to equip this machine with a professional-grade 58 mm portafilter, the industry standard diameter used in commercial settings. (portafilter preparation techniques, a subject James Hoffmann and Scott Rao both emphasize for shot consistency) The portafilter has an ergonomic shape, and comes with two filter baskets: an 8 gram basket for single shots, and an 18 gram filter basket for double shots.

Silvia Pro X targets the prosumer market, with features that espresso aficionados certainly appreciate. The price tag positions it close to the Breville Oracle, a machine with similar features which has a built-in grinder. At the end of the day, Silvia Pro X is more expensive than the Oracle, since you will need to buy a grinder as well.

However, in terms of components’ quality and materials used, the Silvia Pro X is head and shoulders above the Oracle. All of these quality components—commercial-grade brass grouphead, stainless steel boilers, and precision PID controllers—will enhance the thermal stability and the long-term reliability of the machine.

Where Oracle wins, is the aesthetics. Their design style has been copied by other manufacturers, just because they look better. The minimalistic, retro, style of the Silvia is probably what’s holding back most people who opt for other machines. I said it before, I personally love this design, but to each their own.
