Deciding whether the Sanremo F18 SB fits your setup means matching its features with your workflow, space, and budget. To help you judge, here are the buyer considerations, the strong points, and the trade‑offs you should know.

What to keep in mind:

  • Service volume match: Choose the 2‑group version if your peak hour is moderate; the 3‑group handles higher throughput.

  • Counter & power infrastructure: Requires 35” or 42” width, 25” depth, and 220 V power (3.2 kW vs 5.6 kW for 2‑ vs 3‑group),  make sure your space and wiring align.

  • Installation & filtration requirements: The machine’s heat‑exchange design benefits from filtered water, suitable pressure, and maintenance clearance to perform its best.

  • Budget vs lifespan: With premium build, die‑cast aluminium legs, and an energy‑saving system (up to 20% savings), you’ll invest upfront, but operating costs and durability matter.

  • Skill level of baristas: Its advanced features (pre‑infusion control, volumetric dosing) reward experienced operators or those willing to train.

Pros:

  • Strong heat‐exchange system: With thermosiphon flow, driving stable extraction under pressure.

  • Volumetric design: Volumetric dosing with programmable pre‑infusion helps maintain consistent shots even during rush periods.

  • Energy‑saving mode: smart insulation cuts electricity use, good for long shifts.

  • Built for serviceability: group flushing, easy access panels, intuitive display.

  • Visual impact: die‑cast aluminium supports, available finishes, modern look that enhances space.

Cons & Solutions:

  • Higher power requirement for 3‑group (220 V / 26 A / 5.65 kW): May require electrical upgrade.

    • Solution: Confirm your circuit or plan for a dedicated line before purchase.

  • Larger footprint for 3‑group (42” width x 25” depth): Could exceed tight bar spaces.

    • Solution: Map your counter early, ensure space behind for clearance and operator movement.

  • Single‑boiler heat‑exchange system (note: heat‑exchange, not multi‑boiler) means steam and brew share capacity.

    • Solution: Sync workflow so shots are pulled efficiently and milk texturing is timed well.

  • 12‑month parts warranty only: Some machines offer longer.

    • Solution: Budget for maintenance and parts beyond year one if you anticipate heavy use.

Note: While the F18 SB is single-boiler, pairing it with a skilled workflow ensures fast, consistent milk drinks even during café rush hours.

Set Up Essentials - Tools & Accessories to Maximize the Machine’s Value

Setting up the Sanremo F18 SB for optimal performance means more than placing it on a counter; it’s about building a system around it that supports fast, quality service and sustainable operation. For cafés or mobile bars, the right accessories can make a real difference; for small teams, they streamline every shot and steam sequence.

Here are recommended add‑ons, workflow upgrades, and space optimizations to pair with your F18 SB:

  • Quality Grinder with Dosing Accuracy: A grinder that delivers consistent doses helps the F18 SB’s volumetric controls work properly and maintains shot repeatability.

  • Water Filtration & Softening System: Given the heat‑exchanger boiler and sensitive internal parts, proper filtration protects the machine and preserves coffee flavour.

  • Digital Scale & Workflow Timer: Use a scale for calibrating yield and a timer for tracking service speed in café rush hours, giving you better control of output.

  • Knock Box & Dump Station: Efficient puck disposal ensures the group heads remain clear during continuous pulls, keeping the machine ready for the next shot.

  • Milk Frothing Tools (Pitcher, Thermometer, Micro‐foam Mat): Since the F18 SB supports steam and brew simultaneously, good frothing tools improve speed and drink quality.

  • Cup Warmer & Organized Bar Station: Use the machine’s built‑in cup warmer and keep the area tidy to ensure that every drink is served hot and looks professional.

FAQs

1. What maintenance schedule should I follow for the Sanremo F18 SB?

The F18 SB includes programmable automatic cleaning cycles that simplify daily upkeep, but consistent maintenance is essential for long-term performance. Perform group head flushing and backflushing at the end of each service day. In addition, schedule a monthly deep inspection that includes checking the boiler, valves, gaskets, and water filtration system. Regular boiler inspections help prevent scale buildup and protect the heat-exchange system from premature wear.

2. What espresso ratio and extraction timing work best on the F18 SB?

For modern specialty espresso, a reliable starting point is an 18–20g coffee dose for a double shot, targeting a 36–40g yield in 25–30 seconds. The F18 SB’s volumetric dosing and pre-infusion control make it easier to maintain this ratio consistently, but final adjustments should always be dialed in based on roast level, grinder performance, and taste preference.

3. What water quality is required for the F18 SB to perform optimally?

To keep extraction results and machine longevity on track, filtered water with correct hardness and minimized chlorine is essential. Impurities can affect taste and accelerate wear in internal components like the SR 61 grouphead and volumetric pump. Installing a dedicated filtration and pressure regulator system is highly recommended for this model.

4. How much counter space and clearances are needed for installation?

For the 2‑group variant, the recommended footprint is 35″ (length) × 25″ (depth) × 20.25″ (height); for the 3‑group variant, 42″ × 25″ × 20.25″. In addition to surface space, allow clearance behind and above for servicing and routine maintenance. A well‑planned bar layout ensures smooth operations and easier access.

3. Can the F18 SB brew espresso and steam milk at the same time?

Yes, but with an important distinction. Because the F18 SB uses a single-boiler heat-exchange system, brewing and steaming are efficient and can occur near-simultaneously—but they are not unlimited like a true dual-boiler setup. During high-volume service, workflow management is key. Timing espresso extraction and milk steaming strategically helps maintain temperature stability and consistent drink quality.
