Powering Hundreds of Businesses Including:

Most home machines are designed to look the part, but they usually fail the moment you ask for consistency across more than one drink. The UNO is for the barista who has outgrown entry-level gear and is ready to stop guessing what the water temperature is doing inside the group head. Including an adjustable OPV allows you to finally stop wrestling with factory-set pressure and start tailoring the extraction to the specific bean in your hopper. This is the machine you buy when you’re done experimenting with toys and ready to start making actual espresso.

Product Features

Volumetric Programming & Pre-Infusion

Volumetric programmable settings handle single and double shots, pre-infusion, and auto-standby so you can automate repeatable shots without losing ritual. Pre-infusion helps gently saturate the puck for more even extraction and smoother crema.

PID Temperature Control

Digital PID temperature control lets you set brew temperature in one-degree increments so your morning shots hit the same extraction every time. The PID also includes offset control, removing guesswork when dialing in different beans or roast levels.

Thermoblock Boiler Stability

The aluminum & stainless steel thermoblock group provides continuous, unlimited steam with consistent pressure and minimal energy draw—ideal for steaming milk during a busy breakfast routine. The stainless steel thermoblock circuits resist limescale buildup for longer-lasting, reliable performance.

Adjustable OPV (Brew Pressure)

An adjustable over-pressure valve (OPV) lets you control brewing pressure to avoid over-extraction and tune mouthfeel shot-to-shot. It’s a simple mechanical way to refine extraction alongside grind and dose when you’re dialing in a new coffee.

58mm Professional Portafilter

A true 58mm professional portafilter with an ergonomic walnut wood handle gives home setups the same interface pros use for consistent puck prep and lever feel. The machine ships with five professional baskets (2 traditional, 2 pressurized, 1 monodose ESE), a stainless tamper, and a blank backflush basket to support dialing in or using pods.

Food-Safe Water Circuit & Quick Warm-Up

AISI 316 stainless steel water circuits and a freshwater draw for every shot preserve flavor and prevent metal migration so your espresso tastes clean. The 67-ounce reservoir is easy to fill and the unit reaches brew readiness in about 3:30, so quality shots don’t slow your morning routine.

The Coffeeionado Take

Who's It For:

  • Home users upgrading from entry-level espresso — PID temperature control and volumetric programming deliver consistent shots without manual temperature management
  • Daily home espresso drinkers — The 2–5 minute warm-up and 20–40 shot daily capacity handle a household's worth of drinks without breaking stride
  • First-time espresso buyers who want room to grow — The 58mm professional portafilter and adjustable OPV give you a real platform to develop your skills on

It's Right For You If:

  • You want fast heat-up and consistent temperature without managing a traditional boiler.
  • You're pulling 2–8 shots a day across milk drinks and straight espresso.
  • You value a compact footprint but don't want to sacrifice the standard 58mm portafilter ecosystem.

Things to Consider:

  • Thermoblock heating recovers quickly but has thermal mass limits — if you're pulling 6+ back-to-back milk drinks, expect slightly longer pauses than a dual boiler.
  • The vibration pump is audible during extraction — not loud, but noticeable in a quiet kitchen.
  • The 58mm portafilter is a genuine upgrade over 54mm machines, but you'll still want a capable grinder to take full advantage of it.

Our Take:

The UNO is the thermoblock machine we recommend when someone wants prosumer features — PID, 58mm portafilter, adjustable pressure — without the warm-up wait of a traditional boiler. It's the right call for busy households that want quality espresso without the ritual.

PID, an abbreviation for Proportional-Integral-Derivative, is a feedback loop controller utilized in espresso machines to regulate and maintain the water temperature within the boiler. It means you can regulate the temperature on the machine.
By doing so, it guarantees that the water temperature remains constant and ideal for producing high-quality espresso.

Program for Consistency

Volumetric programmable settings for preinfusion, single shot, double shot, and auto-standby, The enhanced volumetric controls make it easier to produce and repeat a consistently good quality espresso.

Water Quality & Machine Protection

Proper water quality is essential for optimal espresso extraction and long-term machine health. Use the guidelines below to ensure your machine performs at its best.

Parameter Ideal Range Why It Matters
Total Hardness 50-170 ppm Prevents scale buildup while maintaining flavor
pH Level 6.5-7.5 Ensures balanced extraction and protects internal components
Chlorine 0 ppm Eliminates off-flavors and prevents corrosion
TDS (Total Dissolved Solids) 70-150 ppm Optimal mineral content for extraction and taste
Total Alkalinity ~7.0 Stabilizes acidity and extraction
Chloride 0-28 ppm Prevents corrosion (especially in steel boilers)

Important Note

Always refer to your machine's manual for specific water quality recommendations and maintenance schedules.

Advisory

Install a water filtration system to maintain consistent water quality and extend the life of your espresso machine.

What This Means

  • Water that’s too hard → scale buildup, reduced performance
  • Water that’s too soft → flat, dull espresso
  • Improper water can damage internal components over time

Machine-Specific Considerations

  • These guidelines are safe for most home espresso machines
  • Some machines (especially with stainless steel boilers) require stricter limits on chlorides

What We'd Tell You In Store

How to Choose a Home Espresso Machine

The machine that's right for someone who wants great espresso with minimal daily effort is not the same machine that's right for someone who wants to learn pressure profiling. Before you look at specs or prices, two questions do most of the work: how involved do you want to be, and what's your realistic total budget — including the grinder.

Lever and Paddle Espresso Machines: How Much Control Do You Want?

A standard espresso machine makes one decision for you: how the shot is extracted. Paddle machines, spring levers, and direct lever machines give that decision back — in increasing degrees, and with increasing demands on the person holding the lever. This guide covers the full spectrum.

How to Pick Out a Home Grinder

The grinder is the part of your espresso setup that most people buy last and most people wish they'd bought better first. Every shot you pull — its extraction speed, its flavor, its consistency from one morning to the next — is determined first at the grinder. A great machine cannot fix a poor grind.

Setting Up Your Home Espresso Machine Right

The decisions made in the first few days — where the machine lives, what water goes through it, how the workflow is arranged around it — determine a lot about whether espresso becomes a daily ritual you look forward to or a recurring source of frustration.

Product FAQ

Does the Ascaso UNO Professional use a rotary pump or a vibratory pump?

The Ascaso UNO Professional uses a vibratory pump, not a rotary pump. Vibratory pumps are common in home and light commercial machines and are reliable, compact, and relatively quiet, though not as quiet as rotary pumps.

Does the UNO Professional have a pre-infusion function to improve espresso extraction?

Yes. The Ascaso UNO Professional offers a form of pre-infusion by allowing low‑pressure water to saturate the coffee puck briefly before full pressure is applied. This helps promote more even extraction and can improve flavor and crema consistency.

Is the Ascaso UNO Professional a heat exchanger, single boiler, or dual boiler machine?

The UNO Professional is a single-boiler machine with a large brass boiler. It is designed primarily for strong temperature stability during brewing, with the ability to switch modes for steaming. It is not a dual-boiler or traditional heat‑exchanger machine.

Can the Ascaso UNO Professional be direct plumbed into a water line, or is it reservoir only?

The standard Ascaso UNO Professional is a reservoir‑fed machine and does not come configured for direct plumbing. Water is supplied from the built‑in removable water tank, which you manually fill and clean.

Does the UNO Professional come with a cool-touch or no-burn steam wand?

The UNO Professional is typically equipped with a no‑burn or cool‑touch style steam wand. The wand is insulated so it does not get as hot to the touch as traditional wands, making it safer and easier to handle while steaming milk and reducing milk buildup on the exterior.

What size portafilter does the Ascaso UNO Professional use, and are the baskets standard?

The UNO Professional uses a commercial‑style 58 mm portafilter, which is compatible with most standard 58 mm baskets and tampers. This makes it easy to use third‑party baskets, precision baskets, and tampers if you choose to upgrade or customize your setup.

Does the Ascaso UNO Professional include a built-in grinder or do I need a separate grinder?

The UNO Professional does not have a built‑in grinder. You will need a separate, quality espresso grinder to get the best performance from this machine, as grind size consistency is critical for proper extraction.

How long does the Ascaso UNO Professional take to heat up and be ready to brew?

Under typical household conditions, the UNO Professional takes about 10–15 minutes to heat the boiler and group sufficiently for brewing. For optimal temperature stability—especially for back‑to‑back shots—many users allow 20–25 minutes of warm‑up time.

No, we don't ship to PO boxes. Due to the size and weight of our equipment, we require delivery to a physical address where our carriers can safely drop off your order.

How does free installation work?

We want to make your purchase as smooth as possible and will pay the installation via rebate on commercial espresso machines. This includes commercial machines with more than 1 group head and 220V.

If the certified installer needed is over 1.5 hours away then we will pay for the installation call (and install up to the value suggested on page minus call fee). Travel will be paid by customer. Inquire if you have any questions about your location.


Please note, any discounts subject to void the paid installation offer.

At Coffeeionado, professional installation is included with qualifying espresso machine purchases. Our goal is to make the process as seamless as possible — from coordinating the technician to getting your machine up and running on day one.

Which Machines Qualify

Free professional installation is included with all espresso machines of 2 groups or more where indicated on the product listing. This policy applies to espresso machines only and does not cover other coffee equipment such as grinders, brewers, or accessories.

If you are unsure whether your machine qualifies, contact us before purchasing and we'll confirm.

What's Included

  • Travel and labor costs for installation within the technician's service area (up to 2 hours of travel)
  • Setup, basic programming, and commissioning of the equipment
  • Scheduling during regular business hours, Monday through Friday
  • Associated taxes and fees related to the installation itself

Installation must be completed within 30 days of delivery of the equipment. The installation benefit lapses after this window and cannot be reinstated.

How Installation Is Arranged

Depending on your purchase, installation is handled one of two ways:

Arranged directly — In many cases, Coffeeionado or the manufacturer will coordinate and pay the technician on your behalf. We will contact you after your order is processed to schedule the visit.

Reimbursement — In some cases, you may be asked to arrange the installation locally using an authorized technician and submit a rebate form for reimbursement. Once approved, the covered amount will be refunded to the original payment method used for your order.

We will confirm which arrangement applies to your purchase at the time of order confirmation. If you have questions before purchasing, contact us and we'll walk you through it.

What's Not Included

The following are outside the scope of the installation policy and remain the customer's responsibility:

  • Travel or callout costs beyond the first 2 hours of the technician's travel time — if your location falls outside the local service area, the overage is your responsibility
  • Water filtration systems and installation materials — including plumbing fittings, tubing, plugs, outlets, and any other ancillary components required to prepare the site
  • Electrical or plumbing work — site preparation must be completed before the technician arrives
  • Training on equipment operation — installation covers commissioning only, not barista or operational training
  • False start or callout fees if the technician arrives and the site is not ready for installation

Important: If a technician arrives and cannot complete the installation because the site is unprepared, you will be responsible for any callout or false start fee charged by the technician. However, your installation benefit remains intact — the visit will be rescheduled at no additional cost to your policy.

Water Filtration Requirement

Water filtration must be installed and operational before or at the time of installation. This is not optional — operating a commercial espresso machine without proper filtration will void the manufacturer's warranty. If filtration is not in place at the time of the technician's visit, installation may need to be rescheduled and the callout fee will be your responsibility.

If you need guidance on water filtration requirements for your machine, contact us before scheduling your installation.

Service Area

Installation coverage is tied to the manufacturer's authorized technician service area, generally within a 1.5-hour radius of the nearest certified technician. If your location falls outside this area, Coffeeionado will make reasonable efforts to arrange a local authorized technician, but travel costs beyond the 2-hour coverage limit remain your responsibility.

Not sure if you're in a service area? Contact us before purchasing and we'll check your location.

After Installation

Once your machine is installed, we'll provide referrals for authorized service technicians in your area for ongoing maintenance and repairs. Coffeeionado offers lifetime support on all equipment we sell — we're here long after the install is done.

Governing Terms

This installation policy forms part of your agreement with Coffeeionado and is subject to our Terms of Sale and Terms of Service. In the event of any conflict, the Terms of Service governs.

Can I pick up the machine at your store?

We do not have a showroom or storefront for customer pickups, so orders cannot be picked up directly from us. That said, there is an exception for La Spaziale and La Pavoni products, you can contact us to arrange.

However, if you'd prefer, we can arrange to have your machine shipped to a local freight terminal/location for pickup instead. Let us know your city/state (or ZIP code), and we’d be happy to check the nearest terminal options for you.
