The CREM ONE 1B is a PID-controlled, single-boiler espresso machine with a vibration pump and a manufacturer-listed 1.7 L boiler. It is a substantial, 30 kg machine aimed at people who want manual espresso preparation and are comfortable checking configuration details—not a model whose independent taste, heating, or reliability results can be verified from the public review information available here. CREM calls it the “ONE 1B Dual”; CHOICE’s review title calls it the “Crem One Single Boiler (1B) PID.” Match the exact local SKU and electrical specification before buying.
What is the CREM ONE 1B?
The ONE 1B belongs to CREM’s one-group manual espresso machine range. CREM describes it as PID controlled, with a 1.7 L boiler and vibration pump. Its listed equipment includes soft pre-infusion in the group chamber, an E-61 group head, a digital temperature/time display, a water tank with a mains-water connection option, and a barista kit. Those are manufacturer specifications and feature descriptions; they do not, by themselves, establish cup quality or long-term reliability. CREM’s ONE 1B product page
Is the CREM ONE 1B a single-boiler machine?
Yes. The 1B has one steam boiler. Do not confuse that configuration with the ONE 2B models: CREM’s manual describes those as having a steam boiler plus a separate 1.5 L group boiler. Certain 2B rotary-pump variants add Gradual Soft Pre-Infusion (GSP) or Low Flow Pressure Profiling (LFPP); those features should not be assumed to be available on the 1B. CREM ONE user manual

How large is the ONE 1B, and what does it require?
CREM lists the 1B Dual at 30 × 45.8 × 42 cm (W × D × H) and 30 kg, with a 1.8 L water tank, 2150 W output, and 220–240 V, 50/60 Hz single-phase input. The listed operating pressure is 0.8–1.2 bar, and the internal water connection is 3/8 inch. The depth and weight make it important to check counter clearance, access for filling and servicing, and whether the surface can support the machine.

Electrical versions differ by market. The manual documents North American 110–127 V models with different power ratings, so do not order from the headline specification alone: confirm voltage, frequency, power, plug, and any plumbing requirements against the seller’s exact SKU and your local supply.

CHOICE lists a different set of dimensions—41 × 30 × 46 cm (H × W × D)—a weight of 21.9 kg, and a 1.7 L reservoir. Its figures do not align cleanly with CREM’s listing, which separately specifies a 1.7 L boiler and 1.8 L tank. The sources do not establish whether the discrepancy reflects a different version or measurement method; verify the physical dimensions and included configuration for the unit being sold.

What can the public review evidence tell you?
CHOICE identifies test areas including taste, ease of use, milk frothing, coffee-temperature consistency, heat-up time, and the time to froth 200 mL of milk. However, its expert rating, individual results, recommendation status, and pros and cons are member-only. The accessible material therefore does not support a numeric score or a conclusion that the machine makes better-tasting coffee, heats quickly, steams strongly, or is reliable. CHOICE review page
CREM calls the ONE a “fully professional-grade espresso machine,” but that is the manufacturer’s positioning, not an independent performance finding. Treat feature claims and independently measured results as different kinds of evidence. CREM ONE family page

What does it cost, and what warranty is listed?
CHOICE’s Australian review page lists a price of $3,685, but gives no visible collection date. It is a page-listed Australian reference, not a current quote or a price that can be generalized to other markets. CHOICE also lists a one-year warranty and China as the country of origin; confirm the warranty and service arrangements that apply to the specific unit and region you are considering.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Who should consider the 1B?
The specification profile is most relevant to a buyer who wants a manual, one-group machine, values PID temperature control and an E-61 group head, and is prepared to work within a single-boiler setup. Before deciding, compare the routine you expect with the machine’s architecture rather than inferring speed or steaming performance from boiler capacity alone.

What should you verify before ordering?
- Ask the seller for the exact model/SKU name and a photo or specification sheet for the unit being supplied; “ONE 1B Dual” and “Single Boiler (1B) PID” are names used by different sources for this product.
- Confirm voltage, frequency, power rating, plug, and whether you will use the tank or a mains-water connection. Compare those details with your household supply and the manual for that regional version.
- Measure available counter width, depth, and height, including room to fill the tank and reach the machine for cleaning or service. Confirm the unit’s actual weight and dimensions rather than relying on conflicting listings.
- Get the applicable local warranty, service contact, and parts-support terms in writing, and check current price and availability with the seller.
The manual lists basic cleaning supplies and water-related accessories in the supplied 1B kit. It does not establish compatibility for third-party replacement consumables, so check compatibility before buying replacements. CREM ONE user manual
