Londinium · LeverR24
A spring-lever HX machine with a quiet 24V rotary pump and app-controlled variable digital pre-infusion (1.0–6.0 bar) — lever character without cooling flushes or backflushing.
The short version
The R24 is a well-engineered HX spring-lever that trades manual lever rawness for digitally dialled pre-infusion control and a pump that barely registers.
The one thing a buyer must accept is an hour-long cold warm-up and a single-source supply chain through one company founder.
Why people buy it
- No cooling flushes, warming shots, or backflushing — the HX thermosiphon keeps the group stable through consecutive shots and idle periods alike
- Variable digital pre-infusion (1.0–6.0 bar) adjustable from a phone app allows instant roast-to-roast changes without waiting for group temperature to resettle
Why they don’t
- One-hour cold warm-up from a standing start is realistic and non-negotiable without the app timer scheduled in advance
The full tally
- No cooling flushes, warming shots, or backflushing — the HX thermosiphon keeps the group stable through consecutive shots and idle periods alike
- Variable digital pre-infusion (1.0–6.0 bar) adjustable from a phone app allows instant roast-to-roast changes without waiting for group temperature to resettle
- 24V rotary pump is genuinely quiet and runs only during boiler fill and pre-infusion — extraction itself is silent once the spring takes over
- Strong owner-serviceability ethos: video call support, HD service video library, and fast DHL global parts shipping from a small dedicated manufacturer
- One-hour cold warm-up from a standing start is realistic and non-negotiable without the app timer scheduled in advance
- Single-source supply chain: spare parts, firmware, and direct support all run through one founder — business continuity is a genuine long-term risk
- No plumb-in option on the R24 — tank-only design with a 3.0L reservoir and no direct-connect upgrade path
What the community knows
Years of owner threads, distilled — well regarded.
Owners value shot consistency, reliability, and maintainability; digital pre-infusion and quiet operation stand out. Strong Reiss-led support and straightforward serviceability offset single-person business risk and modest visibility relative to pump-machine defaults—a cult…

Worth knowing before you buy — Most owners wish they'd started with a better grinder first—the machine rewards input discipline more than it covers deficits.
Known weak points — Rare app connectivity issues (circa 2021, resolved); isolated pump failures handled well by manufacturer; no documented boiler or seal failures in current corpus
“I have found it easy to use, it is incredibly quiet and it also looks great! I have been playing around with the adjustable pre infusion On the app to dial in some SO Beans and found it improves the taste considerably!”

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners who want deeper pressure profiling and shot graphing typically look at the Decent DE1 or the Londinium commercial I/II/III range. Those chasing a purer mechanical lever experience without the digital layer sometimes move to the Londinium Compressa or other plumb-in spring levers.

Before it arrives
What completes this machine — the faded pieces can wait.
Gooseneck kettle · not optional — Manual and lever machines bring no water of their own — a temperature-stable gooseneck is how you actually pull a shot.

- Descaler & backflush kit — Electric boilers scale up and grouts gunk up — a descaler plus backflush routine is what keeps the machine alive for a decade.
- Knock box — Somewhere to bang the spent puck that is not your kitchen bin.
- WDT distribution tool — Breaks up clumps before tamping — a cheap fix for channeling on any portafilter machine.
- Espresso cups & glassware — Proper demitasse and latte glasses keep the drink hot and look the part.
Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new machine gets blamed for it. A machine in this class will show you the difference between roast dates — it deserves beans that change week to week.

Common questions
Does the Londinium R24 require plumbing in?
No. The R24 is tank-fed by design with a 3.0L reservoir. There is no plumb-in option on this model. The water tank includes a BWT softening cartridge for hard-water protection.
How long does the R24 take to warm up?
Londinium recommends allowing one hour from cold before pulling shots. The app's smart timer lets you schedule heat-up in advance so the machine is ready when you are.
What pre-infusion range does the R24 offer?
Pre-infusion pressure is digitally adjustable from 1.0 to 6.0 bar via the Londinium phone/tablet app with no tools required. Changes take effect on the next shot without waiting for group temperature to shift.
Does the R24 require backflushing or cooling flushes?
No. The spring-lever design and thermosiphon architecture mean no backflushing is required, and the group holds temperature through consecutive shots and idle periods without warm-up or cool-down flushes.
What grinder does the R24 pair well with?
A quality midrange or single-dose grinder capable of consistent fine espresso grind is recommended. The Niche Zero is a frequently noted owner pairing. The 58mm commercial group will reveal grinder quality clearly, so an entry-level grinder will be the limiting factor.
