Our verdict
The UK Showermate Standard S2.0 bar Single, part 47340, is a compact positive-head pump for boosting one hot or cold supply in an open-vented system. Stuart Turner's dedicated single-pump data sheet is clear: two hoses, 19 L/min maximum flow, 2.0 bar closed head and 56 dB(A) typical noise. It is useful only where the plumbing design calls for one boosted supply; a normal hot-and-cold mixer often needs a twin.

What it is
This is a single-ended peripheral pump with a flow switch. Stuart Turner says single pumps can be used alone for hot or cold, or in pairs to pump the supplies independently. It is for positive-head, gravity-fed systems with more than 2 L/min natural flow at every outlet to be boosted.

The current web page's expandable specification incorrectly says “Pump heads: Twin” and “4” hoses, while the page title, part number, dedicated data sheet and installation guide identify 47340 as a single with two hoses. We use the model-specific documents and recommend confirming part 47340 before purchase.
Installation and safety
Stuart Turner says this pump must not be connected directly to the mains. It is for a vented stored-water system. The electrical installation must be done by a qualified person to current regulations, with a 30 mA RCD in the supply circuit.
The guide requires adequate storage, 22 mm supply pipework, correct dedicated feeds and cylinder take-off, priming before use and an accessible, ventilated location. It specifies permanent connection to a double-pole switched fused spur, separate from boiler and immersion circuits.
Use a qualified plumber and qualified electrician. This is not a DIY installation guide and not gas advice. See hiring a plumber and WRAS and water regulations.
Owner evidence
We did not use Amazon customer reviews or forum reports because we did not have a reliable, model-specific set to summarise. “Quiet” on the data sheet is maker language; 56 dB(A) is the maker's figure, not our measurement.
Pros and cons
Pros: compact single-supply pump; continuous rating at the stated duty point; dry-run protection; published curve; three-year warranty and stated water approvals.
Cons: positive head only; one supply rather than a hot-and-cold pair; current web specification contains a heads/hoses error; requires fixed electrical installation.
Who it suits — and who should skip it
It may suit one stored hot or cold supply on a correctly designed positive-head gravity system. Skip it when both supplies need boosting, natural flow is too low, or the system is mains-fed, combi or unvented. Have a plumber decide whether the single-ended arrangement is appropriate; start with shower pump sizing.
Alternatives
The Bristan 2.0 bar single is another one-supply option. For hot and cold together, see the Bristan 2.0 bar twin or Salamander CT75 Xtra. Compare all types in shower pumps compared, with noise and mains booster guidance alongside.
