Redring Pure Instant Electric Shower 7.5kW to 10.5kW — White A-rated Push Button
The Redring Pure is a compact, mains-fed instantaneous electric shower — cold water connects directly from the rising main, is heated on demand as it passes over the heating element, and is dispensed immediately. No hot water cylinder, no storage tank, no wait. Available in four kW variants: 7.5kW (RPS7), 8.5kW (RPS8), 9.5kW (RPS9), and 10.5kW (RPS10) — select your variant above. All four share the same white ABS housing, push-button start/stop, twin rotary controls for temperature and power setting, three power settings plus cold, and right-hand side water and cable entry. The higher the kW, the greater the temperature rise at a given flow rate — choosing the right variant depends on your incoming mains water pressure, the planned electrical supply, and local incoming water temperature (colder in winter and in northern regions means a higher kW is needed for the same shower temperature). All supplied complete with 600mm adjustable riser rail, 1m anti-kink hose, and single-mode rub-clean handset. A energy rating, BEAB approved, 2-year manufacturer's warranty.
⚠ Qualified electrical installation required — Must be installed by a suitably qualified electrician in accordance with BS 7671 (IET Wiring Regulations) and Part P of the Building Regulations. The shower must be permanently connected to a dedicated circuit from the consumer unit via a double-pole isolation switch with minimum 3mm contact separation, sited out of reach of a person using the shower. Cable size and MCB rating are determined by the kW variant and cable run length — see the electrical table below. Do not connect any other appliance (extractor fan, pump, etc.) to the shower circuit — this invalidates the warranty.
⚡ Rising cold water main only — not from a storage tank
The Pure must be fed directly from the rising cold water main — not a cold water storage tank or header tank. Minimum static pressure at the unit: 1 bar; maximum: 10 bar. Minimum flow rate: 8 L/min for 7.5kW and 8.5kW; 9 L/min for 9.5kW and 10.5kW. A WRAS-listed isolating valve must be fitted between the rising main and the unit. Use PTFE tape on threaded joints only — plumber's jointing compound is not compatible with the unit's fittings and will invalidate the guarantee.

ℹ Choosing the right kW — the key consideration
A higher kW heats each litre of water by more — producing either hotter water at the same flow, or the same temperature at a higher flow. In practice, the mains water temperature coming in varies from around 6°C in winter to 17°C in summer. To deliver a 39°C shower temperature from 6°C incoming, approximately 33°C of heating is needed. The 7.5kW is suitable for good-pressure mains supplies in temperate climates where a restricted flow is acceptable. The 9.5kW or 10.5kW is better for northern UK locations, cold winters, or anywhere the incoming mains water is significantly below average. If replacing an existing electric shower, matching the kW is the simplest approach — subject to confirming the existing circuit rating. Note: only the 10.5kW requires a 45A MCB; the 7.5, 8.5 and 9.5kW all work on a 40A circuit.

Features & Benefits
✔ Instantaneous — No Cylinder Needed
The Pure is an instantaneous (tankless) electric shower: water is heated on demand as it flows over the heating element, so there is no wait for a tank to heat up and no risk of running out of hot water mid-shower. Because it uses only the cold rising main, it can be installed completely independently of the existing hot water system — useful for properties where adding a shower to a new bathroom without extending hot water pipework is required, or where the cylinder is slow or unreliable.
✔ Three Power Settings + Cold Rinse
The power selector rotary control offers three heating levels — full power, Economy 1, and Economy 2 — plus a cold-water-only position for rinsing the enclosure. Economy settings are useful in warmer months when incoming mains water is naturally warmer and less heating energy is needed to reach a comfortable shower temperature. At full power, the unit delivers its rated kW output; at Economy settings, power is reduced, lowering the flow rate or temperature slightly but using less electricity per minute.
✔ Push-Button Start/Stop — Simple Controls
A single push button starts and stops the shower — no separate power switch to operate once the isolation switch is on. A rotary temperature control then allows fine adjustment to the preferred water temperature. The control layout — one button, two dials — is deliberately straightforward, with no menus, app pairings, or digital displays, making the Pure suitable for a wide range of users including those less familiar with technology, and children aged from 3 years (with appropriate supervision).
✔ Right-Hand Connections — 4 Water, 3 Cable Entry Points
Water and electrical cable enter from the right-hand side, with four water entry options (top, bottom, rear, side) and three cable entry points selectable by cutting the appropriate knockout in the back plate before final fix. The adjustable top bracket covers existing fixing holes from a previous shower — reducing the chance of wall repairs in tiled bathrooms when replacing an older unit. The installation does not require the unit to be recessed and must be surface-mounted onto the finished wall.
✔ BEAB Approved — A Energy Rated — IPX4
BEAB (British Electrotechnical Approvals Board) approval confirms independent testing to UK electrical safety standards for bathroom appliances. The A energy rating reflects the inherent efficiency of instantaneous showers — only the water being used is heated, with zero standing losses compared to stored hot water systems. IPX4 (splash protection from any direction) is the required minimum rating for electric showers in bathroom zones. Maximum operating noise level: 15 dB(A).
✔ Rub-Clean Handset — 600mm Adjustable Riser Rail
The rub-clean single-mode handset removes limescale from the nozzle face by rubbing with a finger — no tools or descaler required. The 600mm adjustable riser rail with height-adjustable soap dish allows the handset to be positioned for different users. Rail, handset, and 1m anti-kink hose are all supplied in the box — no additional shower accessories are required for a complete, working installation. The hose attaches to the central outlet on the shower back plate via the sealing washer provided.
