It requires a \u003cstrong\u003ededicated 20 A double-pole isolator\u003c\/strong\u003e with a minimum 3 mm contact separation, fed by an RCD-protected circuit. Cable cross-section must be selected by the installing electrician in accordance with \u003cstrong\u003eBS 7671\u003c\/strong\u003e for the specific run length and installation method.

All three share \u003cstrong\u003eidentical physical dimensions\u003c\/strong\u003e (143 × 190 × 82 mm) and the same PROFI-RAPID installation system.

The DEM 4 Set supports both \u003cstrong\u003eoversink and undersink installation using the same unit\u003c\/strong\u003e. Rotating the appliance 180° changes the orientation. The \u003cstrong\u003ePROFI-RAPID back panel acts as a drill template\u003c\/strong\u003e, with elongated slots to compensate for drill-hole inaccuracies, and external G 3\/8 A water fittings accommodate either position without requiring separate hardware.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #ddd;border-radius:6px;margin-bottom:8px;overflow:hidden;\"\u003e\u003csummary style=\"background:#008377;color:#fff;padding:12px 16px;cursor:pointer;font-weight:600;list-style:none;\"\u003eDoes the DEM 4 Set work with non-pressurised (open outlet) taps?\u003c\/summary\u003e\u003cdiv style=\"padding:14px 16px;color:#333;line-height:1.6;\"\u003eYes.

There is no anode rod or sacrificial component to inspect or replace. However, the \u003cstrong\u003eminimum water resistivity specification must be satisfied\u003c\/strong\u003e (≥ 1000 Ω·cm at inlet temperatures ≤ 25 °C; ≥ 1300 Ω·cm at inlet temperatures above 25 °C) — always verify the local mains water supply conductivity before installation.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #ddd;border-radius:6px;margin-bottom:8px;overflow:hidden;\"\u003e\u003csummary style=\"background:#008377;color:#fff;padding:12px 16px;cursor:pointer;font-weight:600;list-style:none;\"\u003eWhat routine maintenance does the DEM 4 Set need?\u003c\/summary\u003e\u003cdiv style=\"padding:14px 16px;color:#333;line-height:1.6;\"\u003eMaintenance requirements are minimal. The bare wire element is \u003cstrong\u003eentirely maintenance-free\u003c\/strong\u003e.

Test your flow rate with a 1-litre measuring jug and stopwatch. \u003cstrong\u003eThe TSMEB-9 (9.6 kW) is the most popular model\u003c\/strong\u003e and is the right choice for most UK homes where the outlet flow rate reaches 4–5.5 l\/min. If your flow rate is lower (e.g. a restricted hand basin), a TSMEB-6 or TSMEB-7 may be sufficient. If you need higher flow rates than any single unit can provide, two units installed in tandem give up to 11 l\/min.

For shower or kitchen sink applications, a higher-output unit is required.\n  \u003c\/div\u003e\n\n  \u003c!-- ── STAT STRIP ─────────────────────────────────────────────────── --\u003e\n  \u003cdiv style=\"display:flex;flex-wrap:wrap;gap:10px;margin-bottom:20px;\"\u003e\n    \u003cdiv style=\"flex:1;min-width:85px;background:#008377CF;color:#fff;border-radius:6px;padding:11px 8px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:15px;font-weight:700;\"\u003e3.1 \/ 4.8 \/ 6.0 kW\u003c\/div\u003e\n\u003cdiv style=\"font-size:12px;margin-top:3px;\"\u003eThree models\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv style=\"flex:1;min-width:85px;background:#008377CF;color:#fff;border-radius:6px;padding:11px 8px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:17px;font-weight:700;\"\u003e38°C\u003c\/div\u003e\n\u003cdiv style=\"font-size:12px;margin-top:3px;\"\u003eFactory set output\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv style=\"flex:1;min-width:85px;background:#008377CF;color:#fff;border-radius:6px;padding:11px 8px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:17px;font-weight:700;\"\u003eIP24\u003c\/div\u003e\n\u003cdiv style=\"font-size:12px;margin-top:3px;\"\u003eSplash protected\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv style=\"flex:1;min-width:85px;background:#008377CF;color:#fff;border-radius:6px;padding:11px 8px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:17px;font-weight:700;\"\u003eWRAS\u003c\/div\u003e\n\u003cdiv style=\"font-size:12px;margin-top:3px;\"\u003ePotable water approved\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv style=\"flex:1;min-width:85px;background:#008377CF;color:#fff;border-radius:6px;padding:11px 8px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:17px;font-weight:700;\"\u003e132 × 187mm\u003c\/div\u003e\n\u003cdiv style=\"font-size:12px;margin-top:3px;\"\u003eSame body, all models\u003c\/div\u003e\n\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- ── FEATURES GRID ──────────────────────────────────────────────── --\u003e\n  \u003cdiv style=\"background:#008377CF;color:#fff;font-weight:600;font-size:15px;padding:10px 16px;border-radius:6px 6px 0 0;\"\u003eFeatures \u0026amp; Benefits\u003c\/div\u003e\n  \u003cdiv style=\"display:grid;grid-template-columns:repeat(auto-fill,minmax(255px,1fr));gap:12px;background:#e6f4f3;padding:14px;border-radius:0 0 6px 6px;margin-bottom:22px;\"\u003e\n\n    \u003cdiv style=\"background:#f0faf9;border:1px solid #c8e6e3;border-radius:6px;padding:13px;\"\u003e\n      \u003cdiv style=\"font-weight:700;color:#008377CF;margin-bottom:5px;\"\u003e✔ Bare-Wire Element — Instant Heat, Zero Standby Loss\u003c\/div\u003e\n      \u003cdiv style=\"font-size:14px;\"\u003eThe Zip ES uses a \u003cstrong\u003ebare-wire (immersed) heating element\u003c\/strong\u003e — the element is in direct contact with the water flowing through it rather than heating a metal surface that then heats the water.

The quoted flow rates (1.7 \/ 2.6 \/ 3.3 L\/min at 38°C) assume a 12°C inlet temperature at 3 bar. In summer or on mains supplies that are naturally warmer, the same models will deliver slightly higher flow rates at 38°C. In cold winter conditions or at high altitude, the heater works harder and flow rate may be marginally lower at the same temperature setting. For a normal basin handwash, all three models produce adequate flow — the \u003cstrong\u003eES3\u003c\/strong\u003e is the most economical where a lower flow is acceptable; the \u003cstrong\u003eES6\u003c\/strong\u003e gives the most comfortable flow rate and suits busier installations or locations where users expect higher flow. The ES4 is the most commonly specified middle option for commercial washrooms.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails style=\"border-bottom:1px solid #c8e6e3;\"\u003e\n      \u003csummary style=\"padding:13px 16px;cursor:pointer;font-weight:600;background:#fff;\"\u003eWhat is the water quality requirement and how do I check?\u003c\/summary\u003e\n      \u003cdiv style=\"padding:11px 16px;font-size:14px;\"\u003eBecause the bare-wire element is in direct electrical contact with the water, the water must be a \u003cstrong\u003esufficient electrical insulator\u003c\/strong\u003e. Zip specifies a minimum specific resistance of \u003cstrong\u003e\u0026gt;1300 Ω·cm at 15°C for ES3\u003c\/strong\u003e and \u003cstrong\u003e\u0026gt;1000 Ω·cm at 15°C for ES4 and ES6\u003c\/strong\u003e. Very soft water (low in dissolved minerals, as found in some upland\/rural areas of the UK, particularly Scotland and Wales) can have lower specific resistance than this and would not be suitable. Ordinary mains water in most UK towns and cities easily exceeds these thresholds. To check: contact your local water supplier and ask for the specific resistance or conductivity figure for your area, or your local council water quality report will often list it. Water with specific conductivity above 100–150 µS\/cm at 25°C may require checking against Zip's threshold.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails style=\"border-bottom:1px solid #c8e6e3;\"\u003e\n      \u003csummary style=\"padding:13px 16px;cursor:pointer;font-weight:600;background:#f0faf9;\"\u003eCan I use this with a mixer tap or thermostatic tap?\u003c\/summary\u003e\n      \u003cdiv style=\"padding:11px 16px;font-size:14px;\"\u003eThe ES range is \u003cstrong\u003enot recommended for use with thermostatic mixing valves or thermostatic taps\u003c\/strong\u003e. This is because thermostatic valves blend hot and cold to a fixed temperature — but the Zip ES already delivers water at a pre-set temperature (38°C), so adding a thermostatic valve creates a conflict between two temperature-regulating devices. For non-thermostatic mixer taps (standard hot\/cold basin mixer), a \u003cstrong\u003enon-return valve must be fitted on the hot water outlet\u003c\/strong\u003e to prevent cold water back-flowing into the heater when both hot and cold sides are used simultaneously. A flow control valve may also be needed on the cold supply to balance pressure. The unit is supplied with a jet regulator for M22 or M24 threaded tap outlets, which gives optimum flow control at low rates.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails style=\"border-bottom:1px solid #c8e6e3;\"\u003e\n      \u003csummary style=\"padding:13px 16px;cursor:pointer;font-weight:600;background:#fff;\"\u003eIs there a Legionella risk with this type of heater?\u003c\/summary\u003e\n      \u003cdiv style=\"padding:11px 16px;font-size:14px;\"\u003e\n\u003cem\u003eLegionella pneumophila\u003c\/em\u003e multiplies in stored water held between approximately 20–45°C.

The HSE's L8 ACOP and HSG274 guidance specifically recognises instantaneous heaters as inherently lower risk than stored systems. However, \u003cstrong\u003ethe upstream cold supply pipe and any dead-legs between the mains connection and the unit must be managed\u003c\/strong\u003e in a full water safety risk assessment, particularly in healthcare and care home settings.

All are available as Zip spare parts via Zip Heaters (UK) Ltd. The filter sieve should be checked and cleaned periodically, particularly in hard water areas. A full fault finding guide is provided in the installation manual — the most common issues are low flow rate (blocked filter or jet regulator) and failure to switch on (flow below the minimum threshold).\u003c\/div\u003e\n    \u003c\/details\u003e\n\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"Zip Water","offers":[{"title":"3.1KW","offer_id":62647799611741,"sku":"ES3","price":330.0,"currency_code":"GBP","in_stock":true},{"title":"4.8KW","offer_id":62647799644509,"sku":"ES4","price":360.0,"currency_code":"GBP","in_stock":true},{"title":"6.0KW","offer_id":62647799677277,"sku":"ES6","price":385.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/2051\/3629\/files\/ZipESInlineInstantaneousHandwash3.1kWto6.0kW.png?v=1763645513"},{"product_id":"heatrae-sadia-handy-no-touch-handwash-3-1kw-instantaneous-automatic-sensor-water-heater","title":"Heatrae Sadia Handy No Touch Handwash - 3.1kW Instantaneous Automatic Sensor Water Heater","description":"\u003cdiv class=\"product-description\"\u003e\n\u003cp\u003eThe \u003cstrong\u003eHeatrae Sadia Handy No Touch Handwash 95020115\u003c\/strong\u003e is a \u003cstrong\u003ecompact 3.1kW instantaneous electric handwash unit\u003c\/strong\u003e featuring touchless infrared sensor activation for hygienic, no-contact operation.

Designed specifically for the UK market, the Aures Multi heats water as it flows through the unit — providing hot water only when a tap is opened, and stopping as soon as the tap is closed.

Designed as a true point-of-use heater, the PowerPack is ideal for locations where running a hot water supply from a central system would be impractical, expensive, or wasteful — such as garages, outbuildings, cloakrooms, utility rooms, bedsits, and remote commercial handwashing facilities. With a white moulded ABS casing, a glass-reinforced nylon inner vessel, integrated safety thermostat, and a built-in 2.5 bar pressure relief valve, the PowerPack is a robust and well-proven product that has been a staple of UK plumbing and electrical installation for decades. It operates on a single-phase 240V supply and requires a dedicated 40A circuit.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"sa-stat-bar\"\u003e\n    \u003cdiv class=\"sa-stat\"\u003e\n\u003cdiv class=\"num\"\u003e7kW\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eHeating Power\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"sa-stat\"\u003e\n\u003cdiv class=\"num\"\u003e240V\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eSingle-Phase Supply\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"sa-stat\"\u003e\n\u003cdiv class=\"num\"\u003e210×160\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eH×W (mm)\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"sa-stat\"\u003e\n\u003cdiv class=\"num\"\u003e1–7 bar\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eOperating Pressure\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"sa-stat\"\u003e\n\u003cdiv class=\"num\"\u003e88°C\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eSafety Cut-Out\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"sa-stat\"\u003e\n\u003cdiv class=\"num\"\u003e40A\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eCircuit Protection\u003c\/div\u003e\n\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eWhat Is the Santon PowerPack and How Does It Work?\u003c\/h2\u003e\n  \u003cp\u003eThe PowerPack is an \u003cstrong\u003einstantaneous\u003c\/strong\u003e (also called \"tankless\" or \"multipoint\") water heater — meaning it heats water on demand as it flows through the unit, rather than storing a pre-heated volume in a cylinder. Cold mains water enters the unit through the ½\" BSP inlet, flows past a copper-sheathed heating element inside the glass-reinforced nylon inner vessel, and exits as hot water at the ½\" BSP outlet. There is no waiting for stored water to reheat, and no heat loss from a standing cylinder — water is hot immediately from the moment flow starts, and heating stops the moment flow stops.\u003c\/p\u003e\n  \u003cp\u003eThe unit is \u003cstrong\u003eunvented\u003c\/strong\u003e, meaning it operates at mains pressure and does not require an open-vented cold water header tank. It connects directly to the mains cold water supply and discharges hot water at mains pressure — suitable for both shower and spray tap outlets. One outlet can be supplied at a time: the PowerPack is not designed to supply multiple simultaneous draw-off points.\u003c\/p\u003e\n  \u003cp\u003eThe 7kW heating element produces a useful temperature rise at normal flow rates. At a moderate flow of around 2.5 litres per minute — typical for a spray tap or economy shower head — the PowerPack will raise the water temperature by approximately 23–28°C above the incoming cold water temperature. With a UK cold supply temperature of around 10–15°C in winter, this delivers an outlet temperature of around 35–43°C, which is comfortable for handwashing. Reducing the flow rate with the integral flow restrictor increases the temperature rise further.\u003c\/p\u003e\n\n  \u003ch2\u003eKey Features \u0026amp; Benefits\u003c\/h2\u003e\n  \u003cdiv class=\"sa-grid\"\u003e\n    \u003cdiv class=\"sa-card\"\u003e\n\u003cstrong\u003e⚡ 7kW Instantaneous Heating\u003c\/strong\u003eHeats water on demand as it flows through the unit — no cylinder, no heat-up wait, no stored water to lose heat overnight.

For shower use in winter, consider whether the 7kW output will deliver adequate temperature at your required flow rate.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n  \u003ctable class=\"sa-spec-table\"\u003e\n    \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n    \u003ctbody\u003e\n      \u003ctr\u003e\n\u003ctd\u003eMPN\u003c\/td\u003e\n\u003ctd\u003e94050211\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSanton (by Heatrae Sadia)\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003ePowerPack 7kW\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eColour\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eInstantaneous (tankless) unvented water heater\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eRated power\u003c\/td\u003e\n\u003ctd\u003e7kW\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eSupply voltage\u003c\/td\u003e\n\u003ctd\u003e230\/240V AC single-phase\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eRated current\u003c\/td\u003e\n\u003ctd\u003e~29A at 240V\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eRequired circuit protection\u003c\/td\u003e\n\u003ctd\u003e40A double-pole MCB or fused isolator\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e210mm (H) × 160mm (W) × 104mm (D)\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eWater connections\u003c\/td\u003e\n\u003ctd\u003e½\" BSP inlet and outlet\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eOperating pressure (min)\u003c\/td\u003e\n\u003ctd\u003e1 bar (0.1 MPa)\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eOperating pressure (max)\u003c\/td\u003e\n\u003ctd\u003e7 bar (0.7 MPa)\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003ePRV setting (supplied)\u003c\/td\u003e\n\u003ctd\u003e2.5 bar (supplied with 7kW model)\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eSafety cut-out temperature\u003c\/td\u003e\n\u003ctd\u003e88°C (manual reset thermal cut-out)\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eElement type\u003c\/td\u003e\n\u003ctd\u003eCopper sheathed rod element\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eInner vessel material\u003c\/td\u003e\n\u003ctd\u003eGlass-reinforced nylon\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eOuter casing material\u003c\/td\u003e\n\u003ctd\u003eWhite moulded ABS\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eOutlets\u003c\/td\u003e\n\u003ctd\u003eOne at a time (shower or spray tap — not simultaneous)\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eStandards\u003c\/td\u003e\n\u003ctd\u003eEN 60335-2-35; BEAB approved; BS\/European Standards\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003c\/tbody\u003e\n  \u003c\/table\u003e\n\n  \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n  \u003cdiv class=\"sa-faq-item\"\u003e\n    \u003ch3\u003eCan I use the PowerPack 7kW to run a full-pressure mains shower?\u003c\/h3\u003e\n    \u003cp\u003eIt depends on the shower head.

Standard full-flow shower heads and any type of body jet or rainfall head require higher flow rates than the 7kW element can heat to a comfortable temperature, so the outlet temperature will be too cool, particularly in winter. The PowerPack is much better suited to spray taps and economy showers than to a full-performance shower outlet. For a dedicated 7.5kW or 8.5kW electric shower, consider a purpose-built electric shower unit instead.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"sa-faq-item\"\u003e\n    \u003ch3\u003eDo I need a plumber and an electrician for installation?\u003c\/h3\u003e\n    \u003cp\u003eTypically both. The water connections (cold supply, PRV, discharge pipework) should be made by a suitably qualified plumber familiar with Water Supply Regulations and Building Regulations Part G. The electrical supply (dedicated 40A circuit, double-pole isolator, RCD protection, earthing and bonding) must be carried out by a qualified electrician working to BS 7671. In practice, many plumbers hold both water and electrical qualifications for heater work — confirm this with your installer before proceeding.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"sa-faq-item\"\u003e\n    \u003ch3\u003eWhat is the difference between the 7kW and 9kW PowerPack models?\u003c\/h3\u003e\n    \u003cp\u003eThe 9kW model (a separate product) provides a higher temperature rise at the same flow rate, or the same temperature rise at a higher flow rate — making it better suited to shower applications where higher flow is desired. The 9kW requires a 50A circuit (versus 40A for the 7kW). For handwashing spray taps and cloakroom\/garage applications at typical UK flow rates, the 7kW model is usually more than adequate and has a lower electrical infrastructure cost.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"sa-faq-item\"\u003e\n    \u003ch3\u003eCan this be installed in a bathroom or shower room?\u003c\/h3\u003e\n    \u003cp\u003eYes, subject to the zone requirements of BS 7671 Part 7 (Section 701). The PowerPack is not IP-rated for installation within Zone 1 (directly above a bath or shower tray). It can be installed in Zone 2 or outside the defined zones in a bathroom, provided the electrical installation meets the relevant zone requirements and appropriate circuit protection is in place. In a shower room or wet room where the unit is not in a defined hazardous zone, installation is straightforward.

The heater will deliver hot water at any flow rate between 2.5 L\/min and 16 L\/min continuously.\u003c\/div\u003e\n    \u003c\/details\u003e\n    \u003cdetails style=\"border-bottom:1px solid #c8e6e3;\"\u003e\n      \u003csummary style=\"padding:13px 16px;cursor:pointer;font-weight:600;background:#fff;\"\u003eCan this heater be converted to LPG?\u003c\/summary\u003e\n      \u003cdiv style=\"padding:11px 16px;font-size:14px;\"\u003eThis unit is factory-set for \u003cstrong\u003enatural gas (G20)\u003c\/strong\u003e.

The heater adds a fixed amount of thermal energy per litre flowing through it — the faster the flow, the smaller the temperature rise per litre. As a practical example: at a 12°C cold inlet and 40A rated current (9kW), running at 3 L\/min gives approximately a 42°C rise, delivering ~54°C at the heater outlet. Reduce flow to 2 L\/min and the rise increases; open a second tap and total flow rises, reducing the rise per litre. \u003cstrong\u003eYou adjust temperature by adjusting flow\u003c\/strong\u003e at the tap — the touch screen set point tells the heater the ceiling, not a guaranteed delivery temperature regardless of flow. The Strom's modulating element helps compensate for flow variation, but physics limits what any instantaneous heater can do at very high flow rates.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border-bottom: 1px solid #c8e6e3;\"\u003e\n\u003csummary style=\"padding: 13px 16px; cursor: pointer; font-weight: 600; background: #fff;\"\u003eCan I use this as the sole source of hot water in a property?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 11px 16px; font-size: 14px;\"\u003eYes — the Strom Touch Screen is designed for \u003cstrong\u003emultipoint whole-property hot water supply\u003c\/strong\u003e, not just a single point-of-use. A single 13.5kW unit can typically serve a 1–2 bathroom property with sequential (not fully simultaneous) demand. For larger properties or where two outlets run simultaneously at full flow (e.g., shower and bath filling together), two units on separate circuits may be needed — or a larger output is required. For properties currently on gas with a combi boiler, the electric instantaneous heater is the most direct equivalent: same on-demand delivery concept, same multipoint capability, no storage. The key difference is that electrical cost per kWh is higher than gas, so pairing with solar PV (using a diverter) or an off-peak tariff is recommended where possible.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border-bottom: 1px solid #c8e6e3;\"\u003e\n\u003csummary style=\"padding: 13px 16px; cursor: pointer; font-weight: 600; background: #f0faf9;\"\u003eDoes my consumer unit need upgrading?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 11px 16px; font-size: 14px;\"\u003eIt depends on the current state of your consumer unit. The \u003cstrong\u003e13.5kW model requires a 63A MCB\u003c\/strong\u003e on a dedicated circuit — most modern consumer units have ways available, but the busbars and main incomer must be rated for the additional load. If your property has an older 60A or 80A main fuse, adding a 63A circuit may exceed the total available supply — an electrician should assess this before purchase. The \u003cstrong\u003e9kW (45A MCB) and 11kW (50A MCB)\u003c\/strong\u003e are more likely to fit within existing capacity. A Part P registered electrician should always check the consumer unit rating, available ways, and total load before installation. In some cases a \u003cstrong\u003e100A supply upgrade\u003c\/strong\u003e from the DNO may be needed — this is typically free for residential properties below the threshold but takes several weeks to arrange.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border-bottom: 1px solid #c8e6e3;\"\u003e\n\u003csummary style=\"padding: 13px 16px; cursor: pointer; font-weight: 600; background: #fff;\"\u003eCan it be used with solar PV?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 11px 16px; font-size: 14px;\"\u003eYes — the Strom instantaneous water heater is fully compatible with \u003cstrong\u003esolar PV diversion\u003c\/strong\u003e. A solar diverter (such as the myenergi Eddi or an iBoost) monitors the property's generation and import\/export balance, and diverts surplus solar electricity to the water heater's supply when more is being generated than consumed. Because the instantaneous heater only draws power when hot water is being run, it is best used in combination with a solar diverter that can modulate power to the heater — match the heater to the diverter's compatible load range. This is one of the most effective ways to use surplus solar generation in properties without a hot water cylinder — displacing grid electricity consumption with effectively free hot water from daytime generation.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border-bottom: 1px solid #c8e6e3;\"\u003e\n\u003csummary style=\"padding: 13px 16px; cursor: pointer; font-weight: 600; background: #f0faf9;\"\u003eWhat does the fault detection display?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 11px 16px; font-size: 14px;\"\u003eThe touch screen's \u003cstrong\u003eautomatic fault detection system\u003c\/strong\u003e monitors the heater's internal sensors and displays an on-screen error code when a fault condition is detected — rather than the unit simply cutting out with no indication.

The \u003cstrong\u003e14S (28kW, 14 L\/min)\u003c\/strong\u003e is suitable for a 1–2 bathroom property with normal sequential use — one shower or one bath at a time. The \u003cstrong\u003e16S (30kW, 16 L\/min)\u003c\/strong\u003e adds approximately 14% more flow capacity, making it the better choice for properties with \u003cstrong\u003etwo bathrooms used concurrently\u003c\/strong\u003e, a large-volume shower head, or a high-demand kitchen alongside a bathroom. As a practical guide: at a UK winter cold inlet of ~10°C, the 16S delivers approximately 9.5 L\/min at a comfortable 42°C outlet — enough for a good-flow shower and a running basin simultaneously. Both models are physically identical in size and connect identically; the 16S costs marginally more but provides significantly more headroom for peak demand.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border-bottom: 1px solid #c8e6e3;\"\u003e\n\u003csummary style=\"padding: 13px 16px; cursor: pointer; font-weight: 600; background: #fff;\"\u003eDoes this heater work without mains electricity?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 11px 16px; font-size: 14px;\"\u003e\n\u003cstrong\u003eNo\u003c\/strong\u003e — the Biasi Multipoint 16S requires a \u003cstrong\u003e230V mains electrical supply\u003c\/strong\u003e for the microcomputer control system, the DC fan (which provides forced combustion air and post-ventilation), the electronic ignition, and the LCD display. A switchable fused spur must be installed adjacent to the appliance. The unit will not operate during a power cut — no electrical supply means no ignition, no fan, and no combustion. This is a fundamental characteristic of all modern room-sealed fan-flued gas water heaters. For properties with frequent power interruptions, a small UPS may allow continued operation, though this should be discussed with the installer and Biasi before specifying.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border-bottom: 1px solid #c8e6e3;\"\u003e\n\u003csummary style=\"padding: 13px 16px; cursor: pointer; font-weight: 600; background: #f0faf9;\"\u003eWhat flue kit do I need?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 11px 16px; font-size: 14px;\"\u003eThe Biasi Multipoint 16S uses a \u003cstrong\u003e60\/100mm coaxial flue system\u003c\/strong\u003e (type C13 horizontal through-wall or C33 vertical roof terminal).

Have your installer's details ready as Biasi require these to validate the warranty. The guarantee covers manufacturing defects in materials and workmanship when the appliance has been installed and commissioned in accordance with the installation manual and the Benchmark commissioning checklist has been completed. The guarantee does not cover damage caused by installation errors, use of incorrect gas type, inadequate water quality, or failure to maintain the appliance as recommended.

For most fault codes, the recommended first step is: turn off the hot water outlet, press the On\/Off button to switch the unit off, wait a few seconds, switch back on, then reopen the outlet. This clears transient faults (such as ignition failure on first use after a gas interruption, where air in the supply pipe causes several retry cycles). If the fault code persists after two or three attempts, turn off the gas valve and cut the power, and contact your Gas Safe registered engineer.

The \u003cstrong\u003ebare wire heating element\u003c\/strong\u003e used in the DEM 3 Set is inherently resistant to scale build-up and is \u003cstrong\u003eapproved for both hard and soft water areas\u003c\/strong\u003e. There is no anode rod or sacrificial component to inspect or replace.

First, the \u003cstrong\u003eclosed-loop outlet sensor\u003c\/strong\u003e continuously adjusts output to hold the set temperature. Second, the \u003cstrong\u003eautomatic output matching\u003c\/strong\u003e function reduces power if the incoming water temperature rises unexpectedly, preventing the outlet exceeding safe limits.

The DEM 6 Set is rated for shower use \u003cstrong\u003ewhen the cold-water inlet temperature exceeds 20 °C\u003c\/strong\u003e. Below this threshold, the available thermal output may be insufficient to reach comfortable shower temperatures at adequate flow.

(2) \u003cstrong\u003eConnection\u003c\/strong\u003e — DEM 3 Set has a standard 13 A plug; DEM 6 Set requires a hardwired 25 A circuit with 4 mm² cable. (3) \u003cstrong\u003eShower capability\u003c\/strong\u003e — DEM 6 Set can supply a shower at inlet temperatures above 20 °C; DEM 3 Set is rated for washbasin use only.
