As a practical guide for UK mains temperatures (10–15°C inlet in winter): the \u003cstrong\u003e9kW\u003c\/strong\u003e delivers a comfortable 37°C at approximately 3.5 L\/min — sufficient for a single shower or basin. The \u003cstrong\u003e11kW\u003c\/strong\u003e raises this to approximately 4–5 L\/min at the same temperature — suitable for a standard shower head or one basin plus one outlet. The \u003cstrong\u003e13.5kW\u003c\/strong\u003e provides approximately 5–6 L\/min at 37°C — the best choice for higher-flow showers, multiple simultaneous outlets, or properties where the incoming cold water is particularly cold (e.g., rural mains or winter loft installations).

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.
