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). A flue kit is required for installation and is typically sold separately or as a bundle with the heater. For a standard horizontal through-wall installation, a \u003cstrong\u003e60\/100 horizontal flue kit\u003c\/strong\u003e provides the terminal, coaxial pipe, elbow, seals, and fixings. For longer runs or where bends are required to navigate around obstacles, extension pipes and additional elbows are available from Biasi. Maximum permitted flue lengths vary depending on the number of bends — refer to the installation manual's flue duct length table before finalising the installation position.\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;\"\u003eHow do I register the guarantee and what does it cover?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 11px 16px; font-size: 14px;\"\u003eThe \u003cstrong\u003e2-year parts and labour guarantee\u003c\/strong\u003e must be registered by calling Biasi UK on 01922 714600 within \u003cstrong\u003e30 days of purchase\u003c\/strong\u003e. 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. Annual servicing by a Gas Safe registered engineer is strongly recommended.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border-bottom: 1px solid #c8e6e3;\" open=\"\"\u003e\n\u003csummary style=\"padding: 13px 16px; cursor: pointer; font-weight: 600; background: #f0faf9;\"\u003eCan it be converted from natural gas to LPG (or vice versa)?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 11px 16px; font-size: 14px;\"\u003eYes — the Multipoint 16S can be converted between natural gas (G20) and LPG (G30 butane \/ G31 propane) using the appropriate \u003cstrong\u003eBiasi conversion kit\u003c\/strong\u003e. Gas conversion is a Gas Safe registered engineer task only — it involves changing the burner injectors, adjusting the gas valve pressure settings, and updating the appliance data plate. Do not attempt to operate the unit on a gas type different from its current setting without conversion. Biasi UK supplies conversion kits — contact them at 01922 714600 or via biasi.co.uk.

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.
