The entire system is then manageable via the \u003cstrong\u003eAriston Net app\u003c\/strong\u003e.

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. This eliminates standby heat losses entirely, earning the unit an \u003cstrong\u003eErP energy efficiency class A\u003c\/strong\u003e rating.\u003c\/p\u003e\n    \u003cp\u003eThe \u003cstrong\u003eMulti-Point\u003c\/strong\u003e configuration means the Aures can supply one or several outlets (not simultaneously) from a single unit — suitable for a kitchen sink plus a nearby hand basin, a bathroom wash basin and shower, or multiple hand wash points in a commercial setting. Its compact dimensions (304mm × 220mm × 110mm) make it ideal for installation in narrow utility rooms, under kitchen sinks, in garages, conservatories, en-suites, and annexes where a conventional boiler connection is unavailable or impractical.

However, it is not designed or certified as an electric shower unit and is not rated for a power shower (which would typically require 9.5kW or more as a dedicated shower-only device).

As a general principle for coaxial flue systems, a 45° bend is typically equivalent to approximately \u003cstrong\u003e0.5–1 metre of straight pipe\u003c\/strong\u003e in terms of resistance — significantly less than a 90° elbow (typically equivalent to ~1–2m). The maximum permissible total equivalent flue length for the Next Evo X varies depending on whether the configuration is horizontal or vertical — always refer to the installation manual and calculate the total equivalent length before finalising the flue route. Exceeding the maximum equivalent length can impair combustion and compromise safety.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border-bottom:1px solid #c8e6e3;\"\u003e\u003csummary style=\"padding:13px 16px;cursor:pointer;font-weight:600;background:#fff;\"\u003eCan I use just one of the two elbows and keep the other as a spare?\u003c\/summary\u003e\u003cdiv style=\"padding:11px 16px;font-size:14px;\"\u003eYes — both elbows in the pack are identical, so if your installation only requires a single 45° direction change you can use one elbow and retain the second for future modifications or service. However, most installations that require a 45° offset benefit from using both elbows as a \u003cstrong\u003esymmetrical offset pair\u003c\/strong\u003e — the first bending the flue off-axis, an extension carrying it across the obstruction, and the second returning it to the original axis.

The \u003cstrong\u003e3318004 is specifically for the Next Evo X water heater range\u003c\/strong\u003e (the SE system). Ariston boilers (E-Combi, E-System, Clas, Alteas, etc.) use different flue systems and part numbers even when the physical pipe diameter appears similar. Always match the flue accessory MPN to the specific appliance model and the installation manual's approved accessories list. Using a flue accessory from the wrong range can result in incorrect sealing, air leakage into the flue gas stream, or flue gas leakage into the room.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary style=\"padding:13px 16px;cursor:pointer;font-weight:600;background:#fff;\"\u003eDo I need any additional seals or fixings when fitting these elbows?\u003c\/summary\u003e\u003cdiv style=\"padding:11px 16px;font-size:14px;\"\u003eThe coaxial elbow joints in the Ariston SE system use \u003cstrong\u003eintegral push-fit or twist-lock connections with built-in gaskets\u003c\/strong\u003e — no additional PTFE tape, mastic, or separate seals are required at the elbow joints themselves. The gaskets are pre-fitted to the pipe sockets. However, if the elbows are fitted within a building void or concealed space, the installer should confirm all joints are correctly seated and locked before concealing the flue run — access for future inspection should be maintained where possible.

Each 90° elbow (3318075) deducts from these totals — refer to the installation manual for the specific deduction per fitting. If the installation requires more than 7 metres, upgrading to the \u003cstrong\u003eØ80\/125 coaxial system supports up to 24 metres\u003c\/strong\u003e on the 30 kW model, though this requires a different starter and larger roof penetration.\u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails style=\"border:1px solid #ddd;border-top:none;padding:0;\"\u003e\n    \u003csummary style=\"padding:14px 16px;cursor:pointer;font-weight:600;background:#f9f9f9;\"\u003eShould I choose the 24 kW or 30 kW for my lodge or static caravan?\u003c\/summary\u003e\n    \u003cdiv style=\"padding:14px 16px;border-top:1px solid #eee;\"\u003eThe key differentiator is \u003cstrong\u003ehot water demand\u003c\/strong\u003e.
