It is available in two power ratings: \u003cstrong\u003e8.5kW (SPAVENA8)\u003c\/strong\u003e and \u003cstrong\u003e9.5kW (SPAVENA9)\u003c\/strong\u003e.

Hot water is available the moment you turn the dial and continues as long as you need it — completely independent of the boiler, hot water cylinder or any other draw-off point in the home. It keeps working even when the boiler is off, being serviced, or has broken down.\u003c\/p\u003e\n\n  \u003cp style=\"font-size: 15px;\"\u003e\u003cstrong style=\"color: #008377;\"\u003eSwivel-Fit™ — 180° Reversible Water Inlet\u003c\/strong\u003e\u003cbr\u003e\n  Triton's Swivel-Fit allows the water inlet to be rotated 180° before fixing, accepting the incoming supply from either the left or the right-hand side without any modification to the unit. On retrofit jobs where the existing pipework direction is fixed, this eliminates the need to reroute pipework just to match the shower's inlet position.\u003c\/p\u003e\n\n  \u003cp style=\"font-size: 15px;\"\u003e\u003cstrong style=\"color: #008377;\"\u003eLeft \u0026amp; Right Cable Entry Points\u003c\/strong\u003e\u003cbr\u003e\n  The Avena accepts mains cable entry from both the left and right sides of the unit. Combined with Swivel-Fit, both the plumber and electrician can use the most practical entry route independently — an important feature that keeps retrofit installations clean and minimises unnecessary surface wiring or chasing.\u003c\/p\u003e\n\n  \u003cp style=\"font-size: 15px;\"\u003e\u003cstrong style=\"color: #008377;\"\u003eSeparate Power and Temperature Controls\u003c\/strong\u003e\u003cbr\u003e\n  Two independent dials handle power and temperature separately. Users can set their preferred temperature once and then simply turn the power on and off without losing that setting. This is both more intuitive and more energy-efficient than a combined single-dial control.\u003c\/p\u003e\n\n  \u003cp style=\"font-size: 15px;\"\u003e\u003cstrong style=\"color: #008377;\"\u003eStabilised Temperature Control\u003c\/strong\u003e\u003cbr\u003e\n  Stabilised temperature technology reduces variation in water temperature caused by fluctuations in mains pressure or incoming water temperature throughout the shower. The result is a more consistent, comfortable experience compared to non-stabilised electric showers.\u003c\/p\u003e\n\n  \u003cp style=\"font-size: 15px;\"\u003e\u003cstrong style=\"color: #008377;\"\u003eA Energy Rating\u003c\/strong\u003e\u003cbr\u003e\n  The Avena holds an A energy efficiency rating. As an on-demand system, it heats only the water actually being used and has no standby losses — making it inherently efficient versus stored hot water systems regardless of the kW rating selected.\u003c\/p\u003e\n\n  \u003cp style=\"font-size: 15px;\"\u003e\u003cstrong style=\"color: #008377;\"\u003eWhite\/Chrome Shower Kit Included\u003c\/strong\u003e\u003cbr\u003e\n  Both variants come with a complete matching shower kit: riser rail, adjustable head holder, 70mm rub-clean single spray shower head and a 1.25m Duraflow anti-twist hose — all in white and chrome.

A dedicated, permanently connected double-pole circuit from the consumer unit is required, wired in accordance with BS 7671 (IET Wiring Regulations). The circuit must be sized to match the selected variant:\n  \u003c\/p\u003e\n  \u003cul style=\"font-size: 15px; padding-left: 20px;\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e8.5kW (SPAVENA8):\u003c\/strong\u003e typically 6mm² cable, 40A MCB — confirm with your electrician based on cable run length and installation method.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003e9.5kW (SPAVENA9):\u003c\/strong\u003e typically 10mm² cable, 45–50A MCB — confirm with your electrician.

It is completely independent of your boiler, cylinder or any other hot water source — and continues working even if the boiler is off or broken down.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv style=\"margin-bottom: 16px;\"\u003e\n    \u003cp style=\"font-weight: bold; color: #008377; margin-bottom: 4px;\"\u003eHow do I know which power rating to choose?\u003c\/p\u003e\n    \u003cp style=\"margin: 0; font-size: 14px;\"\u003eCheck the MCB in your consumer unit that is labelled for your shower circuit. If it is a 40A breaker, your existing supply is rated for the 8.5kW (SPAVENA8) and you can replace it directly. If it is 45A or higher, or if you are installing from scratch with new wiring, choose the 9.5kW (SPAVENA9) for the best all-year performance. If you're unsure, ask your electrician before ordering.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv style=\"margin-bottom: 16px;\"\u003e\n    \u003cp style=\"font-weight: bold; color: #008377; margin-bottom: 4px;\"\u003eWhat water pressure do I need?\u003c\/p\u003e\n    \u003cp style=\"margin: 0; font-size: 14px;\"\u003eA minimum static pressure of 1 bar is required (0.4 bar minimum operating pressure). Most UK mains-fed properties exceed this comfortably. The unit handles up to 10 bar static \/ 5 bar operating pressure. If in doubt, check with a pressure gauge at the nearest cold tap.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv style=\"margin-bottom: 16px;\"\u003e\n    \u003cp style=\"font-weight: bold; color: #008377; margin-bottom: 4px;\"\u003eWill the Avena fit in place of my existing electric shower?\u003c\/p\u003e\n    \u003cp style=\"margin: 0; font-size: 14px;\"\u003eIn most cases, yes. Both variants share the same 308 × 208 × 108mm footprint, and the Swivel-Fit inlet with dual cable entry means the Avena suits most existing pipe and cable configurations without rerouting. The main consideration is matching the kW rating to your existing circuit — or planning a supply upgrade if you are choosing a higher-rated variant.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv style=\"margin-bottom: 16px;\"\u003e\n    \u003cp style=\"font-weight: bold; color: #008377; margin-bottom: 4px;\"\u003eDoes flow rate change in winter?\u003c\/p\u003e\n    \u003cp style=\"margin: 0; font-size: 14px;\"\u003eYes, slightly. Because the element must work harder to heat colder incoming mains water in winter, flow rate at a given temperature setting will be marginally lower than in summer. This is normal for all instant electric showers. The 9.5kW variant has more thermal headroom, so the seasonal variation is less noticeable.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv style=\"margin-bottom: 16px;\"\u003e\n    \u003cp style=\"font-weight: bold; color: #008377; margin-bottom: 4px;\"\u003eDoes this shower work with a gravity-fed (cistern) system?\u003c\/p\u003e\n    \u003cp style=\"margin: 0; font-size: 14px;\"\u003eOnly if the cistern is high enough to provide at least 1 bar static pressure — approximately 10 metres of head. Most domestic gravity-fed systems fall below this threshold.
