color: #333333; line-height: 1.6; background: #ffffff;\"\u003eThe 80-litre tank heats to a maximum of 75°C in normal use (80°C during the antibacterial cycle), and that hot store is blended down at the tap with cold mains water via the built-in mixing valve, so the usable warm-water volume at shower temperature is greater than the tank size alone.

The heater needs a dedicated, RCD-protected electrical circuit, a properly rated and tested earth connection, a wall capable of supporting at least four times the unit’s full water weight, and correctly fitted safety\/non-return valves. \u003cb\u003eFloor-mounted installation is not permitted\u003c\/b\u003e — it’s a wall-hung unit only.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"margin: 0 0 8px 0; border: 1px solid #e3e3e3; border-radius: 6px; overflow: hidden;\"\u003e\n\u003csummary style=\"background: #008377CF; color: #ffffff; padding: 11px 16px; font-weight: 600; cursor: pointer; list-style: none;\"\u003eIs the heating power adjustable?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 12px 16px; color: #333333; line-height: 1.6; background: #ffffff;\"\u003eNo. This model has a single fixed 1500W element — there’s no switch to step the wattage up or down.

The indicator glows orange while it’s still learning your pattern and turns blue once it has enough data. A power cut or disabling Smart mode clears the learned schedule.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"margin: 0 0 8px 0; border: 1px solid #e3e3e3; border-radius: 6px; overflow: hidden;\"\u003e\n\u003csummary style=\"background: #008377CF; color: #ffffff; padding: 11px 16px; font-weight: 600; cursor: pointer; list-style: none;\"\u003eWhat happens in a power cut?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 12px 16px; color: #333333; line-height: 1.6; background: #ffffff;\"\u003eThe heater has a memory function and returns to its previous power and temperature settings once supply is restored.
