Italian-engineered twin tank technology delivers 16% more hot water in a 27cm ultra-slim profile. Eco Evo auto-learning saves up to 14% energy. Dual 1.5kW elements. Anti-legionella. IPX4. 5-year Ariston guarantee. Choose your capacity below.
Two stacked tanks reduce cold water stratification. Cold water enters the lower tank; hot water draws from the upper. Delivers 16% more usable hot water than equivalent single-tank cylinders.
Both the 45L and 80L are just 275mm deep — roughly half the depth of a standard cylinder. Fits in shallow cupboards, voids and spaces where a conventional cylinder won't go.
Integrated auto-learning software memorises your weekly hot water habits and heats water only when you need it. No programming required. Proven to save up to 14% on energy bills.
Maximum electrical draw of 1.5kW at any one time on both models. Compatible with standard domestic circuits and leisure park hook-ups rated at 10A or above. Will not trip standard supplies.
Periodic heating to 65°C on both models prevents legionella bacteria growth. The Anti-Burn System (ABS) manages outlet temperatures to prevent scalding.
Both models are rated IPX4 (splash-protected). Can be installed in bathrooms outside Zones 0 and 1 in accordance with BS 7671 wiring regulations.
