NUOS EVO A+ 150 WH
The Ariston NUOS EVO A+ 150 WH is a premium, wall‑hung monobloc heat pump water heater designed for compact indoor installations. With a 150 litre capacity and energy class A+, it cleverly extracts ambient air heat (operating from –5 °C up to +42 °C) to efficiently heat water to up to 62 °C via the heat pump, or a maximum of 75 °C using the integrated electric element. Featuring a titanium‑enameled steel tank wrapped in the condenser, it delivers silent operation (~50 dB(A)), multiple modes (green, boost, auto, anti‑legionella, holiday), as well as integrated anodes (ProTech + magnesium), LCD display, and minimal energy consumption (~250 W), saving up to 70 % vs. standard electric models
