Ariston Heat Pump Water Heater

Efficient Hot Water, Built for the Future

Heat pump water heaters are one of the most efficient ways to heat water at home, and the Ariston NUOS makes the upgrade easy to live with. Instead of generating heat directly like a conventional electric water heater, it pulls heat from the surrounding air and transfers it into the water — using up to 70% less energy while providing reliable hot water for everyday life.

Available in 50-, 65-, and 80-gallon sizes, the Ariston NUOS is a strong choice for homeowners looking to lower energy use, move away from fossil fuels, or make progress toward whole-home electrification.

Smart Comfort, Lower Energy Use

The NUOS includes multiple operating modes so you can balance efficiency and recovery speed based on your household’s needs. Its I-Memory technology learns your hot-water habits over time, helping make sure hot water is ready when you typically need it while conserving energy when you don’t.

Integrated Wi-Fi and app controls also let you monitor and adjust the system remotely.
