Ariston Nuos Plus 250 SYS heat pump with Wi-Fi

Discover aerothermal energy with Nuos Plus:
The NUOS heat pump is a sustainable and innovative solution in hot water for the home. NUOS uses a natural and inexhaustible source of energy: the heat of the air. Thanks to this technology, heat is extracted from the air to heat the water, spending a minimum amount of energy, only that necessary for the circulation of air and refrigerant.

The water in the accumulator is heated through a thermodynamic cycle, taking advantage of the heat of the air sucked in by the thermal unit. This process is achieved through changes of state and cycles of compression and expansion to which the R134a refrigerant gas is subjected.

The heat contained in the air at a lower temperature is transferred to the accumulated water at a higher temperature, thus reversing the natural flow of heat. This cycle is the reverse of the one used in a refrigerator.

Thanks to NUOS technology, 75% of the heat generated is free without the need to give up the usual comfort.
