Ariston NUOS SPLIT standing


The heat pump water heaters Ariston NUOS SPLIT standing provide domestic hot water by a heat pump that heats a kettle, with a split type or with an external drive system.

The heat pump mainly uses the outside air as a renewable energy source to achieve maximum energy efficiency and high energy savings.

Ariston NUOS SPLIT stand is available in 150, 200 and 300 liters of volume of the kettle and the main features are:

  • eligible outside air temperatures from -5 to 42 ° C
  • Ecological gas R134A to heat water up to 62 ° C
  • Low noise fan
  • Additional electric heater dual power
  • LCD display

Operating mode: green, car, boost, boost 2

The operation of the water heater heat pump Ariston NUOS SPLIT standing is based on the thermodynamic cycle of the heat pumps which allows to heat the hot water stored in the tank through the energy present in the outdoor air, sucked by the ducted pipe or directly from the local.

The ecological gas R134A, using status changes due to compression and expansion cycles, draws its energy from the outdoor air and transfers it to the sanitary water stored in the tank.

The electrical energy required by the water heater in the heat pump is only that required to operate the fan and one for powering the compressor (which allows the movement of gas R134A). In the case of the electric heaters are activated necessity which ensure domestic hot water production.

The main features are:

  • Ecological gas R134A order to heat the sanitary water up to 62 ° C only with the use of the heat pump
  • eligible outside air temperatures from -5 to 42 ° C
  • COP EN 16147 = 2,41 150; 2.60 mod. 200; 2.57 mod. 300
  • Electrical power consumption mean = 680 W
  • Product with dimensions and sanitary hot water capacity suitable for a replacement of an existing traditional electric kettle
  • low weight thanks to the outdoor unit = 60 kg I.U. mod. 150; 65 kg I.U. mod. 200; 87 kg I.U. mod. 300
  • Sound-optimized through the outdoor unit – 15 db (A) I.U.
  • Kettle enameled steel with active anode and magnesium anode
  • Exchanger wound on the outside of the tank (not immersed in healthcare)
  • immersion heater dual power 1500 W + 1000 W
  • LCD display

Operation: green, car, boost, boost 2 and possibility of hourly programming and sampling and legionella function
