Ariston Nuos PLUS Wi-Fi 250 SYS heat pump water heater - 250 liters A+ with coil

Ariston Nuos Plus Wi-Fi 250 SYS monobloc heat pump water heater - 250 liters with coil

NUOS PLUS WI-FI is the new Ariston air-water heat pump water heater dedicated to installations where it is not possible to use the water heater with a separate Outdoor Unit. The heat pump revolution is rendered with new standards of efficiency thanks to the use of the heat in the air as a source of renewable energy to obtain greater comfort and high energy savings, reducing electricity consumption to a minimum.

The NUOS PLUS WI-FI 250 SYS model has a coil and probe holder for solar, boiler or biomass integration.

Completely revisited design with a simple and modern line that fits perfectly into different types of environments. The NUOS PLUS WI-FI model differs from all the other models due to its predisposition for integration with a solar thermal system .

GUARANTEED SAVINGS AND HIGH COMFORT

The Ariston NUOS PLUS WI-FI heat pump water heater is of the air-water type, produces domestic hot water with the lowest heating time in its category and very low energy consumption. The monobloc model is composed of a single element which contains all the components including the fan, the evaporator, the rotary compressor, the expansion valve, the four-way valve and the boiler. If housed in a technical room, the water heater can draw in and expel the air in the same room in which it is installed as long as the volume is not less than 30 m³, but NUOS PLUS WI-FI also allows you to channel the air both in entrance and exit, an indispensable solution if it is installed in an environment other than a dedicated room.

The constitution of the monoblock type allows you to have an "all inside" heat pump water heater for which you do not need an external unit, a solution that solves many needs related to condominium or architectural constraints; NUOS PLUS WI-FI can be installed resting on the floor and has small dimensions . The monoblock water heaters also allow you to use the cold and dehumidified air to cool the internal environments using the appropriate ducts. Although the compressor is in the monoblock, the particular insulation and the reduced vibrations of the compressor make it very silent ; installation is particularly easy since the masonry works are limited to the construction of the condensate drain and any air ducting and the first start-up does not require the technician to have refrigeration skills. Maintenance is very easy as it is limited to cleaning the evaporator which is located in an easily accessible position in the upper part of the monoblock.

The NUOS PLUS WI-FI water heater has operating capacities with air temperatures ranging from -10°C to 42°C, it uses R134A ecological GAS which allows water temperatures to be reached up to 62°C in heat pump mode. The condenser is not immersed in the water but is wrapped around the boiler which is in titanium enamelled steel and equipped with a particular thick insulation, it is equipped with a double power electric resistance in steatite (1500 W + 1000 W), active anode and magnesium anode. Sanitary recycling. It is controlled through the control panel with LCD display , completely renovated aesthetically, located on the Internal Unit which constantly communicates the operating parameters and the set functions, among which the most important are the Green Function which optimizes energy saving, the Fast Function (permanent boost ) which allows heating times to be reduced using both the heat pump and resistance integration, the I-Memory Mode which offers the best ratio between comfort and savings, the Holiday Function which suspends operation for the number of days of absence from the home, the Silent Function reduces the already minimal noise levels, the Anti-Legionella Function which independently disinfects, if necessary, the tank by automatically killing all bacteria.

Energy consumption is among the lowest in the category; the article is placed in Energy Class A + and allows a considerable energy saving with cost reductions that reach 70% less than a normal electric water heater of equal power. Furthermore, the possibility of optimizing operation with the boiler or for heating only, the integrated Photovoltaic Function , the External Load Activation Function make it the most versatile and efficient item in the NUOS range.

TECHNOLOGICAL EXCELLENCE

The NUOS PLUS WI-FI by Ariston has Wi-Fi as standard which allows remote management via APP; System options with BridgeNET bus compatibility for integration into complex systems.

If you have a photovoltaic system, with the PHOTOVOLTAIC FUNCTION   it is possible to set the product to raise the water temperature set point to make the most of the excess solar energy.

ANTIFREEZE : this system prevents the condensation water from freezing so that Nuos can operate in heat pump mode even with air at -5°C; when the product is powered and there is no request for hot water, if the temperature of the water in the tank drops below 5°C, the resistance (1000 W) will automatically be activated to heat the water up to 16°C.

DEFROST : the defrost is activated when the heat pump has been working for at least 20 minutes, the detected air temperature is below 15°C and the evaporator temperature decreases rapidly.

AIR FILTER : slows down the clogging of the heat exchange coil and can be removed from above, facilitating maintenance.

AIR CIRCUIT : patented architecture for the reduction of noise and heat loss.
