The worlds' futurestarts today

NUOS is the new Ariston heat pump, conceived to be in perfect harmonywith the environment: it is the ecological evolution of the traditionalwater heater, which is replaced with a simple, but at the same time,ingenious, technology.NUOS generates many litres of hot water with little energy.It is able to supply a lot more than that used for its functioning, as itextracts heat directly from air.Technology is finally at the service of nature.

3

Cost-SavingNuos uses a new technology which allows to save up to 270 ¤/year,compared to a traditional electric water heater

Thanks to this, the higher initial cost is paid back in just 4 years.

Energy SavingThe Nuos innovative working principle allows an energy saving up to 70%compared to a traditional electric water heater.

Environment respectNuos heat pump water heater exploits the heat in the air as renewablesource to produce hot water. This modern technology allows a very highenergy saving, which means a deep greenhouse gases emissions

NUOSEcological evolutionis a cost advantage for all

Considering the European Standard withdrawal profiles, the yearly energyconsumption dedicated to the production of DHW is established to be equalto 1.550 kWh/year for a family of 3.The average efficiency of NUOS, estimated by evaluating its efficiency withan average annual temperature of the inlet air equal to 15°C and conside-ring a cost of 0.22/kWh, saves up to 270 per year compared to a traditionalwater heater of equal capacity.A visible and tangible saving on the electricity bill.

AMORTIZATION AND COST SAVINGS

To be equipped with a heat pump means investing in the future.The large energy saving supplied by NUOS means a large economical saving.By comparing the installation of a heat pump respect to a normal electric water heater of equal capacity, itresults that the initial saving can be absorbed in approx. 4 years, after which it turns into saving.

The working principle of NOUS heat pump water heater is really innovativeas it uses the heat from the air as renewable source to produce hot water:it uses a thermodynamic cycle to heat the water contained inside the heaterthrough air sucked from the thermal group.This is the reverse mechanism to that used in refrigerators: refrigerantfluid, through status changes, withdraws the heat contained in the air at lowtemperature and gives it to the water at a higher temperature, in this wayinverting the natural heat flow.NUOS is also equipped with a heat resistance able to start functioningwhen the hot water request is higher or when the environmenttemperature is lower than the minimum functioning temperature (10°C),always guaranteeing maximum comfort in generating DHW.

The NUOS 80-100-120 litres waterheaters have a low energy absorption(~300 W) which allows them to beused together with all other homeappliances without causinginterruptions due to over-absorptionof the domestic electric network.NUOS transform the traditionalelectric water heater in a less impactproduct for your doemstic life

WORKING PRINCIPLE

1 - The refrigerant fluid crosses the evaporator and absorbs the heat supplied by the sucked air.This process ensures that the refrigerant changes phase by evaporating.

2 - The refrigerant gas undergoes, inside the compressor,a pressure increase which entails the temperature rising.

3 - Inside the condenser, the refrigerant gas gives its heat to the water contained inside the heater.This exchange process ensures that the refrigerant passes to liquid state by condensing.

4 - The refrigerant fluid looses further pressure and temperature by crossing the expansion valve,returning to the initial conditions again.

NUOSNatures' breath for regenerating energy

Dehumidifiesthe environmentand allows air changeThe ecological technology applied means further positive effects:the emission of the air exiting the heat pump favours the naturalventilation of the environment and improves air quality by producinga pleasant refreshing and dehumidifying effect.

NUOS is the answer to those making ecological choices and wantingthe best for a greater respect of the environment.Designed with an extraordinary technology, NUOS uses zero impactenergy sources, drastically reducing CO2 emissions. It is amazinghow today it is possible to obtain so much comfort with so little wasteof energy: less than 70% compared to a traditional electric water heater.The world is evolving, evolve with it.

Ecological solutionThe result of this technology is an energy saving of up to 70%compared to a traditional electric water heater.The use of heat pumps favours the reduction of greenhouse gas.In fact, it has been established that the installation of a NUOS 80 heatpump allows a reduction of 480 kg/year of Co₂ linked to the productionprocesses of electric energy. The same effect would be obtained by theabsorption of Co₂ by 40 trees.

The refrigerant fluid used inside the heat pump is very important inestablishing the quality of the product.The one chosen by Ariston, the R134A is not damaging to the ozone layer,the atmospheres' fundamental element for protection against ultravioletradiations, as it has an “ODP” (Ozone Depletion Potential) equal to zero.It does not contain chlorine, damaging for the environment, it is not toxicor flammable, all advantages for both the users' and the installers' safety.The R134A gas, thanks to high thermodynamic features, guarantees highefficiency.

The NUOS heat pump, thanks to its innovative functioning principle, is proven to be very advantageous comparedto a traditional electric water heater of equal capacity.In fact, by working in ECO function NUOS maximises savings whereas, by working in FAST function it maximisesefficiency, consuming continuously less compared to an electric water heater. Below is a table summarising theheating times and electric consumption of the heat pump compared to an electric water heater of equal capacity.The data shown in the table refers to a heating cycle from 10°C to 55°C with an environmental temperatureof 20°C and with the inlet water temperature of 10°C

When the NUOS 80-100-120 litres heat pumps are installed in the home, it is necessary to channel the air outlet inorder to avoid cooling the premises.The wide range of provided accessories allows maximum installation flexibility in any type of environment.It is also possible to channel the inlet air in case warmer premises exist near-by (for example, due to the presenceof other products like boilers, refrigerators, washing machines which produce heat losses) compared to that wherethe product is installed.

The product outlet air must always be channelled to avoid the consequentcooling of the installation premises.When, in fact, the product works with heat pump and it has been installedwithout channelling the outlet air, it cools the premises by 2/4°C.To guarantee functioning with heat pump, the incoming air must have atemperature between 10-37°C. Installations without channelling of theoutlet air can also create recirculation between the outlet air and inletair limiting the correct functioning of the same product.

NUOSHow to install

13

Choose yourown installation

To channel air, piping with a diameter of 125 mm and max. 10 m long can be used.To calculate the length of the pipes, consider every curve and every grid mouth equal to 1 metre long.In case of channelling the outlet and inlet mouths, the total length of the channelsmust be less than 10 m long, with piping with 125 mm diameter.

Calculation example (only for piping with a 125 mm diameter):TOTAL LENGTH [m] = PIPES LENGTH [m] + N° bends + N° MOUTHS TOTAL LENGTH: 10 m = 8 m + 1 + 1

ECOif ECO mode is selected, only theheat pump works, getting themaximum saving.Max reachable temperaturein ECO mode is 55°C

AUTOIn Auto mode heat pump works.Subsequently only if the settemperature is higher than 55°C,the heating element is turned on,in order to have energy savingand the max quantity of hot water.Max temperature in AUTO modeis 65°C

FASTif FAST mode is on, heat pump andheating elements work at the sametime. This mode has to be manuallyselected by the end user every timehe needs hot water in as short aspossible time.Max temperature in FAST modeis 65°C
