HEAT PUMP CATALOGUE
The worlds' future
starts today
NUOS is the new Ariston heat pump, conceived to be in perfect harmony
with the environment: it is the ecological evolution of the traditional
water 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 it
extracts heat directly from air.
Technology is finally at the service of nature.

Considering the European Standard withdrawal profiles, the yearly energy
consumption dedicated to the production of DHW is established to be equal
to 1.550 kWh/year for a family of 3.
The average efficiency of NUOS, estimated by evaluating its efficiency with
an average annual temperature of the inlet air equal to 15°C and considering a cost of 0.22/kWh, saves up to 270 per year compared to a traditional
water 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, it
results that the initial saving can be absorbed in approx. 4 years, after which it turns into saving.

6
The working principle of NOUS heat pump water heater is really innovative
as 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 heater
through air sucked from the thermal group.
This is the reverse mechanism to that used in refrigerators: refrigerant
fluid, through status changes, withdraws the heat contained in the air at low
temperature and gives it to the water at a higher temperature, in this way
inverting the natural heat flow.
NUOS is also equipped with a heat resistance able to start functioning
when the hot water request is higher or when the environment
temperature is lower than the minimum functioning temperature (10°C),
always guaranteeing maximum comfort in generating DHW.
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.

The NUOS 80-100-120 litres water

(~300 W) which allows them to be
used together with all other home
appliances without causing
interruptions due to over-absorption
of the domestic electric network.

HIGH
EFFICIENCY
NUOS is the answer to those making ecological choices and wanting
the best for a greater respect of the environment.
Designed with an extraordinary technology, NUOS uses zero impact
energy sources, drastically reducing CO2 emissions. It is amazing
how today it is possible to obtain so much comfort with so little waste
of energy: less than 70% compared to a traditional electric water heater.
The world is evolving, evolve with it.
Ecological solution
The 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 heat
pump allows a reduction of 480 kg/year of Co₂ linked to the production
processes of electric energy. The same effect would be obtained by the
absorption of Co₂ by 40 trees.
Dehumidifies
the environment
and allows air change
The ecological technology applied means further positive effects:
the emission of the air exiting the heat pump favours the natural
ventilation of the environment and improves air quality by producing
a pleasant refreshing and dehumidifying effect.
8
The refrigerant fluid used inside the heat pump is very important in
establishing 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 ultraviolet
radiations, as it has an “ODP” (Ozone Depletion Potential) equal to zero.
It does not contain chlorine, damaging for the environment, it is not toxic
or flammable, all advantages for both the users' and the installers' safety.
The R134A gas, thanks to high thermodynamic features, guarantees high
efficiency.
9
High efficiency
The NUOS heat pump, thanks to its innovative functioning principle, is proven to be very advantageous compared
to 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 maximises
efficiency, consuming continuously less compared to an electric water heater. Below is a table summarising the
heating 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 temperature
of 20°C and with the inlet water temperature of 10°C

How to install
When the NUOS 80-100-120 litres heat pumps are installed in the home, it is necessary to channel the air outlet in
order 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 presence
of other products like boilers, refrigerators, washing machines which produce heat losses) compared to that where
the product is installed.
Why installby
channelling the
outlet air
The product outlet air must always be channelled to avoid the consequent
cooling of the installation premises.
When, in fact, the product works with heat pump and it has been installed
without channelling the outlet air, it cools the premises by 2/4°C.
To guarantee functioning with heat pump, the incoming air must have a
temperature between 10-37°C. Installations without channelling of the
outlet air can also create recirculation between the outlet air and inlet
air limiting the correct functioning of the same product.

Code:3208052
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 channels
must 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
