250 Liters - Heat Pump - Underfloor - Monobloc - With predisposition for photovoltaic integration, boiler, solar thermal and biomass
Cod. 3079055
Water heater Air-water heat pump with solar coil Ariston NUOS PLUS 250 TWIN SYS - 250 liters .
NUOS PLUS 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 absolutely innovative operating principle ensures that the heat pump subtracts the heat already present in the air to transfer it to the sanitary water thanks to the thermodynamic cycle. Electricity consumption is reduced to a minimum. Excellent aesthetic appearance with a pleasant and modern line that fits well into any environment. The PLUS TWIN SYS model differs from all the other models for its predisposition to connect other energy or power sources such as a photovoltaic system , a boiler , a solar thermal system and a biomass system.
GUARANTEED SAVINGS AND HIGH COMFORT
The Ariston NUOS PLUS heat pump water heater is of the air-water type, it produces domestic hot water with short heating times and very low energy consumption. The monobloc model consists of a single element that encloses all the components including the fan, the evaporator, the rotary compressor, the expansion valve, the four-way valve and the boiler. If it is housed in a technical room, the water heater can take and expel the air in the same room where it is installed as long as the cubic volume is not less than 30 cubic meters. but NUOS PLUS also allows you to channel both incoming and outgoing air, an indispensable solution if it is installed in an environment other than a dedicated room.
The constitution of the monobloc type allows to have an “all-in” heat pump water heater for which an Outdoor Unit is not required, a solution that solves many needs related to condominium or architectural constraints; it can be installed resting on the floor and has reduced dimensions . The monobloc water heaters also allow the use of cold and dehumidified air to cool the internal environments using the appropriate ducts. Although the compressor is in the monobloc, the particular insulation and reduced vibrations of the compressor make it very silent ; the installation is particularly easy since the building works are limited to the realization of the condensate drain and the possible air ducting and the first start-up does not require the technician to have the skills of a refrigeration engineer. 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 monobloc.
The NUOS PLUS water heater has operating capabilities with air temperatures ranging from -7 ° C up to 42 ° C, it uses R134A GAS which allows to produce hot water up to 62 ° C. in heat pump and up to 75 ° C with electric resistance. The condenser is not immersed in water but wrapped around the boiler which is made of titanium enamelled steel and equipped with a particular insulation with an important thickness, is equipped with an integrative electrical resistance, an active anode and a magnesium anode, two coils and probe holders for integration and sanitary recirculation systems. It is controlled via the control panel with LCD display placed on the Indoor 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 Boost and Boost2 Function which allow you to reduce heating times by using both the heat pump and the electric resistance, the Auto Mode which offers the best ratio between comfort and savings, the Hourly Programming of Withdrawals thanks to which it is possible to customize two time bands for greater use of hot water , the Voyage Function which suspends operation for the number of days of absence from the home programmed, the Silent Function reduces the already minimum noise levels, the Anti- Legionella Function which if necessary autonomously disinfects the tank by automatically killing all bacteria.
Energy consumption is among the lowest in its category, the item is in Energy Class A. and allows significant energy savings with cost reductions that reach 70% less than a normal electric water heater of the same 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.
