1. Advantages of the Ariston Nuos Primo HC Water Heater
In today's market landscape, there is an increasing inclination towards selecting eco-friendly products and sustainable energy solutions. The Ariston Nuos Primo HC water heater is currently a favored choice due to its prominent advantages, including:
1.1. Beautiful Design Suitable for Outdoor Installation
With a sleek design inspired by Italian aesthetics and European standards, the Ariston Nuos Primo HC water heater features a striking monolithic design in elegant white, coupled with an impressive V-shaped control panel resembling a contented smile. This design not only seamlessly integrates with neutral wall colors but also complements various other furnishings in your home, ensuring hassle-free installation in any space.
While it's recommended to install indoors in spaces like bathrooms, kitchens, or laundry rooms, if indoor space is limited, you can still install the Ariston Nuos Primo HC heat pump water heater in well-ventilated outdoor areas with shelter such as corridors, balconies, or under eaves.
*Note: The air temperature range for heat pumps to operate fluctuates from -5°C to 42°C.

1.2. Large Capacity, Suitable for Various Users
The Nuos Primo HC heat pump water heater series by Ariston currently offers three models in the market: Nuos Primo HC 200, Nuos Primo HC 240, and Nuos Primo HC 240 SYS, with tank capacities ranging from 202 liters to 244 liters. With this capacity, Nuos Primo HC is an ideal choice for large families (around 6 or more users with high demand) or multi-story houses with multiple bathrooms, requiring ample hot water usage such as swimming pools, restaurants, hotels, hospitals, etc.
1.3. Highly Energy Efficient
The Ariston Nuos Primo HC operates on the principle of extracting heat and air from the surrounding environment, compressing it, and raising the temperature of water in the tank through heat transfer. The heat regeneration cycle is continuously repeated as the refrigerant gas R134A returns to the compressor, gets compressed again, and generates new heat to sustain the heat transfer process.
When electricity is needed, the Ariston Nuos Primo HC only consumes very little power, approximately 500W, yet it produces 3-4 times the amount of heat, heating water continuously in just 6.19 hours to 7.59 hours, thus saving a significant amount of energy. Depending on the model, the annual electricity consumption ranges from 912kWh to 1,470kWh.
1.4. Versatile Modes to Meet Various User Needs
The Ariston Nuos Primo HC heat pump water heater is equipped with various modes such as:
- The “Silent” mode allows the machine to operate quietly, reducing noise in the installation room.
- The “Green” mode optimizes power consumption and provides hot water up to 62°C.
- The “Boost” mode ensures the fastest hot water supply.
- In addition, the machine also features a weekly scheduling function, allowing you to proactively set the time and heat water according to your desired schedule, thereby saving a lot of adjustment time.
- And many other convenient functions such as Auto mode or Antilegionella antibacterial function,...

1.5. Rapid Heating, Maintains Stable Warm Temperature
Thanks to improvements such as the design of the coil wrapped around the tank and the inclusion of dual power Steatite heating elements, the Ariston Nuos Primo HC can heat water twice as fast as conventional heat pump water heaters.
The water temperature is maintained at a stable warmth of about 42°C. When you need to adjust the water temperature to your preference, whether hotter or cooler, you can choose suitable custom modes on the LED control screen.
1.6. Remote Management via Smart Connectivity
In addition to being equipped with various modern and versatile technologies, the Nuos Primo HC heat pump water heater also allows you to manage settings remotely via the Ariston Net app. With this, you can adjust all temperature settings on the Nuos Primo HC remotely from your smartphone with the installed app.
Furthermore, the latest Ariston Nuos Primo HC 240 SYS model is also equipped with additional integration with solar energy systems or boilers to further save energy.
