R290 domestic wall-mounted high-efficiency heat pump water heater
Domestic hot water ideal for condominiums and single-family homes

A+ heat pump water heater, 150 g R290 refrigerant

The R290 wall mounted heat pump water heater is a comprehensive solution to your family’s needs and known for its A+ energy efficiency rating. It features innovative technology that minimizes energy consumption, bringing affordable, energy-efficient and environmentally friendly heating solutions to homes. It saves more energy, uses fewer resources and heats more efficiently. Notably, it uses only 150 grams of highly efficient R290 refrigerant, which has a very low global warming potential, and achieves a satisfactory COP value of 4.32.

Wall mounting saves floor space

The wall-mounted heat pump water heater radically changes the way we have always thought about water heaters. The water heater has been cleverly designed to provide efficient and reliable hot water wherever it is needed. One of the outstanding features of this water heater is its versatility. Not only is it small and compact, but its convenient wall-mounted design makes it easy to install wherever hot water is needed.

Maximum outlet water temperature up to 75°C

The Nostro range of R290 wall mounted heat pump water heaters is characterized by a high water temperature output of up to 75ºC. This high temperature output is guaranteed to provide hot water at the desired temperature for a wide range of domestic applications. With advanced technology and a precise temperature control system, it not only maximizes energy efficiency, but also provides users with exceptional comfort and convenience. When using the water heater, it’s easy to say goodbye to cold water and enjoy the luxury of having hot water on demand. Whether it’s for bathing, washing or any other domestic water need, it’s the perfect solution to bring warmth and convenience to your home.

High quality, durability and multi-protection

Durability and quality

The unique enameled tank lining provides unrivaled corrosion protection against the harmful effects of water. In addition, enameled tanks have the ability to prevent bacteria, mold and other fungi from growing on the surface of the tank liner, thus enhancing the protection of the product. This is because the enameled tank lining and its protective features are stable and long-lasting throughout the life of our water heaters.

Overheating protection

Our water heaters are carefully equipped with an excellent overheating protection system, which also has an independent thermal disconnect mechanism. This unique mechanism ensures your safety in all aspects of use, while providing you with unparalleled comfort.

Dry heating protection

When the water level in the tank is below the normal range of conditions, our water heater will quickly and automatically cut off the power supply, thus effectively preventing overheating, and thus strongly protect the user’s personal safety and equipment operation safety.

Humidity protection

The rigorous IPX4 humidity protection test has been passed by Nostro water heaters, ensuring their dependability and longevity even in moist and humid conditions.

Leakage protection

In the event of a leak, our water heaters cut off the power in an unimaginably fast 0.01 seconds. This vital safety measure not only provides greater reliability for the water heater, but also prevents other appliances, such as refrigerators, from facing potential problems, thus ensuring the safety of the entire electrical environment.

Two capacities to choose from

We offers two distinctive models, designed to meet the needs of families of all sizes. Available in 80L and 100L sizes, this ensures that customers can choose the ideal option for their specific requirements. 80 liters is ideal for smaller households or those with relatively low hot water needs, and its compact size makes it a good choice for those with limited space. The 100-liter model is more suitable for larger families or those with high hot water usage. Given its large capacity, it ensures that sufficient hot water is available for extended periods of activity, and we offers both sizes with the main aim of providing customers with excellent flexibility and customization. Families can choose the right model for their specific requirements, effectively optimizing comfort and energy efficiency.

More efficient, Hi-COP

In the process of heating hot water, the Nostro wall-mounted R290 heat pump water heater automatically calculates and analyzes the current operating conditions and then flexibly adjusts the input power to achieve the optimal COP value. Under the specific conditions of (EN16147) 20-15°C, it can successfully achieve a COP value of up to 2.787. In the long run, it can significantly help to reduce energy consumption and save users money on energy costs. With its outstanding energy efficiency, this water heater stands out from many other ordinary water heaters on the market.
