R290 Air to Water Heat Pump

R290 monobloc heat pump platform for floor heating, radiators, fan coils and domestic hot water applications.

One Heat Pump Platform for Heating, Cooling and Hot Water

The YUJU R290 air-to-water heat pump transfers energy from outdoor air into a hydronic system, providing a flexible solution for year-round indoor climate control.

The system can be integrated with:

• Underfloor heating systems
• Radiators
• Fan coil units
• Domestic hot water tanks
• Hydronic modules
• Solar-assisted systems

This makes the platform suitable for new residential construction, renovation projects and replacement of conventional fossil-fuel heating systems.

R290 EVI Heat Pump Range

The R290 EVI monobloc series covers multiple heating capacities and electrical configurations for different European residential and light-commercial projects.

High-Temperature Water up to 85°C

The R290 EVI platform is designed for applications requiring higher water temperatures than conventional low-temperature heat pumps.

High water temperature capability makes the system suitable not only for floor heating but also for radiator systems and retrofit projects where higher supply-water temperatures may be required.

One R290 hydronic platform can support floor heating, radiators, fan coils and domestic hot water throughout the year.

EVI Technology for Low-Ambient Heating

Enhanced Vapor Injection (EVI) technology extends the operating range of the heat pump and improves heating capability under low outdoor temperatures.

This combination is particularly suitable for European regions requiring reliable winter heating and compatibility with both low-temperature and high-temperature hydronic terminals.

High Seasonal Energy Efficiency

The R290 EVI series is designed for high seasonal heating efficiency under European ErP operating conditions.

The inverter compressor and variable-speed control system continuously adjust capacity according to actual heating or cooling demand, helping reduce unnecessary energy consumption during partial-load operation.

Example Performance – 12 kW R290 EVI Model

Performance values are representative of the referenced 12 kW R290 EVI platform under specified test conditions. Final performance depends on model selection and operating conditions.

Smart Hydronic Control

The R290 heat pump system can be integrated with intelligent hydronic control functions to improve comfort and system efficiency.

• Two-zone water temperature control
• Weather-dependent water temperature control
• Smart Grid operating functions
• Modbus communication capability
• Wi-Fi connectivity
• Silent operating modes
• Domestic hot water control
• External auxiliary heat-source integration

Smart hydronic controls help coordinate water temperature, heating zones, domestic hot water and energy-management strategies.

Cascade up to 8 Heat Pumps

For larger residential and commercial applications, one controller can manage multiple R290 heat pumps in cascade.

Cascade operation provides greater design flexibility for villas, apartment buildings, hotels, commercial buildings and other projects requiring higher total heating capacity.
