6kW–12kW R290 Air-to-Water Heat Pump | High Temp 75°C | Low GWP Heating

Eco-Friendly R290 Refrigerant for Sustainable Heating

This heat pump uses R290 refrigerant, a natural hydrocarbon with an ultra-low Global Warming Potential (GWP) of just 3. As a next-generation refrigerant, R290 not only meets the latest European F-Gas regulations but also supports long-term sustainability goals. Its excellent thermodynamic properties allow for higher efficiency and stable performance even in extreme conditions. By choosing R290, you're reducing environmental impact without compromising on heating performance.

Outstanding Energy Efficiency

By combining free ambient air energy with a small amount of electricity, this R290 heat pump delivers up to 4 units of heat output for every 1 unit of power consumed. It supports electricity from both the grid and solar PV systems, allowing full compatibility with renewable energy sources. The system efficiently powers domestic hot water, underfloor heating, and even cooling functions—all in one integrated solution. This smart energy synergy maximizes performance while reducing energy bills and carbon emissions.

Cascade Connection for Scalable Heating Needs

Solareast’s advanced cascade system enables the connection of up to 16 heat pumps in series, delivering a powerful and flexible solution for large-scale heating demands.

Ideal for residential complexes, commercial buildings, and industrial projects, the cascade setup efficiently distributes the load across multiple units, enhancing system stability and optimizing energy use.

With smart load balancing and modular control, this design ensures:

• Precise temperature regulation across different zones
• Reduced energy consumption and lower operational costs
• High reliability and minimal downtime

The scalable structure also supports future expansion without affecting performance—making it a future-proof choice for growing infrastructures. Whether for new developments or retrofitting projects, Solareast’s cascade system guarantees high performance, long-term sustainability, and maximum system efficiency.
