Aurax Mini is a reversible inverter air-to-water heat pump designed for heating, cooling, and domestic hot water production in residential and light commercial applications. Using natural refrigerant R290 with an ultra-low GWP of 3, the system combines high seasonal efficiency with reduced environmental impact and future-ready refrigerant compliance.
Designed for both new-build and modernisation projects, Aurax Mini supports high water temperatures up to 70 °C, making it particularly suitable for existing radiator systems where replacing the entire heating installation is not always feasible.
Its compact design, inverter operation, and flexible hydraulic configurations allow easy integration into modern HVAC systems while maintaining stable year-round comfort and optimised energy consumption.
Aurax Mini is designed to provide stable year-round operation across heating, cooling, and domestic hot water applications.
The system can prioritise DHW production while maintaining indoor comfort through intelligent operating logic that prevents excessive temperature drops in the heating circuit.
High-temperature heating without major system modifications
With water temperatures up to 70 °C, Aurax Mini can operate efficiently with existing radiator installations, supporting heating system modernisation projects without requiring complete emitter replacement.
Stable cooling performance during summer operation
The reversible inverter system provides chilled water down to 5 °C, enabling efficient summer cooling for residential and commercial applications.
Intelligent DHW management
Integrated DHW priority logic optimises hot water production while maintaining stable operation of the heating system and reducing unnecessary energy consumption.

The Aurax Mini 4-Pipe configuration enables independent management of heating, cooling, and domestic hot water circuits within one integrated system.
Summer mode — cooling and DHW at the same time
During cooling operation, recovered heat can be simultaneously used for domestic hot water production, improving overall system efficiency and reducing operating costs.
Winter mode — heating with DHW priority
The heat pump prioritises DHW production when required and automatically returns to space heating once the target temperature is reached.
Single-function operating mode
Depending on system demand, the unit can independently operate in heating, cooling, or DHW mode.
This flexibility makes Aurax Mini suitable for buildings with varying occupancy profiles and changing seasonal demand.
Aurax Mini uses propane (R290), a natural refrigerant with a Global Warming Potential of only 3 and zero ozone depletion potential.
Compared with traditional refrigerants such as R410A, R290 offers significantly lower environmental impact while supporting high operating efficiency and high-temperature performance.
The use of R290 also aligns with evolving European F-Gas regulations and decarbonisation targets, helping building owners future-proof HVAC installations against upcoming refrigerant restrictions.
AIC integrates dedicated safety measures and system protections compliant with current European standards, ensuring safe and reliable operation in residential and commercial environments.
Ultra-low environmental impact
The use of propane refrigerant with GWP 3 helps reduce greenhouse gas emissions while supporting compliance with future European refrigerant regulations.
Suitable for existing radiator systems
Aurax Mini supports high water temperatures without relying heavily on electric backup heating, making it well suited for heating system upgrades and replacement of older fossil-fuel boilers.
Flexible year-round HVAC operation
Aurax Mini combines space heating, cooling, and domestic hot water production in one compact system for residential and light commercial applications.
