Aurax Mini Ni 10-40
Aurax Mini -
High temperature R290 heat pump
for retrofit and low-carbon heating
10–40 kW
Efficient heating upgrades
for existing homes and commercial buildings
Aurax Mini is a reversible inverter air-to-water heat pump developed for residential and light commercial retrofit projects where maintaining high flow temperatures is essential.
Using natural refrigerant R290 with an ultra-low GWP of 3, Aurax Mini combines low-carbon heating with high-temperature performance, making it suitable for replacing traditional gas boiler systems while reducing energy consumption and emissions.
The unit delivers heating, cooling, and domestic hot water from a single compact system and can produce water temperatures up to 70 °C, allowing many existing radiator systems to remain in place during heating system upgrades.
This makes Aurax Mini particularly suitable for UK properties where full emitter replacement is often impractical or cost-prohibitive.

High-temperature heating
with lower carbon emissions
Aurax Mini is engineered to support the transition from fossil-fuel heating systems to low-carbon HVAC solutions without compromising indoor comfort.
High flow temperatures up to 70 °C
Unlike many conventional heat pumps, Aurax Mini can operate at high water temperatures, helping maintain compatibility with existing radiator installations commonly found across UK buildings.
Efficient operation during colder weather
The inverter-driven system maintains stable heating performance at low outdoor temperatures while optimising seasonal efficiency and reducing unnecessary cycling.
Heating, cooling and domestic hot water in one system
Aurax Mini combines space heating, summer cooling, and domestic hot water production within one integrated solution, simplifying installation and system management.
Heating
up to 70 °C
Cooling
down to 5 °C
External temp.
down to -10 °C
Energy Class
A+++
4-Pipe system
with simultaneous cooling and hot water recovery
Aurax Mini 4T models allow independent control of heating, cooling, and domestic hot water circuits while improving overall energy efficiency through heat recovery.
Cooling and domestic hot water at the same time
During summer operation, recovered heat from the cooling cycle can be used to produce domestic hot water, significantly reducing overall energy demand.
Intelligent DHW priority control
The system automatically manages domestic hot water production without compromising space heating performance or occupant comfort.
Flexible operating modes
Aurax Mini can operate independently in heating, cooling, or domestic hot water mode depending on seasonal building requirements.

Natural refrigerant R290
Prepared for the future of low-carbon heating
R290, also known as propane, is a natural refrigerant used in various cooling and air conditioning applications. It is highly efficient and has excellent thermodynamic properties, making it an eco-friendly alternative to synthetic refrigerants. One of its key advantages is its very low Global Warming Potential (GWP) of just 3, meaning it has a minimal impact on climate change compared to traditional refrigerants like R134a or R410a, which have significantly higher GWP values.
