Nexus 8 kW heat pump

Monoblock inverter technology

The Nexus monobloc inverter heat pump features a continuously variable compressor and a brushless fan with variable speed control. This allows the system to continuously adapt to the current heating and hot water demand. Thanks to EVI (Enhanced Vapor Injection) technology, the refrigeration system achieves high efficiency even at low outdoor temperatures.

Another advantage is the stable operation with reduced compressor noise, ensuring a peaceful living environment. The system guarantees consistently high performance without compromising on comfort or operational reliability.

Maximum ease of use and intelligent control

A user-friendly touchscreen control allows for intuitive operation of all functions. Time programs, temperature settings, and defrost cycles can be easily configured – either via the wired control panel or remotely via the internet.

The intelligent control system ensures optimal operation and protects the system through integrated safety functions. This guarantees a reliable heat supply and domestic hot water comfort at all times.

Advantages of monoblock construction

As a monoblock outdoor unit, the Nexus contains all refrigeration circuit components in a single housing. This simplifies installation: only the heating water lines need to be run into the building. Complex refrigerant lines are completely eliminated.

Thanks to its compact dimensions and low weight, the heat pump can be set up quickly and in a space-saving manner. Its robust design is ideally suited for year-round outdoor use.

Reliable operation at extreme temperatures

Even at outside temperatures as low as -25°C, the Nexus heat pump reliably delivers heat. Hot gas defrosting ensures rapid thawing of the evaporator surfaces and minimizes energy losses during the defrosting process.

The system operates stably in the operating range of -25 °C to +45 °C and offers maximum reliability in every climate region.
