Nexus 8 kW heat pump

Monoblock inverter technology

The Nexus monoblock 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 heat demand of your heating and hot water systems. Thanks to EVI (Enhanced Vapor Injection) technology, the cooling system achieves high efficiency even at low outside temperatures.

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

Maximum operating comfort and intelligent control

A user-friendly touchscreen control system allows for intuitive handling 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 processes and protects the system with integrated safety features. This ensures reliable heat supply and drinking water comfort at all times.

Advantages of the monoblock design

As a monoblock outdoor unit, the Nexus contains all the cooling circuit components in a single housing. This simplifies installation: Only the heating water lines are routed into the building. Complex refrigerant lines are completely eliminated.

Thanks to its compact dimensions and low weight, the heat pump can be installed quickly and space-savingly. Its robust design is ideal for year-round outdoor use.

Reliable operation at extreme temperatures

The Nexus heat pump reliably delivers heat even at outside temperatures as low as minus 25°C. 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 from -25 °C to +45 °C and offers maximum reliability in every climatic region.
