Nexus M EVI 18 kW heat pump
Monoblock inverter technology
The Nexus M EVI heat pump features a continuously variable inverter compressor and a brushless fan with variable speed. This allows the output to precisely match the actual energy demand, ensuring maximum efficiency for both heating and hot water production. Thanks to its quiet operation, the sound power level remains pleasantly low, even at full capacity.
EVI refrigeration system for maximum efficiency
Thanks to Enhanced Vapor Injection (EVI) technology, the refrigeration system achieves outstanding performance even at low outdoor temperatures. Both conventional radiator systems and underfloor heating systems benefit from the high flow temperatures. Efficiency remains stable even at -25 °C, making the Nexus M EVI the ideal choice for regions with cold winters.
Advantages of the compact monoblock design
The entire cooling system is housed in a single, outdoor unit. Only the water pipes need to be routed inside the building. This design saves on installation costs, minimizes the risk of leaks, and makes the heat pump particularly easy to service. Its compact dimensions of 1050 × 480 × 1330 mm allow for space-saving installation outdoors.
Intuitive control and networking options
An integrated touchscreen display ensures easy operation and clear monitoring of all system parameters. Comprehensive safety features protect against frost, overheating, and power fluctuations. If required, the heat pump can be integrated into smart home systems via an internet connection and monitored remotely.
Performance data and technical specifications
The Nexus M18 EVI achieves a SCOP of 4.46 (W35) and 3.51 (W55This unit operates in temperate climates and therefore belongs to energy efficiency class A+++ at a flow temperature of 35 °C and A++ at 55 °C. Equipped with a high-quality Panasonic compressor, electronic expansion valve, and two variable-speed fans, it delivers up to 7.15 A of hot water output. The environmentally friendly refrigerant R32, with a GWP of 675, ensures a sustainable heat supply.
Robust operation under extreme conditions
Whether Siberian frost or hot summer days – the Nexus M EVI operates reliably in outdoor temperatures from -25 °C to +45 °C. A defrost cycle using hot gas reversal keeps the system ice-free even in winter. High-quality components from world-renowned manufacturers guarantee a long service life and low-maintenance operation.
