Nexus M EVI 18 kW heat pump
Monoblock inverter technology
The Nexus M EVI heat pump uses a continuously variable inverter compressor and a brushless fan with variable speed. This allows the output to adapt precisely to the actual energy demand, ensuring maximum efficiency both for heating and for domestic hot water preparation. Thanks to its low-noise operation, the sound power level remains pleasantly low, even at full load.
EVI refrigeration system for maximum efficiency
Thanks to Enhanced Vapour Injection (EVI) technology, the refrigeration system delivers outstanding performance even at low outdoor temperatures. Classic radiator systems benefit from the high flow temperatures just as much as underfloor heating. 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 unit that can be installed outdoors. Only the water-carrying pipes need to be routed into the building interior. This design saves installation effort, minimizes the risk of leaks, and makes the heat pump particularly easy to service. The compact dimensions of 1050 × 480 × 1330 mm allow for space-saving installation in the outdoor area of the property.
Intuitive control and networking options
An integrated touch display ensures easy operation and clear control of all system parameters. Extensive safety functions 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 (W55) in temperate climate and thus belongs to energy efficiency class A+++ at 35 °C flow temperature and A++ at 55 °C flow temperature. Equipped with a high-quality Panasonic compressor, electronic expansion valve and two variable fans, it delivers up to 7.15 A hot water output. The environmentally friendly refrigerant R32 with a GWP of 675 ensures sustainable heat supply.
Robust operation under extreme conditions
Whether Siberian frost or hot summer days – the Nexus M EVI operates reliably at outdoor temperatures from -25 °C to +45 °C. A defrost cycle via hot gas bypass keeps the system ice-free even in winter. The high-quality components from world-renowned manufacturers guarantee a long service life and low-maintenance operation.
