• One of the most cost-effective ways to heat buildings. The system also works at temperatures of -25°C
• High efficiency and long service life thanks to the use of components from world-renowned manufacturers
• Extensive control ensures optimal system control and protection. Internet control is possible. A wired control panel is standard equipment
• High operating comfort. Intuitive and simple operation of the control
• The compact design of the device enables quick installation
• Energy class A++ at 55°C flow temperature, A+++ at 35°C flow temperature

The highest level of comfort

NEXUS M EVI heat pumps enable an optimal room temperature with minimal energy consumption. They make it possible to achieve the right air temperature while providing access to hot water to fully meet the needs of consumers.

Advantages of monoblock construction

The pump is fully designed for outdoor installation. Characteristic of the pump is the fact that the entire refrigeration system is housed in a single unit and only the pipes that supply the building with heat are led to the outside.

Working in extreme conditions

NEXUS heat pumps are innovative system solutions from SUNEX that keep your home warm even at extremely low temperatures down to -25 degrees Celsius. In operation, they offer exceptional efficiency, reliability and cost-effectiveness.
