Circulation pump not integrated into the heat pump!
The heat pumps are equipped with a continuously variable compressor and a brushless fan with variable speed control. This allows the heat pump to adapt to the energy demands of the heating system. The stable operation of the heat pump enables high performance with low compressor noise. The refrigeration system, equipped with EVI (Enhanced Vapor Injection) technology, ensures high efficiency even with conventional radiator systems.
- One of the most cost-effective ways to heat buildings. The system also works at temperatures as low as -25°C.
- High efficiency and long service life thanks to the use of components from world-renowned manufacturers
- A comprehensive control system ensures optimal monitoring and security. Internet control is possible. A wired control panel is included as standard.
- High ease of use. Intuitive and simple operation of the controls.
- The device's compact design allows for quick installation.
- Energy class A++ at 55°C flow temperature, A+++ at 35°C flow temperature
The ultimate feeling of comfort
NEXUS M EVI heat pumps enable optimal room temperature with minimal energy consumption. They allow the right air temperature to be achieved while simultaneously providing access to hot water to fully meet consumer needs.
Advantages of monoblock construction
The pump is designed entirely for outdoor installation. A key feature of the pump is that the entire cooling system is housed in a single unit, with only the pipes supplying heat to the building extending outside.
Working under 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.

Important NOTE!
The installation and commissioning of the equipment must be carried out exclusively by qualified personnel. In the event of a complaint, proof of proper installation by qualified specialists (certificate of professional qualification and special qualifications) must be provided. If no such proof is provided, all warranties and guarantees will be void.
Technical specifications subject to change without notice. Errors and omissions excepted. Subject to prior sale. Image may differ from actual product.
Refrigerant leaks contribute to climate change. Refrigerants with a lower global warming potential (GWP) contribute less to global warming in the event of a leak than those with a higher GWP. A leak of 1 kg of this refrigerant would therefore have a greater impact on global warming, proportional to the refrigerant's GWP value, than 1 kg of CO2, over a period of one hundred years. Do not attempt any work on the refrigeration circuit or disassemble the unit – always consult qualified personnel.
