The highest level of comfort

NEXUS M EVI heat pumps enable optimal room temperature with minimal energy consumption. They allow for achieving the right air temperature while providing access to hot water to fully meet the needs of consumers.

Advantages of monoblock design

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 supplying heat to the building are led outside.

Operation 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.
