New: MSZ-RZ – an air-to-air heat pump with natural R290 refrigerant

One of the first wall-mounted heat pumps on the market with natural R290 refrigerant: GWP of just 0.02, heating down to −35 °C, matte white or matte black.

MSZ-RZ is one of the first air-to-air heat pumps on the market with natural R290 refrigerant, designed for a northern climate. R290 has a GWP of just 0.02, so its climate impact is very low.

Heating works from +24 °C down to −35 °C outdoors, so MSZ-RZ can heat rooms all winter. The indoor unit comes in matte white and matte black.
