The heat pump Vitocal 300-A from Viessmann sticks out first by its unique design. Inside, it hides features, which guarantee high quality, ease of use, functionality and ecology. The device has been designed for outdoor use by Phoenix Design. Just like a sculpture, the cylindric body can be installed free-standing and integrated into the respective architectural environment. In addition, the cyclinder ist the ideal form to integrate the fan – different from normal devices in cubic form – into the inside of the pump. The anthracite coloured slats enclose and structure the casing like a band. The Vitocal 300-A uses the outside air for heating as well as cooling and can be comfortablys controlled via an app from the living room.
