This air/water heat pump was designed for outside operation and utilises the surrounding air for both heating and cooling. The innovative, cylindrical construction has a noise-optimising effect, making the pump one of the quietest in its class. Like a sculpture, the cylinder can be positioned in a free-standing way, blending harmoniously with its architectural surroundings. Moreover, in contrast to traditional cube-shaped devices, the cylinder features an ideal shape for integrating the ventilator into the interior of the device.
