With its straightforward and compact design, the x-change dynamic AW E air / water heat pump blends harmoniously into modern living spaces. Made of stainless steel, the robust top of the housing is slightly angled to allow rainwater to flow off easily, making this energy-efficient heat generator ideally geared towards outdoor installation. The ribs for air intake are fully integrated into the front. The separate control with touch display is highly practical and makes it easy to operate.
