The x-change dynamic terra BW I brine/water heat pump is an extremely energy-efficient heat source. The monolithic housing combines attractive form and efficient function. It integrates harmoniously into modern living spaces, and appeals thanks to its high-quality design and coherent coloring. A green splash of color decorates the front, symbolizing the fact that this heat source uses renewable energy.
