Higher efficiency for the domestic hot water heat pump

The new Xchanger®safe safety heat exchanger is top in safety and efficiency


With the newly developed Xchanger®safe safety heat exchanger, the air/water hot-water heat pump is particularly cost-effective, low in maintenance and energy-saving. The heat exchanger is installed directly in the hot-water tank, ideally in the colder lower part. In the design of the heat exchanger, we have attached importance to achieving optimum heat transfer with minimum use of material.

Our offer for you

  • Development of highly efficient heat transfer surfaces
  • Product design and construction
  • Heat transfer laboratory with precise testing equipment

The heat pump therefore achieves peak COP values measured according to EN 16147. Security against contamination is provided by the double-wall GEWA-safe tube that makes any leakages recognizable through the standard-compliant leakage gap. A mixing of drinking water and refrigerant is impossible. The innovative Xchanger®safe heat exchanger not only offers you absolute reliability but also meets the highest efficiency standards.
