Flexible Heat Source Heat PumpflexoTHERM exclusive VWF 230V

The versatile premium heat pump.

Flexible choice of different heat energy sources
Very quiet thanks to integrated Vaillant Sound Safe System
Quality components made in Germany with high degree on recycling materials
Including internet module for conviently energy management via app
Optional use of flexoCOMPACT exclusive with integrated hot water storage tank

One heat pump, lots of options: Our flexoTHERM exclusive can flexibly use the environmental energy stored in the earth, air and groundwater depending on your wishes and the conditions on site. Hot water preparation can also be tailored precisely to your needs with a suitable hot water cylinder or a combination with solar thermal. Thanks to the integrated Sound Safe System, the heat pump operates very quiet. It ensures that all noise remains inside the unit and is decoupled from the outside.

Ideal for:

Heating
Hot water
Cooling
