Yes, I will also install these.
The heating element is turned on from the bivalence point. It depends on the load according to the mode of operation. More in the range of -5° to -9°.
The heat pump should generally not be used below -20°. But that is rather unlikely for us.
Yes, the minimum temperatures really depend heavily on the latitude in Germany. In the south, you will probably need to choose an air-to-water heat pump with a lower bivalence point.
**Edit: Are there actually air-to-water heat pumps that switch on a small gas boiler when the bivalence point is reached? Instead of an electric heating spiral.**
