We are having an air-to-water heat pump installed as a split system by the general contractor. The contract states it will be a model from Viessmann, Junkers, or Wolff, with a 300-liter (79-gallon) hot water storage tank (without solar).
If I don’t bring up the topic again, they will probably just install whatever, although of course I will be informed beforehand about which device it will be. However, I’m interested in knowing what to pay attention to when it comes to air-to-water heat pumps and which of the three manufacturers generally has a good or bad reputation. Depending on your advice, I would share my preference with the general contractor to ensure that a good unit is installed.

As tomtom already said, take a look yourself at which heat pump has the better seasonal performance factor... or you can check the features of each heat pump... then you simply choose one...
Without explicit written notice to the general contractor (GC) in black and white, whatever unit is available at the time will be installed... basically whoever has time will come with their unit...
Ok, thanks. I didn’t know about the seasonal performance factor. I found this:
The seasonal performance factor, which is usually between 3.0 and 4.5, applies: the higher, the better! Basically, the seasonal performance factor of the heat pump should not be below 4.0. This means the heat pump delivers at least four times the energy it consumes.I’ll take a look at this from the different manufacturers then.
