ᐅ Which brine-to-water heat pump: Viessmann, Nibe, or Stiebel WPE-I 10 H?

Hello,
my two-family house (KfW40 standard, over 300 sqm (3,230 sq ft) of living space with underfloor heating) will be connected to cold local district heating (raw water), and the question is which brine-to-water heat pump (with passive cooling function) is optimal. I can freely choose between Viessmann, Nibe, or Stiebel. The heating capacity should be at least 9 kW. The installer initially recommended a Stiebel brine-to-water heat pump WPE-I 10 H 400 Plus with a sound power level of 44 dB(A). Are there any experiences with this or good alternatives?
Good luck, Alrico1

Meltem Heat Recovery II – am I correct in understanding from online sources that it is a decentralized system?
Make sure to have a central mechanical ventilation with heat recovery installed.
Actually, the mechanical ventilation system and the heating usually do not need to communicate with each other, unless you are an expert and want to optimize everything.
Normally, the mechanical ventilation quietly runs through its settings throughout the year and does not concern itself with what the heating system is doing.

The Meltem Heat Recovery II system is somewhere between centralized and decentralized. With 2 units, we supply an entire floor through flexible ducts in the ceilings, which then provide fresh air to the supply rooms (bedrooms and living rooms) and extract air from the exhaust rooms (kitchen/bathroom).
Hmm, if I’ve read that correctly, these units have an air flow rate of 100 cubic meters during intensive ventilation. For a living area of 300 m² (3,230 sq ft) with a ceiling height of 2.50 m (8.2 ft), two devices—one at the front and one at the back—won’t be enough. I would first do a proper ventilation plan and then choose the unit accordingly...
