ᐅ Air-to-water heat pump and controlled mechanical ventilation with heat recovery

Hello everyone,
I am planning to build a solid (masonry) house with KfW 70 energy standard. The external walls will be 36.5 cm (14 inches) Ytong. Approximately 230 sqm (2,475 sq ft) underfloor heating, one wood-burning stove, an air-to-water heat pump, and a controlled mechanical ventilation system with heat recovery. My question is, which heat pump would be the best solution for me? For example, the Novelan LA 14 RX (advantage: it has a cooling function), Vaillant geoTHERM, or one from Viessmann. I have read many negative experiences about the Viessmann units, but I would like to get some tips from you.
Regarding the controlled mechanical ventilation with heat recovery (central unit), has anyone had experience with PLUGGIT, or would you recommend another brand?
There will be an 8 kWp photovoltaic system installed on the roof later.
Thanks in advance

OK, and which air-to-water heat pump is better for me? I have listed the COP values below, but which one is also not an energy hog?
COP values given as A-7 / W35
1. Alpha-Innotec GmbH LW 121 (A) COP 2.91 11.3 kW
2. Junkers Bosch Supraeco SAO 110-1 COP 3.04 11.13 kW
3. Mitsubishi Electric EU PUHZ-SHW112V(Y)HA

Hello,
Just choose what you enjoy or what someone tries to sell you!
