ᐅ Recommendations for Air-to-Water Heat Pumps with Integrated Central Ventilation Systems

GlemboHello,
we are planning to build a new semi-detached house. KfW 55 standard, 2.5 stories, about 155m² (1,670 sq ft).
For the heating system, I have chosen an air-to-water heat pump.
I personally find decentralized ventilation (each room has an exhaust duct in the external wall) unaesthetic.
I much prefer the option of an integrated central ventilation system.
However, I’m open to being convinced otherwise! I am definitely not an expert.
Now my question:
can anyone recommend a reliable and efficient device?
My building consultant recommends a model from Vaillant.
An independent consultation will take place next Thursday at a local heating company.
Best regards and thanks

I believe the one currently being offered to me is the Vaillant Arotherm. It does not have integrated ventilation.
I would prefer an air-to-water heat pump with integrated ventilation because that way I don’t have an outdoor unit, and I also avoid having an external duct with a manual tilt switch in every living space.

These are two completely different things. What you are looking for is an air-to-water heat pump with indoor installation (not a split unit with an outdoor component). It draws air through large openings, but still from outside. The air is used to extract thermal energy and is then discharged cooled back outside. The heat is transferred to the underfloor heating system and the hot water storage tank.
A ventilation system is a separate matter. It also draws in outside air, but significantly less and continuously; it supplies fresh air into the living spaces and extracts used air from them, directing it outside. With heat recovery, the exhaust air transfers its energy to the incoming fresh air (purely mechanical, no heat pump involved).
There are units that do both. Typically, these are exhaust air heat pumps, which do not use outside air as an energy source but only the exhaust air from the house. This is effective mainly in passive houses.
I would also avoid decentralized units and prefer a central ventilation system. However, it’s not cheap for a reason.
