Cabinet with air-water heat pump, water storage.. Does anyone know it?

Today we treated ourselves to an energy consultation again. Once again, afterwards we are a bit more confused than before.

Among other things, because we were told about a heating option that we didn't know.
It's about a cabinet that serves as a kind of heating center: it contains an air heat pump, equipped with a hot water storage tank and connected to a decentralized ventilation system.

The warm air is 'distributed' by the ventilation system, the entire cabinet costs about 20K € and requires very little maintenance.

To me, that sounds fantastic. We could install our desired wooden floor without underfloor heating, save a lot of money, and expect less maintenance.

I can't find any useful information about this online. Does anyone know this simple system? And the pros and cons?

Search for air-to-air heat pump or exhaust air heat pump: poor efficiency outside of passive houses. Don’t let anyone sell you on it, you won’t be able to fix that mistake later.

Don’t give up on water-based heating surfaces and separate ventilation and heating.

Ps: previous thread last post, user Nika.

What energy standard do you have?

Sure with decentralized ventilation?

There are combination units with air-water inverter pumps that do not have underfloor heating connected. However, a central controlled residential ventilation system is necessary.

Why doesn't wooden flooring work with underfloor heating?

Thank you for your answers
Why do ventilation and heating have to be separate?
The consultant is paid by the state, he didn’t want to sell us anything, he gains nothing from it


Regarding ventilation we are open, as far as I’m concerned it could also work without, I have no problem with airing..
Energy standard: I estimate we will be between 40/55.


Wood does not conduct heat particularly well. Underfloor heating is still not forbidden in this case

Thank you for your answers -

well then there is nothing against wooden floors, underfloor heating, and air-water heat pumps, right?

Exhaust air heat pumps and air heating are no good. Neither separately nor together. Both are things for passive houses with extremely low heating load.

but, call him, he should name the manufacturer and model, then we can see further.

for now we are just guessing
