ᐅ Cabinet with air-to-water heat pump and water storage tank. Does anyone know this system?

Today, we had another energy consultation. Once again, we ended up a bit more confused than before.

Among other things, we were told about a heating option we hadn’t heard of before. It involves a cabinet that acts as a kind of heating center: it contains an air-source 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 around 20,000 € and requires very little maintenance.

To me, this sounds ideal. We could install our preferred wood flooring without underfloor heating, save a lot of money, and expect less maintenance.

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

Search for air-to-air heat pump or exhaust air heat pump: poor efficiency outside of a passive house. Don’t let anyone sell you on this; you won’t be able to fix the mistake later.

Do not forgo hydronic heating surfaces and keep ventilation and heating separate.

Ps: previous thread last post, user Nika.

What energy standard do you have?

Surely with decentralized ventilation?

There are combined units with air-to-water inverter pumps that are not connected to underfloor heating. However, a central mechanical ventilation with heat recovery system is necessary.

Why is wood flooring not suitable with underfloor heating?

Thank you for your responses @boxandroof
Why do ventilation and heating need to be separate?
The consultant is paid by the government, he didn't want to push anything on us, he has no personal interest in it

@haydee
Regarding ventilation, we are open to options. For me, it could also work without it, I have no problem with airing out the house..
Energy standard: I estimate we will be somewhere between 40 and 55.

Wood does not conduct heat very well. Underfloor heating is still allowed in this case.

Well, then there’s nothing against wood flooring, underfloor heating, and an air-to-water heat pump, right?

An exhaust air heat pump and air heating are not really effective. Neither alone nor combined. Both are more suitable for passive houses with extremely low heating demand.

But call him and ask for the manufacturer and model name, then we can assess further.

For now, we’re just guessing.
