Domestic hot water heat pump + air-to-water heat pump?

Hello,

since we are currently blessed in the rental apartment with a domestic hot water heat pump (extremely low additional costs for hot water), I just had the thought whether it is possible to operate a domestic hot water heat pump additionally or independently from the air-water heat pump for heating in the planned new house?! Our preferred option would be the one with gas/solar as well as domestic hot water heat pump, as we have now. The air-water heat pump cannot prepare hot water, or have I completely messed that up?! I am a complete beginner in this field.

Where does my warm water for the shower and cooking actually come from? From the hydraulic tank of the air-water heat pump? And how does the water flow into the underfloor heating?

Maybe I also have a conceptual error. Feel free to enlighten me.

The air-water heat pump also heats the water for you, with a storage tank next to it (or internally as a compact unit). Hot water and underfloor heating are produced separately at different temperatures.

Oh, thanks Alex85! The post is a bit embarrassing for me right now, but now I understand. I didn’t know about the two separate systems. :-) Better we just forget about it. Dear Mod, hereby I submit a request for deletion!

I have a Vaillant Arostar air-to-water heat pump for our domestic hot water, works really well, super quiet (the previous model was very loud), inexpensive to maintain/electricity costs. I would definitely do it again.
