Water/Water Heat Pump

Hello everyone,

first of all, a big compliment to everyone here, I have been reading for a while and it is really an extremely good and helpful forum.

Now to my question:
We are currently planning our single-family house and would like to take the opportunity to install a water/water heat pump for heating. However, I am an absolute layman in this field and also somewhat lost in the world of heat pumps and heating options.

My question now relates to hot water preparation. How do you sensibly combine this?
Is it possible to use a controlled residential ventilation system with heat recovery for hot water preparation, or is that not economical?
Solar might also be possible since the roof slope faces south.

The appointment with the energy consultant is still pending, as the architect’s plans are not yet completely finished.

Thank you for your advice

Controlled residential ventilation with heat recovery for hot water production??? Where is the energy supposed to come from for that?

Electric?

The whole topic of proper heating is more complex than anything else in construction... without specifying the heat demand, the discussion is hardly worthwhile... so first clarify what is actually needed...

Ok, I already thought it was relatively complex, thanks anyway. Then my next visit will be to the energy consultant after the architect.
