ᐅ Possible House Purchase – Air-to-Water Heat Pump Could Become a Money Pit

Hello experts.
A house that was built solidly three years ago (without insulation) is up for sale.
The house is equipped with an air-to-water heat pump as well as a fireplace. There are no solar thermal or photovoltaic systems.
Heating is provided by the air heat pump and the fireplace, and an energy performance certificate is available. The values have varied somewhat over the three years, but well.
The seller gave me the invoice for the heat pump and the underfloor heating yesterday.
How can I tell if this is a "good" energy concept?
Before I buy, I want to make sure I’m not getting into a money pit.
Do I possibly need the exact external wall thickness (which type of masonry), roof insulation, window specifications, etc. for that?
I would appreciate any information. Have a nice evening and best regards, Chris

doch, die 8000kWh sind pro Jahr der Heizung zuzuschreibenThat is not normal. Not normal at all. That consumption corresponds to an electric resistance heating system, not a heat pump. You would rather expect about one third of that.
How large is the house? 600m² (6,458 sq ft)?

A controlled residential ventilation system often isn't cost-effective, but rather a "luxury." You simply don’t have to ventilate manually anymore, which is still necessary in new builds due to the airtight building envelope.
People build the house airtight and then open the windows wide every day instead of recovering heat through a heat exchanger—very clever.
