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

No. If the controlled residential ventilation system had cost another 10 with such a unit and you then saved twenty euros in electricity per month, it would have to run for a very long time. The technology is more likely to break down before that becomes worthwhile. Karsten

Something doesn’t add up. €210 (about $230) for electricity per month—can that really be attributed to the heating? How large is the house? With €210 (about $230), you could easily heat a house using an electric space heater. That has nothing to do with a heat pump at all.
A controlled mechanical ventilation system often does not make financial sense and is more of a "luxury." Manually ventilating is still necessary in new buildings due to the airtight envelope.
Regarding 2013, I assume the heat pump was very poorly adjusted. You would need to really get into the details there.
