ᐅ Heating via ventilation system with heat pump

Hello,

We are interested in a house that is currently for sale and are already in negotiations. We have now learned that there was a misunderstanding regarding the heating system. It is heated with a heat pump; until now, we thought there was underfloor heating. It has turned out that the heating is only provided through the central ventilation system, essentially using warm air. The seller presents this as a particularly high-quality heating system that was even more expensive. We would have found underfloor heating, at least in the bathroom, very comfortable.

Can anyone share information about this type of heating? What are its advantages and disadvantages?

The house was built in 2002 and has approximately 145 m² (1560 sq ft).

Doesn’t Schwörerhaus use this heating concept?

Best regards briefly

It is an Elk house. And I believe that the insulation is not bad, but also nothing exceptional.
According to some impartial opinions, we would get it at a very good price. But still, everyone here would advise against it, is that correct?

No, I wouldn’t discourage it. You just need to do the calculations for yourself. The house isn’t old, so it’s probably well insulated according to modern standards. Try asking this way: I know that this heating system can lead to very high electricity bills. Please provide me with two or three electricity bills. I’d like to run the numbers myself…

The background is this: you are buying the house relatively cheaply, and it otherwise meets your needs. If the electricity consumption remains reasonable—since there’s no gas involved, and that’s the only external energy source you are purchasing—the house wouldn’t be off my radar. Compare that to a typical gas boiler from 2002, with about 150 euros per month for gas plus around 3000 kWh of electricity for other uses; that would roughly represent a conventional 2002 house. So, about 250 euros per month. Karsten

Yes, I will ask him about that.

My wife and I are especially concerned about the bathroom, which is more or less unheated. There is only a small electric heater mounted on the wall. The rest of the house has laminate flooring, but the bathroom has tiles. Isn’t that quite cold?

Otherwise, the house is really very nice, with high-quality materials, a modern design, and an excellent location. It is 15 years old but was recently renovated with new flooring, new doors, and so on.

You commit to this concept for life because there are no pipes installed anywhere for a water-based heating system.

Exactly. But if the price and everything else is right... as I said, consider it. There’s always something when buying used. Karsten
