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).

Hello,
The owners must be in the category of “I don’t care about anything at all.”
First of all, a consumption of nearly 5000 kWh household electricity for two people is completely absurd. How is that even possible? We are three people and use about 2500 kWh. And we already run a NAS, laptops, receivers, etc. Yes, and we don’t only use candlelight!
Then: why would a private household pay 30 cents/kWh NET? I would have to check, but in 2014/2015 we paid 22–25 cents gross.
If they are so focused on that, it suggests that they probably keep all the windows tilted open all year round and still happily heat the house.
Another possibility:
With 18,300 kWh heating electricity, there is either no heat pump installed at all or it is broken, and they basically heat using electric backup heaters.
Rough estimate:
Heating period about 6 months = 24*362/2 = 4380 hours.
Average heating power: 18,300 kWh / 4380 h = 4.17 kW. That likely represents the average heating load in a house like this: so the heating is basically running almost entirely on electric heating right now.
Whatever is going on there: the heating system needs to be replaced. So steer clear!
Best regards,
Andreas

Ok, sorry, my mistake, that is gross.
The consumption remains at 5000 kWh household electricity and over 18,000 kWh heating energy. That can’t be right, can it?

A house (even from 2002) with 145 sqm (1560 sq ft) shouldn’t have a heating demand of more than 15000 kWh, including hot water! So it must be pure electric heating (such as fan heaters) at work!
5000 kWh of household electricity is basically impossible for two people. They must really not care about anything...
That could also work to your advantage since money obviously doesn’t matter to them!
