House Construction Cost Estimation - Does this fit?

And honestly, aren't all those with heat pumps now the ones screwed over, because they bought a significantly more expensive heat pump back then and are now financing the gas price brake for everyone else with their high taxes. Because if a large part of Germany can no longer afford gas consumption, those with heat pumps probably won't have a job anymore either. That's why the state is now providing such massive support.

I don't feel screwed over. The nearly 100K in subsidies (I once broke down how much was for what) for my semi-detached house, gas heaters first have to match that cap ;-) But you probably just forgot the [Ironie ON] and [Ironie OFF] tags?

I don't feel like I've been screwed over. The nearly 100K in subsidies (I once broke down how much was for what) for my semi-detached house need to be capped by gas heaters first ;-)

Even if I weren't green behind the ears, I wouldn't install a gas heating system today. You also have to somehow keep in mind what the house will be worth in 10 years. I believe gas is not a good investment there. That was already our motivation back in 2020 to pay the extra cost for the heat pump, and back then there was no war yet and gas was still a sweet 6 cents.

And fortunately, this subsidy craze came to an abrupt end at the beginning of the year. So now people at least don't have to rig a [Einliegerwohnung im Keller] to collect double. I have always thought that was wrong.

It's not just the granny flat, the BAFA-eligible WP+ventilation monster units worth as much as 2 new family cars were also an absolute wrong incentive. They actually cost an additional 30k compared to a simple gas heating system ;)

Our house was built according to the minimum standard of the 2017 Energy Saving Ordinance. Triple-glazed windows, thermal bricks, and so on. In conversations with friends, family, and colleagues, the 18000 KWH was always considered good.

The value refers to 170 sqm of underfloor heating plus 300 liters of hot water.

The quick heat was once related to the underfloor heating, because yes, when I want warmth I raise the flow temperature within minutes, we notice that quickly in the bathroom, for example. But mainly hot water, because once a week a thermal disinfection runs and quickly brings the 300 liters to over 70 degrees. With heat pumps, that is probably 100% electricity.

Please don’t misunderstand. Heat pumps are a great heating option, but I would still not demonize gas. By the way, about half of all German households heat with gas. The other half is divided among many other heating options. And there is little experience with heat pumps that are 20 years old or older. Our biggest fear back then was the investment risk if the pump stops working.

This was really sold to you as good? Our house, renovated in 2008 and built in 1930, is better off. So, my parents have had a heat pump for over 15 years (by the way without underfloor heating) and are still convinced by the technology. The whole thing has long since outgrown its infancy.

Our house, renovated in 2008 with a construction year of 1930, is doing better.

My parents have had a heat pump for over 15 years now (by the way, without underfloor heating) and are still convinced of the technology.
This whole thing has long since grown out of its infancy.

Nobody sold that to us, we planned it ourselves.

Now you've made me uncertain and I checked again. The figure of 18,000 kWh refers to the first year, in which we ran the underfloor heating program in summer and of course ventilated a lot in the months out of fear of residual moisture in the walls shortly after moving in, sorry, my mistake.

Last year it was 12,200 kWh.

Important: We did not build according to any KFW guidelines. Only the mandatory energy saving ordinance (because we wanted it that way). We have comparatively high ceilings. In two areas of the house, the ceiling is open to the roof slope. We insulated between the rafters under a hip roof. Therefore, there is no cold attic and unfortunately, currently, no door to the attic (staircase is not foldable, fixed space-saving staircase). I've wanted to take care of that ever since moving in but two kids and a few other projects came in between :-D

What I want to say with this: The living climate is great, I am satisfied with the energy costs for the volume but am also interested in the energy costs of others, regardless of the type of heating. I now pay 160 euros/month for heating (heating + water).
