Construction costs are currently skyrocketing

How much does a switch from a gas condensing boiler to a heat pump (air-water) cost? Just a rough estimate.

I don't know, as we haven't gotten any craftsmen, as I said. Our heating company will at least come in September to prepare an offer for next year; they also have a partner company for photovoltaics. There will be additional costs because, in the process, we would finally renew the 100-year-old original plaster as well as the original floor structure, which means we would tear up the entire ground floor, install underfloor heating there, and insulate to the basement; as I said, we would also renew the interior plaster. Or maybe nothing will happen at all if it turns out to be too expensive...

The assumption that no heat pump subsidy is needed because only "rich" people have houses anyway completely forgets rural areas. Here, an extremely large number of people own their homes. It feels like the majority of families. There is more or less every income level. Everything is also represented in terms of renovation status.

But people in rural areas are not the target group of the Greens ;)

Is that even allowed in Germany yet? I understood it as not being possible yet, because regardless of the technical possibility, which as you said is slowly coming, there still need to be legal implementations to enable bidirectional charging?! Yes, for example, I use the electricity cloud from Senec. What I feed in during summer, I can take back from the grid in winter. Last year, the kWh from the grid cost me about 20 cents. And I don't have to pay any additional monthly basic fee.

I paid 24 cents per kWh last year; for that, I wouldn’t have gone through the photovoltaic hassle now... But with 8000 kWh consumption (with air-water heat pump and electric car) and new prices of 30-40 cents per kWh, I just lay down the 20K. And then with a storage system, I am at least often self-sufficient (designed specifically with backup power function)... This won’t be popular here again, but my neighbor was right when he said right after the election: Greens in government? I’m quickly ordering photovoltaic... I thought I’d wait because they would support it or something... instead, they are destroying everything (my opinion)

I don't understand why you want to get rid of the oil heating system. It is probably currently the cheapest and safest form of heating besides the heat pump.

And especially in existing buildings, it makes perfect sense. Better save up for a photovoltaic system and combine both. It has never been advisable to change everything just because something is currently fashionable. As I have written several times, I see the heat pump similarly to the storage heaters in the 80s.

Nobody wants those anymore today. Many heat pump owners don't even have a chimney in their house. That will come back to haunt them. Certainly, it always depends on the region. It makes a difference whether the house is in the Bavarian Forest or in the Rhine Valley.

Was that directed at me? Unfortunately, photovoltaic is going to be difficult.. There is solar on the roof and hardly any space for photovoltaic (due to dormers, the roof is quite convoluted). We have a chimney and I already liked heat pumps even before they became widespread.. My parents replaced their oil heating system with a heat pump and a water-bearing fireplace (for the really cold days) about 15-20 years ago. Works great. We could do something like that too thanks to the chimney.

I paid 24 cents per kWh last year; for that, I wouldn't have put myself through the photovoltaic stress now…. But with an 8000 kWh consumption (with air-to-water heat pump and electric car) and now 30-40 cents per kWh, I'll just lay the 20K on the table. And with the storage, I'm at least often self-sufficient (designed specially with an emergency power function)… This won't be well received here again, but my neighbor was right when he said right after the election: Greens in the government? I'll quickly order a photovoltaic system… I thought I'd wait because they would support that or something… instead, they are destroying everything (my opinion)

That's true. I assumed that reasonable renovation and new construction subsidies would be increased or at least remain the same. Instead, environmentally harmful subsidies that have existed for years are being cut. It's a shame; to be honest, I was happy about the composition of the government.

I paid 24 cents per kWh last year, I wouldn’t have gone through the photovoltaic stress for that…. But with 8000 kWh consumption (with air-water heat pump and electric car) and now 30-40 cents per kWh, I just put the 20K on the table. And with storage, I am at least often self-sufficient (specifically designed with emergency power function)… This probably won’t be welcomed here again, but my neighbor was right when he said right after the election: Greens in government? I’ll quickly order a photovoltaic system… At that time, I thought I would rather wait because they would promote it or something… Instead, they are destroying everything (my opinion)

Until March, I had a "green tariff" with just under 23 cents gross for the old house/office and a rented residential unit. But that was with 14,000 kWh o_O. Then the announced tariff increase. The cheapest tariff available online here in March 2022 would have been 42 cents!! I was lucky that GreenPlanet Energy took me on as an additional location for 31 cents. Still, I now end up with 418€ every month (of course mostly operating costs, but still annoying). Photovoltaics almost impossible (old, jagged, crooked, and steep roof, and mostly incorrectly oriented) Now, of course, one can say "if only…", but that the Greens are destroying everything cannot really be claimed. They are mostly taking now absolutely necessary steps that hurt everyone a little, some more, some less. These steps would have been gentler if they had been spread over the last 20 years; we probably wouldn’t have even noticed. The situation we are in really cannot be blamed on the Greens, since they were hardly involved in governing anywhere. We will all have to make sacrifices; if for you it’s just losing freebies (photovoltaic subsidies), then that’s okay. ;)
