Construction costs are currently skyrocketing

This is now off-topic:

That might depend on which car manufacturer you compare it to. I can only say that the Stuttgart car manufacturers can easily keep up...
I’m not sure about chemistry, but in my opinion, chemistry generally pays worse than metal, and the top of metal is the car manufacturers.

I don’t get my apprenticeship paid there though (chemical technician)

Classified in E4

3050€ basic salary gross
+ 305€ (10% shift allowance)

20% for rework
Holiday pay 30€ per day (30-33 days)
100% Christmas bonus
Performance bonus approx. 700-1200€

About 42-45k gross per year

It’s good, but inflation is already eating away quite a bit of the value until 2025

I don't know what you want to tell me right now? Maybe I didn't understand, my statement only referred to the one from , that chemistry would pay better than automotive. I doubt that.

And for the solar thermal system 10,200€ with everything. Domestic hot water + heating. I think these are normal, acceptable prices.

I think that's a lot. In case of doubt, you've basically already paid for half a photovoltaic system. I'll just say this once (ultimately it's your decision), but I don't see any point in solar thermal here. I would leave it out and rather try to install a photovoltaic system in a few years. Even without a heat pump, it should pay off faster through self-consumption than the solar thermal system.

Oops Yes, metalworkers earn somewhat higher. Chemistry is always in 2nd-3rd place.

We actually now have the first partial offer for our EG renovation. About 100€/m2 for laying and connecting the underfloor heating. Only the installation of the thermostats is not included. And for the solar thermal system 10,200€ all inclusive. Domestic hot water + heating. I think these are normal, acceptable prices. And the structural engineer charges 62€/h, which is also normal according to my research.

Hi, I quickly compared it with our prices from 2019: All prices net, and with connection by a specialist company. (Bavaria) Solar system 5 sqm with 300l storage - 4600€ Underfloor heating with insulation 210 sqm - 10,500€ Gas boiler with all connection gear and LAS chimney - 5000€ In hindsight, I found the underfloor heating expensive because for plumbing it is "no" work... We could have done it ourselves.

10k for solar thermal, which you'll have to tear down again anyway to install photovoltaic later, I (!) don't find a sensible investment. Save yourselves that and go for heat pump and photovoltaic later when it makes financial sense. The solar thermal system is already half the price of photovoltaic. Think it over again, we all only mean well. Thanks to underfloor heating, a heat pump will also work without any problems.
