Construction costs are currently skyrocketing

Thank you for your tips. We will now try MyHammer. Then we decided that my husband will try the plumbing. Called this morning and received a callback from the boss half an hour ago. It could be a coincidence, no idea, or not, I don’t want to assume anything. But in any case, he says he will do it this year: underfloor heating and solar thermal, and the connections for the interim kitchen in the basement. He will finish the offer, as he already knows the conditions on site. If we now find a company for the rest, I will be happy.

I have also assigned a few things through MyHammer. Moving, for example. I haven’t had any bad experiences.
For me, it was similar with the energy consultant back then. I didn’t even see him once. I thought that was good, because some have done it more or less on the side and ultimately know less than I do. I preferred to pay the money for the "inspection" and the signature rather than x in-person appointments with possibly poor advice and more money.

@TE: I don’t really understand solar thermal either...

With solar thermal energy, everyone in the area has only good things to report. In combination with the gas heating, it’s a good thing. Whether it pays off, certainly not very quickly, but neither do 30,000 EUR and up for heat pumps and photovoltaics. If we approach this economically, we can simply continue burning gas.

The Renewable Energy Heat Act mandates the use of renewable energies. Solar thermal can be a component to meet the required quotas. It therefore pays off faster through subsidies than through actual energy savings.

That is correct. However, as far as I know, this applies to new systems; we will keep the old gas heating system for at least a few more years (it is from 2010), so we are not subject to this obligation. It is rather an ecological decision to save gas.

Compare the offer for solar thermal with photovoltaics + (DHW heat pump or heating rod).
