ᐅ Is it possible to have a gas boiler without a solar system?

Hello,
we are currently building a solid masonry house with 36.5 Poroton blocks, a gas boiler, no external insulation, and no ventilation system.
Therefore, we do not meet any KfW requirements. The building permit / planning permission includes a solar panel system. Since I am not a fan of solar panels and would like to save around €5000, I am trying to avoid installing it. Is there a way around this? To comply with the energy saving ordinance, the system is basically required. However, my architect said that no one actually checks whether the system is installed or not. We would prepare all the necessary wiring, and if someone really notices the absence of the system, it could still be installed at short notice. Is there any problem with this approach?
I have already spoken with other "experts." Some said there would be no problem, others warned of a potential fine... the building authority would not check, but the chimney sweep might... then I asked the chimney sweep, and he said he wouldn’t check either...
So I am not really sure where I stand. Of course, I don’t want to skip the system and then, in 10 years, have to pay a hefty fine because it was checked somewhere.
Now I could really tear myself and my architect apart.

@futtinger, maybe your initial question was a bit unclear. I just reread it, and it sounds to me like: "I have the ST included in the building permit / planning application and want to simply leave it out. What could happen?"
And that’s different from what you’re asking now...
If you want to leave out the ST but still comply with the legal requirements (i.e., meet the energy-saving regulations), you should first run the house through the calculation without the ST. That way, you’ll know where you stand. Then, whoever performs the calculation should hopefully be able to tell you which parameters you need to adjust (insulation, windows, controlled ventilation system) to meet the 85% rule, which then allows you to omit the ST with a gas heating system. After that, you will probably need to submit an amendment to the building permit / planning application since quite a few things will change.
I’m going through the same process right now. Whether it’s ultimately worth it, especially after potentially spending money on new energy-saving regulation calculations and permit amendments, remains to be seen.
Since you plan to build monolithically with 36.5cm (14 inches) Poroton blocks, this could be quite tight. Even with a T8 Poroton block, you only get a U-value of 0.21. Will that be sufficient?
I am currently having calculations done for a wall assembly with a U-value of 0.16 and windows with a thermal transmittance of 0.5 W/m²K. Let’s see what comes out of it. I hope I can achieve the target with some additional insulation on the upper floor ceiling.
Best regards,
Andreas

The windows are installed as well. They are triple-glazed with a U-value of 0.89.
We have insulated generously—both the upper floor ceilings and the entire attic space.
I will probably have to ask my architect to recalculate everything.

The shell is already built? Then you can probably skip the consideration of choosing a different type of brick... Planning for a mechanical ventilation system with heat recovery is also no longer an option...
Which brick did you choose?
At this point, you can only hope that it will be sufficient, and if not, to build the pitched roof.
Let us know what the calculation results showed.

@futtinger, you are expressing exactly how I feel. For years, I have been living in a gray area, not paying the broadcasting fee. I simply refuse to accept being forced to follow those rules. But of course, I have the application ready in my drawer because when the official comes, I won’t show any remorse—I will just say that I was about to register.
I do the same with the waste disposal. Are they crazy to charge such high fees? I now have a 20-liter (5-gallon) bin, which of course is not enough for the whole family... I send my husband out at night to take the trash away—where to, I don’t care. Probably into the forest, but that doesn’t bother me since I don’t use it.
I support you in outsmarting the regulations, mocking the stupid official who stamped the approval on your building permit / planning permission for your house. And mocking us who actually comply with the energy saving regulations.
Best regards
Because of a like on my post, I want to stress that this message should be understood completely ironically. For me, there is even the question of fraud, since I also understand that the construction was only approved due to the planned solar thermal system, as it seems to be the only way to build in compliance with the energy saving regulations.
