ᐅ Installation of a Gas Heating System in New Construction 2023/2024

Hello fellow home builders,

we have started constructing a single-family house. The approved building permit / planning permission includes a gas heating system, which we still want to install.

There are two possible scenarios:

1. What happens if the heating system is installed in October 2023, but the house is only inspected and approved in February 2024?

2. What happens if the heating system is installed in January 2024, and the house is inspected and approved in May 2024?

Both options are difficult to plan for. So far, we do not know whether the construction schedule might be delayed.
I haven't found any information on this. Do you have any further details?

Regards,
robert0815

Well, the image title is at least misleading. They write "don’t know if it helped," but the correct phrasing would be "don’t know how much it helped." That is an important distinction. One statement can be supported by evidence, the other is inflammatory nonsense.

Exactly, this brings us back to interpreting texts that come from the fringe of the spectrum.

I have actively participated in the discussion here, but we should now come to a conclusion and provide the original poster with an answer.
The draft law can be found by searching online, and I came across a few points that should be noted if you are in the situation (or a similar one) to the OP. I have not cited the exact articles and paragraphs as sources, but anyone interested can simply use Ctrl+F to look them up themselves.

  • "If the property owner delegates the heating or domestic hot water supply to a contractor, both the property owner and the contractor are subject to the obligations concerning the requirements for the condition of the heating systems or other requirements for the building or an efficiency status according to § 8 paragraph 2, as a contractor acts on behalf of the property owner."
  • -> This means that property developers, general contractors, and/or heating installers can also be held liable. It’s best to clarify this with them. I can easily imagine a company not wanting to take any risks here. Perhaps you can reach an agreement on any additional costs.
  • "If a switch of the gas distribution network to hydrogen is planned by December 31, 2034, the property owner may install a gas heating system that can burn both gas and hydrogen. In this case, they are required to source 50 percent green gases (gaseous biomass or green or blue hydrogen including derivatives made from it) from January 1, 2030, and 65 percent green or blue hydrogen from January 1, 2035."
  • -> It might be worth talking to the local municipality or utility company about this. If something like this is planned, it could be an option.
  • "The installation of heating systems based solely on fossil fuels – especially gas and oil heating systems – will no longer be permitted from 2024 onward." and
  • "The enforcement of this regulation will be ensured during the installation of a heating system in a new building as part of the declaration of compliance according to § 92 paragraph 1."
    -> Here is the answer we were looking for. The inspection takes place when the heating system is installed, not during the building permit/planning permission process. I did not find any transitional period mentioned in the law.

To directly answer the questions:
  • Everything is fine here. Gas heating is okay.
  • You are in trouble and will have to replace the heating system.
The decisive date is the installation of the heating system. However, to avoid any risk, I would generally recommend switching to a heat pump. Since your general contractor/developer is also liable, you might be able to come to an agreement with them.

It is also currently uncertain how high gas prices will be in, for example, 15–20 years. It is quite possible that the gas network will be shut down or converted to hydrogen within 20 years. If you decide to go with a gas heating system, make sure it is 100% hydrogen-compatible.

Personally, I find this too uncertain and would opt for the more secure solution.

But it is and remains a draft. The final law could turn out very differently, especially since Habeck himself is facing significant opposition within the coalition government.
In conclusion: At the moment, no one can give a definitive answer on this.

Of course. That is clear. But the original poster asked, and this or a modified version will most likely come into effect. I only provided the information that the draft offers, along with my assessment. Ultimately, the decision has to be made by the original poster.

I believe the term "contractor" means something different here.
It’s about the supply, not the installation.
So, more like district heating or local heating where the technical equipment is also rented from the supplier. Something similar to the neighboring thread.
Possibly in multi-family residential construction there are setups where the main landlord fully outsources the heat supply.
