Soundproof wall against neighbor's heat pump

...Then simply another gas is pumped into the virtually infinitely large gas/gas reserve network of Germany. This gas network and the reserves are probably by far the largest energy storage systems worldwide. And easily and gradually convertible from fossil to completely non-fossil.

Off-topic: And how is the CO2 balance with non-fossil gases?

e.g. to take a non-registered association.

Which brings me back to the question of liability in supply contracts or costs in case of a defect, if a member cannot or does not want to pay.

So: Who is liable and how?

Unfortunately, you didn’t inform yourself properly.

is just an example with "his" gas heating in this discussion. The main thing is to keep the place as cheaply warm as possible..

There are already 100% biogas tariffs for just under 10 cents. That is the current state of technology and this price will still decrease in 10, 20 years, as soon as this becomes interesting.

Yes, today biogas only interests enthusiasts, right? I was shocked that biogas is twice as expensive as our municipal utility (under 5 cents). The average person mostly looks out for their own wallet.

For electricity, it's only about ~13% more expensive. The threshold to do something for the environment is therefore significantly lower. Besides, for electricity we are already at 31.7% Renewable Energy Act, but in heating that is not growing that much yet.



Of course, there are still unresolved problems. And no one really knows where we will be in 10-20 or more years, but society must create incentives.

A gas heating system today can still be there in 50 years (well, renewed 1-2 times) and burn biogas, so-called wind gas or other gas. It then has nothing to do with fossil fuels.

I rather hope that there will be significantly more decentralized combined heat and power plants. They are much more efficient than small-scale systems in every household. They also generate electricity on the side. Whether micro-combined heat and power plants are a solution, I rather doubt.

By the way, from my point of view a great example of more togetherness, but much more ecological action is e.g. the housing cooperative "WEG Am Rundling" in Berlin.

20 houses with 22 residential units (owner-occupied houses and apartments) were primarily built from wood, clay, straw, hemp, linoleum and other ecological building materials modeled on the old Rundling village structures in Wendling. From a common technical basement, the houses are supplied with heating energy, hot, cold and service water as well as electrical energy.

There is also a film about it "Film: A village in Berlin"

Which brings me back to the question of liability in supply contracts or costs in case of a defect, if a member cannot or does not want to pay.

Well, for now you are still allowed to run an island of bliss on your own land.

Well, in principle I think combined heat and power plants or local heating are great, but there is always a third party who wants to earn money, can earn money, and will earn money there. These additional costs must be offset by construction synergies and ongoing savings. This a) rarely works well and b) you are tied in for 10, 20, 30 years. I won’t just convert my house from gas to oil or electricity, but at least you can choose your supplier. With a combined heat and power plant or other local concepts, that is not possible.

In addition, with a [WEG] there are the usual advantages and disadvantages.

At least I don’t have to worry about my island.

It's crazy how often you hear about these conflicts. God, I'm so glad we only have sensible neighbors... who avoid such crap

Combined heat and power plants or local heating are great, but there is always a third party who wants to make money there

So in the example of the Rundling project, it is the community. There is no third party. The homeowners' association (WEG) is the beneficiary and therefore all the owners. Unfortunately, such projects are not very common.

Of course, it is often the case with combined heat and power plants that are built, for example, in the Cologne area, that mainly developers are the ones constructing them to reduce their own costs, to better sell and market the usable area (this has a positive effect on compliance with the Energy Saving Ordinance in such a terraced house). And then the whole thing is forced upon the developer-WEG with a contracting contract for 20 years.

It would be better if an NBG were marketed individually, but then required to come up with a proper concept and be obligated to implement it. So, they need to take care of it and show responsibility. For themselves, the community, and society.

At least I don't have to worry about my island

Somebody has to start somewhere. And yes, evolution rarely happens in one day.

Instead, people rather terrorize each other in NBG with their individual heat pumps (after all, there is more space in the utility room with a split unit) on rather small plot areas.

Unfortunately, the following still predominates:

But it feels like paragraph one, everyone has theirs.
