Yeah, well, I wouldn't put any stock in what some internet retailers offer. In any case, it is no longer available directly from Viessmann like that, why would he lie to us, it doesn't benefit him either.
We also signed the offer for the electrical work there, but now we want to do 80% of it ourselves since my cousin is an electrician. This was rejected because we signed a contract and if we don't comply, we have to pay a contractual penalty. Therefore, I am not willing to make many concessions to the company now.
Then just compromise on the electrical work, so that everyone benefits?
So, speaking very generally, I want to know my negotiating position in advance...
If I buy an item and it is no longer available, do I automatically have the right to a more expensive replacement item or do I have to accept an alternative or an additional payment?
As far as I know, the article explicitly stated in the contract must also be delivered. If Viessmann has now discontinued the sale, the provider is not to blame, unless they have known for a longer time. However, they are obliged to deliver a comparable replacement article. I would not agree to a deal with the [Elektrovertrag]. You will come off worse there.
The terms and conditions _must_ be somewhere! And something like that is definitely called force majeure or something similar.
But you can also negotiate with the electricity company. Being stubborn pays off little here, rather some diplomacy :)
