Floor plan planning shortly before submitting the building application

It's a pity it has to come to this. Maybe the GU just gambled that it wouldn't come to this

I think so too. Most customers will probably be appeased with this and remain believing that the "experts" must be right.

The circulation in the children's bath must be an additional pump to prevent turbulence. So the price of just over €800 is also final. Alternatively, they say you have to wait about 30 seconds for warm water (3 liters are in the line, the washbasin faucet lets through about 6l / min). I still have to check for the shower. That's annoying.

What is this nonsense? What vortices? Outrageous... A circulation pump will be installed, and that's that.

A circulation pump will be installed and that’s it.

It was also offered. Included in the €870 are:

"Circulation pump with check valve, piping with insulation"

But there is already a circulation pump installed in the house, right? It's nonsense that he needs a second pump for that. One circulation pump is installed per hot water network and associated circulation. NOT 2.

If there was no circulation installed/planned before, that's a different matter.

Yes, it is installed. But since it is further away, it is advised not to use it. I will order it that way; I can't clarify it any other way quickly. But that's not a problem, because that way I can also program the things differently.
