Construction costs are currently skyrocketing

This electricity price issue is regionally dependent; there can easily be a 10-15 cent difference between North and South.

Ok then it would tend to be cheaper in the North. But we are rather South. No idea what is connected where and how everything is linked

No idea, apparently the executing company wanted to do it that way. It was a discrepancy. We can choose now.

This is the wording:

"... to offer all buyers the possibility not to have the lines (pipes/cables) surface-mounted in front of the wall in the kitchen, but rather embedded in the floor structure.

Please let us know whether you would like to stay with the surface-mounted option depending on your kitchen planning or if we should carry out the redesign for installation in the floor structure for you!?"

No, the north pays some of the highest electricity prices in Germany. I had to sign a new contract in March and now pay 0.45 c per kWh. I can only dream of your prices.
