The power connection is regulated by the TAB of the supplier and your application to the grid operator. Depending on the devices and demand, you will be max secured. For example, there is more with heat pumps and a car charging station must also be applied for. Such a Powerwall will turn the whole street dark.

Water will be a Qn=2.5, a completely normal water connection with the standard basic fee. Unless you have a 20m pool and filters that need to be flushed 3 times a week with x cubic meters....

Gas?! No idea.

The usual house connection has 50A (is being applied for), the meter fuse is then 35A, for the construction power I would make a 63A meter fuse, so apply for 80A.

For water and gas, I would choose the minimum standard (you "only" have 120sqm of living space! For electricity, possibly upgrade to 63A fuse (80A) if the additional cost is low. Keyword electric car. The wallboxes also work with a normal 50A connection, but if you have two of them, your connection won’t be overwhelmed. However, I would make that dependent on the additional cost charged by the provider. Usually, there is also a construction cost surcharge on the bill, which can quickly cost four figures. Just ask again.

And what about the water of the total flow rate VR / peak flow rate VS

The peak flow rate Vs is calculated from the total flow rate Vr. According to DIN 1988, this is divided into so-called usage units NE. An NE can be, for example, a kitchen, bathroom, or utility room. Used in a formula, this results in Vs.

This is important in residential construction or larger construction projects. For a construction project the size of a single-family house, a PE-x pipe with an outer diameter of 32 mm is sufficient.

You need to first consider which devices you want to supply later via your gas connection and whether they might run simultaneously.

For example, a modern condensing boiler should manage with a 15 kW connection power.
If you then want additional devices, you have to check what they consume.

- Gas fireplace: 4-10 kW
- Gas stove: ~15 kW
- Grill with natural gas connection: 10-40 kW (depending on size and number of burners)
- Heater with natural gas connection: 7-15 kW

If you assume that you do not grill in the deepest winter (there are supposedly some strange people like that), but stove and fireplace are fueled by gas, you need a 40 kW connection (15+10+15)
