Hello everyone,
In about three weeks, we are supposed to finalize our electrical planning on site. Unfortunately, our electrician is somewhat old-fashioned, which makes it difficult for me to collaboratively plan a future-proof electrical setup with him. Therefore, I am currently educating myself to ensure that the networking in our single-family home is fundamentally future-proof.
Basically, it’s about the LAN network... LAN wall outlets are relatively expensive, so proper planning is even more important.
About us:
- Mid to late 20s – couple without children. Planning for 2 children in the near future.
- Single-family house with a usable basement, 2 full floors, and fully equipped with concrete ceilings
- Utility room in the basement with air-to-water heat pump, ventilation system, photovoltaic system
- The router is planned to be located in the office on the ground floor
- The upper floor includes bathroom / bedroom / 2 children’s rooms
- No satellite dish or cable TV — we will use Internet TV exclusively!
Now, I am struggling to network our single-family home sensibly but as cost-effectively as possible.
I have the following questions:
1. Slightly off-topic: In the living room, I would like to have an in-wall conduit installed on the TV wall (the TV will be wall-mounted) so that no cables are visible. Is this sensible and affordable? I will get exact prices from my electrician if this makes sense at all. Would it also make sense to install power outlets at TV height? How do you plan the connections on your media wall reasonably? What should be considered?
Since we plan to use a Magenta TV box and thus IP-TV, a total of four LAN ports in the living room area would presumably be useful, right?
2. How many LAN outlets and especially where should LAN outlets be installed? Mainly: which cable? Is CAT6 sufficient?
→ Such a double LAN outlet certainly costs close to €200, so planning must be really sensible.
Is it really necessary to install 2 double LAN outlets in each children’s room? I always wonder: what is actually going to be plugged in there?
One port for the TV and one port for a multimedia device should be enough, right? So four connections would probably be overkill, correct?
The fact is: It will certainly take years or decades before our children actually use these outlets... Who knows what changes might happen by then? Therefore, could we not cost-effectively use empty conduits (empty pipes) instead?
Is it also possible to “branch off” from an existing double outlet afterward to add more ports for the room? What should be considered here? Or should we consider having an empty conduit prepared in another spot in the room so that a socket can be installed later?
3. How do you solve the “router problem”? Should the one router be placed in the office (ground floor) with LAN outlets in the existing bedrooms upstairs to ensure a stable LAN connection? Or is a router upstairs absolutely necessary?
4. How important are LAN outlets in the utility room? Should the router possibly even be located in the utility room? Because of the concrete ceiling between basement and ground floor, a second router would almost certainly be needed. How should this situation be handled with a basement?
5. What do you think about installing empty conduits for CAT cables in the kitchen / hallway etc. to enable later retrofitting? Is this relatively affordable in new builds?
I would appreciate any feedback so we can make the best possible plans 🙂

How essential do you consider surge protection on a power strip?
An online retailer offers a 9-outlet Brennstuhl aluminum-lined 19" strip for 16 euros, but it doesn’t include surge protection. Proper surge protection starts at the main electrical panel. Once a surge reaches your home’s wiring, a 9-outlet strip in front of your TV won’t do much to protect your devices. Other appliances connected to the electrical network—such as cooktops, refrigerators, lights, and so on—will still be exposed to the full surge voltage. Depending on the surge level, even switched-off light switches can break down, as the isolation gaps aren’t large enough to handle high voltages.
This makes me think—I probably don’t have this kind of protection in my sub-panel either. Thanks for the inspiration!

Everyone should have a surge protector in their subdistribution panel in a modern building nowadays.

But where you’re right, you’re right. Every modern building these days should have a residual current device in the distribution board.How can I install no light actuators at all? Is a KNX actuator withstand high voltage surges?
Edit:
Sorry, I meant withstand voltage transients.

It really depends on the relays used, and there is quite a wide range available here. Alright, let’s leave it at that. Anyone who installs something like this doesn’t worry about whether a 9-outlet power strip costs 16 or 160 EUR (euros). It’s a completely different world for me.
Anyone who installs something like that usually does not have "multi-gang power strips." Because most of the time, the builder/homeowner actually wants to avoid exactly that. But yes, what you are saying is true. You do consider the costs, but you pay for the desired comfort.
