UTP Cables in Floor with Underfloor Heating: PVC Pipe vs Conduit - Pros, Cons & Installation

So far I managed to get out of running UTP cables in the floor, but this time I have no choice (the devices will be in the center of the room). In addition, there will be underfloor heating. What solution do you propose? I thought about a hard PVC pipe, but it can complicate the heating, while the conduit will be less resistant, although more "configurable" in terms of its track. The second thing - it makes sense to use a tube or conduit (apart from protection against physical damage in time before the screed), since the concrete will get there anyway through the ends (you can possibly protect with foam, but the part outside the tube will be flooded anyway). The only plus I can see is the protection against stretching / shrinking of the cable, which will not have direct contact with the concrete, but the matter of short sections from the end of the tube to the top of the floor remains.

Question: are you going to add anything later? No - a conduit, yes a pipe or even a channel.

I always use a conduit in such installations, it is more convenient to use. I usually try to put the installation in front of the plumbers, usually they put polystyrene on the floor with such an installation.

Certainly, there will not be an additional (the walls will also be flush-mounted and a lot of bends - a long distance), but I am going to introduce redundancy in the form of doubling the number of wires just in case. I'm just wondering how to secure the ends - cram in the wall partially or some other patent?

Exactly here it will be like that - polystyrene, foil and only floor covering.

Do you mean protecting the cable against plastering the walls? Because I don't really understand?

The heated floor makes it easier to guide the pipes or a conduit, because polystyrene is laid. Of course, this must be done before laying the heating pipes. You have to think more about the number or diameter of tubing you will need.

I mean protection against getting inside the spout. Cables from the center of the floor must go to the wall, up and to adjacent rooms above. I thought to remove the conduit at the edge of 20 cm and stick it into the wall, so that the end could be covered with plaster.

I usually stick a metal rod 50-70cm long into the floor and hang the ends on it (making a circle from the stocks). You will have all above the level of the spout placed. On the walls, the installation is usually terminated with installation boxes together in the 230V segment.

We did not understand each other. There will be sockets in the middle of the room, the wires are to run from them to the corner of the room, and from there up - directly to the switch on the 1st floor.

I am talking about it exactly, in the place where the socket will be, you drive the rod (or whatever you want) and attach the wires to it (tape or band). The cable protrudes above the target floor and does not get tangled up between anyone's legs. You will have access to it yourself after installing the central heating and laying the floor.
Something like here:

... you leave an additional line in the conduits, to pull any cables in the future (twisted pair, fiber, coax, etc ...)

If there are many bends and the conduit is small in diameter, nothing will pull in more

if...
but it's worth it, because it costs nothing (well, maybe 10gr) ...

Every installer must know what to do based on his knowledge and experience.

A bit off-topic, but ...

He has to know - doesn't have to - that's why he came here. Provided that he is a network infrastructure installer (question to the author of the thread). I thought we were dealing here with an investor / builder who builds himself / as a house company ...

Now I know what you meant (one picture replaces a thousand words). I thought you wrote about hammering a rod against a wall.

In those short and no bends, that's what I do.

The investor asked me to lay the cable, I do it quite often, but most often my electrician friend, who is currently abroad, used the floor - I focused more on surface installations.
