Protective conduit for electrical to pex pipe?

[Olf Oggler]

I'm planning to install waterborne underfloor heating in a few rooms in the house. In a couple of places, I will need to run the feed to and from the manifold cabinet in protective conduits. Can you use flex conduit for electricity for this? What is the difference between LK 25mm empty conduit compared to 25mm protective conduit for electricity? The latter is easier to find.

Before anyone points it out, I don't need to lay protective conduit to catch water leakage. It's only to be able to reroute the underfloor heating pipe if needed.

The VVS hose is stiffer and of better quality, whereas the electrical hose crinkles and isn't as stiff on its own.

It can be like that. However, when I feel both variants, I don't notice any obvious difference in quality.

The absolute best flexible conduit for electrical wiring approved for embedding closely resembles the protective pipes used for underfloor heating coils between the coil's endpoints and the distributor. The problem, however, is that there are often incredibly poor flexible conduits for electrical use that will kink, break, kink, etc. If you can feel the conduit in the store and sift out the bad stuff, absolutely.

For shorter distances without too many bends, I wouldn't be worried about using such a conduit. As usual, you get risk minimization and ensure you both push and pull with a suitable draw tape and that the end of the underfloor heating pipe has an appropriately rounded cap.

I would not hesitate to use elslang in such cases.
