Baseboards for heating pipes

I am planning the installation of a gas condensing boiler in a two-family house. The new heating system is intended to replace the approximately 19 existing electric night storage heaters.

There would now be the elaborate option of laying the required pipes in the screed. However, the entire floor would have to be opened, which partly consists of marble and solid wood parquet. The heating engineer offered to do this with a special baseboard. Now to my question:

Who has experience with this? Can you send me pictures of how it looks? Do you know of any quality manufacturers of such baseboards? I am looking forward to reading about your experiences.

Hello Hello

In specialist trade it is called "HZ - Profil"
offers various solutions for different cable routes
and is available in various finishes.
Properly executed, it almost looks like new construction afterwards, only the walls should not be too uneven.
