Install electric underfloor heating in the bathroom?

Hi,

I heard there are electric underfloor heating systems that are only meant to keep the floor warm but have little or no influence on the room temperature.
In my bathroom, for example, I will definitely be installing a tiled floor. I don’t have a normal underfloor heating system and there are no plans for one either.
An electric solution that keeps the floor warm is, of course, an interesting thing, especially in the bathroom.

Does anyone know about this and can give me some information?
I assume the systems are simply placed on the screed and then tiles are laid on top.
What is considered warm?
In the living room, I actually want to install a vinyl floor. However, if these electric underfloor heating systems really work well and don’t consume much electricity, I am also considering laying tiles with a wood look there.

So if anyone knows something about this or has personal experience, please share it.

I did that in the bathroom of a rental apartment. It was about 3 sqm. It worked well but consumes quite a lot of power. You can expect about 120-150 watts per sqm. Heating time is about 10 minutes, then you get warm feet. I don't think it's optimal for a living room.

This physical wonder interests me. I would guess the idea is a system that does not store heat or conduct it into components, but quickly warms up on demand and only heats the surface. It also heats the room, just briefly.

why should you do that in a new build? you can just install a normal underfloor heating in the bathroom, right? the underfloor heating can’t be affected by the higher supply temperature for the regular radiators in the other rooms.

These are very thin resistance wires that are pressed into the tile adhesive and only warm the tiles. I installed them during the bathroom renovation because this way I could keep the screed and only had to replace the tiles. My tenant is satisfied with it. It is a [thermostatic switch] under the light switch that can switch depending on time and temperature. The set with 3sqm cost around 500€ back then... In new construction, I wouldn't do that, though. Rather, I would connect the underfloor heating on the return line of the radiator. There are special [return valves] for that. But it is also just a crutch...

Hello, no it is not a new building. It is a 3/4 complete renovation of an old building. I know about the underfloor heating via the return flow from acquaintances. For me, the floor then feels too warm, which I find uncomfortable in my opinion. The electric underfloor heating is supposed to keep only the tiles from cold to normal.
