ᐅ Installing Electric Underfloor Heating in the Bathroom?

Hello,

I heard there are electric underfloor heating systems designed only to keep the floor warm without significantly affecting the room temperature.

For example, I will definitely install tile flooring in my bathroom. I don’t have a regular underfloor heating system and I’m not planning to install one either.

An electric solution that just warms the floor sounds interesting, especially in a bathroom.

Does anyone have experience with this and can share some information?

I assume these systems are simply placed on the screed and then tiled over.

What is considered warm in this context?

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 use too much electricity, I’m also considering tiles with a wood look there.

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

I installed this in the bathroom of a rental apartment. It was about 3 sqm (32 sq ft). It worked well but consumes quite a lot of power. You can expect around 120-150 watts per sqm (11-14 watts per sq ft). The heating time is about 10 minutes before your feet get warm. For a living room, I don't think this is ideal.

This physical phenomenon interests me.
I would guess the idea is a system that doesn’t store heat or transfer it into building components but instead heats up quickly on demand, warming only the surface. It also heats the room, just for a short time.

Why would you do that in a new build? You can just install a standard underfloor heating system in the bathroom, right? The underfloor heating won’t be affected by the higher flow temperature required for the regular radiators in the other rooms.

These are very thin resistance cables that are embedded in the tile adhesive and only warm the tiles. I installed this during a bathroom renovation because it allowed me to keep the screed and only replace the tiles. My tenant is happy with it. It uses a thermostat switch located below the light switch that can control the heating based on time and temperature. The set for 3 square meters (about 32 square feet) cost around 500€ at the time...

However, I would not recommend this for new construction. It’s better to connect the underfloor heating to the return line of the radiator. There are special return valves for this purpose. Still, this is just a workaround...

Hello, no, this is not a new build. It is about a three-quarter full renovation of an old building. I know about the underfloor heating being connected via the return flow from some acquaintances. For me, the floor then feels too warm and uncomfortable. The electric underfloor heating is supposed to only keep the tiles from cold to normal temperature.
