ᐅ Retrofitting Underfloor Heating: Experiences

Hello,

we are buying a house built in 1998.
We really like the house, but unfortunately it does not have underfloor heating.
We definitely do not want to do without it.
We would like to have underfloor heating in the living room and kitchen (one room, approx. 48 m² (520 sq ft)) and in the bathroom on the first floor (approx. 12 m² (130 sq ft)). Currently, these rooms have tile flooring.
I have done some research online and found three interesting methods.

1. Milling technique: Remove the tiles (not a problem, as we will probably replace the floor covering anyway). Then a channel is milled into the screed for the pipes. Finally, a leveling compound is applied and the floor can be installed. Any experiences?
2. Uponor low buildup system: Allegedly, this system can even be glued onto the existing tiles. The total height is supposed to be only 10–15 mm (0.4–0.6 inches). Any experiences?
3. Standard heating mat: This system probably makes sense only for the bathroom, as it is usually intended for smaller rooms up to 10 m² (108 sq ft). Experiences?

Has anyone installed any of these three systems? Can anyone share information about the costs and whether it makes sense?

Thank you

When you generate a lot of dirt and adjust the heating to low temperatures, doesn’t it make sense to install underfloor heating throughout the entire house?

Yes, we also wanted to install a walk-in shower. But I’m still not quite sure what is meant by "joining pieces"

Under my old shower and bathtub, there was no screed after removal. So, where the new walk-in shower was installed, the screed would have needed to be redone and connected to the existing screed. However, this can lead to cracking at the joint later on, which is why I completely removed the old screed as well.

PS: I just noticed that you are from OS as well. I’m also based in the OS district.
