ᐅ Installing wide plank flooring over existing tiles and underfloor heating?

Hi everyone,

We would like to install oak country-style floorboards. The rooms have underfloor heating, and the floors are tiled. Can we lay the floorboards directly over the tiles? What issues might arise? Higher energy costs or just slower floor warming? Should we install them as a floating floor or glue them down? Does anyone have any experience with this? We would prefer to avoid the effort of removing the tiles and leveling the floor. But if there are valid reasons to do so, we are willing to proceed...

A valid reason could be adjusting the doors. Or that the patio door no longer opens because the floor structure is too high. Or something else doesn’t fit if the floor suddenly is 20mm (0.8 inches) higher.
Are the tiles smooth and level enough? Because the floorboards would only be glued down and not installed as a floating floor.

Yes, everything fits. But I have noticed that many people remove the tiles beforehand or cover them with leveling compound. And I wonder why.

There are various reasons. For example, if the tiles don’t fit properly or the floor is too uneven, something needs to be done. Or to avoid efficiency losses in the underfloor heating system (old underfloor heating, large spacing between pipes – then the heating has to work harder to raise the room temperature, e.g., during morning setbacks, or with old/small tiles having many grout lines, a lot of air remains under the floorboards). Or some people don’t like having to shorten 8 doors (which also costs money and can feel awkward for tall people – very subjective).
And so on – there are plenty of reasons.

Our children applied the filler to install a designer floor. I was skeptical, but it works.
I definitely wouldn’t do this with hardwood flooring because I would be concerned about the heating properties.

I wouldn’t want to deal with squeaking doors—and how does the parquet fit under the door frames? Steps at the transitions to rooms where tiles remain (bathroom, etc.) and the uncertainty about how the heating will work…..
