Underfloor heating - Better to install tiles or laminate?

What is included in your 120sqm?

And the installation price cannot be stated as a flat rate, it depends on the size of the tiles.

I don't notice any difference between tiles and laminate. The laminate in our home is clicked together. The underfloor heating runs at such a low temperature anyway that you can't even feel the warm floor. I don't know the heat transfer coefficients, but with such a low temperature difference, I don't believe there are major differences. What I would never do is laminate in the kitchen.

We now want to try and glue vinyl. We don’t really like tiles. They are too cold for us and if something falls, it breaks. It doesn’t seem too complicated. We’ll start in the basement and practice there already [emoji16]

I am looking forward to experiences, I will also have 80 sqm later.

Tiles are generally better for underfloor heating in terms of heat conductivity and distribution.
Laminate (wood + impact sound insulation) naturally insulates against heat. Not by much (necessarily). Most say they don’t notice a difference. Some say it doesn’t insulate either, it only delays the heat transfer, meaning laminate would be slower to respond to temperature changes. I personally believe that overall less heat arrives in the long run, even if it’s just a small 0.5° that I’m talking about.

Our tiler charges a little over €30 net per m² for installation.
Almost €10 net surcharge per m² for tiles larger than 30 x 60cm (which I consider outrageously expensive).
For a room of about 15-20m² of laminate, I once took about 3 hours with my father-in-law, without impact sound insulation, without baseboards.

Cheaper is of course the good and affordable laminate for €20, which is then installed by yourself.
Whoever can lay tiles won’t hesitate long and will lay tiles themselves.
Otherwise, we laid tiles where there is a lot of wear and tear. A bedroom probably has to endure fewer tramplings than a living room or hallway. So we have tiles there too, and laminate in the bedroom, both with underfloor heating.

Some say it doesn't insulate either, it only delays the heat transfer, meaning laminate would be even slower to respond to temperature changes.

Help. These some should then explain exactly what insulation is!?

The worse heat is conducted, the warmer the underside of the floor becomes when the same amount of heat reaches the surface (when comparing identical material thicknesses). And the longer it takes.
