If your house is well insulated then UFH floor temps will seldom exceed
30°C except where covered up. Where you wont be walking on them anyway.

At full winter pelt, my floors are only warm to the touch under the
sofas and the rugs. Stuff that is directly exposed to the air is barely
warm at all. Except where I have ALL the house UFH pipes running down
one short corridor. THAT is a bit warm. But never HOT.
I think you don't appreciate the difference between a square meter of
radiator at 50°C and 30 sq m of floor at 30°C..

This house is pretty well insulated.

But what you seem not to appreciate is the extreme sensitivity that some people have.

She will often go to the kitchen in order to cool her feet down. Whether on the porcelain flooring or using a bowl of cold water. Even when the rest of her feels cool/cold.

30C would be far too high.
