Hello, dear forum,

we want to install natural stone flooring on the ground floor (slab-on-grade, no basement) of our house. Specifically, travertine tiles measuring 40x40 cm (16x16 inches) with a thickness of 2 cm (0.8 inches) – these come from the supplier’s leftover stock from a hospital construction project.

We are uncertain about how this will work with underfloor heating, as natural stone is usually installed at a thickness of only 1 cm (0.4 inches). The supplier mentioned that although heating up takes longer with thicker stone, the warmth is retained and released for a longer period.

Our planner agrees but recommends installing the heating pipes slightly closer together.

Question: can the 2 cm (0.8 inches) thick travertine be used in the living area without causing us to feel cold during winter? What should we consider? Will there be higher running costs for heating?

THANK YOU!

.. yes .. it’s an excellent heat reservoir ... the plastic pipes for the underfloor heating should be laid with the correct spacing .... who calculated the heating demand? ..

The supplier said that the heating takes longer, but the heat is also stored and released for a longer time.
.... that’s right ... underfloor heating is somewhat “slow” as a heating system anyway ...

What kind of designer is that?

Thanks for the answers!
Our planner is a civil engineer with many years of experience.
The comment about the heating coils was intended to reduce the heating-up time. Does anyone else in the forum have experience with "relatively" thick natural stone? THANKS!
