Is it possible to combine floor heating with wooden floor? Yes, although with some exceptions it is necessary to know before placing the wood.

Underfloor heating is no longer a big question and more and more people are asking about this type of installation. It is a network of pipes under the pavement, through which water circulates at a temperature higher than that of the environment.

Among its advantages are:

  • Low consumption and good performance.
  • The installation is hidden, leaving free space for other uses and even complementary systems.
  • It can also be used to cool the environment.
  • Traditional and also renewable energy sources can be used.
  • Create an environment of comfort. It does not produce drafts, dryness of the environment or humidity.

But heated floors also have limitations:

  • The installation is relatively complex, requires work and is not particularly economical. Although it is profitable in the long run.
  • Not all floor materials are suitable.

Wood and heated floors

  • The question is clear: can wood be used for floor heating?
  • And the answer too: Yes.
  • But, can any wood be used in any way on a heated floor?
  • Do not.

Wood is an excellent material with very good performance, but its installation in some situations requires a certain measure. It is a natural insulator, and also with changes in temperature and humidity it contracts and expands. These characteristics may raise some doubts about the suitability of wood for floor heating, but considering some issues, there should be no problems.

As for the loss of efficiency of the wood-based heating system, it must be said that this loss exists. Most installers speak at 10%. This, although it is something, is not a percentage to avoid using wood on heated floors. On the other hand, it must be said that all materials have some resistance, the efficiency of the whole and not just a material being important.

On the other hand, wood maintains its temperature for much longer after the heating is switched off than other materials, such as ceramic. This is known as thermal inertia.

How is the wood laid on the underfloor heating?

The UNE 56810 standard establishes the steps and criteria for installing wooden floors. According to this, the temperature must be raised gradually, and the radiant floor must be turned off before installing the parquet, the floor must have a humidity of approximately 2%.

In this situation, the best for a radiant floor is:

  • Choosing woods for floor heating: Use little nervous and stable species, with density greater than 650 kg / m3, and with good stability against humidity. Some woods such as maple, beech or jatoba are not recommended.
  • Avoid thicknesses greater than 15 mm.
  • Attach the wooden platform to the table with glue that allow the transmission of heat and prevent its movement. And also with good and lasting elasticity.

What about laminate floors and underfloor heating?

Floating floors are not incompatible with underfloor heating, although some issues should also be taken into account.

  • The choice of blanket or insulation is essential. Not just anyone. It is recommended that you have an aluminum vapor barrier on the upper side, so that it does not let moisture in and distributes the temperature evenly. In addition, it must have a very low thermal resistance.
  • Regarding shutters, most laminate flooring manufacturers and brands have models suitable for floor heating. These normally have a higher density, reducing the thermal resistance and also the expansion and contraction coefficient.
