ᐅ Parquet Flooring on Underfloor Heating – Is Thermal Resistance a Concern?

Created on: 24 Feb 2018 21:17

Hello,

We are planning to have oak parquet flooring installed. Today, at the specialist store, we were advised to have the flooring glued down. This supposedly eliminates the need for insulation and is better for underfloor heating. In general, parquet is not ideal for underfloor heating (the heat does not transfer as well as with other floor coverings).

Has anyone had extended experience with this? What should be considered?

By the way, the installation is supposed to cost 30 euros per square meter (about 3.3 square feet) [emoji15]—15 euros for the installation and 15 euros for the adhesive.

Thank you very much for your input.

It simply is not being transmitted.

Oh, I see.

Anyway. We have both solid hardwood flooring and tiles.
In the tiled rooms, the warmth seems to dissipate from the floor somewhat faster. Regardless, wood naturally has a lower thermal conductivity, so its surface feels warmer compared to tiles.

If you assume the house is a closed thermal system (which it obviously isn’t, but ideally would be), then the first law of thermodynamics would suggest so.

However, the question is more related to the second law of thermodynamics. The first law has as much or as little to do with it as with anything else.

Lumpi_LE explained it well: With a better insulator (comparing wood to tiles), you need a higher supply temperature to achieve the same surface temperature. That’s basically it.

Whether the wooden floor stores heat longer also depends on its thickness; often it is thicker than tiles. Without those parameters, you can’t say anything definitive. But it doesn’t really matter:

The parquet floor just needs to be suitable, then it works well. The increase in supply temperature isn’t significant enough to spark a fundamental debate.

@Blondblau: well, if you include everything, it’s not that far off:
Quote from a professional company (not a DIY store):
Solid wood floor board gross price €46.17
Sanding the substrate: gross price €2.62
Glueing gross price €28.56
Initial treatment gross price €10.71
Baseboard gross price €4.28 per running meter
Installing baseboard €4.64 per running meter
Baseboard joints €10.71 per running meter
In total, I arrive at €6,694.58 for 65 sqm (700 sq ft), which equals €103 per sqm (9.60 per sq ft)
