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

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.

I don’t understand the calculation. Surely, you wouldn’t pay 30 euros just for the adhesive. The 30 euros includes the labor costs.

It says 15€ for the adhesive and 15€ for labor. How do you end up with 30€ just for the adhesive?

For comparison:
We pay 22€ for installation including adhesive.
But that was also renegotiated.

By the way, online you can find adhesive (PCI or Wakol) for about 5-6€/sqm (square meter).

It is true that hardwood flooring takes longer to warm up compared to tiles. However, it also retains heat for a longer period – so theoretically, you could lower the heating earlier than with tiles because the hardwood does not cool down as quickly.

Have you asked the flooring installer about solid hardwood? It often isn’t more expensive.

That is not entirely correct. Wood, including parquet, is a poor heat conductor and also a poor heat store. If you lower the heating, the surface will cool down faster than stone. The best heat conductors are tiles. They also retain heat longer, as seen with soapstone stoves.

Whether parquet is suitable for underfloor heating depends on the specific product. The installation method (such as gluing) is also specified in the product details.

In all physical and heating-related matters, a completely incorrect statement @aero2016 ...

Basically, it is not a problem, but slightly higher supply temperatures are required, which leads to increased consumption. However, this should not be a major concern.

Not necessarily. It depends on the heating system. With an air-to-water heat pump, you are, of course, correct.
