ᐅ Solid wood parquet on underfloor heating

I just spoke with Meister’s technical support. Regarding the functionality of underfloor heating, it does not matter whether it is installed as a floating floor or glued down. When installed as a floating floor, the underfloor heating system is only slightly slower to respond.

A bigger issue, according to Meister, is the size of the open space. The parquet should not be installed continuously over more than 10m (33 feet). This means that expansion joints in the form of small aluminum strips or cork strips must be placed in the middle of the room if you want to install the floor as a floating floor. If the parquet is glued down, this is not necessary.

Oh yes, that's right, for some it is even only 8 m (26 feet).

There are different opinions on this.
In our case, gluing is planned because it is said that heat transfer between the screed and wood parquet is significantly "worse" when not glued.

My common (healthy?;)) sense, combined with what I learned in school—that energy cannot just "disappear"—tells me that a floating installation behaves as mentioned above (less effective than glued), because: where should the heat go? It stays in the room. 😎

It’s great how thoroughly and quickly we have worked through this topic. I’m impressed! Thanks to everyone!

Since this statement has been repeated, I would like to add that this is not entirely correct.

Ultimately, it’s all about heat transfer, simplified.
First, between the inside and outside through walls, windows, etc.
And second, between the heating system and the interior space.
To compensate for heat loss to the outside, heat must be supplied by the heating system.
If insulation such as impact sound insulation, air layers, (and the parquet floor itself, which has high insulation) slow down or reduce the heat transfer from the heating system into the room, the supply temperature must be higher.
As a result, the system is not only slower but also consumes more energy!
Additionally, this can lead to increased losses, for example through the ground floor slab or basement.

For me, it’s a different matter. It’s not just about the floor being warm. The room needs a certain amount of energy to compensate for losses through walls, windows, and doors. But if the floor cannot transfer this energy quickly enough from the heating pipes to the air, the heating system might not be sufficient. This could mean a higher supply temperature is necessary. How else would insulation in a jacket, a wall, or something similar work?
