ᐅ Underfloor heating: wet or dry installation?

Hello everyone,

like many of you, we are currently in the planning phase of our house building project.
After numerous discussions with different builders, we still don’t know which method is best for installing underfloor heating. Some prefer the wet installation method, while others swear by the dry installation method. For example, which option offers better thermal conductivity? What are your experiences? We want to install vinyl flooring and can’t understand why wet installation with bonding the vinyl surface should be disadvantageous...

Best regards, Tu Hus

Silly question: What is a wet installation? I’m serious, because I have never heard of or seen anything like that before.

Installed in flowing screed, the pipes are fully enclosed. The dry method uses drywall panels, leaving air space around the pipes.

How exactly should I visualize an underfloor heating system "installed in dry construction panels"? I can’t quite picture that.

From what follows, it seems that it was installed as a wet system (although this is not mentioned anywhere).

Hello

Underfloor heating in dry construction is often installed in polystyrene panels with pipe channels. For better fixation and to improve upward heat radiation, the straight lengths are clamped in omega-shaped metal plates.
You might want to look up Velta Siccus or Uponor Siccus.

Oh, I see.....
If the build-up height allows, I would choose a build-up with wet screed.
With limited build-up height, for example in renovation cases or when finishing the attic, the dry construction version is also an option.
