ᐅ Underfloor Heating: Common Mistakes Made by Professionals When Installing the Loops

Dear forum community,

a warm hello and at the same time an early apology in case I posted in the wrong section, I’m a bit confused and hoping for some advice here.

Our problem: about 10 days ago, a company installed what I guess you’d call "heating loops" in the rooms, meaning insulation – foil – mesh – pipes. Everything has already been connected to the manifolds, so it was done to exact specifications!

Now the screed contractor has noticed that the insulation layer is way too thick and he can’t even apply the minimum required thickness of screed. Of course, we don’t want the screed to crack after a few years... This means: everything has to be removed!!!

MY QUESTION TO YOU: what should we pay attention to now? Is it possible to carefully straighten out and reposition the pipes that were laid in loops and bends? Could this cause cracks? Even our general contractor says he has never seen anything like this.

How can I protect myself? What should I be aware of?

Thankful for your advice,
Klaus

What is the floor structure like? What material are the pipes made of? There are also types of screed that do not require a minimum covering of 4.5 cm (1.8 inches)...

Can the builder not assist you with this question?

If anything, rather an expert... the building inspector has already said that he doesn’t see any problems there.

It only says that the builder has never seen anything like this before, not that it is a problem.

That's true. Sorry. Still, more information would be helpful.
