Hello everyone,
I am currently in the final phase of building my house and would like to get some other opinions on the topic mentioned above.
In our case, the screed was installed on July 24th. Tiling began on August 20th. However, the tiles were laid with a decoupling membrane because we have still not been able to turn on the heating. This week, our gas meter is finally scheduled to be installed, so we can start using our underfloor heating. The tiler told us that we are only allowed to turn it on at the earliest four weeks after the tiles are installed, and even then, only gradually.
My question is whether this is correct and what exactly is meant by heating up slowly. Does this mean a few days or several weeks? Also, I would like to know if it is a problem that the screed was not dried by the underfloor heating, or if this still needs to be done later. What do the experts among you think about this?
I would appreciate your responses.

I spoke with the tiler 30 minutes ago.
He didn’t perform a CM measurement because the surface was decoupled. Special mats were installed specifically for this reason, as they make the residual moisture irrelevant. I recall they were orange mats with small air holes. According to him, there should never be any problems because of this.
PS: I do have one more question. We didn’t have tiles installed on the upper floor. Can I assume that the screed there is dry after 65 days so that I can install flooring?

Please measure accurately. There is no other certainty besides allowing plenty of time.
With synthetic coverings, you trap moisture inside, which can damage wood. Even if someone else might be responsible for the coverings, I wouldn’t take that risk.
PS: The issue with the tiles is already water under the bridge anyway.

Take some good-quality yTape. Stick some cellophane on the screed at various points. Make sure it’s completely sealed all around. Wait one day. Is there any water underneath? Then be careful. If it’s dry underneath, then you’re clear to go ahead with Marzipan. That’s how we did it before installing the vinyl.
