ᐅ Screed - Drying Process Interrupted, Is This a Problem?

Hello,
(I hope I am in the right sub-forum),

Calcium sulfate screed (Knauf FE50) was installed in our house. After about 7 days of drying, the MobiHeat system was started. After rapid and strong heating, the house was cold again after 2 days. The MobiHeat unit was probably defective, so a replacement was installed, but it still does not work. (The temporary site power distribution box is now claimed to be the problem.)
-> What could have happened? Could the screed possibly be damaged? How can I, as a layperson, check this?

Best regards

The damage will mostly affect your wallet. If you restart the program from the very beginning, nothing should go wrong.
Heating up quickly and intensely would actually be the issue here. Normally, the temperature is raised gradually to allow moisture to escape from the screed.

Are you referring to the temporary electricity costs at the construction site?
The long-term rental cost for the equipment doesn’t really concern me; that’s the general contractor’s responsibility. By "rapid," I meant about 24–36 hours. It did seem a bit fast to me as well... Thanks!

Has the screed possibly been damaged?
Answer:
Screed is generally unaffected by whether it is heated gradually or not!
Therefore, no damage can occur if it is heated intermittently.
However, the topic of "functional and covering heat curing" is quite different!
My advice:
Once the heating system is working again, run the entire heating program according to the prescribed heating schedules.
Two or three days after the heating phase, heat again at full temperature for one day, as much as the system allows.
Regularly ventilate the room briefly to allow moisture from the screed to escape to the outside air.

Thank you very much for the information.

Who pays for the temporary construction power, you or the general contractor? Now I still need signs.
