Hi!

We are about to start the screed installation, and we are uncertain about how to proceed with the floor heating during the curing phase, especially since the general contractor (GC) considers their work done at this point, and the interior finishing will be carried out by subcontractors.

The screed installer sent us this:


Dokument Heizprotokoll fuer Fussbodenheizung mit Zementestrich und Temperaturliste


The flooring installer sent me these:


Formular zur Belegheizung des Estrichs mit Feldern für Auftraggeber, Bauabschnitt und Heizwerte

Foto eines Textformulars mit Tabellen zum Estrich-Protokoll und Temperaturwerten

Dokument mit Protokoll zur Estrichfeuchte und Belegefreiheit sowie Tabellen zur Messung


We don’t need to debate which protocol looks more professional, but the question is which one is actually correct. Everyone insists that their own form is the right one.

The required duration for the curing heating also varies.

What is the best way to handle this?

Asking the GC doesn’t help; they said it’s unnecessary and that if we insist on it, the construction schedule will be extended at our own risk, since the curing heating is not included in the contractually guaranteed construction period. According to them, the curing heating is an old tradition of “older” flooring installers and is basically no longer practiced today. On the other hand, the flooring installer says that “newer” installers do carry it out, as only in recent years has there been a proper emphasis on this. They also said that if we skip it, we must sign a waiver of liability.

I believe it’s clear that curing heating must be carried out. The question is how to decide which protocol to follow and how to get all parties to agree on it?

Now we just have to wait and see what the tile installer requests next. Hopefully, they won’t come up with a third version.

The screed installer performs the functional heating according to DIN EN 1264; this is then followed by the final heating phase by the parquet installer. This should also be documented in the protocol of the final heating phase. Unfortunately, I am unable to read your attachments.

He told me that the heating engineer would do that... seems like it works differently in every project.

Our heating installer took care of this for us, and it went smoothly.

55 or 60°C (131 or 140°F) is definitely excessive for modern underfloor heating and insulated houses! Especially when you are using a heat pump as the heat source anyway.

With proper design, the flow temperature will likely never exceed 35°C (95°F).

The parquet installer says that the form must strictly comply with the requirements of DIN 18356.
