ᐅ Heating-up phase of the screed / floor screed window position

Good morning everyone,
I have a question:
Next week, after 6 weeks, the screed will be heated up at my place.
My question is, should the space be ventilated during the heating phase?
If yes, should I ventilate once a day by fully opening the windows or keep them tilted open continuously?
I would like to have my windows sealed off already so that the painter can apply the first coat at the end of the heating phase.
Thank you very much.

There is also an option with a hose.
However, I would not prefer that, as these things naturally cost unnecessary money. The painter will tape off the windows themselves for a fraction of the cost of the drying units ;-)
Especially in winter, building drying is rather a manageable task.

Well then, congratulations on emptying it every hour ;-)This problem can be solved with a hose.Ventilating three times a day can be cheaper and better for the environment.
But only if you don’t drive there by car. 😉

Hausbau 552 Dec 2021 16:48Starting next Tuesday, we will begin heating the screed in our KfW Efficiency House 55 EE (bungalow, 90 m² (970 sq ft)). I have already received the heating protocol. Looking at the required temperatures and their gradual increase up to 60°C (140°F), where they must be maintained for three days, is simply daunting. Additionally, this heating process will be done entirely with direct electric heating. The heat pump (if it can even be used for the heating process) is unfortunately not yet with the heating contractor.

The idea of needing to raise the temperatures up to 60°C (140°F) flow temperature and maintaining that for three days is just dreadful. That really is dreadful. Why so high? Normally, it should be sufficient to go up to the design temperature of the underfloor heating. Maybe a few degrees higher as a safety margin, but 60°C (140°F) is quite extreme.

On top of that, this heating will be done entirely by direct electric heating. Unfortunately, same here. Mainly because our heating technician is being difficult, not because the system itself lacks the required equipment…
Questioning the 60-degree approach. It’s just expensive and doesn’t provide any benefit.
We have a brine-to-water heat pump with borehole drilling. The drilling company refused to heat up using the probe, as this is generally avoided due to warranty reasons. I would have liked to use the probe and heating rod simultaneously to reach about 12kW.
Heating the 2°C (36°F), cold, and damp shell using only a 6kW heating rod in January simply didn’t work well enough, so we used an electric heater connected to the underfloor heating system. It had around 20kW. That worked fine but involved costs for the device, installation, and the electrician also expected a tip for the (temporary) CEE32 socket inside the building. Unfortunate, but what can you do.

That’s really awful.
Why so high? Normally it’s enough to match the design of the underfloor heating system. An interesting statement. What is the source of this information?
What exactly does “design of the underfloor heating system” mean? If the supply temperature for functional heating is set to 60°C (140°F), then the heating system must also be designed accordingly.
How should the comment "... normally it’s enough to match the design of the underfloor heating system" be understood in this context?
