Is the power consumption and procedure for screed drying normal?

An idea of mine which I recently implemented. While the screed program was running, we wiped the concrete ceilings with a mop, wrung it out, and took it out of the house. In my opinion, this helped a lot, as there were some corners where larger water droplets had accumulated.

I thought the heating engineer comes daily but no way, he will probably only come when the temperature is increased

Why should he come? With me, he just set up the program and then he was done.

By the way: Wipe the damp spots on the window when airing out with an old towel and then hang it outside, it also absorbs a bit of moisture from the most difficult spots.

And even more or longer ventilation! The water has to go outside after all…

For me, nothing was dripping wet. Leave the window tilted open. The heat and moisture have to get out.

15kW? My heat pump only has 3 kW.

Tilted windows are definitely not recommended :-) (Too little air exchange, delayed drying, risk of drafts)

The alternative is to wait 8-12 weeks without heating. But usually, time is more pressing. Why is he doing this with a heating device and not with the intended heater? Has it not been installed yet? Why?
