ᐅ Is the electricity consumption and procedure for screed drying typical?

Hi everyone,
I’m building with solid construction, and according to the site manager, a construction dryer is needed for the screed drying. So, for the past week, a 15 kW (kilowatt) heater has been running continuously, heating about 270 sqm (2,900 sq ft) at a supply temperature of 35°C (95°F). According to the protocol, you should start at 25°C (77°F), but nobody seems to care.
There is dripping from the walls, and the windows are always wet, like in a sauna.
Will this get better? At some point, all the moisture has to come out, right?
I ventilate twice a day, sometimes even three times, and always remove visible drops.
At 35°C (95°F), the energy consumption is 200 kWh per day. I calculated that over the planned 3 weeks, this will be over 4,000 kWh.
Does this sound about right, or could there be something wrong with the heater?
Moisture is also coming down from above through the precast ceilings—is this normal?
Unfortunately, my site manager is not very proactive, so I’m looking for advice here.
Best regards,
Felix

While the screed program was running, we wiped the concrete ceilings with a wet 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 collected.

I thought the heating engineer would come daily, but no, he probably only comes when the temperature is increased. Why would he come? In my case, he just set up the system and then he was done.
By the way: When airing out, wipe the damp spots on the window with an old towel and then hang it outside. This helps absorb some moisture in the most difficult areas.

15 kW? My heat pump only has 3 kW.
