ᐅ Dehumidifiers and Desiccant Dryers: To What Extent Are They Needed?

Hello,
the screed has been drying for 8 days, and I am now starting with the dehumidification.
Current humidity level is 95%.

My question:

Is a professional dehumidifier with a capacity of 30 liters per 24 hours plus a smaller unit for a bungalow of 160 m² (1,722 sq ft) and a small dehumidifier for a granny flat of 70 m² (753 sq ft) sufficient?

Additionally, the rooms are being aired by full ventilation (window ventilation) three times a day...
Or should I get another professional device?
I can rent one for 3 euros per day through acquaintances.

Thanks to all

We used four Trotec 166 units (160 m² (1,722 sq ft), two-story) for three weeks.
It worked quite well. The cost was 5 € per device per day.
The units can remove 52 liters (14 gallons) of water in 24 hours under ideal conditions.
It’s important to use devices that allow you to connect a hose for water drainage; otherwise, you’ll have to go to the construction site several times a day to empty the water tank.
Is the heating already running?

The heating will be connected on Tuesday.

Currently, I have a 9 kW fan heater to maintain a base temperature. The house is around 15–17°C (59–63°F).

That works well but costs 50 euros for 170 kWh (580,000 BTU) in 24 hours :-(

I need this temperature because otherwise the additives in the fast-setting screed won’t bond properly.
