Hello everyone,

Our interior construction is currently in full swing. Right now, the heating and electrical installers are finishing up the rough-in phase.

Next Friday (03/01/2013), our screed will be applied to the three floors (basement + ground floor + top floor, each measuring 8.5 x 10.5 m (28 x 34.4 ft) external dimensions). The anhydrite screed will be pre-mixed and "heated up" by the screed contractor upon delivery.

But here comes the problem: Due to the weather conditions and our decision to build during winter (hindsight is always 20/20), we don’t yet have utility connections installed in the house. This means our underfloor heating system (heating system = gas condensing boiler + solar + controlled ventilation + underfloor heating on ground and top floors, not in the basement) currently cannot be operated through the normal utility connections—and likely won’t be for the next few weeks.

So, I did some research online to see what options are available. I came across several different solutions:

1. Underfloor heating functional heating program using electric boiler alone + window ventilation
2. Underfloor heating functional heating program using electric boiler + construction dryer (dehumidifier)
3. Technical building drying (?)

And there I got stuck. What are sensible alternatives to properly heat up the building (the screed) as part of the drying program? What budget should I plan for? At the moment, I have various contradictory statements about methods and prices, and as a layperson, I’m at a loss.

The above option 1 is estimated by the interior builder to take about 30 days (at roughly 25 € device rental / day plus delivery, pickup, connection fees, electricity costs, and other expenses) and would total around 2000 €.

For the other options, I only have vague information and prices.

Could you please help me out and suggest the best approaches to handle this?

Any tips are greatly appreciated!!!
Thank you very much in advance.

You won’t be able to avoid the scheduled date anyway… the screed installer is apparently already booked.
So just let them install it and don’t expect to start any kind of “drying program” here.
Make sure that nobody walks on your fresh screed during the first few days and that you manage to keep the room at least at +5°C (41°F) without having to enter it yourself.
After that, allow the screed enough time to set and dry before the tiler comes.

Do you have any specific deadlines pressing you? Early spring will still be an ideal period for drying! If your schedule gets too tight, you might still be able to provide technical support then.

Best wishes and good luck
