ᐅ Heating Program Procedure After Screed Installation

Hello everyone,

We need your help as we believe there might have been an issue with our heating program or the process.

Below is a brief summary of the steps since the screed was laid:

1. September 6–7, 2018: Screed laying (cement screed in a two-story building)
2. September 14, 2018: Start of ventilation (morning and evening)
3. October 5, 2018: Start of heating phase
4. October 6, 2018: EA/49 error (according to the plumber, possibly air in the gas line, nothing unusual)
5. October 14, 2018: 35°C (95°F)
6. October 16, 2018: 45°C (113°F)
7. October 17, 2018: 50°C (122°F)
8. October 18, 2018: 52°C (126°F)
9. October 19, 2018: 52°C (126°F)
10. October 22, 2018: 50°C (122°F)
11. October 23, 2018: 26°C (79°F)
12. October 24, 2018: 20°C (68°F)
13. October 25, 2018: OFF

Now to the main question: Is this sequence okay? We thought the temperature should increase in 5-degree increments?

Could this damage the screed? Is there anything we can do or check?

Thanks in advance!

Good luck

The heating schedule should be preset in modern/new heating systems. You just press the button, and then it runs for 14 days straight.
Did you not set up any drying fans before?

Most people haven’t installed the heating system by the time the screed is poured. After all, it needs to be placed somewhere.

What do you mean? A heating system has heating phases, and the OP is asking whether the program is set up correctly.

I don’t understand the statement either...

We didn’t use any construction dehumidifiers. Before starting the heating program, the house had already been well ventilated and dried. Of course, heating it up caused some additional moisture to be released from the screed, but everything was within normal limits.

My concern is really only about the timing and the stages of heating up and cooling down.

Well, you can make a science out of it... basically, it’s enough to just keep the heating running. In the end, the moisture level under the floor coverings has to be right, and then the heating should be turned off.
