Hello everyone,
Our cement screed was heated in 5°C (9°F) increments from 25°C (77°F) to 50°C (122°F). The 50°C (122°F) was maintained for 12 days, although it didn’t always reach 50°C (122°F). The workers ventilated frequently, which caused the floor to cool down more, making it difficult to maintain 50°C (122°F). Additionally, there was still some moisture in the screed at the beginning.
Our flow temperature should be a maximum of 35°C (95°F), so the 50°C (122°F) should be acceptable. However, I have the following questions:
1. Does it have any negative effects if the temperature fluctuated between 48°C (118°F) and 50°C (122°F) during heating?
2. Someone told me that the screed temperature during heating should exceed the flow temperature. In other words, since our flow temperature is 35°C (95°F), the screed should also reach 35°C (95°F) during heating. Is that correct? Because I am not sure if this was achieved. Maybe for 1-2 nights, but during the day the screed temperature was around 31°C to 33°C (88°F to 91°F) due to ventilation.
Best regards

Vicky Pedia22 Mar 2020 00:22@M. Gerd The manufacturer has already programmed heating schedules. "They’ve got that covered." The main purpose is to check whether the system is airtight and if the screed is drying evenly (functional heating). So just sit back and watch ...
If only it were that simple... At first, the heating didn’t work until we realized that a fuse for the temporary construction power had blown. Both the device manufacturer and the heating installer were certain that if a fuse for the high-voltage supply had blown, leaving only two phases available, the device simply wouldn’t start. But that wasn’t the case...
Then there was dripping from the ceiling, and I suspect a leak somewhere in the underfloor heating system, but that would be off-topic here, so there is a separate thread about it
