Organize construction electricity/construction water yourself?

Especially at the current temperatures, the heating element is hardly necessary

You mean the 0°C of the last few days?

Exactly, it's nothing - the design temperature is usually -10/-12.

That's nonsense, it runs over both media.

No one would make that a rule purely for pleasure. And I would also initially rule out that the heat pump manufacturers or the probe producers have a secret agreement with the electricity suppliers. The argument that there is a significantly higher heating load during screed drying than during standard operation seems plausible to me. That the probes and the surrounding soil freeze during this enormous load over several weeks would not surprise me. It is probably not to be excluded that something could be damaged by this frost damage. Standard operation is roughly: first, after a warm summer, the heating can rely on the heated house and ground for months. Then only the energy lost daily must be supplied. I would guess (without any knowledge) that standard operation requires only 20-30% of the power compared to screed drying. Is there anyone here who can professionally assess this?

I have learned from the geothermal probe company that screed drying must basically not be carried out via the heat pump/probes (the probes could be damaged due to the high load), but only via the electric heating rod.

**Basically, there is a risk of freezing of the ground due to the permanent high heat extraction during screed drying, which cannot regenerate even over the summer, possibly leading to the temporary unusability of the geothermal collector / geothermal probe.

All our BU, where a heat pump is installed as a heat generator, use mobile heating devices and thus do not assume any warranty risk.

**Source: since I cannot phrase it that way myself, I borrowed the sentence from Wolf® "Notes on screed drying."

Rhenish greetings

A screed drying program, when executed correctly, does not run at full power for weeks - and it is always a combination of both media.

And I said, you should keep an eye on the probe temperatures - there is also no rule that says you are not allowed to do that.

And I said, you should keep an eye on the probe temperatures

But how is that supposed to work? I observe that and notice the temperature is dropping towards 0°C. Do I then call the heating installer to adjust the program? Am I not solely responsible at that moment to ensure that everything goes well and remains intact?
