Hello!
We have just replaced our oil burner with geothermal heating. How should I fill in the holes from the filling and venting? There are currently two holes about 5-10 cm wide straight through the concrete. It's getting quite cold... I'm a beginner at house maintenance, so I gladly welcome any help I can get!
Best regards, Linnea

As mentioned, use ready-mix concrete and mix it fairly stiff (less water) so it stays in place instead of running off.
As a temporary solution, you can fill the holes with any cloth. If you or someone around you has some leftover insulation (rock wool, fiberglass), it works excellently.

First check if you don't need more ventilation after the heat source that created circulation has disappeared. Out of the four houses within the family that switched to geothermal heating from oil or oil/wood, three have had a need for increased ventilation and dehumidifiers.
However, the ventilation should not be placed where the old filling pipes were.
You shouldn't use concrete until there are guaranteed above-zero temperatures outside for about a week. Place a flat board against the outside and lean something heavy against it so the concrete doesn't leak out. Then you'll get a good surface afterwards. Until then, as mentioned, just stuff some rags in so it doesn't pull.

Thank you so much for all the answers. Those who were here to fix the geothermal system stuffed in some rags they found. I've seen some insulation lying in a storage room, so I can take some of that and stuff it in for now.
Forgot to mention regarding insulation that some birds like it for their nests. It's probably smart to cover it with something else on the outside.
Speaking of plastering, it's likely the most aesthetically pleasing if there's a plastered base, but it's probably also the hardest if you're a "beginner at house" and asking how to fill holes in the base. No offense to you TS, more a nod to Alexn72. That said, it's not that hard, and it's quite fun so go for it if that's what floats your boat
